2017-03-28score: it's "VERIFY_WRITE", not "VERFITY_WRITE"...Al Viro
... 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. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

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. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

we want to get rid of it; unfortunately, it's tangled as hell, so it'll take many steps, more's the pity. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2017-03-28avr32: switch to RAW_COPY_USERAl Viro
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. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2017-03-28alpha: don't bother with __access_ok() in traps.cAl Viro
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(). Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
