only allow specific type-3 packets to pass the verifier instead of all for r100/r200 as others might be unsafe (r300 already does this), and add checking for these we need but aren't safe. Check the RADEON_CP_INDX_BUFFER packet on both r200 and r300 as it isn't safe neither.

The iTCO_wdt.c driver has been tested enough. So we can

The new Atmel AT91SAM9261 and AT91SAM9260 processors use a different
internal watchdog peripheral. This watchdog driver is therefore
AT91RM9200-specific.
This patch renames at91_wdt.c to at91rm9200_wdt.c, and changes the name
of the configuration option.

gcc emits the following warning:
drivers/char/watchdog/iTCO_wdt.c: In function ‘iTCO_wdt_ioctl’:
drivers/char/watchdog/iTCO_wdt.c:429: warning: ‘time_left’ may be used uninitialized in this function
This indicates a condition near enough to a bug, to want to fix.
iTCO_wdt_get_timeleft() stores a value in 'time_left' iff
iTCO_version==(1 or 2). This driver only supports versions
1 or 2, so this is ok. However, since (a) the return value of
iTCO_wdt_get_timeleft() is handled anyway, (b) it fixes the warning,
and (c) it future-proofs the driver, we go ahead and add the obvious
return value.

This is patch 16 in the series of patches that converts
Marcus Junker's w83697hf watchdog driver to Samuel Tardieau's
w83697hf/hg watchdog driver.
This patch contains following changes:
- Add copyright notice for Samuel Tardieu also.
This is the last patch in this series.
The original description for Samuel's driver was:
driver for the Winbond W83697HF/W83697HG watchdog timer
The Winbond SuperIO W83697HF/HG includes a watchdog that can count from
1 to 255 seconds (or minutes). This drivers allows the seconds mode to
be used. It exposes a standard /dev/watchdog interface. This chip is
currently being used on some motherboards designed by VIA.
By default, the module looks for a chip at I/O port 0x2e. The chip can
be configured to be at 0x4e on some motherboards, the address can be
chosen using the wdt_io module parameter. Using 0 will try to autodetect
the address.

This is patch 15 in the series of patches that converts
Marcus Junker's w83697hf watchdog driver to Samuel Tardieau's
w83697hf/hg watchdog driver.
This patch contains following changes:
- Clean-up initialization code - part 2:
* the line reading "set second mode & disable keyboard ..."
is plain wrong, the register being manipulated (CRF4) is
the counter itself, not the control byte (CRF3) -- looks
like it has been copied from another driver.
* I think garbage is being written in CRF3 (the control word)
as the timeout value is being stored in this register (such
as 60 for 60 seconds).
* We only want to set pin 119 to WDTO# mode and leave the rest
of CR29 like it is.
* Set count mode to seconds and not minutes.

| | |

| | |
| | |
| | | |
In contrast to most if not all PC BIOSes, OpenFirmware (OF) on PowerMacs with
UniNorth bridges does not allow changing the aperture size. The size set up by
OF is usually 16 MB, which is too low for graphics intensive environments.
Hence, add a module parameter that allows changing the aperture size at driver
initialization time. When the parameter is not specified, the default is 32 MB.

efe1ec27837d6639eae82e1f5876910ba6433c3f corrects pci device matching in
only one way; it no longer oopses/crashes, despite hotplug is not solved
in these changes.
Whenever pci_find_device -> pci_get_device change is performed, also
pci_dev_get and pci_dev_put should be in most cases called to properly
handle hotplug. This patch does exactly this thing -- increase refcount
to let kernel know, that we are using this piece of HW just now.
It affects moxa and rio char drivers.
