[PATCH] gcc-3.4.0 fixes for 2.6.6-rc3 x86_64 kernel

From: Mikael Pettersson <mikpe@csd.uu.se>

Here are some patches to fix compilation warnings from
gcc-3.4.0 in the 2.6.6-rc3 x86_64 kernel.

- puts() type conflict in boot/compressed/misc.c:
  rename to putstr(), just like i386 did
- cast-as-lvalue in ia32_copy_siginfo_from_user():
  use temporary
- code before declaration in io_apic.c:
  move decl up
- code before declaration in ioremap.c:
  move existing #ifndef up
- cast-as-lvalue (tons of them) from UP version of per_cpu():
  merged asm-generic's version
