Current memfree FW has a bug which in some cases, assumes that ICM pages passed to it are cleared. This patch uses __GFP_ZERO to allocate all ICM pages passed to the FW.

2008-06-20[watchdog] hpwdt: fix use of inline assemblyLinus Torvalds
The inline assembly in drivers/watchdog/hpwdt.c was incredibly broken, and included all the function prologue and epilogue stuff, even though it was itself then inside a C function where the compiler would add its own prologue and epilogue on top of it all. This then just _happened_ to work if you had exactly the right compiler version and exactly the right compiler flags, so that gcc just happened to not create any prologue at all (the gcc-generated epilogue wouldn't matter, since it would never be reached). But the more proper way to fix it is to simply not do this. Move the inline asm to the top level, with no surrounding function at all (the better alternative would be to remove the prologue and make it actually use proper description of the arguments to the inline asm, but that's a bigger change than the one I'm willing to make right now).

2008-06-20x86: fix NULL pointer deref in __switch_toSuresh Siddha
I am able to reproduce the oops reported by Simon in __switch_to() with lguest. My debug showed that there is at least one lguest specific issue (which should be present in 2.6.25 and before aswell) and it got exposed with a kernel oops with the recent fpu dynamic allocation patches. In addition to the previous possible scenario (with fpu_counter), in the presence of lguest, it is possible that the cpu's TS bit it still set and the lguest launcher task's thread_info has TS_USEDFPU still set. This is because of the way the lguest launcher handling the guest's TS bit. (look at lguest_set_ts() in lguest_arch_run_guest()). This can result in a DNA fault while doing unlazy_fpu() in __switch_to(). This will end up causing a DNA fault in the context of new process thats getting context switched in (as opossed to handling DNA fault in the context of lguest launcher/helper process). This is wrong in both pre and post 2.6.25 kernels. In the recent 2.6.26-rc series, this is showing up as NULL pointer dereferences or sleeping function called from atomic context(__switch_to()), as we free and dynamically allocate the FPU context for the newly created threads. Older kernels might show some FPU corruption for processes running inside of lguest. With the appended patch, my test system is running for more than 50 mins now. So atleast some of your oops (hopefully all!) should get fixed. Please give it a try. I will spend more time with this fix tomorrow.
