      [PATCH] BLOCK: Revert patch to hack around undeclared sigset_t in linux/compat.h · 3f2e05e9
      由 David Howells 提交于 
      Revert Andrew Morton's patch to temporarily hack around the lack of a
declaration of sigset_t in linux/compat.h to make the block-disablement
patches build on IA64.  This got accidentally pushed to Linus and should
be fixed in a different manner.

Also make linux/compat.h #include asm/signal.h to gain a definition of
sigset_t so that it can externally declare sigset_from_compat().

This has been compile-tested for i386, x86_64, ia64, mips, mips64, frv, ppc and
ppc64 and run-tested on frv.

      [PATCH] replace cad_pid by a struct pid · 9ec52099
      由 Cedric Le Goater 提交于 
      There are a few places in the kernel where the init task is signaled.  The
ctrl+alt+del sequence is one them.  It kills a task, usually init, using a
cached pid (cad_pid).

This patch replaces the pid_t by a struct pid to avoid pid wrap around
problem.  The struct pid is initialized at boot time in init() and can be
modified through systctl with

	/proc/sys/kernel/cad_pid

[ I haven't found any distro using it ? ]

It also introduces a small helper routine kill_cad_pid() which is used
where it seemed ok to use cad_pid instead of pid 1.

      [PATCH] AVR32: Implement kernel_execve · c5f2420a
      由 Haavard Skinnemoen 提交于 
      Move execve() into arch/avr32/kernel/sys_avr32.c, rename it to
kernel_execve() and return the syscall return value directly without
setting errno.

This also gets rid of the __KERNEL_SYSCALLS__ stuff from unistd.h and
expands #ifdef __KERNEL__ to cover everything in unistd.h except the
__NR_foo definitions.

      [PATCH] remove remaining errno and __KERNEL_SYSCALLS__ references · 135ab6ec
      由 Arnd Bergmann 提交于 
      The last in-kernel user of errno is gone, so we should remove the definition
and everything referring to it.  This also removes the now-unused lib/execve.c
file that was introduced earlier.

Also remove every trace of __KERNEL_SYSCALLS__ that still remained in the
kernel.

      [PATCH] sh64: remove the use of kernel syscalls · 821278a7
      由 Arnd Bergmann 提交于 
      sh64 is using system call macros to call some functions from the kernel.

The old debug code can simply be removed, since we don't really have that much
of a need for it anymore, it was mostly something that was handy during the
initial bringup.  This also brings us closer to something that looks like
readable code again..

I also added a sane kernel_thread() implementation that gets away from this,
so that should take care of sh64 at least.

      [PATCH] provide kernel_execve on all architectures · fe74290d
      由 Arnd Bergmann 提交于 
      This adds the new kernel_execve function on all architectures that were using
_syscall3() to implement execve.

The implementation uses code from the _syscall3 macros provided in the
unistd.h header file.  I don't have cross-compilers for any of these
architectures, so the patch is untested with the exception of i386.

Most architectures can probably implement this in a nicer way in assembly or
by combining it with the sys_execve implementation itself, but this should do
it for now.
