The new networking hashtable sizing is all bollixed up.  The logic is wrong
and tcp is setting it to the logarithm of what was intended.  Heaven knows.

Fix it up so that the sizing is the same as it used to be in 2.6, with a
boot-time override.  Which was what was intended.

From: Kurt Garloff <garloff@suse.de>

when calling

alarm(1); alarm(0);

the second alarm can wrongly return 2. This makes an LSB test fail.

It happens due to rounding errors in the timeval to jiffie conversion and
back.  On i386 with HZ =3D=3D 1000, there would not need to be rounding
error IMVHO, but they even occur there.  On HZ=3D1024 platforms, they may
even be unavoidable.

Attached patch fixes the return value of alarm().

This patch implements what we discussed earlier to fix the switch bewteen
KD_GRAPHICS and KD_TEXT.

It has been tested for a few days now and appear to resolve the problem for
affected users.

James: I know you have some objections, I don't fully agree with them, and
I want that in asap now, that bug has been plaguing fbdev since the very
beginning and it's time to get rid of that and my corresponding todolist
entry.  You are welcome to propose a patch on top of this one if you feel
you can make things cleaner.  The approach of adding a parameter to
con_blank() is Linus idea btw :)

I didn't add a separate function as that would have made the butchering of

The following patches fixes tty drivers which dont set devfs_name. Not
doing so will cause the tty layer to create "/dev/<NULL>x" entries when
devfs is being used.

I used "drivername/" in isicom and pcxe because the letter used to
identify them are already used by other drivers.

The patch below fixes a bug in the error handling code of

This is probably useless on x86 for eg..  (Everything else in this file is

From: "Ronald S. Bultje" <rbultje@ronald.bitfreak.net>

Fix the zoran driver (zr36067) for the fact that we did not handle
bitrate-conversion at all in the zr36050 MJPEG codec (on DC30 cards), with
the result being that at high-resolution, we'd overload the PCI bus and
drop half of our video capture data into /dev/null'ishness.

Also update Ronald's email address in MAINTAINERS.

It appears that gdb, perfmon and perhaps other applications are already
opening /proc/<tid> even though it does not appear in /proc readdir output
and is available under its group leader's directory anyway.

Apparently ascertaining the group leader is hard for gdb and thsi trick
always worked for LinuxThreads apps.

So revert this change.

We should copy the bvec array for read requests so that we still

From: Christophe Saout <christophe@saout.de>

These are some dm-crypt cleanups.  Use a #define PFX "crypt: " for all the
places where something gets logged as suggested by Jeff Garzik.  It also
adds a small additional security check and fixed header includes.

From: Christophe Saout <christophe@saout.de>

This patch fixes the bug where in-place encryption was not detected when
the same highmem pages is mapped twice to different virtual addresses.

This adds a parameter to xxx_process to indicate whether this is an
in-place encryption and moves the responsability to the caller using a
helper function scatterwalk.h.

From: Christophe Saout <christophe@saout.de>

I've cleaned up the latest patches and adjusted the header files.

This patch moves the scatterwalk functions from cipher.c to
scatterwalk.c and adds a header file.

From: Christophe Saout <christophe@saout.de>

__end_that_request_first might modify the bv_offset and bv_len if the
segment was partially completed.  The bio-read-bounce-back code should use
the unmodified bv_offset when copying the segment data:

sysrq-o is supposed to power off the machine.  But if it calls into ACPI (at

This patch updates the g5_defconfig on ppc64, running it through oldconfig

virtual disk probing code.

From: Benjamin Herrenschmidt <benh@kernel.crashing.org>

iSeries HyperVisor is doing some evilery when inserting PTEs that I didn't
properly account for when rewriting that code, causing iSeries box to blow
up regulary.

address_spaces have a `dirtied_when' jiffies field which records the time at
which the mapping was first dirtied.  This is used for the periodic writeback
(kupdate) function.  It is also used to prevent livelocks in the writeback
code: don't try to write back objects which were dirtied after
sync_sb_inodes() was called.

It used to be the case that dirtied_when == 0 had magical properties, so
there is code in there which avoids accidentally setting dirtied_when to zero
at jiffy wrap time.  We just set it to jiffies|1.

Unfortunately, jiffies|1 is in the future.  So under some rare timing
circumstances (inode dirtied within one jiffy of umount) the livelock
avoidance code in sync_sb_inodes() can accidentally trigger and we fail to
write an inode out, resulting in filesytem corruption on ext2-style
filesystems.  Normally, nobody dirties a file within a millisecond of umount,
so it was not noticed.

It is no longer the case that (address_space.dirtied_when == 0) has special
meaning, so we can just remove all that code and fix the bug.

This fixes the PowerPC Virtual Ethernet driver that got broken by the
recent ppc64 iommu patch...

This patch seems to have been forgotten about, so here it is again,
this time against 2.6.4-rc1.  This really needs to be send upstream,
though I don't know where we got to with this one.  Maybe we should
put it in akpm's tree for a while?

It's essentially more of the "don't deadlock if you pull out a
PCMCIA network card and it's currently configured up" patch which
went in recently for PCMCIA NIC cards.

Note that hp100 in 2.6.4-rc1 is still broken wrt EISA probing, since
it lacks the terminating entry in the EISA ID list. This one-liner
should take care of random crashes that are often reported to LKML :

To hotplug-remove virtual devices, we need vio_find_node() so we have a

vio_dev->unit_address only holds 32 bits of information anyways, so no
need for 64-bit field.
