The save_fp_context()/restore_fp_context() might sleep on accessing
user stack and therefore might lose FPU ownership in middle of them.
If these function failed due to "in_atomic" test in do_page_fault,
touch the sigcontext area in non-atomic context and retry these
save/restore operation.
This is a replacement of a (broken) fix which was titled "Allow CpU
exception in kernel partially".

Commit 6d6671066a is incomplete and misses
non-r4k CPUs. This patch reverts the commit and fixes in other way.
o Do FCSR checking in caller of restore_fp_context.
o Send SIGFPE if the signal handler set any FPU exception bits.

This patch makes 'struct sigframe' declaration avalaible for all signals
code. It allows signal32 to not have its own declaration.
This patch also removes all ICACHE_REFILLS_WORKAROUND_WAR tests in
structure declaration and hopefully make them more readable.

These functions are quite big and there are no points to make
them inlined. So this patch moves the functions implementation
in signal.c and make them available for others source files
which need them.

This trivial change reduces considerably code size of these
2 functions callers. For instance, here is the figures for
arch/kernel/signal.o objects:
text data bss dec hex filename
11972 0 0 11972 2ec4 arch/mips/kernel/signal.o~old
5380 0 0 5380 1504 arch/mips/kernel/signal.o~new

Rename the 64-bit sc_hi and sc_lo arrays to use the same names
as the 32-bit struct sigcontext (sc_mdhi, sc_hi1, et cetera).

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
