Martin Schwidefsky 94c12cc7d1 [S390] Inline assembly cleanup. 
Major cleanup of all s390 inline assemblies. They now have a common
coding style. Quite a few have been shortened, mainly by using register
asm variables. Use of the EX_TABLE macro helps  as well. The atomic ops,
bit ops and locking inlines new use the Q-constraint if a newer gcc
is used.  That results in slightly better code.

Thanks to Christian Borntraeger for proof reading the changes.

Martin Schwidefsky 1047aa7723 [PATCH] s390: const pointer uaccess 
Using __typeof__(*ptr) on a pointer to const makes the __x variable in
__get_user const as well.  The latest gcc will refuse to write to it.

Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2 
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!
