pbrook 0b1bcb00fb MIPS signal handling fixes. 
Also fixes a register corruption bug in do_sigreturn. When "returning"
from sigreturn we are actually restoring the virtual cpu state from the
signal frame.  This is actually surprisingly hard to observe in practice.

Typically an thread be blocked in a FUTEX_WAIT call when the signal arrives,
so the effect is a spurious syscall success and the introduction of a
subtle race condition.

On x86/arm a syscall modifies a single word sized register, so
do_sigreturn can just return that value.  On MIPS a syscall clobbers
multiple registers, so we need additional smarts.  My solution is to
invent a magic errno value that means "don't touch CPU state".

pbrook f753ff1638 Register a single area for vga bios and option roms 
Those guys are not different in nature. They're all roms,
not blessed with the graces of being written to. So there's
not need to issue multiple requests to memory registration areas:
just treat them as brothers, and put them all in the same
region.

It also has the nice side effect of improving the loading code
a little bit. Besides some of the ugliness going away, we're now
avoiding phys_ram_base dependencies in option rom code.

pbrook 9a3ea65402 When -icount is used and a TB is recompiled due to an IO access 
shortly after an IRQ has been raised, env->exception_index will still be set 
to EXCP_IRQ when cpu_io_recompile calls cpu_resume_from_signal.
This causes qemu to repeat the IRQ trap, with disasterous consequences.

I suspect this "works" most of the time because linux tends to drop back to
svc mode before doing actual IRQ processing, and be fairly
tolerant of spurious IRQ traps.

pbrook 49918a752b * Use function pointers for symbol lookup (currently for elf32 and elf64, 
could be expanded).  This also fixes the bug with mips elf64 symbols
  in current Qemu trunk.

* Use quicksort and binary search for symbol lookup.

* Remove unneeded entries from symbol table.  This reduced a typical table
  size (linux mips kernel) from 1764487 to 11656 entries.

pbrook 558fa8361b My core2duo patch introduced a vague statement of "missing features" in 
the CPUID specification. This patch addresses this by specifying exactly 
what is missing.
While going along the missing CPUID entries I also stumbled across 
invalid and missing CPUID #defines while comparing them to the Intel 
Documentation. This patch also addresses these. I found them too minor 
to split them up in a separate patch.

Furthermore I looked through CPUID functions > 5 and realized that it 
should be safe to bump the level to 10. I tried booting Linux with that 
and it worked fine.
