80f9507886 [PATCH] uml: fix syscall table by including $(SUBARCH)'s one, for x86-64
Reuse asm-x86-64/unistd.h to build our syscall table, like x86-64 already
does.

Like for i386, we must add some #defines for all the (right!) changes UML does
to x86-64 syscall table.

Note: I noted a bogus:
	[ __NR_sched_yield ] = (syscall_handler_t *) yield,

while doing this patch (which could only be a workaround for some strange bug,
but I would ignore this possibility).  I'm changing this without notice.

ddcd6b1757 [PATCH] uml: quick fix syscall table for x86_64
Fix the moved syscall table for the x86_64 SUBARCH:

- redirect __NR_chown and such to versions aware of 32-bit UIDs,

- avoid the useless hack for sys_nfsservctl,

- use sys_sendfile64 in the table rather than sys_sendfile.

- __NR_uselib is sys_ni_syscall on x86_64 (which does not support A.OUT).

- __NR_getrlimit is sys_getrlimit, not sys_old_getrlimit

5e7b83ffc6 [PATCH] uml: fix syscall table by including $(SUBARCH)'s one, for i386
Split the i386 entry.S files into entry.S and syscall_table.S which is
included in the previous one (so actually there is no difference between them)
and use the syscall_table.S in the UML build, instead of tracking by hand the
syscall table changes (which is inherently error-prone).

We must only insert the right #defines to inject the changes we need from the
i386 syscall table (for instance some different function names); also, we
don't implement some i386 syscalls, as ioperm(), nor some TLS-related ones
(yet to provide).

e9c527163d [PATCH] uml: move va_copy conditional def
GCC 2.95 uses __va_copy instead of va_copy.  Handle it inside compiler.h
instead of in a casual file, and avoid the risk that this breaks with a newer
compiler (which it could do).

c45166be3c [PATCH] uml: support AES i586 crypto driver
We want to make possible, for the user, to enable the i586 AES implementation.
This requires a restructure.

- Add a CONFIG_UML_X86 to notify that we are building a UML for i386.

- Rename CONFIG_64_BIT to CONFIG_64BIT as is used for all other archs

- Tell crypto/Kconfig that UML_X86 is as good as X86

- Tell it that it must exclude not X86_64 but 64BIT, which will give the
  same results.

- Tell kbuild to descend down into arch/i386/crypto/ to build what's needed.

b05d85a87d [PATCH] uml: workaround old problematic sed behaviour
Old versions of sed from 1998 (predating the first release of gcc 2.95, but
still in use by debian stable) don't understand the single-line version of the
sed append command.  Since newer versions of sed still understand the...
ahem, "vintage" form of the command, change our code to use that.

6aec307283 [PATCH] uml: fix handling of no fpx_regs
Paolo 'Blaisorblade' Giarrusso <blaisorblade@yahoo.it>

Fix the error path, which is triggered when the processor misses the fpx
regs (i.e.  the "fxsr" cpuinfo feature).  For instance by VIA C3 Samuel2.

8e7a4f69e4 [PATCH] uml: add nfsd syscall when nfsd is modular
This trick is useless, because sys_ni.c will handle this problem by itself,
like it does even on UML for other syscalls.

Also, it does not provide the NFSD syscall when NFSD is compiled as a
module, which is a big problem.

9c340d80f6 [PATCH] uml: fix compilation for __CHOOSE_MODE addition
I had added the __CHOOSE_MODE syntax to fix some warnings with newer GCC's
in the uml-fix-cond-expr-as-lvalues-warning patch.

Here is the update from the version I sent to make it work also when only
one mode (TT or SKAS) is enabled.

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!
