[PATCH] ACPI: cpufreq, processor: fix compile error in drivers/acpi/processor_perflib.c

[Miao Xie <miaox@cn.fujitsu.com>]

When trying to build 2.6.28-rc1 on ia64, make aborts with:

  CC      drivers/acpi/processor_perflib.o
  drivers/acpi/processor_perflib.c:41:28: error: asm/cpufeature.h: No such file or directory
  drivers/acpi/processor_perflib.c: In function ‘acpi_processor_get_performance_info’:
  drivers/acpi/processor_perflib.c:364: error: implicit declaration of function ‘boot_cpu_has’
  drivers/acpi/processor_perflib.c:364: error: ‘X86_FEATURE_EST’ undeclared (first use in this function)
  drivers/acpi/processor_perflib.c:364: error: (Each undeclared identifier is reported only once
  drivers/acpi/processor_perflib.c:364: error: for each function it appears in.)
  make[2]: *** [drivers/acpi/processor_perflib.o] Error 1
  make[1]: *** [drivers/acpi] Error 2
  make: *** [drivers] Error 2

this patch fix it.
