cxl: Route eeh events to all slices for pci_channel_io_perm_failure state

2017-03-20T09:19:36Z

Fix a boundary condition where in some cases an eeh event with state == pci_channel_io_perm_failure wont be passed on to a driver attached to the virtual PCI device associated with a slice. This will happen in case the slice just before (n-1) doesn't have any vPHB bus associated with it, that results in an early return from cxl_pci_error_detected() callback. With state == pci_channel_io_perm_failure, the adapter will be removed irrespective of the return value of cxl_vphb_error_detected(). So we now always return PCI_ERS_RESULT_DISCONNECTED for this case i.e even if the AFU isn't using a vPHB (currently returns PCI_ERS_RESULT_NONE).

vmw_vmci: handle the return value from pci_alloc_irq_vectors correctly

2017-03-16T08:32:21Z

It returns the number of vectors allocated when successful, so check for a negative error only. Fixes: 3bb434cd ("vmw_vmci: switch to pci_irq_alloc_vectors") Signed-off-by: Christoph Hellwig Reported-by: Loïc Yhuel Signed-off-by: Greg Kroah-Hartman

mei: don't wait for os version message reply

2017-03-16T01:47:53Z

The driver still struggles with firmwares that do not replay to the OS version request. It is safe not waiting for the replay. First, the driver doesn't do anything with the replay second the connection is closed immediately, hence the packet will be just safely discarded in case it is received and last the driver won't get stuck if the firmware won't reply.

mei: fix deadlock on mei reset

2017-03-16T01:47:53Z

This patch fixes 'mei: synchronize irq before initiating a reset' The patch had introduced a deadlock between irq thread and mei_reset() as they are both holding the same device lock. ---> device_lock: mei_reset() <---- interrupt thread device_lock ---> synchornize_irq() wait on interrupt thread == (dead lock) The fix is to call synchronize_irq prior to call locked mei_reset function.

mm: convert generic code to 5-level paging

Convert all non-architecture-specific code to 5-level paging. It's mostly mechanical adding handling one more page table level in places where we deal with pud_t. Signed-off-by: Kirill A. Shutemov Acked-by: Michal Hocko Signed-off-by: Linus Torvalds

Pull sched.h split-up from Ingo Molnar: "The point of these changes is to significantly reduce the header footprint, to speed up the kernel build and to have a cleaner header structure. After these changes the new 's typical preprocessed size goes down from a previous ~0.68 MB (~22K lines) to ~0.45 MB (~15K lines), which is around 40% faster to build on typical configs. Not much changed from the last version (-v2) posted three weeks ago: I eliminated quirks, backmerged fixes plus I rebased it to an upstream SHA1 from yesterday that includes most changes queued up in -next plus all sched.h changes that were pending from Andrew. I've re-tested the series both on x86 and on cross-arch defconfigs, and did a bisectability test at a number of random points. I tried to test as many build configurations as possible, but some build breakage is probably still left - but it should be mostly limited to architectures that have no cross-compiler binaries available on kernel.org, and non-default configurations" * 'WIP.sched-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (146 commits) sched/headers: Clean up sched/headers: Remove #ifdefs from sched/headers: Remove the include from sched/headers, hrtimer: Remove the include from sched/headers, x86/apic: Remove the header inclusion from sched/headers, timers: Remove the include from sched/headers: Remove from sched/headers: Remove from sched/core: Remove unused prefetch_stack() sched/headers: Remove from sched/headers: Remove the 'init_pid_ns' prototype from sched/headers: Remove from sched/headers: Remove from sched/headers: Remove the runqueue_is_locked() prototype sched/headers: Remove from sched/headers: Remove from sched/headers: Remove from sched/headers: Remove from sched/headers: Remove the include from sched/headers: Remove from ...

sched/headers: Prepare to remove spurious inclusion dependencies

2017-03-02T07:42:41Z

In the following patches we are going to remove various headers from sched.h and other headers that sched.h includes. To make those patches build cleanly prepare the scene by adding dependencies to various files that learned to rely on those to-be-removed dependencies. These changes all make sense standalone: they add a header for a data type that a particular .c or .h file is using.
