Pull MIPS fixes from Ralf Baechle: "Another round of MIPS fixes: - compressed boot: Ignore a generated .c file - VDSO: Fix a register clobber list - DECstation: Fix an int-handler.S CPU_DADDI_WORKAROUNDS regression - Octeon: Fix recent cleanups that cleaned away a bit too much thus breaking the arch side of the EDAC and USB drivers. - uasm: Fix duplicate const in "const struct foo const bar[]" which GCC 7.1 no longer accepts. - Fix race on setting and getting cpu_online_mask - Fix preemption issue. To do so cleanly introduce macro to get the size of L3 cache line. - Revert include cleanup that sometimes results in build error - MicroMIPS uses bit 0 of the PC to indicate microMIPS mode. Make sure this bit is set for kernel entry as well. - Prevent configuring the kernel for both microMIPS and MT. There are no such CPUs currently and thus the combination is unsupported and results in build errors. This has been sitting in linux-next for a few days and has survived automated testing by Imagination's test farm. No known regressions pending except a number of issues that crept up due to lots of people switching to GCC 7.1" * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: MIPS: Set ISA bit in entry-y for microMIPS kernels MIPS: Prevent building MT support for microMIPS kernels MIPS: PCI: Fix smp_processor_id() in preemptible MIPS: Introduce cpu_tcache_line_size MIPS: DEC: Fix an int-handler.S CPU_DADDI_WORKAROUNDS regression MIPS: VDSO: Fix clobber lists in fallback code paths Revert "MIPS: Don't unnecessarily include kmalloc.h into <asm/cache.h>."

2017-08-12drm/i915: Suppress switch_mm emission between the same aliasing_ppgttChris Wilson1-7/+8
When switching between contexts using the aliasing_ppgtt, the VM is shared. We don't need to reload the PD registers unless they are dirty. Martin Peres reported an issue that looks like corruption between Haswell context switches, bisecting to commit f9326be5f1d3 ("drm/i915: Rearrange switch_context to load the aliasing ppgtt on first use"). Switching between the same mm (the aliasing_ppgtt is used for all contexts in this case) should be a nop, but appears to trigger some side-effects in the context switch. However, as we know the switch is redundant in this case, we can skip it and continue to ignore the issue until somebody feels strong enough to investigate full-ppgtt on gen7 again! Except.. Martin was using full-ppgtt which is not supported as it doesn't work correctly yet. So whilst the bisect did yield valuable information about the failures, the fix should not have any user impact under default settings, with the exception of a slightly lower throughput on xcs as the VM would always be reloaded. v2: Also remember to set the legacy_active_context following the switch on xcs (commit e8a9c58fcd9a ("drm/i915: Unify active context tracking between legacy/execlists/guc")) Fixes: f9326be5f1d3 ("drm/i915: Rearrange switch_context to load the aliasing ppgtt on first use") Fixes: e8a9c58fcd9a ("drm/i915: Unify active context tracking between legacy/execlists/guc") Reported-by: Martin Peres <[email protected]> Signed-off-by: Chris Wilson <[email protected]> Cc: Martin Peres <[email protected]> Reviewed-by: Joonas Lahtinen <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]

Use drm_*_get() and drm_*_put() helpers instead of drm_*_reference() and drm_*_unreference() helpers. drm_*_reference() and drm_*_unreference() functions are just compatibility alias for drm_*_get() and drm_*_put() and should not be used by new code. So convert all users of compatibility functions to use the new APIs.

2017-08-11drm/i915/fbc: only update no_fbc_reason when activeDaniel Vetter1-1/+3
In our snb farm in CI we have plenty of underruns, but not enough stolen memory to enable fbc. Which means every time there's an underrun the no_fbc_reason swichtes to something that makes kms_frontbuffer_tracking fail instead of skip, adding massive amounts of additional noise to igt test runs. Make sure we don't try to disable fbc when it's off already. v2: Squash in additional WARN_ON suggestion from Chris.

Commit c54451a "iommu/arm-smmu: Fix the error path in arm_smmu_add_device" removed fwspec assignment in legacy_binding path as redundant which is wrong. It needs to be updated after fwspec initialisation in arm_smmu_register_legacy_master() as it is dereferenced later. Without this there is a NULL-pointer dereference panic during boot on some hosts.

2017-08-11xen/events: Fix interrupt lost during irq_disable and irq_enableLiu Shuo1-1/+1
Here is a device has xen-pirq-MSI interrupt. Dom0 might lost interrupt during driver irq_disable/irq_enable. Here is the scenario, 1. irq_disable -> disable_dynirq -> mask_evtchn(irq channel) 2. dev interrupt raised by HW and Xen mark its evtchn as pending 3. irq_enable -> startup_pirq -> eoi_pirq -> clear_evtchn(channel of irq) -> clear pending status 4. consume_one_event process the irq event without pending bit assert which result in interrupt lost once 5. No HW interrupt raising anymore. Now use enable_dynirq for enable_pirq of xen_pirq_chip to remove eoi_pirq when irq_enable.

2017-08-11xen: avoid deadlock in xenbusJuergen Gross1-1/+2
When starting the xenwatch thread a theoretical deadlock situation is possible: xs_init() contains: task = kthread_run(xenwatch_thread, NULL, "xenwatch"); if (IS_ERR(task)) return PTR_ERR(task); xenwatch_pid = task->pid; And xenwatch_thread() does: mutex_lock(&xenwatch_mutex); ... event->handle->callback(); ... mutex_unlock(&xenwatch_mutex); The callback could call unregister_xenbus_watch() which does: ... if (current->pid != xenwatch_pid) mutex_lock(&xenwatch_mutex); ... In case a watch is firing before xenwatch_pid could be set and the callback of that watch unregisters a watch, then a self-deadlock would occur. Avoid this by setting xenwatch_pid in xenwatch_thread().

2017-08-11xen: fix hvm guest with kaslr enabledJuergen Gross1-2/+14
A Xen HVM guest running with KASLR enabled will die rather soon today because the shared info page mapping is using va() too early. This was introduced by commit a5d5f328b0e2baa5ee7c119fd66324eb79eeeb66 ("xen: allocate page for shared info page from low memory"). In order to fix this use early_memremap() to get a temporary virtual address for shared info until va() can be used safely.

2017-08-11drm: Only lastclose on unload for legacy driversDaniel Vetter1-1/+2
The only thing modern drivers are supposed to do in lastclose is restore the fb emulation state. Which is entirely optional, and there's really no reason to do that. So restrict it to legacy drivers (where the driver cleanup essentially happens in lastclose). This will also allow us to share the unregister function with drm_dev_unplug().

So I think there's 3 cases: - Trying to unload the module. You can't do that while anyone has the fd still open, so lastclose is guaranteeed to run. - Forcefully unbinding the driver through sysfs. Not any better, since the can_switch stuff checks for the open count, and so will delay the delayed switch no matter what. - Actual hotremoval: a) not implemented since none of the drivers taking part in vgaswitcheroo correctly unplug the drm device and b) you can't hotremove a chip from a laptop. v2: Extend commit message with m-l discussion.
