Hi!

The hangcheck timer seems cannot be compiled on Alphas:

  gcc -Wp,-MD,drivers/char/.hangcheck-timer.o.d -D__KERNEL__ -Iinclude -Wall -Wstrict-prototypes -Wno-trigraphs -O2 -fno-strict-aliasing -fno-common -pipe -mno-fp-regs -ffixed-8 -msmall-data -mcpu=ev4 -Wa,-mev6 -fomit-frame-pointer -nostdinc -iwithprefix include -DMODULE -DKBUILD_BASENAME=hangcheck_timer -DKBUILD_MODNAME=hangcheck_timer -c -o drivers/char/hangcheck-timer.o drivers/char/hangcheck-timer.c
drivers/char/hangcheck-timer.c: In function `hangcheck_init':
drivers/char/hangcheck-timer.c:112: `current_cpu_data' undeclared (first use in this function)
drivers/char/hangcheck-timer.c:112: (Each undeclared identifier is reported only once
drivers/char/hangcheck-timer.c:112: for each function it appears in.)
make[3]: *** [drivers/char/hangcheck-timer.o] Error 1
make[2]: *** [drivers/char] Error 2
make[1]: *** [drivers] Error 2
make: *** [modules] Error 2

This is because current_cpu_data doesn't (currently) exist on alpha.

Indeed.  Hangcheck is incorrectly assuming x86 datastructures.

Anyway, the driver as written isn't going to be useful on alpha
since the 32-bit TSC rolls over every 8 seconds.
