This patch adds support for Dynamic Tick Timer for ARM. Dynamic Tick is also known as VST (Variable Scheduling Timeouts). Dynamic Tick has been in use in the OMAP tree since last October. The patch is not intrusive, and does not do anything unless CONFIG_NO_IDLE_HZ is defined. This patch has the following fixed based on comments from RMK: - Time is updated before calling interrupt handlers. - Added new interrupt flag SA_TIMER to avoid duplicate timer interrupts - Moved struct dyn_tick_timer to time.h until we at some point probably have an arch independent dyn-tick.h - Cleaned up testing for DYN_TICK_ENABLED in irq.c I've cleaned up this patch to fix some remaining issues: - Call the timer tick handler with irqs disabled, as it would be from a normal interrupt - if we have a dyn_tick, we better implement all methods. - generic timer_dyn_reprogram() call, to be called before sleeping - added command line option - "dyntick=" to allow boot-time control of this feature -- rmk Signed-off-by: Tony Lindgren Signed-off-by:Russell King <rmk+kernel@arm.linux.org.uk>

Patch from Lennert Buytenhek The later ixp2000 models don't need the PCI I/O workaround that we currently perform. Add a config option to disable the workaround, and panic on boot if a kernel without the workaround is booted on a buggy chip. As only pre-production ixp2000s need the workaround, the default is for it not to be configured in. Signed-off-by:

Patch from Lennert Buytenhek The ixp2000 gpio cleanup broke the ixdp2800 build as it moved some gpio-related functions from arch/platform.h to arch/gpio.h and the ixdp2x00 support code used those functions but didn't include the latter header file. Signed-off-by:

Patch from Lennert Buytenhek On the enp2611, GPIO 7 and 6 are connected to an on-board i2c bus that attaches to the SODIMM module slot (for SPD) and an LM84 temperature sensor. Add a platform device for this i2c bus. Signed-off-by:

Patch from Lennert Buytenhek A number of ixp2000 models have a bug where the byte lanes for PCI I/O transactions are swapped. We already work around this in our versions of {in,out}{b,w,l}, but we also need to perform these workarounds in a custom implementation of the new iomap API, provided in this patch. Signed-off-by: -

Patch from Lennert Buytenhek This patch conditionalises the io{read,write}{8,16,32} defines and the prototypes for ioport_map/ioport_unmap in asm-arm/io.h on ioread8 not already having been defined. This is done so that platforms can provide their own implementation of the iomap API, ixp2000 for example needs this. Signed-off-by: -

Patch from Catalin Marinas cpu_v6_set_pte() sets the kernel access rights to r/o for user pages (L_PTE_USER) when neither L_PTE_WRITE nor L_PTE_DIRTY are set. This causes a kernel data abort when writing the TLS value in the 0xffff0000 page. This patch enables the kernel r/w access. Signed-off-by: Catalin Marinas Signed-off-by: -

Patch from Deepak Saxena Current IXP4xx debug macros do not work in the small window between the MMU being enabled and the call to map_io() b/c the standard peripheral mapping is not properly setup for use with the low-level debug code.

Patch from Lennert Buytenhek This patch cleans up the ixp2000 gpio irq code and implements the set_irq_type method for gpio irqs so that users can select for which events (falling edge/rising edge/level low/level high) on the gpio pin they want the corresponding gpio irq to be triggered.

They don't actually clobber memory, but gcc doesn't even know they _read_ memory, so can apparently re-order memory accesses around them. Which obviously does the wrong thing if the memory access happens to change the memory that the compare function is accessing.. Verified to fix a strange boot problem by Jens Axboe.

Carsten Otte authored
This patch reworks filemap_xip.c with the goal to reduce code duplication from mm/filemap.c. It applies agains 2.6.12-rc6-mm1. Instead of implementing the aio functions, this one implements the synchronous read/write functions only. For readv and writev, the generic fallback is used. For aio, we rely on the application doing the fallback. Since our "synchronous" function does memcpy immediately anyway, there is no performance difference between using the fallbacks or implementing each operation. Signed-off-by:

Carsten Otte authored
- generic_file* file operations do no longer have a xip/non-xip split - filemap_xip.c implements a new set of fops that require get_xip_page aop to work proper. all new fops are exported GPL-only (don't like to see whatever code use those except GPL modules) - __xip_unmap now uses page_check_address, which is no longer static in rmap.c, and defined in linux/rmap.h - mm/filemap.h is now much more clean, plainly having just Linus' inline funcs moved here from filemap.c - fix includes in filemap_xip to make it build cleanly on i386 Signed-off-by:

This patch adds version and srcversion files to /sys/module/${modulename} containing the version and srcversion fields of the module's modinfo section (if present). /sys/module/e1000 |-- srcversion `-- version This patch differs slightly from the version posted in January, as it now uses the new kstrdup() call in -mm. Why put this in sysfs? a) Tools like DKMS, which deal with changing out individual kernel modules without replacing the whole kernel, can behave smarter if they can tell the version of a given module. The autoinstaller feature, for example, which determines if your system has a "good" version of a driver (i.e. if the one provided by DKMS has a newer verson than that provided by the kernel package installed), and to automatically compile and install a newer version if DKMS has it but your kernel doesn't yet have that version. b) Because sysadmins manually, or with tools like DKMS, can switch out modules on the file system, you can't count on 'modinfo foo.ko', which looks at /lib/modules/${kernelver}/... actually matching what is loaded into the kernel already. Hence asking sysfs for this. c) as the unbind-driver-from-device work takes shape, it will be possible to rebind a driver that's built-in (no .ko to modinfo for the version) to a newly loaded module. sysfs will have the currently-built-in version info, for comparison. d) tech support scripts can then easily grab the version info for what's running presently - a question I get often. There has been renewed interest in this patch on linux-scsi by driver authors. As the idea originated from GregKH, I leave his Signed-off-by: intact, though the implementation is nearly completely new. Compiled and run on x86 and x86_64.

Even though it says DViCO FusionHDTV3 Gold-Q on the box, Gold-T is printed on the card. This fix corrects the error in all places, and corrects the tuner name Thomson DDT 7611 (ATSC/NTSC) in the documentation. This applies against 2.6.12-rc5-mm2 after applying Manueal Capinha's patch "Add support for PixelView Ultra Pro in v4l" (because of the change from card=27 to card=28) Signed-off-by:

The following patch adds support for the PixelView Ultra Pro video capture card in v4l. - It removes the remote control key definitions from ir-kbd-gpio.c and moves them to ir-common.c so that they can be shared between bt878 and cx88 based cards. - The patch also moves the FUSIONHDTV_3_GOLD_Q card from number 27 to 28 to regain compatibility with the V4L cvs. Signed-off-by:
