[PATCH] uml: fix timer initialization

2005-06-25T23:24:35+00:00

In skas mode, the call to uml_idle_timer permanently shut off the virtual
timer, resulting in no timer ticks to anything but the idle thread.  This is
likely the cause of the soft lockups that are seen sporadically in recent
UMLs.

[PATCH] uml: fork cleanup

2005-06-25T23:24:35+00:00

Fix the do_fork calling convention: normal arch pass the regs and the new sp
value to do_fork instead of NULL.

Currently the arch-independent code ignores these values, while the UML code
(actually it's copy_thread) gets the right values by itself.

With this patch, things are fixed up.

[PATCH] kstrdup: convert a few existing implementations

2005-06-23T16:45:18+00:00

Convert a bunch of strdup() implementations and their callers to the new
kstrdup().  A few remain, for example see sound/core, and there are tons of
open coded strdup()'s around.  Sigh.  But this is a start.

[PATCH] uml: remove 2_5compat.h

2005-05-28T23:46:11+00:00

Remove old useless header that was used in Ye Olde Times during 2.4->2.5
porting to abstract differences.  It's definitions are no more used anyway, so
let's finally kill it.

[PATCH] uml: Fix process exit race

2005-05-07T05:09:30+00:00

tt-mode closes switch_pipes in exit_thread_tt and kills processes in
switch_to_tt, if the exit_state is EXIT_DEAD or EXIT_ZOMBIE.

In very rare cases the exiting process can be scheduled out after having set
exit_state and closed switch_pipes (from release_task it calls proc_pid_flush,
which might sleep).  If this process is to be restarted, UML failes in
switch_to_tt with:

   write of switch_pipe failed, err = 9

We fix this by closing switch_pipes not in exit_thread_tt, but later in
release_thread_tt.  Additionally, we set switch_pipe[0] = 0 after closing.
switch_to_tt must not kill "from" process depending on its exit_state, but
must kill it after release_thread was processed only, so it examines
switch_pipe[0] for its decision.

[PATCH] uml: S390 preparation, arch_align_stack

2005-05-07T05:09:30+00:00

Only x86 and x86_64 use arch_align_stack(), all other subarches have:

 #define arch_align_stack(x) (x)

So, if this definition is found, UML's own arch_align_stack() should be
skipped.
