The _TIF_WORK_MASK definition was removed in the clean up of MMU and
non-MMU arch/m68k/include/asm/thread_info*.h files (this was commit
cddafa3500fde4a07e5bf899ec97a04069f8f7ce, "merge MMU and non-MMU
thread_info.h").
It didn't get cleaned out of the entry.S code for the 68328 and 68360
based platforms. And it was replaced by a hard coded constant mask for
coldfire platforms. There is currently no need to mask any of these bits,
so fix all uses (and former uses) to check for any non-zero value.

In prepare_kernel_cred() since 2.6.29, put_cred(new) is called without
assigning new->usage when security_prepare_creds() returned an error. As a
result, memory for new and refcount for new->{user,group_info,tgcred} are
leaked because put_cred(new) won't call __put_cred() unless old->usage == 1.
Fix these leaks by assigning new->usage (and new->subscribers which was added
in 2.6.32) before calling security_prepare_creds().

In cred_alloc_blank() since 2.6.32, abort_creds(new) is called with
new->security == NULL and new->magic == 0 when security_cred_alloc_blank()
returns an error. As a result, BUG() will be triggered if SELinux is enabled
or CONFIG_DEBUG_CREDENTIALS=y.
If CONFIG_DEBUG_CREDENTIALS=y, BUG() is called from __invalid_creds() because
cred->magic == 0. Failing that, BUG() is called from selinux_cred_free()
because selinux_cred_free() is not expecting cred->security == NULL. This does
not affect smack_cred_free(), tomoyo_cred_free() or apparmor_cred_free().
Fix these bugs by
(1) Set new->magic before calling security_cred_alloc_blank().
(2) Handle null cred->security in creds_are_invalid() and selinux_cred_free().

The AACI TRM requires the MAINCR enable bit to be held zero for two
bitclk cycles plus three apb_pclk cycles. Use a delay of 1us to
ensure this.
Ensure that writes to MAINCR to change the addressed codec only happen
when required, and that they take effect in a similar manner to the
above, otherwise we seem to occasionally have stuck slot busy bits.

We reserve lowmem for the things that need it, like the ACPI
wakeup code, way early to guarantee availability. This happens
before we set up the proper pagetables, so set_memory_x() has no
effect.
Until we have a better solution, use an initcall to mark the
wakeup code executable.

Spinlocks on shared processor partitions use H_YIELD to notify the
hypervisor we are waiting on another virtual CPU. Unfortunately this means
the hcall tracepoints can recurse.
The patch below adds a percpu depth and checks it on both the entry and
exit hcall tracepoints.

When converting to the new cpumask code I screwed up:
- if (cpu_isset(cpu, numa_cpumask_lookup_table[node])) {
- cpu_clear(cpu, numa_cpumask_lookup_table[node]);
+ if (cpumask_test_cpu(cpu, node_to_cpumask_map[node])) {
+ cpumask_set_cpu(cpu, node_to_cpumask_map[node]);
This was introduced in commit 25863de07af9 (powerpc/cpumask: Convert NUMA code

VPHN supports up to 8 distance fields but the number of entries in
ibm,associativity-reference-points signifies how many are in use.
Don't look at all the VPHN counts, only distance_ref_points_depth
worth.
Since we already cap our distance metrics at MAX_DISTANCE_REF_POINTS,
use that to size the VPHN arrays and add a BUILD_BUG_ON to avoid it growing
larger than the VPHN maximum of 8.

Some of those functions try to adjust the CPU features, for example
to remove NAP support on some revisions. However, they seem to use
r5 as an index into the CPU table entry, which might have been right
a long time ago but no longer is. r4 is the right register to use.
This probably caused some off behaviours on some PowerMac variants
using 750cx or 7455 processor revisions.

When calling setup_cpu() on 64-bit, we pass a pointer to the
cputable entry we have found. This used to be fine when cur_cpu_spec
was a pointer to that entry, but nowadays, we copy the entry into
a separate variable, and we do so before we call the setup_cpu()
callback. That means that any attempt by that callback at patching
the CPU table entry (to adjust CPU features for example) will patch
the wrong table.

This has been resulting in a BUT_ON(ret) after btrfs_reserve_extent in
btrfs_cow_file_range. The reason is we don't actually calculate the bytes_super
for a block group until we go to cache it, which means that the space_info can
hand out reservations for space that it doesn't actually have, and we can run
out of data space. This is also a problem if you are using space caching since
we don't ever calculate bytes_super for the block groups. So instead everytime
we read a block group call exclude_super_stripes, which calculates the
bytes_super for the block group so it can be left out of the space_info. Then
whenever caching completes we just call free_excluded_extents so that the super
excluded extents are freed up. Also if we are unmounting and we hit any block
groups that haven't been cached we still need to call free_excluded_extents to
make sure things are cleaned up properly. Thanks,

When we're cleaning up the tree log we need to be able to remove free space from
the block group. The problem is if that free space spans bitmaps we would not
find the space since we're looking for too many bytes. So make sure the amount
of bytes we search for is limited to either the number of bytes we want, or the
number of bytes left in the bitmap. This was tested by a user who was hitting
the BUG() after search_bitmap. With this patch he can now mount his fs.
