      [IA64] CONFIG_KEXEC/CONFIG_CRASH_DUMP permutations · 45a98fc6
      Horms authored
      Actually, on reflection I think that there is a good case for
      keeping the options separate. I am thinking particularly of people
      who want a very small crashdump kernel and thus don't want to compile
      in kexec.
      
      The patch below should fix things up so that all valid combinations of
      KEXEC, CRASH_DUMP and VMCORE compile cleanly - VMCORE depends on
      CRASH_DUMP which is why I said valid combinations. In a nutshell
      it just untangles unrelated code and switches around a few defines.
      
      Please note that it creats a new file, arch/ia64/kernel/crash_dump.c
      This is in keeping with the i386 implementation.

      [IA64] Do not call SN_SAL_SET_CPU_NUMBER twice on cpu 0 · adf142e3
      Jay Lan authored
      This is an SN specific patch.
      
      Architectually, cpu_init is always called twice on cpu 0
      and thus resulted in two SN_SAL_SET_CPU_NUMBER calls.
      
      This was harmless in production kernel; however, it can
      cause problem on booting up a crashdump kernel at Altix.
      
      Here is the patch that detects the second sn_cpu_init
      call and skips the second call to SN_SAL_SET_CPU_NUMBER.

      [PATCH] netpoll: fix netpoll lockup · 3640543d
      Ingo Molnar authored
      current -git doesnt boot on my laptop due to netpoll not unlocking the
      tx lock in the else branch.
      
      booted this up on my laptop with lockdep enabled and there are no
      locking complaints and it works fine.

      [PATCH] lockdep: fix seqlock_init() · 99a3eb38
      Ingo Molnar authored
      seqlock_init() needs to use spin_lock_init() for dynamic locks, so that
      lockdep is notified about the presence of a new lock.
      
      (this is a fallout of the recent networking merge, which started using
      the so-far unused seqlock_init() API.)
      
      This fix solves the following lockdep-internal warning on current -git:
      
       INFO: trying to register non-static key.
       the code is fine but needs lockdep annotation.
       turning off the locking correctness validator.

      [PATCH] remove blk_queue_activity_fn · 2b02a179
      Boaz Harrosh authored
      While working on bidi support at struct request level
      I have found that blk_queue_activity_fn is actually never used.
      The only user is in ide-probe.c with this code:
      
      	/* enable led activity for disk drives only */
      	if (drive->media == ide_disk && hwif->led_act)
      		blk_queue_activity_fn(q, hwif->led_act, drive);
      
      And led_act is never initialized anywhere.
      (Looking back at older kernels it was used in the PPC arch, but was removed around 2.6.18)
      Unless it is all for future use off course.
      (this patch is against linux-2.6-block.git as off 2006/12/4)

      Franck Bui-Huu authored
      This patch makes paging_init() use highend_pfn/highstart_pfn globals.
      
      It removes the need of 'high' local which was needed only by HIGHMEM config.
      
      More important perhaps, it fixes a bug when HIGHMEM is set but there's
      actually no physical highmem (highend_pfn = 0)

      [MIPS] Discard .exit.text and .exit.data at runtime. · 2efac77e
      Ralf Baechle authored
      While the recent cset 86384d54 did improve
      things it didn't resolve all the problems.  So bite the bullet and discard
      .exit.text and .exit.data at runtime.  Which of course sucks because it
      bloats binaries with code that will never ever be used but it's the only
      thing that will work reliable as demonstrated by the function sd_major() in
      drivers/scsi/sd.c.
      
      Gcc may compile sd_major() using a jump table which it will put into
      .rodata.  If it also inlines sd_major's function body into exit_sd() which
      gcc > 3.4.x does.  If CONFIG_BLK_DEV_SD has been set to y we would like ld
      to discard exit_sd's code at link time.  However sd_major happens to
      contain a switch statement which gcc will compile using a jump table in
      .rodata on the architectures I checked.  So, when ld later discards
      .exit.text only the jump table in .rodata with its stale references to
      the discard .exit.text will be left which any no antique ld will honor
      with a link error.

      During boot we get:

      Herbert sayeth:
      
        Normally networking isn't invoked with interrupts turned off, but I
        suppose we don't have a choice here.  This is unique being a place where you
        can get called with BH on, off, or IRQs off.
      
        Given that this is only used for printk, the easiest solution is probably
        just to disable local IRQs instead of BH.
