sh64: fix altstack switching on sigreturn

2012-11-29T02:46:11+00:00

incidentally, declaring a local variable as __user (!) to make
sparse STFU is really sick.  Especially since sparse had been
100% right - it *is* a bug.

vfs: define struct filename and have getname() return it

2012-10-13T00:14:55+00:00

getname() is intended to copy pathname strings from userspace into a
kernel buffer. The result is just a string in kernel space. It would
however be quite helpful to be able to attach some ancillary info to
the string.

For instance, we could attach some audit-related info to reduce the
amount of audit-related processing needed. When auditing is enabled,
we could also call getname() on the string more than once and not
need to recopy it from userspace.

This patchset converts the getname()/putname() interfaces to return
a struct instead of a string. For now, the struct just tracks the
string in kernel space and the original userland pointer for it.

Later, we'll add other information to the struct as it becomes
convenient.

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: sh7269: Fix LCD pinmux

2012-08-09T04:16:55+00:00

There are two ports that can output the LCD data, therefore
they have to use separate pimux identifiers so we can select
the one we want to use.

sh: explicitly include sh_dma.h in setup-sh7722.c

setup-sh7722.c defines several objects, whose types are defined in
sh_dma.h, so, it has to be included explicitly.
