The asm-generic, big-endian version of zero_bytemask creates a mask of bytes preceding the first zero-byte by left shifting ~0ul based on the position of the first zero byte. Unfortunately, if the first (top) byte is zero, the output of prep_zero_mask has only the top bit set, resulting in undefined C behaviour as we shift left by an amount equal to the width of the type. As it happens, GCC doesn't manage to spot this through the call to fls(), but the issue remains if architectures choose to implement their shift instructions differently. An example would be arch/arm/ (AArch32), where LSL Rd, Rn, #32 results in Rd == 0x0, whilst on arch/arm64 (AArch64) LSL Xd, Xn, #64 results in Xd == Xn. Rather than check explicitly for the problematic shift, this patch adds an extra shift by 1, replacing fls with __fls. Since zero_bytemask is never called with a zero argument (has_zero() is used to check the data first), we don't need to worry about calling __fls(0), which is undefined.

This merges the patch to fix possible loss of dirty bit on munmap() or madvice(DONTNEED). If there are concurrent writers on other CPU's that have the unmapped/unneeded page in their TLBs, their writes to the page could possibly get lost if a third CPU raced with the TLB flush and did a page_mkclean() before the page was fully written. Admittedly, if you unmap() or madvice(DONTNEED) an area _while_ another thread is still busy writing to it, you deserve all the lost writes you could get. But we kernel people hold ourselves to higher quality standards than "crazy people deserve to lose", because, well, we've seen people do all kinds of crazy things. So let's get it right, just because we can, and we don't have to worry about it. * safe-dirty-tlb-flush: mm: split 'tlb_flush_mmu()' into tlb flushing and memory freeing parts

Pull irq fixes from Thomas Gleixner: "A slighlty large fix for a subtle issue in the CPU hotplug code of certain ARM SoCs, where the not yet online cpu needs to setup the cpu local timer and needs to set the interrupt affinity to itself. Setting interrupt affinity to a not online cpu is prohibited and therefor the timer interrupt ends up on the wrong cpu, which leads to nasty complications. The SoC folks tried to hack around that in the SoC code in some more than nasty ways. The proper solution is to have a way to enforce the affinity setting to a not online cpu. The core patch to the genirq code provides that facility and the follow up patches make use of it in the GIC interrupt controller and the exynos timer driver. The change to the core code has no implications to existing users, except for the rename of the locked function and therefor the necessary fixup in mips/cavium. Aside of that, no runtime impact is possible, as none of the existing interrupt chips implements anything which depends on the force argument of the irq_set_affinity() callback" * 'irq-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: clocksource: Exynos_mct: Register clock event after request_irq() clocksource: Exynos_mct: Use irq_force_affinity() in cpu bringup irqchip: Gic: Support forced affinity setting genirq: Allow forcing cpu affinity of interrupts
