This patch does a full cleanup of 'NULL checks before vfree', and a partial
cleanup of calls to kfree for all of drivers/ - the kfree bit is partial in
that I only did the files that also had vfree calls in them. The patch
also gets rid of some redundant (void *) casts of pointers being passed to
[vk]free, and a some tiny whitespace corrections also crept in.Signed-off-by: Jesper Juhl

On a vc resize, the contents of the old screen buffer are transferred to the
new screenbuffer. If the new screenbuffer is smaller than the old one, only
the contents from the bottom are copied to new. If the contents of the old
buffer are located at the top, then the contents will not be copied to the new
buffer resulting in a blank screen.This bug will happen only if the vc in question is not in the foreground.
Doing an fbset -a or con2fbmap will trigger this bug.To fix this problem, base the start of the copy from the location of the
current cursor. If the cursor is near the top of the buffer, copy the
contents at the top, and if the cursor is near the bottom of the buffer, then
copy the contents at the bottom. In the unlikely case where the new row size
is greater than 2x smaller than the old one, and the cursor is in the middle,
copy 1/2 screenful from the top and bottom of the cursor position.Signed-off-by: Antonino Daplas

With the use of RCU in files structure, the look-up of files using fds can now

In order for the RCU to work, the file table array, sets and their sizes must
be updated atomically. Instead of ensuring this through too many memory
barriers, we put the arrays and their sizes in a separate structure. This
patch takes the first step of putting the file table elements in a separate
structure fdtable that is embedded withing files_struct. It also changes all
the users to refer to the file table using files_fdtable() macro. Subsequent
applciation of RCU becomes easier after this.Signed-off-by: Dipankar Sarma

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.

The IPMI power control function proc_write_chassctrl was badly written, it
directly used userspace pointers, it assumed that strings were NULL
terminated, and it used the evil sscanf function. This converts over to
using the sysctl interface for this data and changes the semantics to be a
little more logical.Signed-off-by: Corey Minyard

This patch allows Dell servers with IPMI controllers that predate IPMI 1.5
to use the standard poweroff or powercycle commands. These systems
firmware don't set the chassis capability bit in the Get Device ID, but
they do implement the standard poweroff and powercycle commands.Tested on RHEL3 kernel 2.4.21-20.ELsmp on a PowerEdge 2600. The standard
ipmi_poweroff driver cannot drive these systems. With this patch, they
power off or powercycle as expected.Signed-off-by: Matt Domsch

The "null message handler" in the IPMI driver is used in startup and panic
situations to handle messages. It was only designed to work with messages
from the local management controller, but in some cases it was used to get
messages from remote managmenet controllers, and the system would then
panic. This patch makes the "null message handler" in the IPMI driver more
general so it works with any kind of message.Signed-off-by: Corey Minyard

The ipmi driver does not have a way to handle firmware-generated events
which have the OEM[012] Data Available flags set. In such a case, the
SMS_ATN bit may never get cleared by firmware, leaving the driver looping
infinitely but never able to make any progress.This patch first simplifies storage and use of the data returned from an
IPMI Get Device ID command.It then creates a new per-OEM handler hook, which should know how to handle
events with the OEM[012] Data Available flags set. It then uses this to
implement a workaround for IPMI 1.5-capable Dell PowerEdge servers which
are susceptable to setting the OEM[012] Data Available flags when the
driver can't handle it.Signed-off-by: Matt Domsch

IPMI allows multiple IPMB channels on a single interface, and each channel
might have a different IPMB address. However, the driver has only one IPMB
address that it uses for everything. This patch adds new IOCTLS and a new
internal interface for setting per-channel IPMB addresses and LUNs. New
systems are coming out with support for multiple IPMB channels, and they are
broken without this patch.Signed-off-by: Corey Minyard
