Enhanced area feature is a new feature defined in eMMC4.4 standard. This
user data area provides higher performance/reliability, at the expense
of using twice the effective media space due to the area using SLC.
The MMC driver now reads out the enhanced area offset and size and adds
them to the device attributes in sysfs. Enabling the enhanced area can
only be done once, and should be done in manufacturing. To use this
feature, bit ERASE_GRP_DEF should also be set.

Note that this patch also makes 2 changes to the code paths for the f71889fg
to keep the code unified between the 2 (for simplicities sake). Both of these
are harmless for then f71889fg:
1) The first change is to always set the FAN_PROG_SEL bit to 0. This influences
accesses to some banked fan / pwm registers. On the f71889fg no registers
which we use are banked. On the f71889ed however some more fan registers
have been banked including one which we use, by making the FAN_PROG_SEL bit
0, address 0x96 will point to the right register.
2) The second change is to see a FANx_TEMP_SEL value of 0 as pointing to
a PECI / AMDSI value, and thus disable our pwm related sysfs attr.
This is correct for the f71889ed and on the f71889fg 0 is a reserved
value, so we should never see it and if we do, disabling the pwm related
sysfs attr is a sane thing to do.

The code handling system-wide power transitions (eg. suspend-to-RAM)
can in theory execute callbacks provided by the device's bus type,
device type and class in each phase of the power transition. In
turn, the runtime PM core code only calls one of those callbacks at
a time, preferring bus type callbacks to device type or class
callbacks and device type callbacks to class callbacks.
It seems reasonable to make them both behave in the same way in that
respect. Moreover, even though a device may belong to two subsystems
(eg. bus type and device class) simultaneously, in practice power
management callbacks for system-wide power transitions are always
provided by only one of them (ie. if the bus type callbacks are
defined, the device class ones are not and vice versa). Thus it is
possible to modify the code handling system-wide power transitions
so that it follows the core runtime PM code (ie. treats the
subsystem callbacks as mutually exclusive).
On the other hand, the core runtime PM code will choose to execute,
for example, a runtime suspend callback provided by the device type
even if the bus type's struct dev_pm_ops object exists, but the
runtime_suspend pointer in it happens to be NULL. This is confusing,
because it may lead to the execution of callbacks from different
subsystems during different operations (eg. the bus type suspend
callback may be executed during runtime suspend of the device, while
the device type callback will be executed during system suspend).
Make all of the power management code treat subsystem callbacks in
a consistent way, such that:
(1) If the device's type is defined (eg. dev->type is not NULL)

The platform bus type is often used to handle Systems-on-a-Chip (SoC)
where all devices are represented by objects of type struct
platform_device. In those cases the same "platform" device driver
may be used with multiple different system configurations, but the
actions needed to put the devices it handles into a low-power state
and back into the full-power state may depend on the design of the
given SoC. The driver, however, cannot possibly include all the
information necessary for the power management of its device on all
the systems it is used with. Moreover, the device hierarchy in its
current form also is not suitable for representing this kind of
information.
The patch below attempts to address this problem by introducing
objects of type struct dev_power_domain that can be used for
representing power domains within a SoC. Every struct
dev_power_domain object provides a sets of device power
management callbacks that can be used to perform what's needed for
device power management in addition to the operations carried out by
the device's driver and subsystem.
Namely, if a struct dev_power_domain object is pointed to by the
pwr_domain field in a struct device, the callbacks provided by its
ops member will be executed in addition to the corresponding
callbacks provided by the device's subsystem and driver during all
power transitions.

Currently, wakeup sysfs attributes are created for all devices,
regardless of whether or not they are wakeup-capable. This is
excessive and complicates wakeup device identification from user
space (i.e. to identify wakeup-capable devices user space has to read
/sys/devices/.../power/wakeup for all devices and see if they are not
empty).
Fix this issue by avoiding to create wakeup sysfs files for devices
that cannot wake up the system from sleep states (i.e. whose
power.can_wakeup flags are unset during registration) and modify
device_set_wakeup_capable() so that it adds (or removes) the relevant
sysfs attributes if a device's wakeup capability status is changed.

Change the default UBIFS behavior WRT data CRC checking. Currently,
UBIFS checks data CRC when reading, which slows it down quite a bit,
and this is the default option. However, it looks like in average
user does not need this feature and would prefer faster read speed
over extra reliability. And this seems to be de-facto standard that
file-systems do not check data CRC every time they read from the
media.
Thus, make UBIFS default behavior so that it does not check data
CRC. This corresponds to the no_chk_data_crc mount option. Those users
who need extra protection can always enable it using the chk_data_crc
option.
Please, read more information about this feature here:

Add an "overwrite" trace_option for ftrace to control whether the buffer should
be overwritten on overflow or not. The default remains to overwrite old events
when the buffer is full. This patch adds the option to instead discard newest
events when the buffer is full. This is useful to get a snapshot of traces just
after enabling traces. Dropping the current event is also a simpler code path.

The idea behind this option is targeted at developers who, in the
process of writing their code, want to do the occasional
make W=1 [target.o]
and let gcc do more extensive code checking for them. Then, they
could eyeball the output for valid gcc warnings about various
bugs/discrepancies which are not reported during the normal build

When a DNS resolver key is instantiated with an error indication, attempts to
read that key will result in an oops because user_read() is expecting there to
be a payload - and there isn't one [CVE-2011-1076].
Give the DNS resolver key its own read handler that returns the error cached in
key->type_data.x[0] as an error rather than crashing.
Also make the kenter() at the beginning of dns_resolver_instantiate() limit the
amount of data it prints, since the data is not necessarily NUL-terminated.
The buggy code was added in:
commit 4a2d789267
Author: Wang Lei <wang840925@gmail.com>
Date: Wed Aug 11 09:37:58 2010 +0100
Subject: DNS: If the DNS server returns an error, allow that to be cached [ver #2]
This can trivially be reproduced by any user with the following program
compiled with -lkeyutils:
#include <stdlib.h>
#include <keyutils.h>
#include <err.h>
static char payload[] = "#dnserror=6";
int main()
{
key_serial_t key;
key = add_key("dns_resolver", "a", payload, sizeof(payload),
KEY_SPEC_SESSION_KEYRING);
if (key == -1)
err(1, "add_key");
if (keyctl_read(key, NULL, 0) == -1)
err(1, "read_key");
return 0;
}
What should happen is that keyctl_read() reports error 6 (ENXIO) to the user:
dns-break: read_key: No such device or address
but instead the kernel oopses.
This cannot be reproduced with the 'keyutils add' or 'keyutils padd' commands
as both of those cut the data down below the NUL termination that must be
included in the data. Without this dns_resolver_instantiate() will return
-EINVAL and the key will not be instantiated such that it can be read.
The oops looks like:

The setting group_isolation=0 was because by default we idle on

Add a commandline parameter "threadirqs" which forces all interrupts except
those marked IRQF_NO_THREAD to run threaded. That's mostly a debug option to
allow retrieving better debug data from crashing interrupt handlers. If
"threadirqs" is not enabled on the kernel command line, then there is no
impact in the interrupt hotpath.
Architecture code needs to select CONFIG_IRQ_FORCED_THREADING after
marking the interrupts which cant be threaded IRQF_NO_THREAD. All
interrupts which have IRQF_TIMER set are implict marked
IRQF_NO_THREAD. Also all PER_CPU interrupts are excluded.
Forced threading hard interrupts also forces all soft interrupt
handling into thread context.
When enabled it might slow down things a bit, but for debugging problems in
interrupt code it's a reasonable penalty as it does not immediately
crash and burn the machine when an interrupt handler is buggy.

This allows to load the OF driver based informations from the device
tree. Systems without BIOS may need to perform some initialization.
PowerPC creates a PNP device from the OF information and performs this
kind of initialization in their private PCI quirk. This looks more
generic.
This patch also avoids registering the platform RTC driver on X86 if
we have a device tree blob. Otherwise we would setup the device based
on the hardcoded information in arch/x86 rather than the device tree
based one.

History:
v1..v2:
- dropped device_type except for cpu & pci. I have the compatible string
for pci so I can drop the device_type once it is possible
- I lowercased all compatible types. I will need to resend some patches
which have upper case intel
- The cpu had the same compatible string as the soc node. So I added to
the soc node -immr for internel memory mapped registers.
- I added generic names for all parts.
- I reworked the i2c bars matching the way you suggested. I added a
compatible node for the PCI device which only the PCI ids in its
compatible string. The bars (each represents a complete i2c
controller) have a "intel,ce4100-i2c-controller" compatible node. It
is not used by the driver.
The driver is probed via PCI ids (by the pci subsystem not OF) and
matches the bar address against the ressource in the child node. Once
there is a hit the node is attached.
- The SPI driver is also probed via pci. However I also attached a
compatible property based on PCI ids
v2..v3:
- intel,ce4100-immr become intel,ce4100-cp. cp stands for core
peripherals. The Atom data sheet talks here about ACPI devices. Since
we don't have ACPI this does not apply here.
- The interrupt map is gone. There are now plenty of device nodes.
- The "unit address string" got fixed, it uses not DD,V format.
v3..v4:
- added descriptions for compatible nodes introduced here:
- intel,ce4100-ioapic
- intel,ce4100-lapic
- intel,ce4100-hpet
- intel,ce4100
- intel,ce4100-cp
- intel,ce4100-pci
- added a description about I2C controller magic.
- Added gpio-controller and gpio-cells property to gpio devices. Those
properties are not (yet) used.

This patch adds minimal support for device tree on x86. The device
tree blob is passed to the kernel via setup_data which requires at
least boot protocol 2.09.
Memory size, restricted memory regions, boot arguments are gathered
the traditional way so things like cmd_line are just here to let the
code compile.
The current plan is use the device tree as an extension and to gather
information which can not be enumerated and would have to be hardcoded
otherwise. This includes things like
- which devices are on this I2C/SPI bus?
- how are the interrupts wired to IO APIC?
- where could my hpet be?

It is not very important due to low maxium data size of text, but

Update the memory sysfs code such that each sysfs memory directory is now
considered a memory block that can span multiple memory sections per
memory block. The default size of each memory block is SECTION_SIZE_BITS
to maintain the current behavior of having a single memory section per
memory block (i.e. one sysfs directory per memory section).
For architectures that want to have memory blocks span multiple
memory sections they need only define their own memory_block_size_bytes()
routine.

memory blocks reflected in sysfs.

In ntfs_mft_record_alloc() when mapping the new extent mft record with
map_extent_mft_record() we overwrite @m with the return value and on
error, we then try to use the old @m but that is no longer there as @m
now contains an error code instead so we crash when dereferencing the
error code as if it were a pointer.
The simple fix is to use a temporary variable to store the return value
thus preserving the original @m for later use. This is a backport from
the commercial Tuxera-NTFS driver and is well tested...

This allows a ROM-able zImage to be written to MMC and
for SuperH Mobile ARM to boot directly from the MMCIF
hardware block.
This is achieved by the MaskROM loading the first portion
of the image into MERAM and then jumping to it. This portion
contains loader code which copies the entire image to SDRAM
and jumps to it. From there the zImage boot code proceeds
as normal, uncompressing the image into its final location
and then jumping to it.

* Initialise LED GPIO lines in head-ap4evb.txt instead of mmcif-sh7372.c
as this is considered board-specific.
v3:
Addressed comments made in person by Magnus Damm
* Move mmcif_loader to be earlier in the image and
reduce the number of blocks of boot program loaded by the MaskRom
from 40 to 8 accordingly.
* Move LED GPIO initialisation into mmcif_progress_init
- This leaves the partner jet script unbloated
Other
* inline mmcif_update_progress so it is a static inline in a header file
v4:
* Use htole16() and htole32() in v4rl.c to ensure
that the output is little endian
v5:
Addressed comments by Russell King
* Simplify assembly code
* Jump to code rather than an address <- bug fix
* Use (void __iomem *) as appropriate
Roll in mackerel support
* This was previously a separate patch, only because of the order
in which this code was developed

lh7a40x has only been receiving updates for updates to generic code.
The last involvement from the maintainer according to the git logs was
in 2006. As such, it is a maintainence burden with no benefit.
This gets rid of two defconfigs.

As discussed in a thread on this list titled:
"RFC: short reads on block devices"
this patch adds recommendations for LLDs to set resid
when there might be uncertainty about how much data
has been returned by a device.

Due to a chip bug (errata 50.2.6.3 & 50.3.5.3 in
"AT91SAM9263 Preliminary 6249H-ATARM-27-Jul-09") the contents of mailbox
0 may be send under certain conditions (even if disabled or in rx mode).
The workaround in the errata suggests not to use the mailbox and load it
with an unused identifier.
This patch implements the second part of the workaround. A sysfs entry
"mb0_id" is introduced. While the interface is down it can be used to
configure the can_id of mailbox 0. The default value id 0x7ff.
In order to use an extended can_id add the CAN_EFF_FLAG (0x80000000U)
to the can_id. Example:
- standard id 0x7ff:
echo 0x7ff > /sys/class/net/can0/mb0_id
- extended id 0x1fffffff:
echo 0x9fffffff > /sys/class/net/can0/mb0_id

This new model, named "asus", is identical to the "hp_laptop" model,
except for the location of the internal mic, which is at pin 0x1a.
It is used for Asus K52JU and Lenovo G560.
