[PATCH] uml: revert block driver use of host AIO

2005-10-12T15:22:26+00:00

The patch to use host AIO support that I submitted early after 2.6.13 exposed
some problems in the block driver.  I have fixes for these, but am not
comfortable putting them into 2.6.14 at this late date.  So, this patch reverts
the use of host AIO.

I will resubmit the original patch, plus fixes to the driver after 2.6.14
in order to get a reasonable amount of testing before they're exposed to
the general public.

[PATCH] uml: add mode=skas0 as a synonym of skas0

2005-10-10T15:36:00+00:00

Too many people were confused by skas0 and tried using "mode=skas0". And after
all, they are right - accept this.

[PATCH] uml: Fix sysrq-r support for skas mode

2005-10-04T20:22:01+00:00

The old code had the IP and SP coming from the registers in the thread
struct, which are completely wrong since those are the userspace
registers.  This fixes that by pulling the correct values from the
jmp_buf in which the kernel state of each thread is stored.

[PATCH] uml makefiles sanitized

2005-09-29T15:46:26+00:00

UML makefiles sanitized:
 - number of generated headers reduced to 2 (from user-offsets.c and
   kernel-offsets.c resp.).  The rest is made constant and simply
   includes those two.
 - mk_... helpers are gone now that we don't need to generate these
   headers
 - arch/um/include2 removed since everything under arch/um/include/sysdep
   is constant now and symlink can point straight to source tree.
 - dependencies seriously simplified.

[PATCH] uml: comment about cast build fix

2005-09-21T23:16:30+00:00

Explain why the casting we do to silence this warning is indeed safe.

It is because the field we're casting from, though being 64-bit wide, was filled
with a pointer in first place by ourselves.

[PATCH] uml: readd removed unistd.h inclusion

2005-09-21T23:16:30+00:00

Readd this header (deleted in 60d339f6fe0831060600c62418b71a62ad26c281). A
warning is spit out here about undeclared getpgrp().

[PATCH] uml: fix bogus HOST_ELF_CLASS symbol name

2005-09-21T23:16:30+00:00

Even if with a bit of misunderstanding, Al fixed this in commit
95608261dae863bc43292e6fbd946a3abd3aa49f.

Well, the symbol was intended to come from userspace (it exists there on normal
host), but since some hosts may miss that, using the kernel one is just as fine.
However, rename it to be named consistently with the rest.

Actually, he missed converting ELFCLASS32 to coming from kernel headers. For
consistence, add ELFCLASS64 too.

[PATCH] uml: remove include of asm/elf.h

2005-09-17T18:50:00+00:00

asm/elf.h is bad on x86_64, and i386 doesn't need it any more after Al's
cleanup.

[PATCH] uml: return a real error code

2005-09-17T18:50:00+00:00

do_aio used to return -1 on error instead of errno.

2005-09-17T18:50:00+00:00

The serial UML OS-abstraction layer patch (um/kernel dir).

This moves all system calls from mem_user.c and tempfile.c files under
os-Linux dir.
