2011-04-28mm: check if PTE is already allocated during page faultMel Gorman1-1/+1
With transparent hugepage support, handle_mm_fault() has to be careful that a normal PMD has been established before handling a PTE fault. To achieve this, it used __pte_alloc() directly instead of pte_alloc_map as pte_alloc_map is unsafe to run against a huge PMD. pte_offset_map() is called once it is known the PMD is safe. pte_alloc_map() is smart enough to check if a PTE is already present before calling __pte_alloc but this check was lost. As a consequence, PTEs may be allocated unnecessarily and the page table lock taken. Thi useless PTE does get cleaned up but it's a performance hit which is visible in page_test from aim9. This patch simply re-adds the check normally done by pte_alloc_map to check if the PTE needs to be allocated before taking the page table lock. The effect is noticable in page_test from aim9.

2011-04-28memcg: update documentation to describe usage_in_bytesDaisuke Nishimura1-2/+13
Since 569b846d ("memcg: coalesce uncharge during unmap/truncate"), we do batched (delayed) uncharge at truncation/unmap. And since cdec2e42(memcg: coalesce charging via percpu storage), we have percpu cache for res_counter. These changes improved performance of memory cgroup very much, but made res_counter->usage usually have a bigger value than the actual value of memory usage. So, *.usage_in_bytes, which show res_counter->usage, are not desirable for precise values of memory(and swap) usage anymore. Instead of removing these files completely(because we cannot know res_counter->usage without them), this patch updates the meaning of those files.

2011-04-28mm: thp: fix /dev/zero MAP_PRIVATE and vm_flags cleanupsAndrea Arcangeli3-21/+27
The huge_memory.c THP page fault was allowed to run if vm_ops was null (which would succeed for /dev/zero MAP_PRIVATE, as the f_op->mmap wouldn't setup a special vma->vm_ops and it would fallback to regular anonymous memory) but other THP logics weren't fully activated for vmas with vm_file not NULL (/dev/zero has a not NULL vma->vm_file). So this removes the vm_file checks so that /dev/zero also can safely use THP (the other albeit safer approach to fix this bug would have been to prevent the THP initial page fault to run if vm_file was set). After removing the vm_file checks, this also makes huge_memory.c stricter in khugepaged for the DEBUG_VM=y case. It doesn't replace the vm_file check with a is_pfn_mapping check (but it keeps checking for VM_PFNMAP under VM_BUG_ON) because for a is_cow_mapping() mapping VM_PFNMAP should only be allowed to exist before the first page fault, and in turn when vma->anon_vma is null (so preventing khugepaged registration). So I tend to think the previous comment saying if vm_file was set, VM_PFNMAP might have been set and we could still be registered in khugepaged (despite anon_vma was not NULL to be registered in khugepaged) was too paranoid. The is_linear_pfn_mapping check is also I think superfluous (as described by comment) but under DEBUG_VM it is safe to stay.

2011-04-28vfs: avoid large kmalloc()s for the fdtableAndrew Morton1-7/+11
Azurit reports large increases in system time after 2.6.36 when running Apache. It was bisected down to a892e2d7dcdfa6c76e6 ("vfs: use kmalloc() to allocate fdmem if possible"). That patch caused the vfs to use kmalloc() for very large allocations and this is causing excessive work (and presumably excessive reclaim) within the page allocator. Fix it by falling back to vmalloc() earlier - when the allocation attempt would have been considered "costly" by reclaim.

2011-04-28x86: devicetree: Configure IOAPIC pin only onceSebastian Andrzej Siewior3-7/+7
We use io_apic_setup_irq_pin() in order to configure pin's interrupt number polarity and type. This is done on every irq_create_of_mapping() which happens for instance during pci enable calls. Level typed interrupts are masked by default, edge are unmasked. On the first ->xlate() call the level interrupt is configured and masked. The driver calls request_irq() and the line is unmasked. Lets assume the interrupt line is shared with another device and we call pci_enable_device() for this device. The ->xlate() configures the pin again and it is masked. request_irq() does not unmask the line because it _is_ already unmasked according to its internal state. So the interrupt will never be unmasked again. This patch is based on an earlier work by Torben Hohn and solves the problem by configuring the pin only once. Since all devices must agree on the same type and polarity there is no point in configuring the pin more than once.

2011-04-27NFSv4: Ensure we request the ordinary fileid when doing readdirplusTrond Myklebust2-17/+16
When readdir() returns a directory entry for the root of a mounted filesystem, Linux follows the old convention of returning the inode number of the covered directory (despite newer versions of POSIX declaring that this is a bug). To ensure this continues to work, the NFSv4 readdir implementation requests the 'mounted-on-fileid' from the server. However, readdirplus also needs to instantiate an inode for this entry, and for that, we also need to request the real fileid as per this patch.

2011-04-27m68k/mm: Set all online nodes in N_NORMAL_MEMORYMichael Schmitz1-0/+2
For m68k, N_NORMAL_MEMORY represents all nodes that have present memory since it does not support HIGHMEM. This patch sets the bit at the time node_present_pages has been set by free_area_init_node. At the time the node is brought online, the node state would have to be done unconditionally since information about present memory has not yet been recorded. If N_NORMAL_MEMORY is not accurate, slub may encounter errors since it uses this nodemask to setup per-cache kmem_cache_node data structures. This pach is an alternative to the one proposed by David Rientjes <rientjes@google.com> attempting to set node state immediately when bringing the node online.

2011-04-26init/Kconfig: fix EXPERT menu listRandy Dunlap1-8/+8
The EXPERT menu list was recently broken by the insertion of a kconfig symbol (EMBEDDED) at the beginning of the EXPERT list of kconfig items. Broken by: commit 6a108a14fa356ef607be308b68337939e56ea94e Author: David Rientjes <rientjes@google.com> Date: Thu Jan 20 14:44:16 2011 -0800 kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT Restore the EXPERT menu list -- don't inject a symbol (EMBEDDED) that does not depend on EXPERT into the list.

2011-04-26amd64_edac: Erratum #637 workaroundBorislav Petkov2-2/+51
F15h CPUs may report a non-DRAM address when reporting an error address belonging to a CC6 state save area. Add a workaround to detect this condition and compute the actual DRAM address of the error as documented in the Revision Guide for AMD Family 15h Models 00h-0Fh Processors.

2011-04-26amd64_edac: Factor in CC6 save areaBorislav Petkov2-1/+29
F15h and later use a portion of DRAM as a CC6 storage area. BIOS programs D18F1x[17C:140,7C:40] DRAM Base/Limit accordingly by subtracting the storage area from the DRAM limit setting. However, in order for edac to consider that part of DRAM too, we need to include it into the per-node range. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2011-04-26amd64_edac: Remove node interleave warningBorislav Petkov1-5/+1
This warning was wrongfully added for a normal condition - intlvsel actually selects the destination node when node interleaving is enabled and it is not a mismatch. For a detailed example, see section 2.8.10.2 "Node Interleaving" in F10h BKDG. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
