59f4e7d572 [PATCH] fix reboot via keyboard controller reset
I have a system (Biostar IDEQ210M mini-pc with a VIA chipset) which will
not reboot unless a keyboard is plugged in to it.  I have tried all
combinations of the kernel "reboot=x,y" flags to no avail.  Rebooting by
any method will leave the system in a wedged state (at the "Restarting
system" message).

I finally tracked the problem down to the machine's refusal to fully reboot
unless the keyboard controller status register had bit 2 set.  This is the
"System flag" which when set, indicates successful completion of the
keyboard controller self-test (Basic Assurance Test, BAT).

I suppose that something is trying to protect against sporadic reboots
unless the keyboard controller is in a good state (a keyboard is present),
but I need this machine to be headless.

I found that setting the system flag (via the command byte) before giving
the "pulse reset line" command will allow the reboot to proceed.  The patch
is simple, and I think it should be fine for everybody whether they have
this type of machine or not.  This affects the "hard" reboot (as done when
the kernel boot flags "reboot=c,h" are used).

Also, make the cancellation path lock the kiocb and subsequently release
all references to it if the cancel was successful.  This version includes a
fix for the deadlock with __aio_run_iocbs.

# cp 60k-archive.zip /mnt/mt.zip

# rm /mnt/mt.zip

 [If the unlink happens before the buffers flush, the following happens:]

383f2835eb [PATCH] Prefetch kernel stacks to speed up context switch
For architecture like ia64, the switch stack structure is fairly large
(currently 528 bytes).  For context switch intensive application, we found
that significant amount of cache misses occurs in switch_to() function.
The following patch adds a hook in the schedule() function to prefetch
switch stack structure as soon as 'next' task is determined.  This allows
maximum overlap in prefetch cache lines for that structure.

b0d62e6d5b [PATCH] fix disassociate_ctty vs. fork race
Race is as follows. Process A forks process B, both being part of the same
session. Then, A calls disassociate_ctty while B forks C:

A				B
====				====
				fork()
				  copy_signal()
dissasociate_ctty()		....
				  attach_pid(p, PIDTYPE_SID, p->signal->session);

Now, C can have current->signal->tty pointing to a freed tty structure, as
it hasn't yet been added to the session group (to have its controlling tty
cleared on the diassociate_ctty() call).

This has shown up as an oops but could be even more serious.  I haven't
tried to create a test case, but a customer has verified that the patch
below resolves the issue, which was occuring quite frequently.  I'll try
and post the test case if i can.

The patch simply checks for a NULL tty *after* it has been attached to the
proper session group and clears it as necessary.  Alternatively, we could
simply do the tty assignment after the the process is added to the proper
session group.

28254d439b [PATCH] vga text console and stty cols/rows
Some people use 66-cells braille devices for reading the console, and hence
would like to reduce the width of the screen by using:

stty cols 66

However, the vga text console doesn't behave correctly: the 14 first
characters of the second line are put on the right of the first line and so
forth.

Here is a patch to correct that.  It corrects the disp_end and offset
registers of the vga board on console resize and console switch.

On usual screens, you then correctly get a right and/or bottom blank
margin.  On some laptop panels, the output is resized so that text actually
gets magnified, which can be great for some people (see
http://dept-info.labri.fr/~thibault/ls.jpg ).

ff55fe2075 [PATCH] pty_chars_in_buffer oops fix
The idea of this patch is to lock both sides of a ptmx/pty pair during line
discipline changing.  This is needed to ensure that say a poll on one side of
the pty doesn't occur while the line discipline is actively being changed.
This resulted in an oops reported on lkml, see:

	http://marc.theaimsgroup.com/?l=linux-kernel&m=111342171410005&w=2

A 'hacky' approach was previously implmemented which served to eliminate the
poll vs.  line discipline changing race.  However, this patch takes a more
general approach to the issue.  The patch only adds locking on a less often
used path, the line-discipline changing path, as opposed to locking the
ptmx/pty pair on read/write/poll paths.

The patch below, takes both ldisc locks in either order b/c the locks are both
taken under the same spinlock().  I thought about locking the ptmx/pty
separately, such as master always first but that introduces a 3 way deadlock.
For example, process 1 does a blocking read on the slave side.  Then, process
2 does an ldisc change on the slave side, which acquires the master ldisc lock
but not the slave's.  Finally, process 3 does a write which blocks on the
process 2's ldisc reference.

This patch does introduce some changes in semantics.  For example, a line
discipline change on side 'a' of a ptmx/pty pair, will now wait for a
read/write to complete on the other side, or side 'b'.  The current behavior
is to simply wait for any read/writes on only side 'a', not both sides 'a' and
'b'.  I think this behavior makes sense, but I wanted to point it out.

I've tested the patch with a bunch of read/write/poll while changing the line
discipline out from underneath.

This patch obviates the need for the above "hide the problem" patch.

69ac59647e [PATCH] alpha: process_reloc_for_got confuses r_offset and r_addend
arch/alpha/kernel/module.c:process_reloc_for_got(), which figures out how big
the .got section for a module should be, appears to be confusing r_offset (the
file offset that the relocation needs to be applied to) with r_addend (the
offset of the relocation's actual target address from the address of the
relocation's symbol).  Because of this, one .got entry is allocated for each
relocation instead of one each unique symbol/addend.

In the module I am working with, this causes the .got section to be almost 10
times larger than it needs to be (75544 bytes instead of 7608 bytes).  As the
.got is accessed with global-pointer-relative instructions, it needs to be
within the 64k gp "zone", and a 75544 byte .got clearly does not fit.  The
result of this is that relocation overflows are detected during module load
and the load is aborted.

Change struct got_entry/process_reloc_for_got to fix this.

092c948811 [PATCH] x86_64: Don't call enforce_max_cpus when hotplug is enabled
enforce_max_cpus nukes out cpu_present_map and cpu_possible_map making it
impossible to add new cpus in the system.  Since it doesnt provide any
additional value apart this call and reference is removed.

fdf26d933a [PATCH] x86_64: Don't do broadcast IPIs when hotplug is enabled in flat mode.
The use of non-shortcut version of routines breaking CPU hotplug.  The option
to select this via cmdline also is deleted with the physflat patch, hence
directly placing this code under CONFIG_HOTPLUG_CPU.

We dont want to use broadcast mode IPI's when hotplug is enabled.  This causes
bad effects in send IPI to a cpu that is offline which can trip when the cpu
is in the process of being kicked alive.

4c7fc7220f [PATCH] i386: seccomp fix for auditing/ptrace
This is the same issue as ppc64 before, when returning to userland we
shouldn't re-compute the seccomp check or the task could be killed during
sigreturn when orig_eax is overwritten by the sigreturn syscall.  This was
found by Roland.

This was harmless from a security standpoint, but some i686 users reported
failures with auditing enabled system wide (some distro surprisingly makes
it the default) and I reproduced it too by keeping the whole workload under
strace -f.

Patch is tested and works for me under strace -f.

nobody@athlon:~/cpushare> strace -o /tmp/o -f python seccomp_test.py

95409aaca7 [PATCH] ppc32: Kill PVR_440* defines
The following patch changes the usages of PVR_440* into strcmp's with the
cpu_name field, and removes the defines altogether.  The Ebony portion was
briefly tested long ago.  One benefit of moving from PVR-tests to string
tests in general is that not all CPUs can be on and be able to do this type
of comparison.

See http://patchwork.ozlabs.org/linuxppc/patch?id=1250 for the original

66b375bf7d [PATCH] ppc32: In the boot code, don't rely on BASE_BAUD directly
Modifies serial_init to get base baud rate from the rs_table entry instead
of BAUD_BASE.  This patch eliminates duplication between the
SERIAL_PORT_DFNS macro and BAUD_BASE.  Without the patch, if a port set the
baud rate in SERIAL_PORT_DFNS, but did not update BASE_BAUD, the BASE_BAUD
value would still be used.
