      [PATCH] More 3.4 compilation fixes · 71efc910
      Andrew Morton authored
      From: Jan Hubicka <jh@suse.cz>
      
      GCC now converts sprintf (a,"%s",b) to strcpy.  This lose on kernel as
      strcpy is not inlined and not present in library, so one gets linker
      failure.  It seems to make sense to apply this optimization by hand.

      [PATCH] Fix inlining failure (all GCCs) in parport · b3f36a2a
      Andrew Morton authored
      From: Jan Hubicka <jh@suse.cz>
      
      GCC never inline extern inline function redefined by new body (because it is
      not clear what body one should choose)
      
      parport contains such duplicated functions for apparently no good reasons.
      Both copies differ slightly, not sure whether it is intentional or just
      garbage.

      [PATCH] gcc-3.5: _exit fix · 1f98dc7e
      Andrew Morton authored
      include/asm/unistd.h:397: warning: conflicting types for built-in function '_exit'
      
      
      Just remove the dang thing - nobody uses _exit().
      
      Except for the vmware stub, which breaks.  So I kindly exported do_exit() to
      kernel modules, just for vmware...

      [PATCH] string fixes for gcc 3.4 · c545699a
      Andrew Morton authored
      From: Andi Kleen <ak@muc.de>
      
      gcc 3.4 optimizes sprintf(foo,"%s",string) into strcpy.  Unfortunately that
      isn't seen by the inliner and linux/i386 has no out-of-line strcpy so you
      end up with a linker error.
      
      This patch adds out of line copies for most string functions to avoid this.
      Actually it doesn't export them to modules yet, that would be the next
      step.
      
      BTW In my opinion we shouldn't use inline string functions at all.  The
      __builtin_str* in modern gcc are better (I used them very successfully on
      x86-64) and for the bigger functions like strrchr,strtok et.al.  it just
      doesn't make any sense to inline them or even code them in assembler.
      
      Also fix the bcopy prototype gcc was complaining about.

      [PATCH] Fix more gcc 3.4 warnings · d75cb184
      Andrew Morton authored
      From: Andi Kleen <ak@muc.de>
      
      Just many more warning fixes for a gcc 3.4 snapshot.
      
      It warns for a lot of things now, e.g.  for ?: and ({ ...  }) and casts as
      lvalues.  And for functions marked inline in headers, but no body.
      
      Actually there are more warnings, i stopped fixing at some point.  Some of
      the warnings seem to be dubious (e.g.  the binfmt_elf.c one, which looks
      more like a compiler bug to me)
      
      I also fixed the _exit() prototype to be void because gcc was complaining
      about this.

      [PATCH] sisfb update · 60677978
      Andrew Morton authored
      From: Thomas Winischhofer <thomas@winischhofer.net>
      
      sisfb is simply broken in current 2.6.x.  This patch updates sisfb to the
      current development version which no less than 11 months ahead of the version
      in the kernel.
      
      Updated includes
      
      - many fixes (duh)
      
      - support for new chipsets (661, 741, 760)
      
      - support for new video bridges (301C, 302ELV)
      
      - removal of all offending fp code (as discussed earlier this month)
      
      - a lot of code clean-up (which is the main reason for its size)

      [PATCH] kbuild: Unmangle include options for gcc · 9f61b232
      Andrew Morton authored
      From: Sam Ravnborg <sam@ravnborg.org>
      
      When utilising the make O=...  option the include options for gcc were
      mangled even when absolute paths was used.  Also remove duplication of
      CPPFLAGS.  They were assigned twice.  [It is still possible for
      architectures to modify CPPFLAGS].
      
      This patch allows xconfig to be build with make O=...  xconfig.It will also
      help development of external modules with absolute paths for their -I
      options.
      
      Note: As a side effect a full recompile of the kernel takes place due to
      changes in number of gcc options.

      [PATCH] ia32 MSI vector handling fix · 49596747
      Andrew Morton authored
      From: "Nakajima, Jun" <jun.nakajima@intel.com>
      
      To get the vector-based interrupt handling work, we need to give the vector
      number to device drivers instead of the IRQ if IRQ < 16.  It was not
      happening for SCI, and the patch fixes it.  In many cases, the IRQ for SCI is
      9, and the problem was not detected, but one particular machine exposed the
      bug.

      [PATCH] lock_cpu_hotplug only if CONFIG_CPU_HOTPLUG · 5d790751
      Andrew Morton authored
      From: Rusty Russell <rusty@rustcorp.com.au>
      
      The cpucontrol mutex is not required when no cpus can go up and down.
      Andrew wrote a wrapper for it to avoid #ifdefs, this expands that to only
      be defined for CONFIG_HOTPLUG_CPU, and uses it everywhere.
      
      The only downside is that the cpucontrol lock was overloaded by my recent
      patch to net/core/flow.c to protect it from reentrance, so this
      reintroduces the local flow_flush_sem.  This code isn't speed critical, so
      taking two locks when CONFIG_HOTPLUG_CPU=y is not really an issue.

      [PATCH] quiet down SMP boot messages · 9f078ca2
      Andrew Morton authored
      From: Jes Sorensen <jes@trained-monkey.org>
      
      I'd like to propose the following for 2.6.1-mm/2.6.2. On systems with a
      large number of CPUs the number of printk's flowing by for each CPU
      booting starts becoming a real console hog.
      
      The following patch eliminates a couple of them (already sent a patch to
      David for the ia64 specific ones) as well as changes the
      "Building zonelist : X" in "Built Y zonelists". IMHO it doesn't make any
      sense to print for each zonelist since it's run in a for loop running
      from 0 to Y-1 anyway.
      
      The patch nukes a few new printk's that were introduced with the
      scheduler changes to the NUMA code in -mm3, if these are still needed
      then I won't fight for that part of the patch.

      [PATCH] Allow PCI BARs that start at 0 · df9b5954
      Andrew Morton authored
      From: Anton Blanchard <anton@samba.org>
      
      We have IO BARs on ppc64 machines that begin at address 0. The current
      pci probe code will ignore anything that starts at 0. Remove these checks.

      [PATCH] Remove useless argument from __ste_allocate() · 8e9bd4e6

      In the current ppc64 code the function __ste_allocate() in

      [PATCH] Make PPC601_SYNC_FIX depend on pmac||prep · f13f8135
      Andrew Morton authored
      From: Tom Rini <trini@kernel.crashing.org>
      
      The following has been approved by Paul, FWIW.
      
      The following patch makes PPC601_SYNC_FIX depend on PPC_PMAC || PPC_PREP.
      It used to depend on ALL_PPC I believe, but this was (at least
      semi-intentionally I gather) backed out.  The last time this was discussed,
      the only platforms old enough to have a 601 to support were pmacs and
      preps, so it makes some sense to only ask for these machines.

      - Clean-up the KGDB interface such that we allow for a kgdb_map_scc call,
        but do not require one.
      
      - Add gen550 prototypes to <asm/kgdb.h>
      
      - PPC_GEN550 backend code doesn't depend on 8250_SERIAL.

      [PATCH] Fix race in sched_exit() · 5eef46a9
      Andrew Morton authored
      From: Martin Schwidefsky <schwidefsky@de.ibm.com>
      
      Fix a race on sleep_avg in sched_exit().
      
      The symptom I saw on 64-bit s390 has been a fixpoint divide exception
      because sleep_avg had a value > NS_MAX_SLEEP_AVG.  I tracked it down and
      the problem is sched_exit which recalculates the parents sleep average
      without taking the runqueue lock.  schedule() subtracts run_time from
      sleep_avg of the previous process.  This can turn out negative and is
      corrected shortly after the subtraction but that is already too late.
      sched_exit() already read the negative value an miscalculated the parents
      sleep_avg -> bang.
      
      I fixed this by adding task_rq_lock/task_rq_unlock to sched_exit().
