MIPS: Fix execution hazard during watchpoint register probe
Writing a value to a WatchLo* register creates an execution hazard, so
if its value is then read before that hazard is cleared then said value
may be invalid. The mips_probe_watch_registers function must therefore
clear the execution hazard between setting the match bits in a WatchLo*
register & reading the register back in order to check which are set.
This fixes intermittent incorrect watchpoint register probing on some
MIPS cores such as interAptiv & proAptiv.

size, this 'extra' memory may contain data passed from the bootloader
to the kernel itself, which if clobbered makes the kernel crash in
various ways.

assigned to the kernel.

The problem is that we're ending up in __rpc_lookup_create_exclusive

has shown that when we hit this, the d_ops are already set to
simple_dentry_operations.
I believe that what's happening is that during a mount, idmapd is racing
in and doing a lookup of /var/lib/nfs/rpc_pipefs/nfs/clnt???/idmap.
Before that dentry reference is released, the kernel races in to create
that file and finds the new negative dentry, which already has the
d_op set.
This patch just avoids setting the d_op if it's already set.
simple_dentry_operations and rpc_dentry_operations are functionally
equivalent so it shouldn't matter which one it's set to.

MIPS: Delete __cpuinit/__CPUINIT usage from MIPS code
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.

lib: Move fonts from drivers/video/console/ to lib/fonts/

support code selection logic").
Hence move the fonts and their support logic from drivers/video/console/ to
its own library directory lib/fonts/.
This also allows to limit processing of drivers/video/console/Makefile to
CONFIG_VT=y again.
console/font: Refactor font support code selection logic
The current Makefile rules to build font support are messy and buggy.
Replace them by Kconfig rules:
- Introduce CONFIG_FONT_SUPPORT, which controls the building of all font
code,
- Select CONFIG_FONT_SUPPORT for all drivers that use fonts,
- Select CONFIG_FONT_8x16 for all drivers that default to the VGA8x16
font,
- Drop the bogus console dependency for CONFIG_VIDEO_VIVI,
- Always process drivers/video/console/Makefile, as some drivers need
fonts even if CONFIG_VT is not set.
This fixes (if CONFIG_SOLO6X10=y and there are no built-in console
drivers):
