Use menuconfig instead of flat configs so that you can disable/enable regulator items with one selection. Also, use depends instead of reverse selections to make life easier, too. Signed-off-by:

It seems that some cards are slightly out of spec and occasionally will not be able to complete a write in the alloted 250 ms [1]. Incease the timeout slightly to allow even these cards to function properly. [1] http://lkml.org/lkml/2008/9/23/390Signed-off-by:

Fix the __pfn_to_page(pfn) macro so that it doesn't evaluate its argument twice in the CONFIG_DISCONTIGMEM=y case, because 'pfn' may be a result of a funtion call having side effects. For example, the hibernation code applies pfn_to_page(pfn) to the result of a function returning the pfn corresponding to the next set bit in a bitmap and the current bit position is modified on each call. This leads to "interesting" failures for CONFIG_DISCONTIGMEM=y due to the current behavior of __pfn_to_page(pfn). Signed-off-by:

sched_clock() uses cycles_2_ns() needlessly - which is an irq-disabling variant of __cycles_2_ns(). Most of the time sched_clock() is called with irqs disabled already. The few places that call it with irqs enabled need to be updated. Signed-off-by:

in scheduler-intense workloads native_read_tsc() overhead accounts for 20% of the system overhead: 659567 system_call 41222.9375 686796 schedule 435.7843 718382 __switch_to 665.1685 823875 switch_mm 4526.7857 1883122 native_read_tsc 55385.9412 9761990 total 2.8468 this is large part due to the rdtsc_barrier() that is done before and after reading the TSC. But sched_clock() is not a precise clock in the GTOD sense, using such barriers is completely pointless. So remove the barriers and only use them in vget_cycles(). This improves lat_ctx performance by about 5%. Signed-off-by:

This Kconfig change allows the common 'make allmodconfig' and 'make allyesconfig' build options to skip the staging tree, which is probably what you want to have happen anyway. This makes the linux-next developer's life a lot easier so he doesn't have to worry about changes that break the staging tree, that's for me to worry about... Signed-off-by:

IA64 kdump kernel failed to initialize /proc/vmcore in 2.6.28-rc2. A bug was introduced in this patch commit: d9a9855d always reserve elfcore header memory in crash kernel The problem was that the call to reserve_elfcorehdr() should be placed in CONFIG_CRASH_DUMP rather than in CONFIG_CRASH_KERNEL, which does not exist.

When initializing an uninitialized block group in ext4_new_inode(), its block group checksum must be re-calculated. This fixes a race when several threads try to allocate a new inode in an UNINIT'd group. There is some question whether we need to be initializing the block bitmap in ext4_new_inode() at all, but for now, if we are going to init the block group, let's eliminate the race. Signed-off-by:

Xen requires that all mappings of pagetable pages are read-only, so that they can't be updated illegally. As a result, if a page is being turned into a pagetable page, we need to make sure all its mappings are RO. If the page had been used for ioremap or vmalloc, it may still have left over mappings as a result of not having been lazily unmapped. This change makes sure we explicitly mop them all up before pinning the page. Unlike aliases created by kmap, the there can be vmalloc aliases even for non-high pages, so we must do the flush unconditionally. Signed-off-by:
