These symbols are only referenced in this source file so can be made static, and the efficiency table is constant data so can be declared as such. This avoids polluting the global namespace and fixes warnings from sparse. The function arch_scale_freq_power() is still not prototyped or static, this is a separate issue as this is overriding a weak symbol from the scheduler which neglects to provide a prototype.

There is a miscompilation of csum_tcpudp_magic() due to the way we pass the asm() operands in. Fortunately, this doesn't affect the IP code, but can affect anyone who passes ntohs(udp->len) as the length argument, or protocols with more than 8 bits. The problem stems from passing 16-bit operands into an asm() - GCC makes no guarantees about what may be in the high 16-bits of such a register passed into assembly which is in the "HI" machine mode. Address this by changing the way we handle the 16-bit arguments - since accumulating the protocol and length can never overflow, we can delegate this to the compiler to perform, and then accumulate it into the checksum inside the asm(), taking account of the endian-ness via an appropriate 32-bit rotation. While we are here, also realise that there's a chance to optimise this a little: several callers from IP code pass a constant zero as the initial sum. This is wasteful - if we detect this condition, we can optimise away one instruction. Tested-by: NMaxime Bizon <mbizon@freebox.fr> Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

Set-associative caches on all v7 implementations map the index bits to physical addresses LSBs and tag bits to MSBs. As the last level of cache on current and upcoming ARM systems grows in size, this means that under normal DRAM controller configurations, the current v7 cache flush routine using set/way operations triggers a DRAM memory controller precharge/activate for every cache line writeback since the cache routine cleans lines by first fixing the index and then looping through ways (index bits are mapped to lower physical addresses on all v7 cache implementations; this means that, with last level cache sizes in the order of MBytes, lines belonging to the same set but different ways map to different DRAM pages). Given the random content of cache tags, swapping the order between indexes and ways loops do not prevent DRAM pages precharge and activate cycles but at least, on average, improves the chances that either multiple lines hit the same page or multiple lines belong to different DRAM banks, improving throughput significantly. This patch swaps the inner loops in the v7 cache flushing routine to carry out the clean operations first on all sets belonging to a given way (looping through sets) and then decrementing the way. Benchmarks showed that by swapping the ordering in which sets and ways are decremented in the v7 cache flushing routine, that uses set/way operations, time required to flush caches is reduced significantly, owing to improved writebacks throughput to the DRAM controller. Benchmarks results vary and depend heavily on the last level of cache tag RAM content when cache is cleaned and invalidated, ranging from 2x throughput when all tag RAM entries contain dirty lines mapping to sequential pages of RAM to 1x (ie no improvement) when all tag RAM accesses trigger a DRAM precharge/activate cycle, as the current code implies on most DRAM controller configurations.

Since commit 36bc08cc ("fs/aio: Add support to aio ring pages migration") the aio ring setup code has used a special per-ring backing inode for the page allocations, rather than just using random anonymous pages. However, rather than remembering the pages as it allocated them, it would allocate the pages, insert them into the file mapping (dirty, so that they couldn't be free'd), and then forget about them. And then to look them up again, it would mmap the mapping, and then use "get_user_pages()" to get back an array of the pages we just created. Now, not only is that incredibly inefficient, it also leaked all the pages if the mmap failed (which could happen due to excessive number of mappings, for example). So clean it all up, making it much more straightforward. Also remove some left-overs of the previous (broken) mm_populate() usage that was removed in commit d6c355c7 ("aio: fix race in ring buffer page lookup introduced by page migration support") but left the pointless and now misleading MAP_POPULATE flag around.

The arbitrary restriction on page counts offered by the core migrate_page_move_mapping() code results in rather suspicious looking fiddling with page reference counts in the aio_migratepage() operation. To fix this, make migrate_page_move_mapping() take an extra_count parameter that allows aio to tell the code about its own reference count on the page being migrated. While cleaning up aio_migratepage(), make it validate that the old page being passed in is actually what aio_migratepage() expects to prevent misbehaviour in the case of races.

Commit 1bf49dd4 ("./Makefile: export initial ramdisk compression config option") started setting the INITRD_COMPRESS environment variable depending on which decompression models the kernel had available. That is completely broken. For example, we by default have CONFIG_RD_LZ4 enabled, and are able to decompress such an initrd, but the user tools to *create* such an initrd may not be availble. So trying to tell dracut to generate an lz4-compressed image just because we can decode such an image is completely inappropriate.

Commit 81c0a2bb ("mm: page_alloc: fair zone allocator policy") meant to bring aging fairness among zones in system, but it was overzealous and badly regressed basic workloads on NUMA systems. Due to the way kswapd and page allocator interacts, we still want to make sure that all zones in any given node are used equally for all allocations to maximize memory utilization and prevent thrashing on the highest zone in the node. While the same principle applies to NUMA nodes - memory utilization is obviously improved by spreading allocations throughout all nodes - remote references can be costly and so many workloads prefer locality over memory utilization. The original change assumed that zone_reclaim_mode would be a good enough predictor for that, but it turned out to be as indicative as a coin flip. Revert the NUMA aspect of the fairness until we can find a proper way to make it configurable and agree on a sane default.

Sasha Levin found a NULL pointer dereference that is due to a missing page table lock, which in turn is due to the pmd entry in question being a transparent huge-table entry. The code - introduced in commit 1998cc04 ("mm: make madvise(MADV_WILLNEED) support swap file prefetch") - correctly checks for this situation using pmd_none_or_trans_huge_or_clear_bad(), but it turns out that that function doesn't work correctly. pmd_none_or_trans_huge_or_clear_bad() expected that pmd_bad() would trigger if the transparent hugepage bit was set, but it doesn't do that if pmd_numa() is also set. Note that the NUMA bit only gets set on real NUMA machines, so people trying to reproduce this on most normal development systems would never actually trigger this. Fix it by removing the very subtle (and subtly incorrect) expectation, and instead just checking pmd_trans_huge() explicitly.

Pull Xen bugfixes from Konrad Rzeszutek Wilk: - Fix balloon driver for auto-translate guests (PVHVM, ARM) to not use scratch pages. - Fix block API header for ARM32 and ARM64 to have proper layout - On ARM when mapping guests, stick on PTE_SPECIAL - When using SWIOTLB under ARM, don't call swiotlb functions twice - When unmapping guests memory and if we fail, don't return pages which failed to be unmapped. - Grant driver was using the wrong address on ARM. * tag 'stable/for-linus-3.13-rc4-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip: xen/balloon: Seperate the auto-translate logic properly (v2) xen/block: Correctly define structures in public headers on ARM32 and ARM64 arm: xen: foreign mapping PTEs are special. xen/arm64: do not call the swiotlb functions twice xen: privcmd: do not return pages which we have failed to unmap XEN: Grant table address, xen_hvm_resume_frames, is a phys_addr not a pfn

Merge tag 'trace-fixes-v3.13-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull ftrace fix from Steven Rostedt: "This fixes a long standing bug in the ftrace profiler. The problem is that the profiler only initializes the online CPUs, and not possible CPUs. This causes issues if the user takes CPUs online or offline while the profiler is running. If we online a CPU after starting the profiler, we lose all the trace information on the CPU going online. If we offline a CPU after running a test and start a new test, it will not clear the old data from that CPU. This bug causes incorrect data to be reported to the user if they online or offline CPUs during the profiling" * tag 'trace-fixes-v3.13-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: ftrace: Initialize the ftrace profiler for each possible cpu
