2014-08-06T11:03:09+00:00

Use the more generic functions get_signal() signal_setup_done()
for signal delivery.

parisc: Remove arch/parisc/kernel/sys32.h header

2013-07-31T21:42:21+00:00

The KERNEL_SYSCALL define is not used anymore so the header can be
removed.

Pull signal handling cleanups from Al Viro:
 "This is the first pile; another one will come a bit later and will
  contain SYSCALL_DEFINE-related patches.

   - a bunch of signal-related syscalls (both native and compat)
     unified.

   - a bunch of compat syscalls switched to COMPAT_SYSCALL_DEFINE
     (fixing several potential problems with missing argument
     validation, while we are at it)

   - a lot of now-pointless wrappers killed

   - a couple of architectures (cris and hexagon) forgot to save
     altstack settings into sigframe, even though they used the
     (uninitialized) values in sigreturn; fixed.

   - microblaze fixes for delivery of multiple signals arriving at once

   - saner set of helpers for signal delivery introduced, several
     architectures switched to using those."

parisc: don't bother looping in do_signal()

2012-10-01T13:58:14+00:00

entry.S code had been looping until no pending signals are left
since 2005 anyway; no need to bother with that in do_signal()
itself.  If the failure to set a sigframe up raises SIGSEGV,
we'll just pick it up the next time around the loop(s) in entry.S
anyway.
