2018-09-18staging: vboxvideo: Skip currrent crtc when updating crtcsHans de Goede
In vbox_crtc_set_base_and_mode() we update all the crtcs when the single_framebuffer setting changes, including the one on which vbox_crtc_set_base_and_mode() was called, so we end up doing vbox_do_modeset() on it twice. This commit skips the crtc on which we are updating in the loop to update the other crtcs. This commit also removes the vbox_set_view() call from the loop, vbox_set_view() does not depend on the single_framebuffer setting and it was being called on the passed in crtc parameter and not on the crtci local iterator value (typo), so it was a no-op already.

2018-09-18staging: vboxvideo: Fix modeset / page_flip error handlingHans de Goede
The default settings for Linux vms created in VirtualBox allocate only 16M of videomem. When running fullscreen on a 1920x1080 (or bigger) monitor this is not a lot. When using GNOME3 on Wayland we have already been seeing out of video memory errors for a while now. After commit 2408898e3b6c ("staging: vboxvideo: Add page-flip support") this has become much worse as now multiple buffers are used. There is nothing we can do about there not being enough video-mem, but we should handle running out of video-mem properly, currently there are 2 problems with this: 1) vbox_crtc_mode_set() does not check if vbox_crtc_mode_set_base() fails at all and does not properly propagate the oom error. 2) vbox_crtc_do_set_base() unpins the old fb too soon: 2.1) It unpins it before pinning the new fb, so if the pinning of the new fb fails (which it will when we run out of video-mem), then we also cannot fall back to the old-fb as it has been already unpinned. We could try to re-pin it but there is no guarantee that will succeed. 2.2) It unpins it before reprogramming the hardware to scan out from the new-fb, which could lead to some ugliness where the hw is scanning out the oldfb while it is being replaced with something else. Fixing this requires to do things in this order: 1) Pin the new fb 2) Program the hw 3) Unpin the oldfb This needs to be done for both a mode_set and for a page_flip so this commit re-writes vbox_crtc_do_set_base() into vbox_crtc_set_base_and_mode() which does this in the correct order, putting the hardware programming which was duplicated between the mode_set and page_flip code inside the new function.

2018-09-17spi: add software implementation for SPI_CS_WORDDavid Lechner
This adds a default software implementation for the SPI_CS_WORD flag for controllers that don't have such a feature. The SPI_CS_WORD flag indicates that the CS line should be toggled between each word sent, not just between each transfer. The implementation works by using existing functions to split transfers into one-word-sized transfers and sets the cs_change bit for each of the new transfers.

Fixes commit 17be2a2905a6ec9aa27cd59521495e2f490d2af0 ("staging: iio: ad7606: replace range/range_available with corresponding scale"). The AD7606 devices don't have a 2.5V voltage range, they have 5V & 10V voltage range, which is selectable via the `gpio_range` descriptor. The scales also seem to have been miscomputed, because when they were applied to the raw values, the results differ from the expected values. After checking the ADC transfer function in the datasheet, these were re-computed.

Nothing that's the end of the world, but we've got a fix for PCI IO port accesses, an accidental naked "asm goto" and a fix to the vmcoreinfo PT_NOTE merged this time around which we'd like to get sorted before it becomes ABI. - Fix ioport_map() mapping the wrong physical address for some I/O BARs - Remove direct use of "asm goto", since some compilers don't like that - Ensure kimage_voffset is always present in vmcoreinfo PT_NOTE" * tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: asm-generic: io: Fix ioport_map() for !CONFIG_GENERIC_IOMAP && CONFIG_INDIRECT_PIO arm64: kernel: arch_crash_save_vmcoreinfo() should depend on CONFIG_CRASH_CORE arm64: jump_label.h: use asm_volatile_goto macro instead of "asm goto"
2018-09-14NFS: Don't open code clearing of delegation stateTrond Myklebust
Add a helper for the case when the nfs4 open state has been set to use a delegation stateid, and we want to revert to using the open stateid. Signed-off-by: Trond Myklebust <trond.myklebust@hammerspace.com> Signed-off-by: Anna Schumaker <Anna.Schumaker@Netapp.com>
2018-09-14NFSv4.1 fix infinite loop on I/O.Trond Myklebust
The previous fix broke recovery of delegated stateids because it assumes that if we did not mark the delegation as suspect, then the delegation has effectively been revoked, and so it removes that delegation irrespectively of whether or not it is valid and still in use. While this is "mostly harmless" for ordinary I/O, we've seen pNFS fail with LAYOUTGET spinning in an infinite loop while complaining that we're using an invalid stateid (in this case the all-zero stateid). What we rather want to do here is ensure that the delegation is always correctly marked as needing testing when that is the case. So we want to close the loophole offered by nfs4_schedule_stateid_recovery(), which marks the state as needing to be reclaimed, but not the delegation that may be backing it.
