      x86: fix oprofile + hibernation badness · 80a8c9ff
      Andi Kleen 提交于
      Vegard Nossum reported oprofile + hibernation problems:
      
      > Now some warnings:
      >
      > ------------[ cut here ]------------
      > WARNING: at /uio/arkimedes/s29/vegardno/git-working/linux-2.6/kernel/smp.c:328 s
      > mp_call_function_mask+0x194/0x1a0()
      
      The usual problem: the suspend function when interrupts are
      already disabled calls smp_call_function which is not allowed with
      interrupt off. But at this point all the other CPUs should be already
      down anyways, so it should be enough to just drop that.
      
      This patch should fix that problem at least by fixing cpu hotplug&
      suspend support.

      x86, SGI UV: hardcode the TLB flush interrupt system vector · 99dd8713
      Cliff Wickman 提交于
      The UV TLB shootdown mechanism needs a system interrupt vector.
      
      Its vector had been hardcoded as 200, but needs to moved to the reserved
      system vector range so that it does not collide with some device vector.
      
      This is still temporary until dynamic system IRQ allocation is provided.
      But it will be needed when real UV hardware becomes available and runs 2.6.27.

      x86: fix Xorg startup/shutdown slowdown with PAT · 80c5e73d
      Venki Pallipadi 提交于
      Rene Herman reported significant Xorg startup/shutdown slowdown due
      to PAT. It turns out that the memtype list has thousands of entries.
      
      Add cached_entry to list add routine, in order to speed up the
      lookup for sequential reserve_memtype calls.

      x86: fix "kernel won't boot on a Cyrix MediaGXm (Geode)" · c6744955
      Samuel Sieb 提交于
      Cyrix MediaGXm/Cx5530 Unicorn Revision 1.19.3B has stopped
      booting starting at v2.6.22.
      
      The reason is this commit:

      >     x86: Replace NSC/Cyrix specific chipset access macros by inlined functions.
      
      this commit activated a macro which was dormant before due to (buggy)
      macro side-effects.
      
      I've looked through various datasheets and found that the GXm and GXLV
      Geode processors don't have an incrementor.
      
      Remove the incrementor setup entirely.  As the incrementor value
      differs according to clock speed and we would hope that the BIOS
      configures it correctly, it is probably the right solution.
