This fixes a problems with the set up of Linux memory: - When reserving memory at boot time, the code previously reserved the bottom page of memory, and then from one page up to the end of the bootmap. This had the desired effect, but was strictly speaking wrong, as the one page was actually whatever CONFIG_ZERO_PAGE_OFFSET had been set to.

This fixes a problem in the code which copies the vmalloc portion of the kernel's page table into the current user space page table. The addition of the four level page table code breaks on folded page tables, because the pud level is always present (although folded). This updates the code to use the same style of updates for the pud as is used for the pgd level. Signed-off-by: NStuart Menefy <stuart.menefy@st.com> Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

Exception stacks are allocated each time a CPU is set online. But the allocated space is never freed. Thus with one CPU hotplug offline/online cycle there is a memory leak of 24K (6 pages) for a CPU. Fix is to allocate exception stacks only once -- when the CPU is set online for the first time.

Krzysztof Helt found MTRR is not detected on k6-2 root cause: we moved mtrr_bp_init() early for mtrr trimming, and in early_detect we only read the CPU capability from cpuid, so some cpu doesn't have that bit in cpuid. So we need to add early_init_xxxx to preset those bit before mtrr_bp_init for those earlier cpus. this patch is for v2.6.27 Reported-by: NKrzysztof Helt <krzysztof.h1@wp.pl> Signed-off-by: NYinghai Lu <yhlu.kernel@gmail.com> Signed-off-by: NIngo Molnar <mingo@elte.hu>

The current check for monotonicity is way too weak: Andreas Mohr reports ( http://lkml.org/lkml/2008/8/10/77 ) that on one of his test systems the current check only triggers in 50% of all cases, leading to catastrophic timer behaviour. To fix this issue, expand the check for monotonicity by doing ten consecutive tests instead of one.

On all hardware (some Intel ICH4, PIIX4 and PIIX4E chipsets) affected by a hardware errata there's about a 4.2% chance that initialization of the ACPI PMTMR fails. On those chipsets, we need to read out the timer value at least three times to get a correct result, for every once in a while (i.e. within a 3 ns window every 69.8 ns) the read returns a bogus result. During normal operation we work around this issue, but during initialization reading a bogus value may lead to -EINVAL even though the hardware is usable. Thanks to Andreas Mohr for spotting this issue.

We have a bug in the calculation of the next jiffie to trigger the RTC synchronisation. The aim here is to run sync_cmos_clock() as close as possible to the middle of a second. Which means we want this function to be called less than or equal to half a jiffie away from when now.tv_nsec equals 5e8 (500000000). If this is not the case for a given call to the function, for this purpose instead of updating the RTC we calculate the offset in nanoseconds to the next point in time where now.tv_nsec will be equal 5e8. The calculated offset is then converted to jiffies as these are the unit used by the timer. Hovewer timespec_to_jiffies() used here uses a ceil()-type rounding mode, where the resulting value is rounded up. As a result the range of now.tv_nsec when the timer will trigger is from 5e8 to 5e8 + TICK_NSEC rather than the desired 5e8 - TICK_NSEC / 2 to 5e8 + TICK_NSEC / 2. As a result if for example sync_cmos_clock() happens to be called at the time when now.tv_nsec is between 5e8 + TICK_NSEC / 2 and 5e8 to 5e8 + TICK_NSEC, it will simply be rescheduled HZ jiffies later, falling in the same range of now.tv_nsec again. Similarly for cases offsetted by an integer multiple of TICK_NSEC. This change addresses the problem by subtracting TICK_NSEC / 2 from the nanosecond offset to the next point in time where now.tv_nsec will be equal 5e8, effectively shifting the following rounding in timespec_to_jiffies() so that it produces a rounded-to-nearest result.
