Pull MIPS fixes from Ralf Baechle: "Another round of MIPS fixes for 4.5: - Fix JZ4780 build with DEBUG_ZBOOT and MACH_JZ4780 - Fix build with DEBUG_ZBOOT and MACH_JZ4780 - Fix issue with uninitialised temp_foreign_map - Fix awk regex compile failure with certain versions of awk.

MIPS: smp.c: Fix uninitialised temp_foreign_map

2016-03-13T09:59:19Z

When calculate_cpu_foreign_map() recalculates the cpu_foreign_map cpumask it uses the local variable temp_foreign_map without initialising it to zero. Since the calculation only ever sets bits in this cpumask any existing bits at that memory location will remain set and find their way into cpu_foreign_map too. This could potentially lead to cache operations suboptimally doing smp calls to multiple VPEs in the same core, even though the VPEs share primary caches. Therefore initialise temp_foreign_map using cpumask_clear() before use.

MIPS: Fix build error when SMP is used without GIC

2016-03-13T09:56:48Z

The MIPS_GIC_IPI should only be selected when MIPS_GIC is also selected, otherwise it results in a compile error. smp-gic.c uses some functions from include/linux/irqchip/mips-gic.h like plat_ipi_call_int_xlate() which are only added to the header file when MIPS_GIC is set. The Lantiq SoC does not use the GIC, but supports SMP. The calls top the functions from smp-gic.c are already protected by some #ifdefs The first part of this was introduced in commit 72e20142b2bf ("MIPS: Move GIC IPI functions out of smp-cmp.c") Signed-off-by: Hauke Mehrtens Cc: Paul Burton Cc: stable@vger.kernel.org # v3.15+ Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/12774/ Signed-off-by: Ralf Baechle

ld-version: Fix awk regex compile failure

2016-03-13T09:54:42Z

The ld-version.sh script fails on some versions of awk with the following error, resulting in build failures for MIPS: awk: scripts/ld-version.sh: line 4: regular expression compile failed (missing '(') This is due to the regular expression ".*)", meant to strip off the beginning of the ld version string up to the close bracket, however brackets have a meaning in regular expressions, so lets escape it so that awk doesn't expect a corresponding open bracket.

MIPS: Fix build with DEBUG_ZBOOT and MACH_JZ4780

2016-03-13T09:50:46Z

Ingenic SoC declares ZBOOT support, but debug definitions are missing for MACH_JZ4780 resulting in a build failure when DEBUG_ZBOOT is set. The UART addresses are same as with JZ4740, so fix by covering JZ4780 with those as well.

Pull block merge fix from Jens Axboe. This fixes the block segment counting bug and resulting sg overrun reported by Kent Overstreet, introduced with the last block pull. * 'for-linus' of git://git.kernel.dk/linux-block: block: don't optimize for non-cloned bio in bio_get_last_bvec()

Pull x86 fixes from Ingo Molnar: "This fixes 3 FPU handling related bugs, an EFI boot crash and a runtime warning. The EFI fix arrived late but I didn't want to delay it to after v4.5 because the effects are pretty bad for the systems that are affected by it" [ Actually, I don't think the EFI fix really matters yet, because we haven't switched to the separate EFI page tables in mainline yet ] * 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/efi: Fix boot crash by always mapping boot service regions into new EFI page tables x86/fpu: Fix eager-FPU handling on legacy FPU machines x86/delay: Avoid preemptible context checks in delay_mwaitx() x86/fpu: Revert ("x86/fpu: Disable AVX when eagerfpu is off") x86/fpu: Fix 'no387' regression

Pull SCSI target bug fix from Nicholas Bellinger: "Here is an outstanding target-core bug-fix for v4.5 code." This patch addresses a recent Task Management (TMR) regression related to larger set of multi-port LUN_RESET bug-fixes in v4.5-rc5. It drops a left-over target_put_sess_cmd() of se_cmd->cmd_kref within ABORT_TASK failure path, once a se_cmd descriptor has already completed posting response to fabric driver logic, and must be skipped during normal ABORT_TASK se_cmd->tag lookup" * git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending: target: Drop incorrect ABORT_TASK put for completed commands

block: don't optimize for non-cloned bio in bio_get_last_bvec()

2016-03-12T21:12:10Z

For !BIO_CLONED bio, we can use .bi_vcnt safely, but it doesn't mean we can just simply return .bi_io_vec[.bi_vcnt - 1] because the start postion may have been moved in the middle of the bvec, such as splitting in the middle of bvec.
