Replace the ->check_acl method with a ->get_acl method that simply reads an
ACL from disk after having a cache miss. This means we can replace the ACL
checking boilerplate code with a single implementation in namei.c.

Always set up a negative ACL cache entry if the inode can't have ACLs.

If we do not want to use ACLs we at least need to perform normal Unix
permission checks. From the comment I'm not quite sure that's what
is intended, but if 0p wants to do permission checks entirely on the
server it needs to do so in ->permission, not in ->check_acl.

This moves logic for checking the cached ACL values from low-level
filesystems into generic code. The end result is a streamlined ACL
check that doesn't need to load the inode->i_op->check_acl pointer at
all for the common cached case.
The filesystems also don't need to check for a non-blocking RCU walk
case in their acl_check() functions, because that is all handled at a
VFS layer.

commit fec11dd9a0109fe52fd631e5c510778d6cbff6cc caused
a regression when we have already mounted //server/share/a
and want to mount //server/share/a/b.
The problem is that lookup_one_len calls __lookup_hash
with nd pointer as NULL. Then __lookup_hash calls
do_revalidate in the case when dentry exists and we end
up with NULL pointer deference in cifs_d_revalidate:
if (nd->flags & LOOKUP_RCU)
return -ECHILD;
Fix this by checking nd for NULL.

The fsync prototype change commit 02c24a82187d accidentally overwrote
the ssize_t return value of xfs_file_aio_write with 0 for SYNC type
writes. Fix this by checking if an error occured when calling
xfs_file_fsync and only change the return value in this case.
In addition xfs_file_fsync actually returns a normal negative error, so
fix this, too.

When CONFIG_PCI is not enabled, CONFIG_EISA=y, and CONFIG_GENERIC_IOMAP=y,
drivers/net/3c59x.c build fails due to a recent small change to
<asm-generic/iomap.h> that surrounds pci_iomap() and pci_iounmap() with
#ifdef CONFIG_PCI/#endif.
Since that patch to iomap.h looks correct, add stubs for pci_iomap() and
pci_iounmap() with CONFIG_PCI is not enabled to fix the build errors.

Enable cpu_has_clo_clz only when CONFIG_CPU_MIPS32 or CONFIG_CPU_MIPS64
is selected. This will optimize fls() and __fls() to use CLZ insn, and
eventually ffs() and __ffs() as well.
Malta and MIPSSim are development platforms, and need to take care of
various processor configurations, release rivisions and so on, even
across different MIPS ISAs. For such platforms we have to be careful,
for instance, with turning on cpu_has_mips{32,64}r[12] features.
As for CLZ, all MIPS32/64 processors support it, regardless of release
revisions.

address of 0xfffe_0000, this can consume up to 4 pages (1 page per 4MB)

On processors with deep write buffers, it is likely that many cycles
will pass between a CACHE instruction and the time the data actually
gets written out to DRAM. Add a SYNC instruction to ensure that the
buffers get emptied before the flush functions return.
Actual problem seen in the wild:
1) dma_alloc_coherent() allocates cached memory
2) memset() is called to clear the new pages
3) dma_cache_wback_inv() is called to flush the zero data out to memory
4) dma_alloc_coherent() returns an uncached (kseg1) pointer to the
freshly allocated pages
5) Caller writes data through the kseg1 pointer
6) Buffered writeback data finally gets flushed out to DRAM
7) Part of caller's data is inexplicably zeroed out
This patch adds SYNC between steps 3 and 4, which fixed the problem.

pfn_valid() compares the PFN to max_mapnr:
__pfn >= min_low_pfn && __pfn < max_mapnr;
On HIGHMEM kernels, highend_pfn is used to set the value of max_mapnr.
Unfortunately, highend_pfn is left at zero if the system does not
actually have enough RAM to reach into the HIGHMEM range. This causes
pfn_valid() to always return false, and when debug checks are enabled
the kernel will fail catastrophically:
Memory: 22432k/32768k available (2249k kernel code, 10336k reserved, 653k data, 1352k init, 0k highmem)
NR_IRQS:128
kfree_debugcheck: out of range ptr 81c02900h.
Kernel bug detected[#1]:
Cpu 0
$ 0 : 00000000 10008400 00000034 00000000
$ 4 : 8003e160 802a0000 8003e160 00000000
$ 8 : 00000000 0000003e 00000747 00000747
...
On such a configuration, max_low_pfn should be used to set max_mapnr.
This was seen on 2.6.34.

This patch introduced topdown mmap support in user process address
space allocation policy.
Recently, we ran some large applications that use mmap heavily and
lead to OOM due to inflexible mmap allocation policy on MIPS32.
Since most other major archs supported it for years, it is reasonable
to follow the trend and reduce the pain of porting applications.
Due to cache aliasing concern, arch_get_unmapped_area_topdown() and
other helper functions are implemented in arch/mips/kernel/syscall.c.
