[TCP]: Avoid skb_pull if possible when trimming head

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

The only interrupts >= 64 are the thread interrupt sources, and there

lower byte of IXP23XX_PRODUCT_ID is identical to the lower byte of

Stepping A1 of the ixp2350, which has a PRODUCT_ID of 0x401, has '02'

0x402, has '04' in the lower byte of processor_id.

[PATCH] slab.c: fix offslab_limit bug

mm/slab.c's offlab_limit logic is totally broken.

Firstly, "offslab_limit" is a global variable while it should either be
calculated in situ or should be passed in as a parameter.

Secondly, the more serious problem with it is that the condition for
calculating it:

               if (!(OFF_SLAB(sizes->cs_cachep))) {
                       offslab_limit = sizes->cs_size - sizeof(struct slab);
                       offslab_limit /= sizeof(kmem_bufctl_t);

is in total disconnect with the condition that makes use of it:

               /* More than offslab_limit objects will cause problems */
               if ((flags & CFLGS_OFF_SLAB) && num > offslab_limit)
                       break;

but due to offslab_limit being a global variable this breakage was
hidden.

Up until lockdep came along and perturbed the slab sizes sufficiently so
that the first off-slab cache would still see a (non-calculated) zero
value for offslab_limit and would panic with:

  kmem_cache_create: couldn't create cache size-512.

  Kernel panic - not syncing: kmem_cache_create(): failed to create slab `size-512'

Paolo Ornati's config on x86_64 managed to trigger it.

The fix is to move the calculation to the place that makes use of it.
This also makes slab.o 54 bytes smaller.

Btw., the check itself is quite silly. Its intention is to test whether
the number of objects per slab would be higher than the number of slab
control pointers possible. In theory it could be triggered: if someone
tried to allocate 4-byte objects cache and explicitly requested with
CFLGS_OFF_SLAB. So i kept the check.

Out of historic interest i checked how old this bug was and it's
ancient, 10 years old! It is the oldest hidden and then truly triggering
bugs i ever saw being fixed in the kernel!
