d2ba8b211b x86: Fix assert syntax in vmlinux.lds.S
Older versions of binutils did not accept the naked "ASSERT" syntax;
it is considered an expression whose value needs to be assigned to
something.

6a7bbd57ed x86: Make 64-bit efi_ioremap use ioremap on MMIO regions
Booting current 64-bit x86 kernels on the latest Apple MacBook
(MacBook5,2) via EFI gives the following warning:

This happens because the 64-bit version of efi_ioremap calls
init_memory_mapping for all addresses, regardless of whether they are
RAM or MMIO.  The EFI tables on this machine ask for runtime access to
some MMIO regions:

[    0.000000] EFI: mem195: type=11, attr=0x8000000000000000, range=[0x0000000093400000-0x0000000093401000) (0MB)

[    0.000000] EFI: mem198: type=11, attr=0x8000000000000000, range=[0x00000000ffc80000-0x00000000ffca4000) (0MB)

This arranges to pass the EFI memory type through to efi_ioremap, and
makes efi_ioremap use ioremap rather than init_memory_mapping if the
type is EFI_MEMORY_MAPPED_IO.  With this, the above warning goes away.

6c6c51e4cc x86: Add quirk to make Apple MacBook5,2 use reboot=pci
The latest Apple MacBook (MacBook5,2) doesn't reboot successfully
under Linux; neither the EFI reboot method nor the default method
using the keyboard controller works (the system just hangs and doesn't
reset).  However, the method using the "PCI reset register" at 0xcf9
does work.

This adds a quirk to detect this machine via DMI and force the
reboot_type to BOOT_CF9.  With this it reboots successfully without
requiring a command-line option.  Note that the EFI code forces
reboot_type to BOOT_EFI when the machine is booted via EFI, but this
overrides that since the core_initcall runs after the EFI
initialization code.

371842448c cfg80211: fix regression on beacon world roaming feature
A regression was added through patch a4ed90d6:

"cfg80211: respect API on orig_flags on channel for beacon hint"

We did indeed respect _orig flags but the intention was not clearly
stated in the commit log. This patch fixes firmware issues picked
up by iwlwifi when we lift passive scan of beaconing restrictions
on channels its EEPROM has been configured to always enable.

By doing so though we also disallowed beacon hints on devices
registering their wiphy with custom world regulatory domains
enabled, this happens to be currently ath5k, ath9k and ar9170.
The passive scan and beacon restrictions on those devices would
never be lifted even if we did find a beacon and the hardware did
support such enhancements when world roaming.

Since Johannes indicates iwlwifi firmware cannot be changed to
allow beacon hinting we set up a flag now to specifically allow
drivers to disable beacon hints for devices which cannot use them.

We enable the flag on iwlwifi to disable beacon hints and by default
enable it for all other drivers. It should be noted beacon hints lift
passive scan flags and beacon restrictions when we receive a beacon from
an AP on any 5 GHz non-DFS channels, and channels 12-14 on the 2.4 GHz
band. We don't bother with channels 1-11 as those channels are allowed
world wide.

This should fix world roaming for ath5k, ath9k and ar9170, thereby
improving scan time when we receive the first beacon from any AP,
and also enabling beaconing operation (AP/IBSS/Mesh) on cards which
would otherwise not be allowed to do so. Drivers not using custom
regulatory stuff (wiphy_apply_custom_regulatory()) were not affected
by this as the orig_flags for the channels would have been cleared
upon wiphy registration.

I tested this with a world roaming ath5k card.

The default completion timeout values for 82598 should be in the
range of 50us to 50ms, however the hardware default for these
parts is 500us to 1ms which is less than the 10ms recommended by
the pcie spec. To address this we need to increase the value to
either 10ms to 250ms for capability version 1 configuration, or
16ms to 55ms for version 2.

rfcomm tty may be used before rfcomm_tty_driver initilized,
The problem is that now socket layer init before tty layer, if userspace
program do socket callback right here then oops will happen.

reporting in:
http://marc.info/?l=linux-bluetooth&m=124404919324542&w=2

make 3 changes:
1. remove #ifdef in rfcomm/core.c,
make it blank function when rfcomm tty not selected in rfcomm.h

2. tune the rfcomm_init error patch to ensure
tty driver initilized before rfcomm socket usage.

3. remove __exit for rfcomm_cleanup_sockets
because above change need call it in a __init function.

8523acfe40 x86: Fix CPA memtype reserving in the set_pages_array*() cases
The code was incorrectly reserving memtypes using the page
virtual address instead of the physical address. Furthermore,
the code was not ignoring highmem pages as it ought to.

( upstream does not pass in highmem pages yet - but upcoming
  graphics code will do it and there's no reason to not handle
  this properly in the CPA APIs.)

0ca71737fe MIPS: Simplify and correct interrupt handling for MSP4200
The current interrupt handling code for the MSP4200 always masks an
interrupt before acknowledging it.  This is not required, as that will be
handled by the level interrupt handler.  This change simplifies the MSP4200
code to remove the masking in the ack routine, and makes sure that the
minimum required operation is performed for masking and acking, rather
than always both masking and acking the interrupt.

6577890fd6 MIPS: MSPxxxx: define MIPS34K_MISSED_ITLB_WAR for other PMC-Sierra SoC
Trying to build a PMC-Sierra MSP4200 VoIP gateway defconfig will not work
since MIPS34K_MISSED_ITLB_WAR is not defined for all boards supported
within pmc-serria/msp71xx. This patch defines MIPS34K_MISSED_ITLB_WAR to
prevent such build failures:

  SYMLINK include/asm -> include/asm-mips

Trying to build MSP4200 VoIP defconfig also fails on msp_irq_slp.c with a

Passed that, we will also miss a comma when calling

0e66fff883 MIPS: Fix loading of modules with unresolved weak symbols
Loading of modules with unresolved weak symbols fails on MIPS
since '88173507e4fc1e7ecd111b0565e8cba0cb7dae6d'.

Modules: handle symbols that have a zero value

The module subsystem cannot handle symbols that are zero.  If symbols
are present that have a zero value then the module resolver prints out a
message that these symbols are unresolved.

We have to use IS_ERR_VALUE() to check that a symbol has been resolved
or not.

484889fc85 MIPS: Avoid clobbering struct pt_regs in kthreads
The resume() implementation octeon_switch.S examines the saved cp0_status
register.  We were clobbering the entire pt_regs structure in kernel
threads leading to random crashes.

When switching away from a kernel thread, the saved cp0_status is examined
and if bit 30 is set it is cleared and the CP2 state saved into the pt_regs
structure.  Since the kernel thread stack overlaid the pt_regs structure
this resulted in a corrupt stack.  When the kthread with the corrupt stack
was resumed, it could crash if it used any of the data in the stack that was
clobbered.

We fix it by moving the kernel thread stack down so it doesn't overlay
pt_regs.
