2.6.9-rc4-mm1 HPET compile problems on AMD64

[Badari Pulavarty]

Hi Andrew,

I get following error while linking kernel on 2.6.9-rc4-mm1.
x86_64/kernel/time.c seems to have a dependency on char/hpet.c
driver. Its forcing me to use CONFIG_HPET. 

 LD      .tmp_vmlinux1
arch/x86_64/kernel/built-in.o(.init.text+0x2071): In function
`late_hpet_init':
arch/x86_64/kernel/entry.S:259: undefined reference to `hpet_alloc'
make: *** [.tmp_vmlinux1] Error 1

I used following fix to compile. I have no idea, if its right
or not.

Thanks,
Badari
