um: disable scan_elf_aux() on x86_64

2011-07-26T03:57:13+00:00

Reusing the host's vDSO makes only sense on x86_32.

um: remove SIGHUP handler

2011-05-25T15:39:40+00:00

The UML kernel ignores SIGHUP anyway.  This handler is in vain.

um: fix UML_LIB_PATH

2011-05-25T15:39:40+00:00

UML_LIB_PATH is hardcoded to /usr/lib/uml/, on 64bit systems UML_LIB_PATH
needs to be /usr/lib64/uml/.

uml: fix build when SLOB is enabled

2008-05-13T15:02:22+00:00

Reintroduce uml_kmalloc for the benefit of UML libc code.  The
previous tactic of declaring __kmalloc so it could be called directly
from the libc side of the house turned out to be getting too intimate
with slab, and it doesn't work with slob.

So, the uml_kmalloc wrapper is back.  It calls kmalloc or whatever
that translates into, and libc code calls it.

kfree is left alone since that still works, leaving a somewhat
inconsistent API.

uml: install panic notifier earlier

2008-02-05T17:44:29+00:00

It turns out that if there's a panic early enough, UML will just sit there in
the LED-blinking loop because the panic notifier hadn't been installed yet.

This patch installs it earlier.

It also fixes the problem which exposed the hang, namely that if you give UML
a zero-sized initrd, it will ask alloc_bootmem for zero bytes, and that will
cause the panic.

While I was in initrd.c, I gave it a style makeover.

Prompted by checkpatch, I moved a couple extern declarations of uml_exitcode
to kern_util.h.

uml: code tidying under arch/um/os-Linux

2008-02-05T17:44:24+00:00

This patch contains varied fixes and improvements for some files under
arch/um/os-Linux/, such as a typo fix in a perror message, a missing
argument fix for a printf, some constifying for pointers and so on.

[ jdike - made sigprocmask failure return -errno instead of -1 ]

uml: eliminate SIGALRM

2007-10-16T16:43:08+00:00

Now that ITIMER_REAL is no longer used, there is no need for any use of
SIGALRM whatsoever.  This patch removes all mention of it.

In addition, real_alarm_handler took a signal argument which is now always
SIGVTALRM.  So, that is gone.

uml: style fixes pass 3

2007-10-16T16:43:05+00:00

Formatting changes in the files which have been changed in the course
of folding foo_skas functions into their callers.  These include:
	copyright updates
	header file trimming
	style fixes
	adding severity to printks

These changes should be entirely non-functional.

uml: remove code made redundant by CHOOSE_MODE removal

2007-10-16T16:43:05+00:00

This patch makes a number of simplifications enabled by the removal of
CHOOSE_MODE.  There were lots of functions that looked like

	int foo(args){
		foo_skas(args);
	}

The bodies of foo_skas are now folded into foo, and their declarations (and
sometimes entire header files) are deleted.

In addition, the union uml_pt_regs, which was a union between the tt and skas
register formats, is now a struct, with the tt-mode arm of the union being
removed.

It turns out that usr2_handler was unused, so it is gone.
