      [PATCH] ppc64: update xmon debugger · 984aa1e8
      Andrew Morton authored
      From: Paul Mackerras <paulus@samba.org>
      
      This patch fixes a whole pile of problems in the xmon kernel debugger for
      ppc64.  This basically makes xmon SMP-safe.  Now, when we enter xmon it
      sends an IPI to the other CPUs to get them into xmon too.  It also changes
      the way we do single-stepping and breakpoints so that we don't have to
      remove a breakpoint to proceed from it (instead we either emulate the
      instruction where the breakpoint was, or execute it out of place).  With
      this patch, if we get an exception inside xmon, it will just return to the
      xmon command loop instead of hanging the system as at present.
      
      The patch is quite large because it updates the disassembler to the latest
      version from binutils (trimmed a bit), which is why I didn't cc lkml.

      [PATCH] ppc64: fix inline version of _raw_spin_trylock · 68a6cd9b
      Andrew Morton authored
      From: Paul Mackerras <paulus@samba.org>
      
      When I added the out-of-line spinlocks on PPC64, I inadvertently introduced
      a bug in the inline version of _raw_spin_trylock, where it returns the
      opposite of what it should return.  The patch below fixes it.

      [PATCH] ppc64: Fix readq & writeq · fb5c2d93
      Andrew Morton authored
      From: Benjamin Herrenschmidt <benh@kernel.crashing.org>
      
      This fixes busted asm constraints for readq & writeq implementation on
      ppc64 that resulted in garbage beeing generated for writeq (plus an obvious
      mistake in the prototype).

      [PATCH] fix for stuck cpus at boot] · e0689d5d

      When hotplug cpu isn't enabled, cpu_is_offline is always false.  I had a stuck
      cpu at boot that resulted in a lockup because we tried to start a migration
      thread on it.  Instead of cpu_is_offline we can use !cpu_online which should
      cover both the hotplug cpu enabled and disabled cases.
