2018-09-14xen/gntdev: fix up blockable calls to mn_invl_range_startMichal Hocko
Patch series "mmu_notifiers follow ups". Tetsuo has noticed some fallouts from 93065ac753e4 ("mm, oom: distinguish blockable mode for mmu notifiers"). One of them has been fixed and picked up by AMD/DRM maintainer [1]. XEN issue is fixed by patch 1. I have also clarified expectations about blockable semantic of invalidate_range_end. Finally the last patch removes MMU_INVALIDATE_DOES_NOT_BLOCK which is no longer used nor needed. [1] http://lkml.kernel.org/r/20180824135257.GU29735@dhcp22.suse.cz This patch (of 3): 93065ac753e4 ("mm, oom: distinguish blockable mode for mmu notifiers") has introduced blockable parameter to all mmu_notifiers and the notifier has to back off when called in !blockable case and it could block down the road. The above commit implemented that for mn_invl_range_start but both in_range checks are done unconditionally regardless of the blockable mode and as such they would fail all the time for regular calls. Fix this by checking blockable parameter as well. Once we are there we can remove the stale TODO. The lock has to be sleepable because we wait for completion down in gnttab_unmap_refs_sync.

2018-09-14xen/balloon: add runtime control for scrubbing ballooned out pagesMarek Marczykowski-Górecki
Scrubbing pages on initial balloon down can take some time, especially in nested virtualization case (nested EPT is slow). When HVM/PVH guest is started with memory= significantly lower than maxmem=, all the extra pages will be scrubbed before returning to Xen. But since most of them weren't used at all at that point, Xen needs to populate them first (from populate-on-demand pool). In nested virt case (Xen inside KVM) this slows down the guest boot by 15-30s with just 1.5GB needed to be returned to Xen. Add runtime parameter to enable/disable it, to allow initially disabling scrubbing, then enable it back during boot (for example in initramfs). Such usage relies on assumption that a) most pages ballooned out during initial boot weren't used at all, and b) even if they were, very few secrets are in the guest at that time (before any serious userspace kicks in). Convert CONFIG_XEN_SCRUB_PAGES to CONFIG_XEN_SCRUB_PAGES_DEFAULT (also enabled by default), controlling default value for the new runtime switch.

2018-09-14asm-generic: io: Fix ioport_map() for !CONFIG_GENERIC_IOMAP && ↵Andrew Murray
CONFIG_INDIRECT_PIO The !CONFIG_GENERIC_IOMAP version of ioport_map uses MMIO_UPPER_LIMIT to prevent users from making I/O accesses outside the expected I/O range - however it erroneously treats MMIO_UPPER_LIMIT as a mask which is contradictory to its other users. The introduction of CONFIG_INDIRECT_PIO, which subtracts an arbitrary amount from IO_SPACE_LIMIT to form MMIO_UPPER_LIMIT, results in ioport_map mangling the given port rather than capping it. We address this by aligning more closely with the CONFIG_GENERIC_IOMAP implementation of ioport_map by using the comparison operator and returning NULL where the port exceeds MMIO_UPPER_LIMIT. Though note that we preserve the existing behavior of masking with IO_SPACE_LIMIT such that we don't break existing buggy drivers that somehow rely on this masking.

2018-09-13mm: get rid of vmacache_flush_all() entirelyLinus Torvalds
Jann Horn points out that the vmacache_flush_all() function is not only potentially expensive, it's buggy too. It also happens to be entirely unnecessary, because the sequence number overflow case can be avoided by simply making the sequence number be 64-bit. That doesn't even grow the data structures in question, because the other adjacent fields are already 64-bit. So simplify the whole thing by just making the sequence number overflow case go away entirely, which gets rid of all the complications and makes the code faster too. Win-win.

2018-09-13socket: fix struct ifreq size in compat ioctlJohannes Berg
As reported by Reobert O'Callahan, since Viro's commit to kill dev_ifsioc() we attempt to copy too much data in compat mode, which may lead to EFAULT when the 32-bit version of struct ifreq sits at/near the end of a page boundary, and the next page isn't mapped. Fix this by passing the approprate compat/non-compat size to copy and using that, as before the dev_ifsioc() removal. This works because only the embedded "struct ifmap" has different size, and this is only used in SIOCGIFMAP/SIOCSIFMAP which has a different handler. All other parts of the union are naturally compatible. This fixes https://bugzilla.kernel.org/show_bug.cgi?id=199469.

2018-09-13drm/amdgpu: use a single linked list for amdgpu_vm_bo_baseChristian König
Instead of the double linked list. Gets the size of amdgpu_vm_pt down to 64 bytes again. We could even reduce it down to 32 bytes, but that would require some rather extreme hacks.

2018-09-13drm/amd/display: Fix pflip IRQ status after gpu reset.Andrey Grodzovsky
Problem: After GPU reset pflip completion IRQ is disabled and hence any subsequent mode set or plane update leads to hang. Fix: Unless acrtc->otg_inst is initialized to -1 during display block initializtion then durng resume from GPU reset amdgpu_irq_gpu_reset_resume_helper will override CRTC 0 pflip IRQ value with whatever value was on every other unused CRTC because dm_irq_state will do irq_source = dal_irq_type + acrtc->otg_inst where acrtc->otg_inst will be 0 for every unused CRTC.
