While we are at it, param.h and pci.h appear to be candidates for the
same treatment, along with delay.h and auxvec.h.  mutex.h as well...
BTW, we probably can kill arch/um/include/asm/asm-offsets.h - everything
in there is using generated/asm-offsets.h directly.

FWIW, I'd probably kill current.h as well - replace get_current() in
arch/um/kernel/process.c with get_current_pid() (i.e. task_pid_nr(current)),
kill HOST_TASK_PID and switch arch/x86/um/bugs_32.c to use of get_current_pid()
and we can switch to asm-generic/current.h just fine.
