The default target for most powerpc platforms is zImage. The
zImage however is in arch/powerpc/boot and the mkspec script
was set up to get the kernel from the top level of the kernel
tree. This patch copies vmlinux to arch/powerpc/boot and then
copies the kernel to the tmp directory so the rpm can be made.

When Makefile.host is included, $(obj-dirs) is subjected to the
addprefix operation for the second time. Prefix only needs to be added
to the newly added directories, but not to those that came from
Makefile.lib.
This causes the build system to create unneeded empty directories in the
build tree when building in a separate directory. For instance,
lib/lib/zlib_inflate is created in the build tree.

There are several bugs in error handling in br_add_bridge:
- when dev_alloc_name fails, allocated net_device is not freed
- unregister_netdev is called when rtnl lock is held
- free_netdev is called before netdev_run_todo has a chance to be run after
unregistering net_device

Trimming the head of an skb by calling skb_pull can cause the packet
to become unaligned if the length pulled is odd. Since the length is
entirely arbitrary for a FIN packet carrying data, this is actually
quite common.
Unaligned data is not the end of the world, but we should avoid it if
it's easily done. In this case it is trivial. Since we're discarding
all of the head data it doesn't matter whether we move skb->data forward
or back.
However, it is still possible to have unaligned skb->data in general.
So network drivers should be prepared to handle it instead of crashing.
This patch also adds an unlikely marking on len < headlen since partial
ACKs on head data are extremely rare in the wild. As the return value
of __pskb_trim_head is no longer ever NULL that has been removed.

After removal of fixup_cpu_present_map() function Alpha ended up with an empty
cpu_present_map, so secondary CPUs on SMP systems are not being started.
Worse, on some platforms we route interrupts to secondary CPUs using
cpu_possible_map which is still populated properly. As a result, these
interrupts go nowhere so the machines like DP264 aren't able to boot even with
a primary CPU.
Fixed basically by s/cpu_present_mask/cpu_present_map/.
Thanks to Ernst Herzberg for reporting the bug and testing the fix.
