Hopefully this will make it more maintainable and less error prone.
Code makes use of search_exception_tables(). Since it calls this
function before the kernel exeception table is sorted, there is an
early call to sort_main_extable().This way it's easy to use the already present infrastructure of fixup
sections. Also this would allows to easily convert the rest of
head[31|64].S into C code.Signed-off-by: Heiko Carstens

cpu_relax() has barrier() semantics hence there is no need to use both
of them in conjunction in sclp_sync_wait(). Also change cpu_relax()
so it's more obvious that it has barrier semantics.Signed-off-by: Heiko Carstens

local_bh_disable/_local_bh_enable must not be called if in_irq() is
true. Besides that if in_interrupt() is true bottom halves are
disabled anyway.Signed-off-by: Heiko Carstens

Requests are aborted when the sclp interface reports 'not operational'
even though they may still be active at the sclp, leading to concurrent
writes to request memory by both the kernel and the sclp interface.
Do not abort requests for which the sclp interface reports not
operational status during request retry.Signed-off-by: Peter Oberparleiter 5A

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.

When the sclp interface takes very long to serve a request, the sclp core
driver will report a failed request to the sclp tty driver even though the
request is still being processed by the sclp interface. Eventually the sclp
interface completes the request and updates some fields in the request buffer
which leads to a corrupted tty pages list. The next time function
sclp_tty_write_room is called, the corrupted list will be traversed, resulting
in an oops.To avoid this remove the busy retry limit and increase retry intervals.

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!
