sh: Fix up TIF_NOTIFY_RESUME sans TIF_SIGPENDING handling.

2012-09-18T08:04:37+00:00

As Al notes, we missed a TIF_NOTIFY_RESUME check which caused any
handlers without TIF_SIGPENDING also set to skip the notification:

	Looks like while it is in the relevant masks *and* checked in
	do_notify_resume() both on 32bit and 64bit variants since commit
	ab99c733ae73cce31f2a2434f7099564e5a73d95 ("sh: Make syscall tracer
	use tracehook notifiers, add TIF_NOTIFY_RESUME.") they are
	actually *not* reached without simulataneous SIGPENDING, since
	the actual glue in the callers had not been updated back then and
	still checks for _TIF_SIGPENDING alone when deciding whether to
	hit do_notify_resume() or not.

sh: use the new generic strnlen_user() function

2012-06-13T01:28:37+00:00

This discards both the _32 and _64 versions in favour of the consolidated
generic one.

sh: switch to generic strncpy_from_user().

2012-06-13T01:28:16+00:00

This kills off the special sh32/64 versions and adopts the generic
version. It should be possible to optimize this for SH-4A unaligned
loads, but this is a corner case that can be supported incrementally.

sh64: Invert page fault fast-path error path values.

2012-05-14T07:44:45+00:00

This brings the sh64 version in line with the sh32 one with regards to
how errors are handled. Base work for further unification of the
implementations.

sh64: Utilize thread fault code encoding.

2012-05-14T06:07:52+00:00

This plugs in fault code encoding for the sh64 page fault, too.

sh64: Fixup build breakage from breakpoint handler rename.

2010-01-19T06:58:27+00:00

The breakpoint handler was renamed on sh32, but sh64 was overlooked in
the conversion. Fix it up now.

sh64: Use the shared FPU state restorer.

2010-01-19T06:55:27+00:00

This kills off the sh64-specific state restorer and switches over to
the generic one.

sh: TS_RESTORE_SIGMASK conversion.

2009-10-14T07:05:42+00:00

Replace TIF_RESTORE_SIGMASK with TS_RESTORE_SIGMASK and define our own
set_restore_sigmask() function.  This saves the costly SMP-safe set_bit
operation, which we do not need for the sigmask flag since TIF_SIGPENDING
always has to be set too.

Based on the x86 and powerpc change.
