7ef416c4b8 [ARM] Improve csum_fold, cleanup csum_tcpudp_magic()
csum_fold doesn't need two assembly instructions to perform its task,
it can simply add the high and low parts together by rotating by 16
bits, and the carry into the upper-16 bits will automatically happen.

Also, since csum_tcpudp_magic() is just csum_tcpudp_nofold + csum_fold,
use those two functions to achieve this.  Also note that there is a
csum_fold() at the end of ip_fast_csum() as well, so use the real
csum_fold() there as well.

Boot tested on Versatile.

62500d1f8e [ARM] 3292/1: Fix memory corruption in asm-arm/checksum.h: ip_fast_csum()
Patch from Richard Purdie

ip_fast_csum() accesses memory via a pointer (iph) within an
asm function. To prevent memory corruption when the function is
inlined, it needs "memory" on the clobber list.

This fixes ip checksum errors reported by a Zaurus user.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
