If the load unaligned zeropad test takes a SEGV which can't be handled, we increment segv_error, print the offending NIP and then return without taking any further action. In almost all cases this means we'll just take the SEGV again, and loop eternally spamming the console. Instead just abort(), it's a fatal error in the test. The test harness will notice that the child died and print a nice message for us. Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>

Exception handlers are aligned to 128 bytes (L1 cache) on 64s, which is overkill. It can reduce the icache footprint of any individual exception path. However taken as a whole, the expansion in icache footprint seems likely to be counter-productive and cause more total misses. Create IFETCH_ALIGN_SHIFT/BYTES, which should give optimal ifetch alignment with much more reasonable alignment. This saves 1792 bytes from head_64.o text with an allmodconfig build. Other subarchitectures should define appropriate IFETCH_ALIGN_SHIFT values if this becomes more widely used.

Merge media fixes from Mauro Carvalho Chehab: "This contains two patches fixing problems with my patch series meant to make USB drivers to work again after the DMA on stack changes. The last patch on this series is actually not related to DMA on stack. It solves a longstanding bug affecting module unload, causing module_put() to be called twice. It was reported by the user who reported and tested the issues with the gp8psk driver with the DMA fixup patches. As we're late at -rc cycle, maybe you prefer to not apply it right now. If this is the case, I'll add to the pile of patches for 4.10. Exceptionally this time, I'm sending the patches via e-mail, because I'm on another trip, and won't be able to use the usual procedure until Monday. Also, it is only three patches, and you followed already the discussions about the first one" * emailed patches from Mauro Carvalho Chehab <mchehab@osg.samsung.com>: gp8psk: Fix DVB frontend attach gp8psk: fix gp8psk_usb_in_op() logic dvb-usb: move data_mutex to struct dvb_usb_device

The ns->lba_shift assumes its value to be the logarithmic of the LA size. A previous patch duplicated the lba_shift calculation into lightnvm. It prematurely also subtracted a 512byte shift, which commonly is applied per-command. The 512byte shift being subtracted twice led to data loss when restoring the logical to physical mapping table from device and when issuing I/O commands using rrpc. Fix offset by removing the 512byte shift subtraction when calculating lba_shift.

Pull pin control fixes from Linus Walleij: "All is about drivers, no core business going on. - Fix a host of runtime problems with the Intel Cherryview driver: suspend/resume needs to be marshalled properly, and strange effects from BIOS interaction during suspend/resume need to be dealt with. - A single bit was being set wrong in the Aspeed driver. - Fix an iProc probe ordering fallout resulting from v4.9 refactorings for bus population. - Do not specify a default trigger in the ST Micro cascaded GPIO IRQ controller: the kernel will moan. - Make IRQs optional altogether on the STM32 driver, it turns out not all systems have them or want them. - Fix a re-probe bug in the i.MX driver, it will eventually crash if probed repeatedly, not good" * tag 'pinctrl-v4.9-3' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: pinctrl-aspeed-g5: Never set SCU90[6] pinctrl: cherryview: Prevent possible interrupt storm on resume pinctrl: cherryview: Serialize register access in suspend/resume pinctrl: imx: reset group index on probe pinctrl: stm32: move gpio irqs binding to optional pinctrl: stm32: remove dependency with interrupt controller pinctrl: st: don't specify default interrupt trigger pinctrl: iproc: Fix iProc and NSP GPIO support

Merge fixes for -Wmaybe-uninitialized from Arnd Bergmann: "It took a while for some patches to make it into mainline through maintainer trees, but the 28-patch series is now reduced to 10, with one tiny patch added at the end. Aside from patches that are no longer required, I did these changes compared to version 1: - Dropped "iio: maxim_thermocouple: detect invalid storage size in read()", which is currently in linux-next as commit 32cb7d27. This is the only remaining warning I see for a couple of corner cases (kbuild bot reports it on blackfin, kernelci bot and arm-soc bot both report it on arm64) - Dropped "brcmfmac: avoid maybe-uninitialized warning in brcmf_cfg80211_start_ap", which is currently in net/master merge pending. - Dropped two x86 patches, "x86: math-emu: possible uninitialized variable use" and "x86: mark target address as output in 'insb' asm" as they do not seem to trigger for a default build, and I got no feedback on them. Both of these are ancient issues and seem harmless, I will send them again to the x86 maintainers once the rest is merged. - Dropped "rbd: false-postive gcc-4.9 -Wmaybe-uninitialized" based on feedback from Ilya Dryomov, who already has a different fix queued up for v4.10. The kbuild bot reports this as a warning for xtensa. - Replaced "crypto: aesni: avoid -Wmaybe-uninitialized warning" with a simpler patch, this one always triggers but my first solution would not be safe for linux-4.9 any more at this point. I'll follow up with the larger patch as a cleanup for 4.10. - Replaced "dib0700: fix nec repeat handling" with a better one, contributed by Sean Young" * -Wmaybe-uninitialized fixes: Kbuild: enable -Wmaybe-uninitialized warnings by default pcmcia: fix return value of soc_pcmcia_regulator_set infiniband: shut up a maybe-uninitialized warning crypto: aesni: shut up -Wmaybe-uninitialized warning rc: print correct variable for z8f0811 dib0700: fix nec repeat handling s390: pci: don't print uninitialized data for debugging nios2: fix timer initcall return value x86: apm: avoid uninitialized data NFSv4.1: work around -Wmaybe-uninitialized warning Kbuild: enable -Wmaybe-uninitialized warning for "make W=1"

Pull Ceph fixes from Ilya Dryomov: "Ceph's ->read_iter() implementation is incompatible with the new generic_file_splice_read() code that went into -rc1. Switch to the less efficient default_file_splice_read() for now; the proper fix is being held for 4.10.

Previously the warnings were added back at the W=1 level and above, this now turns them on again by default, assuming that we have addressed all warnings and again have a clean build for v4.10. I found a number of new warnings in linux-next already and submitted bugfixes for those. Hopefully they are caught by the 0day builder in the future as soon as this patch is merged.
