7ed20e1ad5 [PATCH] convert that currently tests _NSIG directly to use valid_signal()
Convert most of the current code that uses _NSIG directly to instead use
valid_signal().  This avoids gcc -W warnings and off-by-one errors.

e5bdd883a1 [PATCH] new valid_signal() function
This patch adds a new function valid_signal() that tests if its argument is
a valid signal number.

The reasons for adding this new function are:

- some code currently testing _NSIG directly has off-by-one errors.
  Using this function instead avoids such errors.

- some code currently tests unsigned signal numbers for <0 which is
  pointless and generates warnings when building with gcc -W.  Using this
  function instead avoids such warnings.

I considered various places to add this function but eventually settled on
include/linux/signal.h as the most logical place for it.  If there's some
reason this is a bad choice then please let me know (hints as to a better
location are then welcome of course).

9dbf68f97d [PATCH] ipmi: enable interrupts on the BT driver
Enable interrupts for a BT interface.  There is a specific register that
needs to be set up to enable interrupts that also must be modified to clear
the irq.

Also, don't reset the BMC on a BT interface.  That's probably not a good
idea as the BMC may be performing other important functions and a reset
should only be a last resort.  Also, that register is also used to
enable/disable interrupts to the BT; modifying it may screw up the
interrupts.

e49332bd12 [PATCH] misc verify_area cleanups
There were still a few comments left refering to verify_area, and two
functions, verify_area_skas & verify_area_tt that just wrap corresponding
access_ok_skas & access_ok_tt functions, just like verify_area does for
access_ok - deprecate those.

There was also a few places that still used verify_area in commented-out
code, fix those up to use access_ok.

After applying this one there should not be anything left but finally
removing verify_area completely, which will happen after a kernel release
or two.

a40920b42a [PATCH] vgacon: set vc_hi_font_mask correctly
When allocating a new VC with vgacon_init(), the font is shared across all
the VGA consoles.  However, the font mask was always set to the default
value of zero in visual_init(), even if we were using 512 character fonts
at the time.

Moreover, code in vgacon.c:vga_do_font_op() didn't reset the mask if the
console driver thinks it's already in 512 character mode.  This means that
to *fix* it, you'd actually have to take the console out of 512 character
mode and then set it back.

The attached sets vc_hi_font_mask in vgacon_init() for any new consoles
opened if the vgacon driver is already in 512 character mode, solving this.

This bug goes back to 2.4.18 at least, probably earlier.

6c9e7376be [PATCH] LifeView FlyTV Platinum FM: GPIO usage
This is take two of a patch that should have appeared two days ago, before
yesterday's "remote control" patch for the same card.

This patch sets unconnected GPIO to Output to keep them from floating (just
good driver writing practice, being nice to the chip), and uses GPIO16 to
switch TV vs.  FM - this pin switches inputs onto the tuner, as well as the
audio output from the tuner into the 7135 SIF input.  Consequently, FM
radio support is being un-commented because it's now working (sort of, see
below).

These two patches get the card almost fully operational; there appears to
be a bug in tda8290.c remaining that puts an offset onto the tuned
frequency in FM radio mode.  We're investigating.

9a3bb30173 [PATCH] reiserfs: make resize option auto-get new device size
It's trivial for the resize option to auto-get the underlying device size,
while it's harder for the user.  I've copied the code from jfs.

Since of the different reiserfs option parser (which does not use the
superior match_token used by almost every other filesystem), I've had to
use the "resize=auto" and not "resize" option to specify this behaviour.
Changing the option parser to the kernel one wouldn't be bad but I've no
time to do this cleanup in this moment.

Btw, the mount(8) man page should be updated to include this option.  Cc
the relevant people, please (I hope I cc'ed the right people).

9b06e81898 [PATCH] Deprecate synchronize_kernel, GPL replacement
The synchronize_kernel() primitive is used for quite a few different purposes:
waiting for RCU readers, waiting for NMIs, waiting for interrupts, and so on.
This makes RCU code harder to read, since synchronize_kernel() might or might
not have matching rcu_read_lock()s.  This patch creates a new
synchronize_rcu() that is to be used for RCU readers and a new
synchronize_sched() that is used for the rest.  These two new primitives
currently have the same implementation, but this is might well change with
additional real-time support.  Both new primitives are GPL-only, the old
primitive is deprecated.

See below for a patch that puts the exports back, along with an updated

I will also be following this message with RFC patches that introduce two
(EXPORT_SYMBOL_GPL) interfaces to replace synchronize_kernel(), which then
becomes deprecated.

still left per-arch.

Right now, adding a new IRQ flag to the arch-specific header, like this
patch does:
http://cvs.sourceforge.net/viewcvs.py/*checkout*/alsa/alsa-driver/utils/patches/pcsp-kernel-2.6.10-03.diff?rev=1.1
no longer works, it breaks the compilation for all other arches, unless you
add that flag to all the other arch-specific headers too.  So I think such
a clean-up makes sense.

The patch implements a simple rlimit ceiling for the RT (and nice) priorities

default.  A value of 50 means RT priority levels 1-50 are allowed.  A value of
100 means all 99 privilege levels from 1 to 99 are allowed.  CAP_SYS_NICE is
blanket permission.

ec5883abeb [PATCH] s390: don't pad cdl blocks for write requests
The first blocks on a cdl formatted dasd device are smaller than the blocksize
of the device.  Read requests are padded with a 'e5' pattern.  Write requests
should not pad the (user) buffer with 'e5' because a write request is not
allowed to modify the buffer.

6ed93c827e [PATCH] s390: enable write barriers in the dasd driver
The DASD device driver never reorders the I/O requests and relies on the
hardware to write all data to nonvolatile storage before signaling a
successful write.  Hence, the only thing we have to do to support write
barriers is to set the queue ordered flag.

f24acd4503 [PATCH] s390: dasd readonly attribute
The independent read-only flags in devmap, dasd_device and gendisk are not
kept in sync.  Use one bit per feature in the dasd driver and keep that bit in
sync with the gendisk bit.

15439d74f6 [PATCH] s390: cmm guest sender id
An arbitrary guest must not be allowed to trigger cmm actions.  Only one
specific guest namely the one that serves as the resource monitor may send cmm
messages.  Add a parameter that allows to specify the guest that may send
messages.  z/VMs resource manager has the name 'VMRMSVM' which is the default.

c9e3735359 [PATCH] s390: fix memory holes and cleanup setup_arch
The memory setup didn't take care of memory holes and this makes the memory
management think there would be more memory available than there is in
reality.  That causes the OOM killer to kill processes even if there is enough
memory left that can be written to the swap space.

The patch fixes this by using free_area_init_node with an array of memory
holes instead of free_area_init.  Further the patch cleans up the code in
setup.c by splitting setup_arch into smaller pieces.
