If a page can't be allocated for the frag list of a skb, the code to

'frags' equals one, i == 0, and the alloc_page() fails, then the old

The PCI-ID 1183 is SATA in PATA-emulation, but not fully compatible

Recently the PLL input clock of pata_pdc2027x is sometimes detected
higer than expected (e.g. 20.027 MHz compared to 16.714 MHz).
It seems sometimes the mdelay() function is not as precise as it
used to be. Per Alan's advice, HT or power management might affect
the precision of mdelay().
This patch calls gettimeofday() to mesure the time elapsed and

If asus_acpi_init doesn't find any device it knows about, it mistakenly
returns a "success" error code even though it cleans up after itself. Later
when trying to rmmod asus_acpi, the module_exit routine would try to clean up
one more time and we would end up calling
acpi_bus_unregister_driver(&asus_hotk_driver) twice. This patch addresses
this first problem by returning -ENODEV when no appropriate device is found.
Then there was also another bug with the code handling the return value of
backlight_device_register. If this function ever failed, the driver would
cleanup by calling the module_exit routine from module_init, but it would
still return "success". So any attempt to rmmod this module would result in
asus_acpi_exit being called twice but it's not ready to handle it (I haven't
hit this bug, just found it by code inspection). This patch fixes that by
inserting a return -ENODEV; at the end of this error handling path.

This patch changes the test for the thread pid from >= 0 to > 0.
When the saa8134 driver initialization fails after a certain point, it goes
through the complete shutdown process for the driver. Part of shutting it
down includes tearing down the thread for tv audio.
The test for tearing down the thread tests for >= 0. Since the dev
structure is kzalloc'd, the test will always be true if we haven't tried to
start the thread yet. We end up waiting on pid 0 to complete, which will
never happen, so we lock up.

If one has a dependency chain (tristate)FOO depends on (bool)BAR depends on
(tristate)BAZ, build problems will result. If BAZ=m, then BAR can be set
y, which allows FOO=y. It's possible to have FOO=y && BAZ=m, which
wouldn't be allowed if FOO depended directly on BAZ. In effect, the bool
promotes the tristate from m to y.
This ends up causing a problem with several menuconfigs that look like:
menuconfig BAR
bool
depends on BAZ [tristate]
if BAR
config FOO
tristate
endif
The solution used here is to add the dependencies of BAR to the if
statement, so that items in the if block will gain a direct
non-bool-promoted dependency on BAZ. This is how it would work if a menu
was used instead of an if block.

Some HP firmware leaves the SMCf010 IRDA device incompletely configured, or
reports the wrong resources in _CRS. As a workaround, when we find such a
device, try to auto-configure the device.
This ignores the _CRS data, picks a config from _PRS, and runs _SRS to
configure the device. This makes smsc-ircc2 work correctly with PNP
resources (with no preconfiguration!) on all the machines I tested.
I think Windows does something like this by default for all devices,
so we should consider doing the same thing in Linux.
This patch addresses part of the 2.6.22 regression:
"no irda0 interface (2.6.21 was OK), smsc does not find chip"

usb_unlink_urb() is asynchronous, therefore an URB's buffer may not
be freed without waiting for the completion handler. This patch switches
to usb_kill_urb(), which is synchronous.

Recently my console UTF-8 patch went mainline. Here is an additional patch
that fixes two nasty issues and improves a third one, namely:
1. My patch changed the behavior if a glyph is not found in the Unicode
mapping table. Previously for Unicode values less than 256 or 512 the
kernel tried to display the glyph from that position of the glyph table,
which could lead to a different accented letter being displayed. I
removed this fallback possibility and changed it to display the
replacement symbol.
As Behdad pointed out, some fonts (e.g. sun12x22 from the kbd package)
lack Unicode mapping information, hence all you get is lots of question
marks. Though theoretically it's actually a user-space bug (the font
should be fixed), Behdad and I both believe that it'd be good to work
around in the kernel by re-introducing the fallback solution for ASCII
characters only. This sounds a quite reasonable decision, since all fonts
ship the ASCII characters in the first 128 positions. This way users
won't be surprised by lots of question marks just because s/he issued a
not-so-perfectly parameterized setfont command. As this fallback is only
re-introduced for code points below 128, you still won't see an accented
letter replaced by another, but at least you'll always get the English
letters right.
2. My patch introduced "question mark with inverted color attributes" as a
last resort fallback glyph. Though it perfectly works on VGA console, on
framebuffer you may end up with question marks that are highlighed but
shouldn't be, and normal characters that are accidentally highlighed.
This is caused by missing FLUSHes when changing the color attribute.
3. I've updated the table of double-width character based on Markus's
updated version. Only ten new code poings (one interval) is added.

Always disable/enable interrupts in the acpi idle routine,
even in the error path.
This is required as the 2.6.20 change in git commit d331e739f5ad2aaa9...
"Fix interrupt race in idle callback" expects the idle handler
to enable interrupt before returning.
There was a case in acpi idle routine, in which interrupt was not being
enabled before return, which caused the system to hang at bootup, while
enabling C-states on an SMP system.
The signature of the hang was that "processor.nocst"
was required to enable boot.
