X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9a98e2f7326d626d75cab2fe108c34b733227918;p=pandora-kernel.git

[PATCH] remove fixup_cpu_present_map()

Since the addition of boot_cpu_init(), fixup_cpu_present_map() has been a
no-op.  That's because fixup_cpu_present_map() won't touch cpu_present_map if
it has any bits set, and boot_cpu_init() sets a bit.

So remove fixup_cpu_present_map().

A consequence of this (actually of the boot_cpu_init() change) is that the
architecture _must_ populate cpu_present_map itself (probably in
smp_prepare_cpus()).  fixup_cpu_present_map() won't do it any more.

If the architecture doesn't do this, it'll only bring up a single CPU.

The other side effect (though less serious) is that smp_prepare_boot_cpu() no
longer needs to mark the boot cpu in the online and present maps -
boot_cpu_init() does that for everyone (to make early printks work).
