      [POWERPC] 83xx: Don't call ioremap in the reset function · c75f902b
      Kumar Gala authored 
      It's possibly that we get an reset requestion when interrupts are disabled.
(For example an oops in an interrupt handler).  Therefor, we can't call
ioremap in the reset function.  Moving the ioremap of the registers we
need access to an arch_initcall helps the problem.

However we still have a window between boot and the arch_initcall in
which the register pointer will not be setup and thus we spin if the reset
function is called.  If one needs to ensure even this case is covered, look
at use of the watchdog provided on 83xx to reset the processor.

      [POWERPC] 83xx: Fix Kconfig to only enable FP math emulation for the MPC832x · 4d52719a
      Kumar Gala authored 
      Updated MATH_EMULATION depends to be on PPC_MPC832x instead of PPC_83xx.  Only
the the MPC832x has no floating point unit in the core.  Updated the other
83xx defconfigs that got math emulation turned on incorrectly.

      [PATCH] x86: fix PDA variables to work during boot · 9ee79a3d
      James Bottomley authored 
      The current PDA code, which went in in post 2.6.19 has a flaw in that it
doesn't correctly cycle the GDT and %GS segment through the boot PDA,
the CPU PDA and finally the per-cpu PDA.

The bug generally doesn't show up if the boot CPU id is zero, but
everything falls apart for a non zero boot CPU id.  The basically kills
voyager which is perfectly capable of doing non zero CPU id boots, so
voyager currently won't boot without this.

The fix is to be careful and actually do the GDT setups correctly.

      [PATCH] vmx: Fix register constraint in launch code · e0015489
      Herbert Xu authored 
      Both "=r" and "=g" breaks my build on i386:

  $ make
    CC [M]  drivers/kvm/vmx.o
  {standard input}: Assembler messages:
  {standard input}:3318: Error: bad register name `%sil'
  make[1]: *** [drivers/kvm/vmx.o] Error 1
  make: *** [_module_drivers/kvm] Error 2

The reason is that setbe requires an 8-bit register but "=r" does not
constrain the target register to be one that has an 8-bit version on
i386.

According to

	http://gcc.gnu.org/bugzilla/show_bug.cgi?id=10153

the correct constraint is "=q".
