[PATCH] ia64,kexec: declare ia64_mca_pal_base in mca.h rather than kexec.h

[Horms <horms@verge.net.au>]

* Kexec adds some code to arch/ia64/kernel/smp.c which needs ia64_mca_pal_base,
  so the kexec patch (actually the kdump patch) declares this
  per-cpu variable in include/asm-ia64/kexec.h.

* ia64_mca_pal_base is defined in arch/ia64/kernel/mca.c, so it
  seems to me that it would make a lot more sense to declare it in
  include/asm-ia64/mca.h.

* This patch moves the declaration.

* This patch is relative to Zou Nan hai's kdump patch which I rediffed
  and sent to linux-ia64 and fastboot on the 8th of June
  http://permalink.gmane.org/gmane.linux.ports.ia64/14320

* This patch will probably need manual merging with another patch to kexec.h
  that I sent yesterday, which related to removing some PTE macros.
  The merge should be trivial, and I'm happy to supply relative diff
  if need be.
