When legacy signal handling is disabled, the
arch/microblaze/kernel/signal.c implementation can
be much simpler, as most of it is handled generically
from kernel/signal.c.
This is also a prerequisite for using the generic
asm/unistd.h, which does not provide __NR_sigreturn,
because this macro is referenced by the current signal.c
implementation.

Yinghai noticed that i defined BIOS_BUG_MSG but added no
usage for it. The usage is to clean up this turd in generic.c:
printk(KERN_WARNING "WARNING: BIOS bug: VAR MTRR %d "
"contains strange UC entry under 1M, check "
"with your system vendor!\n", i);
Breaking printk lines in the middle looks ugly, is hard to read
and breaks 'git grep'. Use the BIOS_BUG_MSG instead.
Also complete the moving of structure definitions and variables
to the top of the file.

This patch adds cpuidle support for SuperH Mobile.
The sleep mode selected by cpuidle is compared with
the mode selected by the hwblk sleep code and the
best allowed mode is entered.
At this point "Sleep mode" and "Sleep mode + SF" are
supported. This code can easily be extended to support
"Software suspend mode", but the assembly code must
first be updated to avoid loosing interrupts.
Also, update the code to only copy the assembly snippet
into internal memory once at bootup.

This patch is the hwblk base implementation, containing
structures and shared functions dealing with hardware blocks.
A each processor model should provide a list of hwblks and
describe which module stop bit that is associated with each
hwblck and how the hwblks are grouped together into areas.
The shared code keeps track of the usage count for each
hwblk and the areas. Fallback implementations for processor
specific code are also kept as weak symbols.
The clock framework, the runtime pm code and cpuidle will
all tie into this hwblk implementation.
