2017-07-06kernel/extable.c: mark core_kernel_text notraceMarcin Nowakowski
core_kernel_text is used by MIPS in its function graph trace processing, so having this method traced leads to an infinite set of recursive calls such as: Call Trace: ftrace_return_to_handler+0x50/0x128 core_kernel_text+0x10/0x1b8 prepare_ftrace_return+0x6c/0x114 ftrace_graph_caller+0x20/0x44 return_to_handler+0x10/0x30 return_to_handler+0x0/0x30 return_to_handler+0x0/0x30 ftrace_ops_no_ops+0x114/0x1bc core_kernel_text+0x10/0x1b8 core_kernel_text+0x10/0x1b8 core_kernel_text+0x10/0x1b8 ftrace_ops_no_ops+0x114/0x1bc core_kernel_text+0x10/0x1b8 prepare_ftrace_return+0x6c/0x114 ftrace_graph_caller+0x20/0x44 (...)

2017-07-06compiler, clang: always inline when CONFIG_OPTIMIZE_INLINING is disabledDavid Rientjes
The motivation for commit abb2ea7dfd82 ("compiler, clang: suppress warning for unused static inline functions") was to suppress clang's warnings about unused static inline functions. For configs without CONFIG_OPTIMIZE_INLINING enabled, such as any non-x86 architecture, `inline' in the kernel implies that __attribute__((always_inline)) is used. Some code depends on that behavior, see https://lkml.org/lkml/2017/6/13/918: net/built-in.o: In function `__xchg_mb': arch/arm64/include/asm/cmpxchg.h:99: undefined reference to `__compiletime_assert_99' arch/arm64/include/asm/cmpxchg.h:99: undefined reference to `__compiletime_assert_99 The full fix would be to identify these breakages and annotate the functions with __always_inline instead of `inline'. But since we are late in the 4.12-rc cycle, simply carry forward the forced inlining behavior and work toward moving arm64, and other architectures, toward CONFIG_OPTIMIZE_INLINING behavior.

2017-07-06genirq: Allow to pass the IRQF_TIMER flag with percpu irq requestDaniel Lezcano
The irq timings infrastructure tracks when interrupts occur in order to statistically predict te next interrupt event. There is no point to track timer interrupts and try to predict them because the next expiration time is already known. This can be avoided via the IRQF_TIMER flag which is passed by timer drivers in request_irq(). It marks the interrupt as timer based which alloes to ignore these interrupts in the timings code. Per CPU interrupts which are requested via request_percpu_+irq() have no flag argument, so marking per cpu timer interrupts is not possible and they get tracked pointlessly. Add __request_percpu_irq() as a variant of request_percpu_irq() with a flags argument and make request_percpu_irq() an inline wrapper passing flags = 0. The flag parameter is restricted to IRQF_TIMER as all other IRQF_ flags make no sense for per cpu interrupts. The next step is to convert all existing users of request_percpu_irq() and then remove the wrapper and the underscores.

2017-07-06vrf: fix bug_on triggered by rx when destroying a vrfNikolay Aleksandrov
When destroying a VRF device we cleanup the slaves in its ndo_uninit() function, but that causes packets to be switched (skb->dev == vrf being destroyed) even though we're pass the point where the VRF should be receiving any packets while it is being dismantled. This causes a BUG_ON to trigger if we have raw sockets (trace below). The reason is that the inetdev of the VRF has been destroyed but we're still sending packets up the stack with it, so let's free the slaves in the dellink callback as David Ahern suggested. Note that this fix doesn't prevent packets from going up when the VRF device is admin down. [ 35.631371] ------------[ cut here ]------------ [ 35.631603] kernel BUG at net/ipv4/fib_frontend.c:285!

2017-07-06block: Fix __blkdev_issue_zeroout loopDamien Le Moal
The BIO issuing loop in __blkdev_issue_zeroout() is allocating BIOs with a maximum number of bvec (pages) equal to min(nr_sects, (sector_t)BIO_MAX_PAGES) This works since the requested number of bvecs will always be limited to the absolute maximum number supported (BIO_MAX_PAGES), but this is ineficient as too many bvec entries may be requested due to the different units being used in the min() operation (number of sectors vs number of pages). To fix this, introduce the helper __blkdev_sectors_to_bio_pages() to correctly calculate the number of bvecs for zeroout BIOs as the issuing loop progresses. The calculation is done using consistent units and makes sure that the number of pages return is at least 1 (for cases where the number of sectors is less that the number of sectors in a page). Also remove a trailing space after the bit shift in the internal loop min() call.

2017-07-06pwm: meson: Improve PWM calculation precisionJerome Brunet
When using input clocks with high rates, such as clk81 (166MHz), the fin_ns = NSEC_PER_SEC / fin_freq can introduce a significant error. Ex: fin_freq = 166666667, NSEC_PER_SEC = 1000000000 fin_ns = 5,9999999 which is, of course, rounded down to 5. This introduces an error of ~20% on the period requested from the PWM. This patch uses ps instead of ns (and 64 bit integers) to perform the calculation. This should give a good enough precision.

2017-07-06net/mlx5e: Initialize CEE's getpermhwaddr address buffer to 0xffHuy Nguyen
Latest change in open-lldp code uses bytes 6-11 of perm_addr buffer as the Ethernet source address for the host TLV packet. Since our driver does not fill these bytes, they stay at zero and the open-lldp code ends up sending the TLV packet with zero source address and the switch drops this packet. The fix is to initialize these bytes to 0xff. The open-lldp code considers 0xff:ff:ff:ff:ff:ff as the invalid address and falls back to use the host's mac address as the Ethernet source address.
