... rather than open-coding the 64bit versions. endian.h has those guys.

Style fixes for the rest of the drivers. arch/um/drivers should be pretty
CodingStyle-compliant now.Except for the ubd driver, which will have to be treated separately.

I sent a patch, it was applied as cda402b283c34a24b091f78eee116963e9494762,
then it was applied again as 181ae4005d0a4010802be534d929b38c42b9ac06 by
mistake. But while the 1st time it modified (correctly) cow_header_v3, the
2nd it modified cow_header_v3_broken.Signed-off-by: Paolo 'Blaisorblade' Giarrusso

This is the minimal fix to make 64-bit UML binaries create 32-bit
compatible COW files and read them.I've indeed tested that current code doesn't do this - the code gets
SIGFPE for a division by a value read at the wrong place, where 0 is
found.Signed-off-by: Paolo 'Blaisorblade' Giarrusso

Fix two harmless warnings in 64-bit compilation (the 2nd doesn't trigger for
now because of a missing __attribute((format)) for cow_printf, but next
patches fix that).Signed-off-by: Paolo 'Blaisorblade' Giarrusso

- Correct the layout of all header versions - make all them well-specified
for any external event. As we don't have 1-byte or 2-byte wide fields, the
32-bit layout (historical one) has no extra padding, so we can safely add
__attribute__((packed)).- Add detection and reading of the broken 64-bit COW format which has been
around for a while - to allow safe migration to the correct 32-bit format.
Safe detection is possible, thanks to some luck with the existing format,
and it works in practice.Signed-off-by: Paolo 'Blaisorblade' Giarrusso

return the error we got!Signed-off-by: Paolo 'Blaisorblade' Giarrusso

talking about V3 format. Also resync with our userspace code utility a bit

After restoring the existing code, make it work also when included in
kernelspace code (which isn't currently the case, but at least this will prevent
people from "fixing" it as just happened).
Whitespace is fixed in next patch - it cluttered the diff too much.Signed-off-by: Paolo 'Blaisorblade' Giarrusso

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!
