two kexec related hpet fixes from Ogawa Hirofumi. (the #ifdefs will be 
eliminated later on, these are the tested patches for -rc4)

Thanks!

Ingo, there is no such tree on kernel.org. Forgot to push it out?

hm, i found the reason - a wrong URI made it into the pull request. The 
correct uri is to the shared x86 tree:

   git://git.kernel.org/pub/scm/linux/kernel/git/x86/linux-2.6-x86.git

NOTE: i've meanwhile finished the testing of another fixlet so it's 3 
patches - i've re-pushed the whole tree because i first thought i forgot 
the pull. The pull request email is below.
