In commit c441d4a54c ("MIPS: mm: Only build one microassembler that
is suitable"), the Makefile at arch/mips/mm was rewritten to only
build the "right" microassembler file, depending on whether
CONFIG_CPU_MICROMIPS is set or not.
In the files, however, there are still preprocessor definitions
depending on CONFIG_CPU_MICROMIPS. The #ifdef around them can now
never evaluate to true, so let's remove them altogether.
This inconsistency was found using the undertaker-checkpatch tool.

Since commit 8e5cfb55d3 (Btrfs: Make raid_map array be inlined in
btrfs_bio structure), the raid map array is allocated along with the
btrfs bio in alloc_btrfs_bio. The calculation used to decide how much
we need to allocate was using the wrong parameter passed into the
allocation function.
The passed in real_stripes will be zero if a target replace operation
is not currently running. We want to use total_stripes instead.

The current code uses bits 0-6 of the sys_cpupll register to calculate
core clock speed. However this is only valid on Au1300, on all earlier
models the hardware only uses bits 0-5 to generate core clock.
This fixes clock calculation on the MTX1 (Au1500), where bit 6 of cpupll
is set as well, which ultimately lead the code to calculate a bogus cpu
core clock and also uart base clock down the line.

There doesn't seem to be any valid reason to allocate the pages array
with the same flags as the buffer itself. Doing so can eventually lead
to the following safeguard in mm/slab.c's cache_grow() to be hit:
if (unlikely(flags & GFP_SLAB_BUG_MASK)) {
pr_emerg("gfp: %un", flags & GFP_SLAB_BUG_MASK);
BUG();
}
This happens when buffers are allocated with __GFP_DMA32 or
__GFP_HIGHMEM.
Fix this by allocating the pages array with GFP_KERNEL to follow what is
done elsewhere in this file. Using GFP_KERNEL in __iommu_alloc_buffer()
is safe because atomic allocations are handled by __iommu_alloc_atomic().

Code that does this:
if (!(d_unhashed(tmp) && tmp->d_inode)) {
...
simple_unlink(parent->d_inode, tmp);
}
is broken because:
!(d_unhashed(tmp) && tmp->d_inode)
is equivalent to:
!d_unhashed(tmp) || !tmp->d_inode
so it is possible to get into simple_unlink() with tmp->d_inode == NULL.
simple_unlink(), however, assumes tmp->d_inode cannot be NULL.
I think that what was meant is this:
!d_unhashed(tmp) && tmp->d_inode
and that the logical-not operator or the final close-bracket was misplaced.

We don't really need to recalculate the effective rate of a clock when a
per-user clock is removed, if the constraints of the later aren't
limiting the requested rate.
This was causing problems with clocks that never had a rate set before,
as rate_req would be zero. Though this could be considered a bug in the
implementation of those clocks, this should be checked somewhere else.
