Introduce support for registering an IPI IRQ domain suitable for use by systems using the MIPS MT (multithreading) ASE within a single core. This will allow for such systems to be supported generically, without the current kludge of IPI code split between the MIPS arch & the malta board support code.

The various struct irq_chip callbacks in the MIPS CPU interrupt controller driver have been calculating the hardware interrupt number by subtracting MIPS_CPU_IRQ_BASE from the virq number. This presumes a linear mapping beginning from MIPS_CPU_IRQ_BASE, and this will not hold once an IPI IRQ domain is introduced. Switch to using the hwirq field of struct irq_data which already contains the hardware interrupt number instead of attempting to calculate it. Similarly, plat_irq_dispatch calculated the virq number by adding MIPS_CPU_IRQ_BASE to the hardware interrupt number. Ready this for the introduction of an IPI IRQ domain by instead using irq_linear_revmap.

Replace use of the magic number 0x100 (ie. bit 8) with the more explanatory IE_SW0 (ie. interrupt enable for software interrupt 0) or C_SW0 (ie. cause bit for software interrupt 0) as appropriate.

We declare CONFIG_ARCH_HAS_ILOG2_U32 & CONFIG_ARCH_HAS_ILOG2_U64 in Kconfig, but they are always false since nothing ever selects them.

The generic_defconfig is used for platforms like SEAD3 which do not usually have fixed storage available, therefore NFS is the preferred location of the RFS. When the upstream kernel defconfig is built & tested on platforms such as SEAD3 this leads to essentially false failures when the RFS fails to mount. There is little harm in having this feature enabled by default, so enable it in the defconfig. Kernel autoconfiguration & DHCP must also be selected to allow RFS on NFS.

It is pure mystery to me why we need to be on a specific CPU while looking up a value in an array. My best shot at this is that before commit d4019f0a ("cpufreq: move freq change notifications to cpufreq core") it was required to invoke cpufreq_notify_transition() on a special CPU.

We always either target MIPS32/MIPS64 or microMIPS, and always include one & only one of uasm-mips.c or uasm-micromips.c. Therefore the abstraction of the ISA in asm/uasm.h declaring functions for either ISA is redundant & needless. Remove it to simplify the code.

Douglas Leung authored
Correct the treatment of branching conditions for BC1EQZ and BC1NEZ instructions in function isBranchInstr(). Previously, corresponding conditions were swapped, which in turn meant that, for these two instructions, function isBranchInstr() returned wrong value in its output parameter contpc. This change is actually an extension of the fix done by the commit 93583e17 ("MIPS: math-emu: Fix BC1{EQ,NE}Z emulation"). That commit dealt with a similar problem in function cop1Emulate(), while this commit deals with condition handling in function isBranchInstr(). The code styles of changes in these two commits are kept as consistent as possible.

Add missing clearing of BLTZALL and BGEZALL emulation counters in function mipsr2_stats_clear_show(). Previously, it was not possible to reset BLTZALL and BGEZALL emulation counters - their value remained the same even after explicit request via debugfs. As far as other related counters are concerned, they all seem to be properly cleared. This change affects debugfs operation only, core R2 emulation functionality is not affected.

Leonid Yegoshin authored
Fix the problem of inaccurate identification of instructions BLEZL and BGTZL in R2 emulation code by making sure all necessary encoding specifications are met. Previously, certain R6 instructions could be identified as BLEZL or BGTZL. R2 emulation routine didn't take into account that both BLEZL and BGTZL instructions require their rt field (bits 20 to 16 of instruction encoding) to be 0, and that, at same time, if the value in that field is not 0, the encoding may represent a legitimate MIPS R6 instruction. This means that a problem could occur after emulation optimization, when emulation routine tried to pipeline emulation, picked up a next candidate, and subsequently misrecognized an R6 instruction as BLEZL or BGTZL. It should be said that for single pass strategy, the problem does not happen because CPU doesn't trap on branch-compacts which share opcode space with BLEZL/BGTZL (but have rt field != 0, of course).

Some users must have 4K pages while needing a 48-bit VA space size. The cleanest way do do this is to go to a 4-level page table for this case. Each page table level using order-0 pages adds 9 bits to the VA size (at 4K pages, so for four levels we get 9 * 4 + 12 == 48-bits. For the 4K page size case only we add support functions for the PUD level of the page table tree, also the TLB exception handlers get an extra level of tree walk.

Pull block fixes from Jens Axboe: "Here's a pull request for 4.11-rc, fixing a set of issues mostly centered around the new scheduling framework. These have been brewing for a while, but split up into what we absolutely need in 4.11, and what we can defer until 4.12. These are well tested, on both single queue and multiqueue setups, and with and without shared tags. They fix several hangs that have happened in testing. This is obviously larger than I would have preferred at this point in time, but I don't think we can shave much off this and still get the desired results. In detail, this pull request contains: - a set of five fixes for NVMe, mostly from Christoph and one from Roland. - a series from Bart, fixing issues with dm-mq and SCSI shared tags and scheduling. Note that one of those patches commit messages may read like an optimization, but it is in fact an important fix for queue restarts in particular. - a series from Omar, most importantly fixing a hang with multiple hardware queues when we fail to get a driver tag. Another important fix in there is for resizing hardware queues, which nbd does when handling multiple sockets for one connection. - fixing an imbalance in putting the ctx for hctx request allocations from Minchan" * 'for-linus' of git://git.kernel.dk/linux-block: blk-mq: Restart a single queue if tag sets are shared dm rq: Avoid that request processing stalls sporadically scsi: Avoid that SCSI queues get stuck blk-mq: Introduce blk_mq_delay_run_hw_queue() blk-mq: remap queues when adding/removing hardware queues blk-mq-sched: fix crash in switch error path blk-mq-sched: set up scheduler tags when bringing up new queues blk-mq-sched: refactor scheduler initialization blk-mq: use the right hctx when getting a driver tag fails nvmet: fix byte swap in nvmet_parse_io_cmd nvmet: fix byte swap in nvmet_execute_write_zeroes nvmet: add missing byte swap in nvmet_get_smart_log nvme: add missing byte swap in nvme_setup_discard nvme: Correct NVMF enum values to match NVMe-oF rev 1.0 block: do not put mq context in blk_mq_alloc_request_hctx
