This avoids xtime lag seen with dynticks, because while 'xtime' itself is still not updated often, we keep a 'xtime_cache' variable around that contains the approximate real-time that _is_ updated each time we do a 'update_wall_time()', and is thus never off by more than one tick. IOW, this restores the original semantics for 'xtime' users, as long as you use the proper abstraction functions (ie 'current_kernel_time()' or 'get_seconds()' depending on whether you want a timespec or just the seconds field). [ Updated Patch. As penance for my sins I've also yanked another #ifdef that was added to avoid the xtime lag w/ hrtimers. ] Signed-off-by: NJohn Stultz <johnstul@us.ibm.com> Cc: Ingo Molnar <mingo@elte.hu> Cc: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

This avoids use of the kernel-internal "xtime" variable directly outside of the actual time-related functions. Instead, use the helper functions that we already have available to us. This doesn't actually change any behaviour, but this will allow us to fix the fact that "xtime" isn't updated very often with CONFIG_NO_HZ (because much of the realtime information is maintained as separate offsets to 'xtime'), which has caused interfaces that use xtime directly to get a time that is out of sync with the real-time clock by up to a third of a second or so.

Testing the wrong bit caused kvm not to disable nx on the guest when it is disabled on the host (an mmu optimization relies on the nx bits being the same in the guest and host). This allows Windows to boot when nx is disabled on te host (e.g. when host pae is disabled). Signed-off-by: NAvi Kivity <avi@qumranet.com>

We can't mark the whole thing init because there are dependencies in bootloaders that assume that _start, or whatever the image entry value, is 2 instructions before the "HdrS" signature. In fact, TILO assumes this entry is always at 0x4000, yikes! Also, right after the bootloader info area there are OBP strings and values that get used later in the boot process, and those are not all provably .init yet. Signed-off-by: NDavid S.

ACPI implementations in several TOSHIBA laptops are weird and burn cpu cycles for tens of seconds while trying to suspend if the PCI device for the ATA controller is disabled when the ACPI suspend is called. This patch uses DMI to match those machines and bypass device disable on those machines during suspend. As the device needs to be put into enabled state on resume without affecting PCI enable count, matching resume callback uses __pci_reenable_device().
