2016-05-24xen/events: Don't move disabled irqsRoss Lagerwall1-2/+4
Commit ff1e22e7a638 ("xen/events: Mask a moving irq") open-coded irq_move_irq() but left out checking if the IRQ is disabled. This broke resuming from suspend since it tries to move a (disabled) irq without holding the IRQ's desc->lock. Fix it by adding in a check for disabled IRQs. The resulting stacktrace was: kernel BUG at /build/linux-UbQGH5/linux-4.4.0/kernel/irq/migration.c:31! invalid opcode: 0000 [#1] SMP Modules linked in: xenfs xen_privcmd ...

2016-05-24Xen: don't warn about 2-byte wchar_t in efiArnd Bergmann1-0/+1
The XEN UEFI code has become available on the ARM architecture recently, but now causes a link-time warning: ld: warning: drivers/xen/efi.o uses 2-byte wchar_t yet the output is to use 4-byte wchar_t; use of wchar_t values across objects may fail This seems harmless, because the efi code only uses 2-byte characters when interacting with EFI, so we don't pass on those strings to elsewhere in the system, and we just need to silence the warning. It is not clear to me whether we actually need to build the file with the -fshort-wchar flag, but if we do, then we should also pass --no-wchar-size-warning to the linker, to avoid the warning. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Reviewed-by: Stefano Stabellini <sstabellini@kernel.org> Fixes: 37060935dc04 ("ARM64: XEN: Add a function to initialize Xen specific UEFI runtime services")
2016-05-24xen/gntdev: reduce copy batch size to 16David Vrabel1-1/+1
IOCTL_GNTDEV_GRANT_COPY batches copy operations to reduce the number of hypercalls. The stack is used to avoid a memory allocation in a hot path. However, a batch size of 24 requires more than 1024 bytes of stack which in some configurations causes a compiler warning. xen/gntdev.c: In function ‘gntdev_ioctl_grant_copy’: xen/gntdev.c:949:1: warning: the frame size of 1248 bytes is larger than 1024 bytes [-Wframe-larger-than=] This is a harmless warning as there is still plenty of stack spare, but people keep trying to "fix" it. Reduce the batch size to 16 to reduce stack usage to less than 1024 bytes. This should have minimal impact on performance. Signed-off-by: David Vrabel <david.vrabel@citrix.com>

git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm Pull libnvdimm updates from Dan Williams: "The bulk of this update was stabilized before the merge window and appeared in -next. The "device dax" implementation was revised this week in response to review feedback, and to address failures detected by the recently expanded ndctl unit test suite. Not included in this pull request are two dax topic branches (dax error handling, and dax radix-tree locking). These topics were deferred to get a few more days of -next integration testing, and to coordinate a branch baseline with Ted and the ext4 tree. Vishal and Ross will send the error handling and locking topics respectively in the next few days. This branch has received a positive build result from the kbuild robot across 226 configs. Summary: - Device DAX for persistent memory: Device DAX is the device-centric analogue of Filesystem DAX (CONFIG_FS_DAX). It allows memory ranges to be allocated and mapped without need of an intervening file system. Device DAX is strict, precise and predictable. Specifically this interface: a) Guarantees fault granularity with respect to a given page size (pte, pmd, or pud) set at configuration time. b) Enforces deterministic behavior by being strict about what fault scenarios are supported. Persistent memory is the first target, but the mechanism is also targeted for exclusive allocations of performance/feature differentiated memory ranges. - Support for the HPE DSM (device specific method) command formats. This enables management of these first generation devices until a unified DSM specification materializes. - Further ACPI 6.1 compliance with support for the common dimm identifier format. - Various fixes and cleanups across the subsystem" * tag 'libnvdimm-for-4.7' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: (40 commits) libnvdimm, dax: fix deletion libnvdimm, dax: fix alignment validation libnvdimm, dax: autodetect support libnvdimm: release ida resources Revert "block: enable dax for raw block devices" /dev/dax, core: file operations and dax-mmap /dev/dax, pmem: direct access to persistent memory libnvdimm: stop requiring a driver ->remove() method libnvdimm, dax: record the specified alignment of a dax-device instance libnvdimm, dax: reserve space to store labels for device-dax libnvdimm, dax: introduce device-dax infrastructure nfit: add sysfs dimm 'family' and 'dsm_mask' attributes tools/testing/nvdimm: ND_CMD_CALL support nfit: disable vendor specific commands nfit: export subsystem ids as attributes nfit: fix format interface code byte order per ACPI6.1 nfit, libnvdimm: limited/whitelisted dimm command marshaling mechanism nfit, libnvdimm: clarify "commands" vs "_DSMs" libnvdimm: increase max envelope size for ioctl acpi/nfit: Add sysfs "id" for NVDIMM ID ...

2016-05-23x86: remove pointless uaccess_32.h complexityLinus Torvalds1-3/+1
I'm looking at trying to possibly merge the 32-bit and 64-bit versions of the x86 uaccess.h implementation, but first this needs to be cleaned up. For example, the 32-bit version of "__copy_to_user_inatomic()" is mostly the special cases for the constant size, and it's actually never relevant. Every user except for one aren't actually using a constant size anyway, and the one user that uses it is better off just using __put_user() instead. So get rid of the unnecessary complexity. [ The same cleanup should likely happen to __copy_from_user_inatomic() as well, but that one has a lot more users that I need to take a look at first ] Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2016-05-21libnvdimm, dax: fix alignment validationDan Williams1-2/+4
Testing the dax-device autodetect support revealed a probe failure with the following result: dax0.1: bad offset: 0x8200000 dax disabled The original pfn-device implementation inferred the alignment from ilog2(offset), now that the alignment is explicit the is_power_of_2() needs replacing with a real sanity check against the recorded alignment. Otherwise the alignment check is useless in the implicit case and only the minimum size of the offset matters. This self-consistency check is further validated by the probe path that will re-check that the offset is large enough to contain all the metadata required to enable the device.
