commit 77238e76b9156d28d86c1e31c00ed2960df0e4de upstream.
It seems that this is a typo error and the proper bit masking is
"RT | RS" instead of "RS | RS".
This issue was detected with the help of Coccinelle.

In commit c441d4a54c6e ("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.

None of these files are actually using any __init type directives
and hence don't need to include <linux/init.h>. Most are just a
left over from __devinit and __cpuinit removal, or simply due to
code getting copied from one driver to the next.

commit 3747069b25e419f6b51395f48127e9812abc3596 upstream.
The __cpuinit type of throwaway sections might have made sense
some time ago when RAM was more constrained, but now the savings
do not offset the cost and complications. For example, the fix in
commit 5e427ec2d0 ("x86: Fix bit corruption at CPU resume time")
is a good example of the nasty type of bugs that can be created
with improper use of the various __init prefixes.
After a discussion on LKML[1] it was decided that cpuinit should go
the way of devinit and be phased out. Once all the users are gone,
we can then finally remove the macros themselves from linux/init.h.
Note that some harmless section mismatch warnings may result, since
notify_cpu_starting() and cpu_up() are arch independent (kernel/cpu.c)
and are flagged as __cpuinit -- so if we remove the __cpuinit from
the arch specific callers, we will also get section mismatch warnings.
As an intermediate step, we intend to turn the linux/init.h cpuinit
related content into no-ops as early as possible, since that will get
rid of these warnings. In any case, they are temporary and harmless.
Here, we remove all the MIPS __cpuinit from C code and __CPUINIT
from asm files. MIPS is interesting in this respect, because there
are also uasm users hiding behind their own renamed versions of the
__cpuinit macros.

Jump or branch target addresses have the first bit set. The
original mask did not take this into account and will cause
a field overflow warning for the target address when a jump
immediate instruction is built.

Add new file 'uasm-micromips.c' that allows the micro assembler
to generate microMIPS ISA code. It can be included in the kernel
alongside the classic ISA as long as the platform supports the
microMIPS ISA.
