[PATCH 00 of 11] mmu notifier #v16
Hello, this is the last update of the mmu notifier patch. Jack asked a __mmu_notifier_register to call under mmap_sem in write mode.

[PATCH] apm: make apm=power-off configurable like apm=realmode-power-off
On some systems (with broken BIOSes?) apm=power-off should be appended as kernel parameter. apm=realmode-power-off is configurable during compile-time. apm=power-off should be configurable likewise. On non-SMP systems apm=power-off is the default. For kernels with SMP support it is not. Signed-off-by: Niels d... 7 May 2008 10:58
