The esai_ahb clock is derived from ahb and used to provide ESAI the capability of register accessing and FSYS clock source for I2S clocks dividing. The gate bits of this esai_ahb clock are shared with the esai clock -- the baud clock, so we need to call imx_clk_gate2_shared() for these two clocks.

It's quite common on i.MX that one gate bit controls the gating of multiple clocks, i.e. this is a shared gate. The patch adds the function imx_clk_gate2_shared() for such case. The clocks controlled by the same gate bits should call this function with a pointer to a single share count variable, so that the gate bits will only be operated on the first enabling and the last disabling of these shared gate clocks. Thanks to Gerhard Sittig <gsi@denx.de> for this idea. Signed-off-by: Shawn Guo <shawn.guo@freescale.com>

The imx specific clk_gate2 always has a valid lock with the clock. So the validation on gate->lock is not really needed. Remove it. Signed-off-by: Shawn Guo <shawn.guo@freescale.com>

Shawn Guo authored
The imx clk-gate2 driver implements an i.MX specific gate clock, which has two bits controlling the gate states. While this is a completely separate gate driver from the common clk-gate one, it reuses the common clk_gate structure. Such reusing makes the extending of clk_gate2 clumsy. Let's define struct clk_gate2 on our own to make the driver independent of the common clk-gate one, and ease the clk_gate2 extending at a later time.

Will Deacon authored
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

fs_path_ensure_buf is used to make sure our path buffers for send are big enough for the path names as we construct them. The buffer size is limited to 32K by the length field in the struct. But bugs in the path construction can end up trying to build a huge buffer, and we'll do invalid memmmoves when the buffer length field wraps. This patch is step one, preventing the overflows.

Linus Torvalds authored
The mmu-gather operation 'tlb_flush_mmu()' has done two things: the actual tlb flush operation, and the batched freeing of the pages that the TLB entries pointed at. This splits the operation into separate phases, so that the forced batched flushing done by zap_pte_range() can now do the actual TLB flush while still holding the page table lock, but delay the batched freeing of all the pages to after the lock has been dropped. This in turn allows us to avoid a race condition between set_page_dirty() (as called by zap_pte_range() when it finds a dirty shared memory pte) and page_mkclean(): because we now flush all the dirty page data from the TLB's while holding the pte lock, page_mkclean() will be held up walking the (recently cleaned) page tables until after the TLB entries have been flushed from all CPU's.
