2016-02-12mtd: atmel_nand: Support variable RB_EDGE interruptsRomain Izard
The NFC controller used to accelerate the NAND transfers on SAMA5 chips can use either RB_EDGE0 or RB_EDGE3 as its ready/busy interrupt bit. Use the controller's compatible string to select the correct bit.

2016-01-24vmstat: Remove BUG_ON from vmstat_updateChristoph Lameter
If we detect that there is nothing to do just set the flag and do not check if it was already set before. Races really do not matter. If the flag is set by any code then the shepherd will start dealing with the situation and reenable the vmstat workers when necessary again. Since commit 0eb77e988032 ("vmstat: make vmstat_updater deferrable again and shut down on idle") quiet_vmstat might update cpu_stat_off and mark a particular cpu to be handled by vmstat_shepherd. This might trigger a VM_BUG_ON in vmstat_update because the work item might have been sleeping during the idle period and see the cpu_stat_off updated after the wake up. The VM_BUG_ON is therefore misleading and no more appropriate. Moreover it doesn't really suite any protection from real bugs because vmstat_shepherd will simply reschedule the vmstat_work anytime it sees a particular cpu set or vmstat_update would do the same from the worker context directly. Even when the two would race the result wouldn't be incorrect as the counters update is fully idempotent.

2016-01-24MIPS: KVM: Use cacheops.h definitionsJames Hogan
Drop the custom cache operation code definitions used by KVM for emulating guest CACHE instructions, and switch to use the existing definitions in <asm/cacheops.h>.

2016-01-24MIPS: Break down cacheops.h definitionsJames Hogan
Most of the cache op codes defined in cacheops.h are split into a 2-bit cache identifier, and a 3-bit cache op code which does largely the same thing semantically regardless of the cache identifier. To allow the use of these definitions by KVM for decoding cache ops, break the definitions down into parts where it makes sense to do so, and add masks for the Cache and Op field within the cache op.

2016-01-24MIPS: Use EXCCODE_ constants with set_except_vector()James Hogan
The first argument to set_except_vector is the ExcCode, which we now have definitions for. Lets make use of them.

2016-01-24MIPS: Update trap codesJames Hogan
Add a few missing trap codes. [ralf@linux-mips.org: Drop removal of exception codes. I don't care what the incomplete architecture spec says; it can't change existing hardware and VCEI is supported indeed.] Signed-off-by: James Hogan <james.hogan@imgtec.com> Cc: linux-mips@linux-mips.org Cc: Paolo Bonzini <pbonzini@redhat.com> Cc: Gleb Natapov <gleb@kernel.org> Cc: kvm@vger.kernel.org Patchwork: https://patchwork.linux-mips.org/patch/11890/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2016-01-24MIPS: Move Cause.ExcCode trap codes to mipsregs.hJames Hogan
Move the Cause.ExcCode trap code definitions from kvm_host.h to mipsregs.h, since they describe architectural bits rather than KVM specific constants, and change the prefix from T_ to EXCCODE_.

2016-01-24MIPS: KVM: Make kvm_mips_{init,exit}() staticJames Hogan
The module init and exit functions have no need to be global, so make them static.

2016-01-24MIPS: KVM: Refactor added offsetof()sJames Hogan
When calculating the offsets into the commpage for dynamically translated mtc0/mfc0 guest instructions, multiple offsetof()s are added together to find the offset of the specific register in the mips_coproc, within the commpage. Simplify each of these cases to a single offsetof() to find the offset of the specific register within the commpage.

The function kvm_mips_host_tlb_inv_index() is unused, so drop it completely.

2016-01-24MIPS: Move definition of DC bit to mipsregs.hJames Hogan
The CAUSEB_DC and CAUSEF_DC definitions used by KVM are defined in asm/kvm_host.h, but all the other Cause register field definitions are found in asm/mipsregs.h. Lets reunite the DC bit definitions with its friends in mipsregs.h.

2016-01-24MIPS: KVM: Drop some unused definitions from kvm_host.hJames Hogan
Some definitions in the MIPS asm/kvm_host.h are completely unused, so lets drop them. MS_TO_NS is no longer used since commit e30492bbe95a ("MIPS: KVM: Rewrite count/compare timer emulation"). The others don't appear ever to have been used.
