Add ability to expend the hardware trace buffer via a configurable
software buffer - so you can have lots of history when a crash occurs.
The interesting way we do printk in the traps.c confusese the checking
script

Fix CCLK and SCLK checks, combine all arch checks into one file
for maintance. Checkins that remove more lines than they add are always
good.

revise anomaly handling by basing things on the compiler not the kconfig defines,
so the header is stable and usable outside of the kernel. This also allows us to
move some code from preprocessing to compiling (gcc culls dead code)
which should help with code quality (readability, catch minor bugs, etc...).

can be handled when memory protection is enabled.

setup aliases for some core Core A MMRs to ease porting in cases
where common code would actually want Core A (or Core B MMR is reserved)

Add function helper, fb_is_primary_device(). Given struct fb_info, it will
return a nonzero value if the device is the primary display.
Currently, only the i386 is supported where the function checks for the
IORESOURCE_ROM_SHADOW flag.
