The Vermilion Range Expansion Bus supports four chip selects, each of which
has 64MiB of address space. The 2nd BAR of the Expansion Bus PCI Device
is a 256MiB memory region containing the address spaces for all four of
the chip selects, with start addresses hardcoded on 64MiB boundaries.
This map driver only supports NOR flash on chip select 0. The buswidth
(either 8 bits or 16 bits) is determined by reading the Expansion Bus Timing
and Control Register for Chip Select 0 (EXP_TIMING_CS0).

The CFI probe routine is capable of detecting flash banks consisting of
identical chips mapped to physically discontiguous addresses. (One
common way this can occur is if a flash bank is populated with chips of
less capacity than the hardware was designed to support.) The CFI
point() routine currently ignores any such gaps. This patch fixes
the CFI point() routine so that it truncates any request that would
span a gap.

Make nandsim use GFP_NOFS when allocating memory, because it might
be used by a file-system (e.g. UBIFS2) which means, if we are short
of memory, we may deadlock. Indee, UBIFS is holding a lock, writes
to the media, reaches this place in NANDsim, kmalloc does not find
the requested amount of RAM, calls memory shrinker, which decides
to writeback inodes, calls FS, and it deadlocks on the lock which
is already being held. Below is the UBIFS backtrace which

When building NOR flash support, you have compile-time options for the
bus width and the number of individual chips which are interleaved
together onto that bus. The code to deal with arbitrary geometry is a
bit convoluted, and people want to just configure it for the specific
hardware they have, to avoid the runtime overhead.
Selecting _none_ of the available options doesn't make any sense. You
should have at least one. This makes it build though, since people
persist in trying.

The NUMA layer only supports NUMA policies for the highest zone. When
ZONE_MOVABLE is configured with kernelcore=, the the highest zone becomes
ZONE_MOVABLE. The result is that policies are only applied to allocations
like anonymous pages and page cache allocated from ZONE_MOVABLE when the
zone is used.
This patch applies policies to the two highest zones when the highest zone
is ZONE_MOVABLE. As ZONE_MOVABLE consists of pages from the highest "real"
zone, it's always functionally equivalent.
The patch has been tested on a variety of machines both NUMA and non-NUMA
covering x86, x86_64 and ppc64. No abnormal results were seen in
kernbench, tbench, dbench or hackbench. It passes regression tests from
the numactl package with and without kernelcore= once numactl tests are
patched to wait for vmstat counters to update.
akpm: this is the nasty hack to fix NUMA mempolicies in the presence of
ZONE_MOVABLE and kernelcore= in 2.6.23. Christoph says "For .24 either merge
the mobility or get the other solution that Mel is working on. That solution
would only use a single zonelist per node and filter on the fly. That may
help performance and also help to make memory policies work better."

This is not safe without the rmb() in between. The results of two

The same is true for the "thread_group_empty()" case, __unhash_process()'s

On some platforms (including i386) atomic_read() doesn't provide even the

Due to inconsistent locking in the VFS between calls to lookup and
revalidate deadlock can occur in the automounter.
The inconsistency is that the directory inode mutex is held for both lookup
and revalidate calls when called via lookup_hash whereas it is held only
for lookup during a path walk. Consequently, if the mutex is held during a
call to revalidate autofs4 can't release the mutex to callback the daemon
as it can't know whether it owns the mutex.
This situation happens when a process tries to create a directory within an
automount and a second process also tries to create the same directory
between the lookup and the mkdir. Since the first process has dropped the
mutex for the daemon callback, the second process takes it during
revalidate leading to deadlock between the autofs daemon and the second
process when the daemon tries to create the mount point directory.
After spending quite a bit of time trying to resolve this on more than one
occassion, using rather complex and ulgy approaches, it turns out that just
delaying the hashing of the dentry until the create operation works fine.

The previous patch which limited the number of sectors in a single request
to a COWed device was correct in concept, but the limit was implemented in
the wrong place.
By putting it in ubd_add, it covered the cases where the COWing was
specified on the command line. However, when the command line only has the
COW file specified, the fact that it's a COW file isn't known until it's
opened, so the limit is missed in these cases.
This patch moves the sector limit from ubd_add to ubd_open_dev.

With this patch any thread can dequeue its own private signals via signalfd,
even if it was created by another sub-thread.
To do so, we pass "current" to dequeue_signal() if the caller is from the same
thread group. This also fixes the scheduling of posix timers broken by the
previous patch.
If the caller doesn't belong to this thread group, we can't handle __SI_TIMER
case properly anyway. Perhaps we should forbid the cross-process signalfd usage

When suspend is ever implemented for pmu68k it really should follow the
generic pm_ops concept and not mirror the platform-specific /dev/pmu
device with ioctls on it. Hence, this patch removes the unused code there;
should the implementers need it they can look at via-pmu.c and/or the
history of the file.
