      [PATCH] provide kernel_execve on all architectures · fe74290d
      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.

      [PATCH] kill wall_jiffies · 8ef38609
      Atsushi Nemoto 提交于
      With 2.6.18-rc4-mm2, now wall_jiffies will always be the same as jiffies.
      So we can kill wall_jiffies completely.
      
      This is just a cleanup and logically should not change any real behavior
      except for one thing: RTC updating code in (old) ppc and xtensa use a
      condition "jiffies - wall_jiffies == 1".  This condition is never met so I
      suppose it is just a bug.  I just remove that condition only instead of
      kill the whole "if" block.

      [PATCH] simplify update_times (avoid jiffies/jiffies_64 aliasing problem) · 3171a030
      Atsushi Nemoto 提交于
      Pass ticks to do_timer() and update_times(), and adjust x86_64 and s390
      timer interrupt handler with this change.
      
      Currently update_times() calculates ticks by "jiffies - wall_jiffies", but
      callers of do_timer() should know how many ticks to update.  Passing ticks
      get rid of this redundant calculation.  Also there are another redundancy
      pointed out by Martin Schwidefsky.
      
      This cleanup make a barrier added by
      5aee405c needless.  So this patch removes
      it.
      
      As a bonus, this cleanup make wall_jiffies can be removed easily, since now
      wall_jiffies is always synced with jiffies.  (This patch does not really
      remove wall_jiffies.  It would be another cleanup patch)

      [PATCH] Change panic_on_oops message to "Fatal exception" · 012c437d
      Horms 提交于
      Previously the message was "Fatal exception: panic_on_oops", as introduced
      in a recent patch whith removed a somewhat dangerous call to ssleep() in
      the panic_on_oops path.  However, Paul Mackerras suggested that this was
      somewhat confusing, leadind people to believe that it was panic_on_oops
      that was the root cause of the fatal exception.  On his suggestion, this
      patch changes the message to simply "Fatal exception".  A suitable oops
      message should already have been displayed.

      [PATCH] panic_on_oops: remove ssleep() · cea6a4ba
      Horms 提交于
      This patch is part of an effort to unify the panic_on_oops behaviour across
      all architectures that implement it.
      
      It was pointed out to me by Andi Kleen that if an oops has occured in
      interrupt context, then calling sleep() in the oops path will only cause a
      panic, and that it would be really better for it not to be in the path at
      all.
      
      This patch removes the ssleep() call and reworks the console message
      accordinly.  I have a slght concern that the resulting console message is
      too long, feedback welcome.
      
      For powerpc it also unifies the 32bit and 64bit behaviour.
      
      Fror x86_64, this patch only updates the console message, as ssleep() is
      already not present.

      [PATCH] genirq: rename desc->handler to desc->chip · d1bef4ed
      Ingo Molnar 提交于
      This patch-queue improves the generic IRQ layer to be truly generic, by adding
      various abstractions and features to it, without impacting existing
      functionality.
      
      While the queue can be best described as "fix and improve everything in the
      generic IRQ layer that we could think of", and thus it consists of many
      smaller features and lots of cleanups, the one feature that stands out most is
      the new 'irq chip' abstraction.
      
      The irq-chip abstraction is about describing and coding and IRQ controller
      driver by mapping its raw hardware capabilities [and quirks, if needed] in a
      straightforward way, without having to think about "IRQ flow"
      (level/edge/etc.) type of details.
      
      This stands in contrast with the current 'irq-type' model of genirq
      architectures, which 'mixes' raw hardware capabilities with 'flow' details.
      The patchset supports both types of irq controller designs at once, and
      converts i386 and x86_64 to the new irq-chip design.
      
      As a bonus side-effect of the irq-chip approach, chained interrupt controllers
      (master/slave PIC constructs, etc.) are now supported by design as well.
      
      The end result of this patchset intends to be simpler architecture-level code
      and more consolidation between architectures.
      
      We reused many bits of code and many concepts from Russell King's ARM IRQ
      layer, the merging of which was one of the motivations for this patchset.
      
      This patch:
      
      rename desc->handler to desc->chip.
      
      Originally i did not want to do this, because it's a big patch.  But having
      both "desc->handler", "desc->handle_irq" and "action->handler" caused a
      large degree of confusion and made the code appear alot less clean than it
      truly is.
      
      I have also attempted a dual approach as well by introducing a
      desc->chip alias - but that just wasnt robust enough and broke
      frequently.
      
      So lets get over with this quickly.  The conversion was done automatically
      via scripts and converts all the code in the kernel.
      
      This renaming patch is the first one amongst the patches, so that the
      remaining patches can stay flexible and can be merged and split up
      without having some big monolithic patch act as a merge barrier.

      - When setting a sighandler using sigaction() call, if the flag

      When we stop allocating percpu memory for not-possible CPUs we must not touch

      few instances of this bug, if any.  But the patch converts lots of open-coded

      [PATCH] sched: disable preempt in idle tasks · 5bfb5d69
      Nick Piggin 提交于
      Run idle threads with preempt disabled.
      
      Also corrected a bugs in arm26's cpu_idle (make it actually call schedule()).
      How did it ever work before?
      
      Might fix the CPU hotplugging hang which Nigel Cunningham noted.
      
      We think the bug hits if the idle thread is preempted after checking
      need_resched() and before going to sleep, then the CPU offlined.
      
      After calling stop_machine_run, the CPU eventually returns from preemption and
      into the idle thread and goes to sleep.  The CPU will continue executing
      previous idle and have no chance to call play_dead.
      
      By disabling preemption until we are ready to explicitly schedule, this bug is
      fixed and the idle threads generally become more robust.

      [PATCH] convert signal handling of NODEFER to act like other Unix boxes. · 69be8f18
      Steven Rostedt 提交于
      It has been reported that the way Linux handles NODEFER for signals is
      not consistent with the way other Unix boxes handle it.  I've written a
      program to test the behavior of how this flag affects signals and had
      several reports from people who ran this on various Unix boxes,
      confirming that Linux seems to be unique on the way this is handled.
      
      The way NODEFER affects signals on other Unix boxes is as follows:
      
      1) If NODEFER is set, other signals in sa_mask are still blocked.
      
      2) If NODEFER is set and the signal is in sa_mask, then the signal is
      still blocked. (Note: this is the behavior of all tested but Linux _and_
      NetBSD 2.0 *).
      
      The way NODEFER affects signals on Linux:
      
      1) If NODEFER is set, other signals are _not_ blocked regardless of
      sa_mask (Even NetBSD doesn't do this).
      
      2) If NODEFER is set and the signal is in sa_mask, then the signal being
      handled is not blocked.
      
      The patch converts signal handling in all current Linux architectures to
      the way most Unix boxes work.
      
      Unix boxes that were tested:  DU4, AIX 5.2, Irix 6.5, NetBSD 2.0, SFU
      3.5 on WinXP, AIX 5.3, Mac OSX, and of course Linux 2.6.13-rcX.
      
      * NetBSD was the only other Unix to behave like Linux on point #2. The
      main concern was brought up by point #1 which even NetBSD isn't like
      Linux.  So with this patch, we leave NetBSD as the lonely one that
      behaves differently here with #2.

      [PATCH] xtensa: remove old syscalls · 87591451
      Arnd Bergmann 提交于
      xtensa is now in -rc1, with the obsolete syscalls still in there, so I
      guess this about the last chance to correct the ABI.  Applying the patch
      obviously breaks all sorts of user space binaries and probably also
      requires the appropriate changes to be made to libc.
      
      On the other hand, if a decision is made to keep the broken interface, it
      should at least be a conscious one instead of an oversight.
