4b4554f6d5 score: it's "VERIFY_WRITE", not "VERFITY_WRITE"... 
... and the only reason it worked is that access_ok() discards the
first argument before parser even gets a chance of looking at it.
Still, no point keeping that typo.

9a7513cfa2 frv: switch to use of fixup_exception() 
Massage frv search_exception_table() to
	a) taking pt_regs pointer as explicit argument
	b) updating ->pc on success
Simplifies callers a bit and allows to convert to generic extable.h,
while we are at it.

e5c1540030 avr32: switch to RAW_COPY_USER 
This one needs profiling; use of asm variant of access_ok() might have
been performance-critical.  Now copy_{to,from}_user() are using the
C variant.  I doubt that it's going to have visible effects, but
that needs to be experimentally verified.

f14d6b4f52 alpha: don't bother with __access_ok() in traps.c 
we want to check that address is below TASK_SIZE; sure,
__access_ok(addr, 0, USER_DS) will do that, but it's more straightforward
to just spell it out and that way we can get rid of the damn 'segment'
argument of __access_ok().
