The entire bpf_jit_asm.S is written in noreorder mode because "we know better" according to a comment. This also prevented the assembler from throwing in the required NOPs for MIPS I processors which have no load-use interlock, thus the load's consumer might end up using the old value of the register from prior to the load. Fixed by putting the assembler in reorder mode for just the affected load instructions. This is not enough for gas to actually try to be clever by looking at the next instruction and inserting a nop only when needed but as the comment said "we know better", so getting gas to unconditionally emit a NOP is just right in this case and prevents adding further ifdefery.

The CONFIG_MIPS_MT symbol can be selected by CONFIG_MIPS_VPE_LOADER in addition to CONFIG_MIPS_MT_SMP. We only want MT code in the CPS SMP boot vector if we're using MT for SMP.

The MT-specific code in mips_cps_boot_vpes can safely be omitted from kernels which don't support MT, with the default VPE==0 case being used as it would be after the has_mt (Config3.MT) check failed at runtime. Discarding the code entirely will save us a few bytes & allow cleaner handling of MT ASE instructions by later patches.

The has_mt macro ended with a branch, leaving its callers with a delay slot that would be executed if Config3.MT is not set. However it would not be executed if Config3 (or earlier Config registers) don't exist which makes it somewhat inconsistent at best. Fill the delay slot in the macro & fix the mips_cps_boot_vpes caller appropriately.

If there is a DMA zone (usually 24bit = 16MB I believe), but no DMA32 zone, as is the case for some 32-bit kernels, then massage_gfp_flags() will cause DMA memory allocated for devices with a 32..63-bit coherent_dma_mask to fall back to using __GFP_DMA, even though there may only be 32-bits of physical address available anyway. Correct that case to compare against a mask the size of phys_addr_t instead of always using a 64-bit mask.

MAARs should be initialised on each CPU (or rather, core) in the system in order to achieve consistent behaviour & performance. Previously they have only been initialised on the boot CPU which leads to performance problems if tasks are later scheduled on a secondary CPU, particularly if those tasks make use of unaligned vector accesses where some CPUs don't handle any cases in hardware for non-speculative memory regions. Fix this by recording the MAAR configuration from the boot CPU and applying it to secondary CPUs as part of their bringup.

gic_handle_shared_int reads the GIC interrupt pending & mask registers directly into a bitmap, which is defined as an array of unsigned longs. The GIC pending registers may be 32 bits wide if the CM is older than CM3, regardless of the bit width of the CPU, but for MIPS64 kernels the unsigned longs in the bitmap will be 64 bits wide. In this case we need to perform 2 x 32 bit reads per 64 bit unsigned long in order to avoid missing interrupts.

R6 removed the Config4.MMUExtDef field, with the low 16 bits only allowed to contain FTLB fields, and commit e87569cd ("MIPS: cpu-probe: Fix VTLB/FTLB configuration for R6") updated the probing of this field to assume an FTLB is always present for R6. However the FTLB may still be absent. The presence of those fields is actually specified by the MMU type in the Config.MT field, so use that (the new cpu_has_ftlb) to determine whether the FTLB is actually present.

Pull block updates from Jens Axboe: "This is a bit bigger than it should be, but I could (did) not want to send it off last week due to both wanting extra testing, and expecting a fix for the bounce regression as well. In any case, this contains: - Fix for the blk-merge.c compilation warning on gcc 5.x from me. - A set of back/front SG gap merge fixes, from me and from Sagi. This ensures that we honor SG gapping for integrity payloads as well. - Two small fixes for null_blk from Matias, fixing a leak and a capacity propagation issue. - A blkcg fix from Tejun, fixing a NULL dereference. - A fast clone optimization from Ming, fixing a performance regression since the arbitrarily sized bio's were introduced. - Also from Ming, a regression fix for bouncing IOs" * 'for-linus' of git://git.kernel.dk/linux-block: block: fix bounce_end_io block: blk-merge: fast-clone bio when splitting rw bios block: blkg_destroy_all() should clear q->root_blkg and ->root_rl.blkg block: Copy a user iovec if it includes gaps block: Refuse adding appending a gapped integrity page to a bio block: Refuse request/bio merges with gaps in the integrity payload block: Check for gaps on front and back merges null_blk: fix wrong capacity when bs is not 512 bytes null_blk: fix memory leak on cleanup block: fix bogus compiler warnings in blk-merge.c

Commit 505a666e ("writeback: plug writeback in wb_writeback() and writeback_inodes_wb()") has us holding a plug during writeback_sb_inodes, which increases the merge rate when relatively contiguous small files are written by the filesystem. It helps both on flash and spindles. For an fs_mark workload creating 4K files in parallel across 8 drives, this commit improves performance ~9% more by unplugging before calling cond_resched(). cond_resched() doesn't trigger an implicit unplug, so explicitly getting the IO down to the device before scheduling reduces latencies for anyone waiting on clean pages. It also cuts down on how often we use kblockd to unplug, which means less work bouncing from one workqueue to another. Many more details about how we got here: https://lkml.org/lkml/2015/9/11/570Signed-off-by: NChris Mason <clm@fb.com> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

The various definitions of __pfn_to_phys() have been consolidated to use a generic macro in include/asm-generic/memory_model.h. This hit mainline in the form of 012dcef3 "mm: move __phys_to_pfn and __pfn_to_phys to asm/generic/memory_model.h". When the generic macro was implemented the type cast to phys_addr_t was dropped which caused boot regressions on ARM platforms with more than 4GB of memory and LPAE enabled. It was suggested to use PFN_PHYS() defined in include/linux/pfn.h as provides the correct logic and avoids further duplication.

Some of the device files are required to be user accessible for PSM while most should remain accessible only by root. Add a parameter to hfi1_cdev_init which controls if the user should have access to this device which places it in a different class with the appropriate devnode callback. In addition set the devnode call back for the existing class to be a bit more explicit for those permissions. Finally remove the unnecessary null check before class_destroy Tested-by: NDonald Dutile <ddutile@redhat.com> Signed-off-by: Haralanov, Mitko (mitko.haralanov@intel.com) Signed-off-by: NIra Weiny <ira.weiny@intel.com> Signed-off-by: NDoug Ledford <dledford@redhat.com>

I added spaces around operators so it matches kernel style because normally "-1ULL" is a number and " - 1" is a subtract operation. Also removed some superflous "ULL" types so "1ULL" becomes "1".
