23db764d3d [PATCH] Switch s390 to NO_IOMEM

   patch from Al and the dma-mapping patch from Heiko we can get rid of
   iomem and all associated definitions."

So we'll just need to replace NO_IOPORT with NO_IOMEM in Kconfig and
kill arch/s390/mm/ioremap.c.

BTW, there's an annoying bit of junk in there - IO_SPACE_LIMIT.  We
only need it for /proc/ioports, which AFAICS shouldn't even be there
on s390 (or uml).  OTOH, removing that thing would mean a user-visible
change - we go from "empty file in /proc" to "no such file in /proc"...

3b0b4af2c7 [S390] Simplify virt_to_phys.
No need to use lrag in 64 bit addressing mode since lra will do the
same.

Use page_to_phys and pfn_to_page to avoid open-coded mem_map usage.

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.

39b083fe1c [S390] empty function defines.
Use do { } while (0) constructs instead of empty defines to avoid
subtle compile bugs.

Compile fix: add missing __raw_read* and __raw_write* defines to
include/asm-s390/io.h.
These are mandatory since patch c27a0d75b3
was merged.

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!
