* Do not include unnecessary headers.
* Do not mention time.README.
* Do not mention mips_timer_ack.
* Make clocksource_mips static. It is now dedicated to c0_timer.
* Initialize clocksource_mips.read statically.
* Remove null_hpt_read.
* Remove an argument of plat_timer_setup. It is just a placeholder.

R7780RP can't do byte-sized accesses to CF, so needs to do word
sized access with low-byte masking. This same problem exists
on older versions of the R2D, with the same workaround having
been implemented in 43f4b8c7578b928892b6f01d374346ae14e5eb70
there. Follow that change for the highlander boards.
This does not impact R7780MP or SH7785 based Highlander modules.
If you're unfortunate enough to be stuck with an R7780RP, this
patch is for you!

It's assumed that .eh_frame is terminated with 4-byte 0 in shared
libraries and executable. It seems to be the case for VDSOs too.
Without this terminator, I saw failures when unwinding from VDSO,
though I don't know how other architectures handle this issue.
For the normal libs, crtendS.o gives this terminator. We can use
such terminating objects. Or we can add a 4-byte 0 with modifying
the linker script like as the patch below.

While using separate IRQ stacks can cut down on stack consumption,
many users can also use 4k stacks directly without the additional
need of separate stacks for soft and hardirqs.
With this split, we support the same rationale for 4KSTACKS as
m68knommu, with the IRQSTACKS abstraction as per ppc64.

movca.l is restricted to SH-4 and up only, though compilers that

mmu_mapin_ram() loops over total_lowmem to setup page tables. However, if
total_lowmem is less that 16M, the subtraction rolls over and results in
a number just under 4G (because total_lowmem is an unsigned value).
This patch rejigs the loop from countup to countdown to eliminate the
bug.
Special thanks to Magnus Hjorth who wrote the original patch to fix this
bug. This patch improves on his by making the loop code simpler (which
also eliminates the possibility of another rollover at the high end)
and also applies the change to arch/powerpc.

The 44x family has an interesting "feature" which is a virtually
tagged instruction cache (yuck !). So far, we haven't dealt with
it properly, which means we've been mostly lucky or people didn't
report the problems, unless people have been running custom patches
in their distro...
This is an attempt at fixing it properly. I chose to do it by
setting a global flag whenever we change a PTE that was previously
marked executable, and flush the entire instruction cache upon
return to user space when that happens.
This is a bit heavy handed, but it's hard to do more fine grained
flushes as the icbi instruction, on those processor, for some very
strange reasons (since the cache is virtually mapped) still requires
a valid TLB entry for reading in the target address space, which
isn't something I want to deal with.

On 4xx CPUs, the current implementation of flush_tlb_page() uses
a low level _tlbie() assembly function that only works for the
current PID. Thus, invalidations caused by, for example, a COW
fault triggered by get_user_pages() from a different context will
not work properly, causing among other things, gdb breakpoints
to fail.
This patch adds a "pid" argument to _tlbie() on 4xx processors,
and uses it to flush entries in the right context. FSL BookE
also gets the argument but it seems they don't need it (their
tlbivax form ignores the PID when invalidating according to the
document I have).

PowerPC 440EP(x) 440GR(x) processors have the same PVR values, since
they have identical cores. However, FPU is not supported on GR(x) and
enabling APU instruction broadcast in the CCR0 register (to enable FPU)
may cause unpredictable results. There's no safe way to detect FPU
support at runtime. This patch provides a workarund for the issue.
We use a POWER6 "logical PVR approach". First, we identify all EP(x)
and GR(x) processors as GR(x) ones (which is safe). Then we check
the device tree cpu path. If we have a EP(x) processor entry,
we call identify_cpu again with PVR | 0x8. This bit is always 0
in the real PVR. This way we enable FPU only for 440EP(x).

When CONFIG_BUG is turned off, the standard trick of:
switch (x) {
case X:
...
case Y:
...
default:
BUG();
};
to mark impossible cases does not work because BUG() evalutes
to nothing and thus GCC just sees a fallthrough code path.
Add an explicit KERN_ERR log message and a do_exit() to trap
this case.

The I-cache disable is an errata workaround, so the solution is to
disable FIQs across the section with the I-cache disabled.

CPU_HAS_SR_RB is selected by both CPU_SH3 and CPU_SH4, so having a
dependency and default y on those additionally doesn't make much sense.
The select also has to be special cased for CPUs that don't support
this.
This is also something that has been abused too much as a result
of being user-visible, hence the addition of the select in the first
place. So just kill the user-visibility entirely while we're at it.
