[Lguest] [PATCH] use cpu capabilities macros

[Matias Zabaljauregui]

Hello Rusty,

           I'm getting these warning messages while building lguest (2.6.26):

  CC [M]  drivers/lguest/x86/core.o
drivers/lguest/x86/core.c: In function 'lguest_arch_host_init':
drivers/lguest/x86/core.c:483: warning: passing argument 2 of
'clear_bit' from incompatible pointer type
drivers/lguest/x86/core.c: In function 'lguest_arch_host_fini':
drivers/lguest/x86/core.c:494: warning: passing argument 2 of
'set_bit' from incompatible pointer type


The macros set_cpu_cap and clear_cpu_cap  use the right casting:



Use clear_cpu_cap and set_cpu_cap instead of clear_bit and set_bit
