2012-11-28sh64: fix altstack switching on sigreturnAl Viro
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. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2012-10-12vfs: define struct filename and have getname() return itJeff Layton
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. Signed-off-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2012-09-18sh: Fix up TIF_NOTIFY_RESUME sans TIF_SIGPENDING handling.Al Viro
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.

Does block_sigmask() + tracehook_signal_handler(); called when sigframe has been successfully built. All architectures converted to it; block_sigmask() itself is gone now (merged into this one). I'm still not too happy with the signature, but that's a separate story (IMO we need a structure that would contain signal number + siginfo + k_sigaction, so that get_signal_to_deliver() would fill one, signal_delivered(), handle_signal() and probably setup...frame() - take one).

2012-05-22sh: intc: Kill off special reservation interface.Paul Mundt
At present reserving the IRLs in the IRQ bitmap in addition to the dropping of the legacy IRQ pre-allocation prevent IRL IRQs from being allocated for the x3proto board. The only reason to permit reservations was to lock down possible hardware vectors prior to dynamic IRQ scanning, but this doesn't matter much given that the hardware controller configuration is sorted before we get around to doing any dynamic IRQ allocation anyways. Beyond that, all of the tables are __init annotated, so quite a bit more work would need to be done to support reconfiguring things like IRL controllers on the fly, much more than would ever make it worth the hassle.

2012-05-21sh: Kill off machvec IRQ hinting.Paul Mundt
Everything is using sparseirq these days, so we have no need to arbitrarily size nr_irqs ahead of time. The legacy IRQ pre-allocation likewise has no meaning for us, so that's killed off too. We now depend on nr_irqs expansion by the generic hardirq layer instead. It's also worth noting that the majority of boards had completely bogus values for their nr_irqs relative to their CPU and configurations, so this ends up correcting behaviour for quite a few platforms.
