2007-10-16During VM oom condition, kill all threads in process groupWill Schmidt1-1/+1
We have had complaints where a threaded application is left in a bad state after one of it's threads is killed when we hit a VM: out_of_memory condition. Killing just one of the process threads can leave the application in a bad state, whereas killing the entire process group would allow for the application to restart, or be otherwise handled, and makes it very obvious that something has gone wrong. This change allows the entire process group to be taken down, rather than just the one thread.

2007-10-15[ARM] pxa: Avoid pxa_gpio_mode() in gpio_direction_{in,out}put()Russell King1-0/+38
pxa_gpio_mode() is a universal call that fiddles with the GAFR (gpio alternate function register.) GAFR does not exist on PXA3 CPUs, but instead the alternate functions are controlled via the MFP support code. Platforms are expected to configure the MFP according to their needs in their platform support code rather than drivers. We extend this idea to the GAFR, and make the gpio_direction_*() functions purely operate on the GPIO level. This means platform support code is entirely responsible for configuring the GPIOs alternate functions on all PXA CPU types. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2007-10-12[ARM] 4600/1: fix kernel build failure with build-id-supporting binutilsLennert Buytenhek1-1/+1
Newer versions of binutils support --build-id, which adds an ELF note section called ".note.gnu.build-id" to the output. On the ARM kernel build, because there is no explicit mention of this section in the shipped ld script, this section is placed at vaddr 0x00000000 (whereas the normal kernel text/data typically starts at vaddr 0xc0008000), causing the output of objcopy (Image) to produce a 3G+ file. This patch makes objcopy strip the .note.gnu.build-id section from the Image file along with all other note sections, which fixes the build.

2007-10-12[ARM] 4599/1: Preserve ATAG list for use with kexec (2.6.23)Mike Westerhof2-1/+58
This patch resolves a kexec boot failure that can occur because no ATAGs are passed in to the kexec'd kernel. Currently the newly-kexec'd kernel may fail if it requires specific ATAGs, or it may fail because the fixed memory location at which it expects to find the ATAGs may contain random data instead of ATAGs. The patch ensures that any ATAGs passed to the current kernel at boot time are copied to a static buffer, and are copied back when kexec copies the new kernel into place. Thus the new kernel sees the same ATAGs from kexec and the boot loader. The boot parameters are copied without regard to type, content, or length -- this patch's scope is limited soley to saving and restoring a fixed-size block of memory containing the kernel's boot parameters. Additional functionality to examine, alter, or replace the ATAGs (using kexec, for example) can be implemented by manipulating the static buffer containing the preserved ATAGs. Note: the size of the buffer (1.5KB) is selected to comfortably hold one of each ATAG type, including a maximum-length command line and the maximum number of ATAG_MEM structures currently supported by the kernel. Should an ATAG list exceed that limit, the list will be silently truncated to that limit (to do other- wise at that point in the boot process would make a simple problem exceedingly complicated). [Note: this is the same patch as 4579, modified to accomodate the ATAG changes introduced in 2.6.23] Signed-off-by: Mike Westerhof <mwester at dls.net> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2007-10-12[ARM] 4539/1: clocksource and clockevents for at91rm9200David Brownell2-65/+132
GENERIC_TIME and GENERIC_CLOCKEVENTS support for the at91rm9200. - Oneshot mode (used for NO_HZ and high res timers) uses the alarm to emulate a real oneshot timer; the trickiest bit is how to avoid some lowlevel races. Thanks to Remy Bohmer for various fixes to this code. - Tighten up periodic mode support using the PIT. - Streamline reads of the 32KHz counter. Thanks to Marc Pignat for some testing results: the CRTR register has *very* odd behavior. The reread appears to work around stranger glitches than just getting an old clock value (which would quickly self-correct). - Remove the rounding-up of tick_usec to 10.009 msec (32KiHz/100), since that no longer acts correct (time increases too fast). Note that the at91sam9 and at91x40 chips need other solutions, since they don't have the same system timer module.
