Subject: [PATCH -tip] x86 - setup_per_cpu_areas cleanup
Date: Fri, 2 Jan 2009 21:51:32 +0300 [thread overview]
Message-ID: <20090102185132.GG5372@localhost> (raw)
Impact: cleanup
__alloc_bootmem and __alloc_bootmem_node do panic
for us in case of fail so no need for additional
checks here.
Also lets use pr_ macros for printing.
