Plus sanitizing the asm glue and do_notify_resume() on alpha, fixing the "disabled irq while running task_work stuff" breakage there. At that point the rest of kernel_thread/kernel_execve/sys_execve work can be done independently for different architectures. The only pending bits that do depend on having all architectures converted are restrictred to fs/* and kernel/* - that'll obviously have to wait for the next cycle. I thought we'd have to wait for all of them done before we start eliminating the longjump-style insanity in kernel_execve(), but it turned out there's a very simple way to do that without flagday-style changes." * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/signal: alpha: switch to saner kernel_execve() semantics arm: switch to saner kernel_execve() semantics x86, um: convert to saner kernel_execve() semantics infrastructure for saner ret_from_kernel_thread semantics make sure that kernel_thread() callbacks call do_exit() themselves make sure that we always have a return path from kernel_execve() ppc: eeh_event should just use kthread_run() don't bother with kernel_thread/kernel_execve for launching linuxrc alpha: get rid of switch_stack argument of do_work_pending() alpha: don't bother passing switch_stack separately from regs alpha: take SIGPENDING/NOTIFY_RESUME loop into signal.c alpha: simplify TIF_NEED_RESCHED handling 2012-10-12T17:35:22Z Al Viro viro@zeniv.linux.org.uk 2012-10-11T01:35:42Z urn:sha1:22e2430d60dbdfcdd732a086e9ef2dbd74c266d1 Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> 2012-10-10T03:02:25Z Linus Torvalds torvalds@linux-foundation.org 2012-10-10T03:02:25Z urn:sha1:42859eea96ba6beabfb0369a1eeffa3c7d2bd9cb Pull generic execve() changes from Al Viro: "This introduces the generic kernel_thread() and kernel_execve() functions, and switches x86, arm, alpha, um and s390 over to them." * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/signal: (26 commits) s390: convert to generic kernel_execve() s390: switch to generic kernel_thread() s390: fold kernel_thread_helper() into ret_from_fork() s390: fold execve_tail() into start_thread(), convert to generic sys_execve() um: switch to generic kernel_thread() x86, um/x86: switch to generic sys_execve and kernel_execve x86: split ret_from_fork alpha: introduce ret_from_kernel_execve(), switch to generic kernel_execve() alpha: switch to generic kernel_thread() alpha: switch to generic sys_execve() arm: get rid of execve wrapper, switch to generic execve() implementation arm: optimized current_pt_regs() arm: introduce ret_from_kernel_execve(), switch to generic kernel_execve() arm: split ret_from_fork, simplify kernel_thread() [based on patch by rmk] generic sys_execve() generic kernel_execve() new helper: current_pt_regs() preparation for generic kernel_thread() um: kill thread->forking um: let signal_delivered() do SIGTRAP on singlestepping into handler ... 2012-10-09T20:28:45Z Al Viro viro@ZenIV.linux.org.uk 2012-10-08T02:27:32Z urn:sha1:37185b33240870719b6b5913a46e6a441f1ae96f Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Richard Weinberger <richard@nod.at> 2012-10-01T02:53:32Z Al Viro viro@zeniv.linux.org.uk 2012-09-22T00:32:29Z urn:sha1:1f02ab4a237086095bd584f3446da307ac2d02e6 Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> 2012-09-27T16:04:55Z Al Viro viro@zeniv.linux.org.uk 2012-09-20T13:28:25Z urn:sha1:d2ce4e92fa4f79a5fdb4cc912b411280afe21697 we only use that to tell copy_thread() done by syscall from that done by kernel_thread().
