Trying to add memory via add_memory() from within an initcall function
results in
bootmem alloc of 163840 bytes failed!
Kernel panic - not syncing: Out of memory
This is caused by zone_wait_table_init() which uses system_state to decide
if it should use the bootmem allocator or not.
When initcalls are handled the system_state is still SYSTEM_BOOTING but
the bootmem allocator doesn't work anymore. So the allocation will fail.
To fix this use slab_is_available() instead as indicator like we do it
everywhere else.

This occurs when we are scanning the zonelists looking for a ZONE_NORMAL
page. In this system there is only ZONE_DMA and ZONE_NORMAL memory on
node 0, all other nodes are mapped above 4GB physical. Here is a dump
of the zonelists from this system:

When performing a node local allocation we call get_page_from_freelist()
looking for a page. It in turn calls first_zones_zonelist() which returns
a preferred_zone. Where there are no applicable zones this will be NULL.
However we use this unconditionally, leading to this panic.
Where there are no applicable zones there is no possibility of a successful
allocation, so simply fail the allocation.

In 2.6.25, ramdisk devices show up in /proc/partitions, which is a
behaviour change from the old rd.c. Add GENHD_FL_SUPPRESS_PARTITION_INFO,
which was present in rd.c.
All kernels prior to 2.6.25 weren't displaying ramdisks in
/proc/partitions. Since there are many userspace tools using information
from /proc/partitions some of them may now behave incorrectly (I didn't
tested any though). For example before 2.6.25 /proc/partitions was empty
if no block devices like hard disks and such were detected by kernel. Now
all 16 ramdisks are always visible there. Some software may rely on such
information (I mean, on empty /proc/partitions).
There was quite similar situation back in 2004, and ramdisks were excluded
back from displaying. Thats why I called this a regression (maybe a bit
unfortunate). See this patch for info:
http://kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.3-rc2/2.6.3-rc2-mm1/broken-out/nbd-proc-partitions-fix.patch
I also think that someone somewhere (long time ago) excluded ramdisks from
/proc/partitions for good reasons. It is possible that now such new
"feature" is harmless, but I think there are more chances that someone
will say "hey, /proc/partitions has changed, now my software doesn't work"
then "hey where did my new 2.6.25 feature go". nbd devices are also
excluded, maybe for very same (unknown to me) reasons.

When we get any IO error during a recovery (rebuilding a spare), we abort
the recovery and restart it.
For RAID6 (and multi-drive RAID1) it may not be best to restart at the
beginning: when multiple failures can be tolerated, the recovery may be
able to continue and re-doing all that has already been done doesn't make
sense.
We already have the infrastructure to record where a recovery is up to
and restart from there, but it is not being used properly.
This is because:
- We sometimes abort with MD_RECOVERY_ERR rather than just MD_RECOVERY_INTR,
which causes the recovery not be be checkpointed.
- We remove spares and then re-added them which loses important state
information.
The distinction between MD_RECOVERY_ERR and MD_RECOVERY_INTR really isn't
needed. If there is an error, the relevant drive will be marked as
Faulty, and that is enough to ensure correct handling of the error. So we
first remove MD_RECOVERY_ERR, changing some of the uses of it to
MD_RECOVERY_INTR.
Then we cause the attempt to remove a non-faulty device from an array to
fail (unless recovery is impossible as the array is too degraded). Then
when remove_and_add_spares attempts to remove the devices on which
recovery can continue, it will fail, they will remain in place, and
recovery will continue on them as desired.
Issue: If we are halfway through rebuilding a spare and another drive
fails, and a new spare is immediately available, do we want to:
1/ complete the current rebuild, then go back and rebuild the new spare or
2/ restart the rebuild from the start and rebuild both devices in
parallel.
Both options can be argued for. The code currently takes option 2 as
a/ this requires least code change
b/ this results in a minimally-degraded array in minimal time.

In some configurations, a raid6 resync can be limited by CPU speed
(Calculating P and Q and moving data) rather than by device speed. In
these cases there is nothing to be gained byt serialising resync of arrays
that share a device, and doing the resync in parallel can provide benefit.
So add a sysfs tunable to flag an array as being allowed to resync in
parallel with other arrays that use (a different part of) the same device.

be cleared as that might not happen. So explicity test for the bits that

When performing a "recovery" or "check" pass on a RAID1 array, we read
from each device and possible, if there is a difference or a read error,
write back to some devices.
We use the same 'bio' for both read and write, resetting various fields
between the two operations.
We forgot to reset bv_offset and bv_len however. These are often left
unchanged, but in the case where there is an IO error one or two sectors
into a page, they are changed.
This results in correctable errors not being corrected properly. It does
not result in any data corruption.

Fuse allocates a separate bdi for each filesystem, and registers them
in sysfs with "MAJOR:MINOR" of sb->s_dev (st_dev). This works fine for
anon devices normally used by fuse, but can conflict with an already
registered BDI for "fuseblk" filesystems, where sb->s_dev represents a
real block device. In particularl this happens if a non-partitioned
device is being mounted.
Fix by registering with a different name for "fuseblk" filesystems.

IB/mlx4: Fix creation of kernel QP with max number of send s/g entries
IB/mthca: Fix max_sge value returned by query_device
RDMA/cxgb3: Fix uninitialized variable warning in iwch_post_send()
IB/mlx4: Fix uninitialized-var warning in mlx4_ib_post_send()
IB/ipath: Fix UC receive completion opcode for RDMA WRITE with immediate
IB/ipath: Fix printk format for ipath_sdma_status
If a low-level driver returns IB_MAD_RESULT_SUCCESS | IB_MAD_RESULT_CONSUMED,
handle_outgoing_dr_smp() doesn't clean up properly. The fix is to
kfree the local data and break, rather than falling through. This was
observed with the ipath driver, but could happen with any driver.
This fixes <https://bugs.openfabrics.org/show_bug.cgi?id=1027>.

CR4 manipulation is not protected against interrupts and preemption,
but KVM uses smp_function_call to manipulate the X86_CR4_VMXE bit
either from the CPU hotplug code or from the kvm_init call.
We need to protect the CR4 manipulation from both interrupts and
preemption.

This is not a regression from 2.6.25, it's a long standing and hard to
trigger bug.
