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.

git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-2.6 * 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-2.6: (867 commits) [SKY2]: status polling loop (post merge) [NET]: Fix NAPI completion handling in some drivers.

(The latter files seem to be explicitly _designed_ to get conflicts when different subsystems work with them - that have an absolutely horrid lack of subsystem separation!)

2007-10-12[MIPS] Don't abort the build process if '-msym32' isn't supportedFranck Bui-Huu1-1/+3
-msym32 and previously the strategy to tell the compiler to generate 64-bit code but the assembler to put it into 32-bit ELF was initially a hack to get around the lack of proper 64-bit binutils support and later turned into a neat optimization with significant code size savings. But it's really just an optimization so there is nothing wrong with just dropping the option (and whatever else goes along with it, I forgot all the nasty details) on the floor if due to a vintage compiler it can't be suported.

2007-10-12[MIPS] Dyntick support for SMTC:Ralf Baechle4-49/+134
The kernel currently only supports broadcasting of the timer interrupt from a single timer, not multicasting into two multicast groups of processors.

2007-10-12[MIPS] Switch from to_tm to rtc_time_to_tmRalf Baechle6-56/+14
This replaces the MIPS-specific to_tm function with the generic rtc_time_to_tm function. The big difference between the two functions is that rtc_time_to_tm uses epoch 70 while to_tm uses 1970, so the result of rtc_time_to_tm needs to be fixed up. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
