[AGPGART] VIA PT880 Ultra support.

2006-09-18T17:17:43+00:00

This patch enables agpgart on a Via "PT880 Ultra" based motherboard
(Asus P4V800D-X). The PCI ID of the PT880 Ultra is 0x0308 instead of
0x0258 of the PT880.

The patched via-agp passes testgart.

ext3: avoid triggering ext3_error on bad NFS file handle

2006-08-30T15:58:44+00:00

The inode number out of an NFS file handle gets passed eventually to
ext3_get_inode_block() without any checking.  If ext3_get_inode_block()
allows it to trigger an error, then bad filehandles can have unpleasant
effect - ext3_error() will usually cause a forced read-only remount, or a
panic if `errors=panic' was used.

So remove the call to ext3_error there and put a matching check in
ext3/namei.c where inode numbers are read off storage.

Andrew Morton fixed an off-by-one error.

Dann Frazier ported the patch to 2.6.16.

[PATCH] I2O: Bugfixes to get I2O working again

2006-06-22T19:16:12+00:00

- Fixed locking of struct i2o_exec_wait in Executive-OSM

- Removed LCT Notify in i2o_exec_probe() which caused freeing memory and
  accessing freed memory during first enumeration of I2O devices

- Added missing locking in i2o_exec_lct_notify()

- removed put_device() of I2O controller in i2o_iop_remove() which caused
  the controller structure get freed to early

- Fixed size of mempool in i2o_iop_alloc()

- Fixed access to freed memory in i2o_msg_get()

[PATCH] Simplify proc/devices and fix early termination regression

2006-05-01T19:03:43+00:00

Repair /proc/devices early-termination regression.

2.6.16 broke /proc/devices.  An application often gets an
EOF before the end of data is reached, if that application
uses a series of short read(2)s to access the data.  I have
used read buffers of varying sizes with varying degrees
of unsuccess (larger sizes get further into the data than
smaller sizes, following a simple pattern).  It appears
that the only safe way to get the data is to use a single
read buffer larger than all the data in /proc/devices.

The following example demonstates the problem:

    # dd if=/proc/devices bs=1
    Character devices:
      1 mem
    27+0 records in
    27+0 records out

This patch is a backport of the fix recently accepted to
Linus's tree:

    commit 68eef3b4791572ecb70249c7fb145bb3742dd899
    [PATCH] Simplify proc/devices and fix early termination regression

It replaces the complex, state-machine algorithm introduced
in 2.6.16 with a simple algorithm, modeled on the implementation
of /proc/interrupts.

[PATCH] Fix buddy list race that could lead to page lru list corruptions

2006-04-17T20:16:05+00:00

Rohit found an obscure bug causing buddy list corruption.

page_is_buddy is using a non-atomic test (PagePrivate && page_count == 0)
to determine whether or not a free page's buddy is itself free and in the
buddy lists.

Each of the conjuncts may be true at different times due to unrelated
conditions, so the non-atomic page_is_buddy test may find each conjunct to
be true even if they were not both true at the same time (ie. the page was
not on the buddy lists).

[PATCH] fbcon: Fix big-endian bogosity in slow_imageblit()

2006-04-07T16:44:29+00:00

The monochrome->color expansion routine that handles bitmaps which have
(widths % 8) != 0 (slow_imageblit) produces corrupt characters in big-endian.
This is caused by a bogus bit test in slow_imageblit().

Fix.
