git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen * 'stable/bug-fixes-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen: xen: mask_rw_pte: do not apply the early_ioremap checks on x86_32 xen: do not create the extra e820 region at an addr lower than 4G
2011-04-20xen: mask_rw_pte: do not apply the early_ioremap checks on x86_32Stefano Stabellini1-4/+9
The two "is_early_ioremap_ptep" checks in mask_rw_pte are only used on x86_64, in fact early_ioremap is not used at all to setup the initial pagetable on x86_32. Moreover on x86_32 the two checks are wrong because the range pgt_buf_start..pgt_buf_end initially should be mapped RW because the pages in the range are not pagetable pages yet and haven't been cleared yet. Afterwards considering the pgt_buf_start..pgt_buf_end is part of the initial mapping, xen_alloc_pte is capable of turning the ptes RO when they become pagetable pages. Fix the issue and improve the readability of the code providing two different implementation of mask_rw_pte for x86_32 and x86_64.

2011-04-20xen: do not create the extra e820 region at an addr lower than 4GStefano Stabellini1-1/+1
Do not add the extra e820 region at a physical address lower than 4G because it breaks e820_end_of_low_ram_pfn(). It is OK for us to move the xen_extra_mem_start up and down because this is the index of the memory that can be ballooned in/out - it is memory not available to the kernel during bootup.

2011-04-19perf, x86: Fix pre-defined cache-misses event for AMD family 15h cpusAndre Przywara1-1/+1
With AMD cpu family 15h a unit mask was introduced for the Data Cache Miss event (0x041/L1-dcache-load-misses). We need to enable bit 0 (first data cache miss or streaming store to a 64 B cache line) of this mask to proper count data cache misses. Now we set this bit for all families and models. In case a PMU does not implement a unit mask for event 0x041 the bit is ignored.

2011-04-18powerpc/perf_event: Skip updating kernel counters if register value shrinksEric B Munson1-7/+30
Because of speculative event roll back, it is possible for some event coutners to decrease between reads on POWER7. This causes a problem with the way that counters are updated. Delta calues are calculated in a 64 bit value and the top 32 bits are masked. If the register value has decreased, this leaves us with a very large positive value added to the kernel counters. This patch protects against this by skipping the update if the delta would be negative. This can lead to a lack of precision in the coutner values, but from my testing the value is typcially fewer than 10 samples at a time.

2011-04-18powerpc/pseries: Use a kmem cache for DTL buffersNishanth Aravamudan1-2/+10
PAPR specifies that DTL buffers can not cross AMS environments (aka CMO in the PAPR) and can not cross a memory entitlement granule boundary (4k). This is found in section 14.11.3.2 H_REGISTER_VPA of the PAPR. kmalloc does not guarantee an alignment of the allocation, though, beyond 8 bytes (at least in my understanding). Create a special kmem cache for DTL buffers with the alignment requirement. Signed-off-by: Benjamin Herrenschmidt <[email protected]>

Recent commit b987812b3fcaf70fdf0037589e5d2f5f2453e6ce caused a compile failure on UP because a considerably large block of the file was included within CONFIG_SMP, hence making a stub function not exposed on UP builds when it needed to be. Relocate the stub to the #else /* ! CONFIG_SMP */ section and also annotate the relevant else/endif so that nobody else falls into the same trap I did.

Round robin assignment doesn't work because init_numa_sched_groups_power() assumes all logical cpus in the same physical cpu share the same node (then it only accounts for group_first_cpu()), and the simple round robin breaks the above assumption. Thus, this patch implements a reassignment of node-ids if buggy firmware or numa emulation makes wrong cpu node map. Tt enforce all logical cpus in the same physical cpu share the same node.

2011-04-14ARM: S5P: Remove unused s3c_pm_check_resume_pinAbhilash Kesavan1-11/+0
The s3c_pm_check_resume_pin() is not being used and can be safely removed to fix the build warning. Signed-off-by: Abhilash Kesavan <[email protected]> Signed-off-by: Kukjin Kim <[email protected]>
2011-04-13Blackfin: SMP: fix cache flush loopSonic Zhang1-3/+16
The recent commit (10774912647781) wasn't entirely correct. While it fixed some issues, it introduced others. So pull in the fixes from the public cache flush functions, and document why we need to call things directly ourselves.

2011-04-13Blackfin: time-ts: ack gptimer sooner to avoid missing short intsMike Frysinger1-1/+7
If the period of a gptimer is fairly low, we might miss an interrupt by acking it too late (we end up acking the new int as well). Reported-by: Isabelle Leonardi <[email protected]> Signed-off-by: Mike Frysinger <[email protected]>
2011-04-13Blackfin: gptimers: fix thinko when disabling timersMike Frysinger1-1/+1
We only want to clear the run bit for this one timer, not all status bits. So don't read the whole reg and then write all the bits back out. Reported-by: Isabelle Leonardi <[email protected]> Signed-off-by: Mike Frysinger <[email protected]>
2011-04-13Blackfin: SMP: make all barriers handle cache issuesGraf Yang1-18/+18
When suspending/resuming, the common task freezing code will run in parallel and freeze processes on each core. This is because the code uses the non-smp version of memory barriers (as well it should). The Blackfin smp barrier logic at the moment contains the cache sync logic, but the non-smp barriers do not. This is incorrect as Rafel summarized: > ... > The existing memory barriers are SMP barriers too, but they are more > than _just_ SMP barriers. At least that's how it is _supposed_ to be > (eg. rmb() is supposed to be stronger than smp_rmb()). > ... > However, looking at the blackfin's definitions of SMP barriers I see > that it uses extra stuff that should _also_ be used in the definitions > of the mandatory barriers. > ...
