Merge branch 'libnvdimm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm

2016-12-09T19:27:22Z

Pull libnvdimm fixes from Dan Williams: "Several fixes to the DSM (ACPI device specific method) marshaling implementation. I consider these urgent enough to send for 4.9 consideration since they fix the kernel's handling of ARS (Address Range Scrub) commands. Especially for platforms without machine-check-recovery capabilities, successful execution of ARS commands enables the platform to potentially break out of an infinite reboot problem if a media error is present in the boot path. There is also a one line fix for a device-dax read-only mapping regression. Commits 9a901f5495e2 ("acpi, nfit: fix extended status translations for ACPI DSMs") and 325896ffdf90 ("device-dax: fix private mapping restriction, permit read-only") are true regression fixes for changes introduced this cycle. Commit efda1b5d87cb ("acpi, nfit, libnvdimm: fix / harden ars_status output length handling") fixes the kernel's handling of zero-length results, this never would have worked in the past, but we only just recently discovered a BIOS implementation that emits this arguably spec non-compliant result. The remaining two commits are additional fall out from thinking through the implications of a zero / truncated length result of the ARS Status command. In order to mitigate the risk that these changes introduce yet more regressions they are backstopped by a new unit test in commit a7de92dac9f0 ("tools/testing/nvdimm: unit test acpi_nfit_ctl()") that mocks up inputs to acpi_nfit_ctl()" * 'libnvdimm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: device-dax: fix private mapping restriction, permit read-only tools/testing/nvdimm: unit test acpi_nfit_ctl() acpi, nfit: fix bus vs dimm confusion in xlat_status acpi, nfit: validate ars_status output buffer size acpi, nfit, libnvdimm: fix / harden ars_status output length handling acpi, nfit: fix extended status translations for ACPI DSMs

Revert "radix tree test suite: fix compilation"

2016-12-09T18:41:42Z

This reverts commit 53855d10f4567a0577360b6448d52a863929775b. It shouldn't have come in yet - it depends on the changes in linux-next that will come in during the next merge window. As Matthew Wilcox says, the test suite is broken with the current state without the revert. Requested-by: Matthew Wilcox Cc: Andrew Morton Signed-off-by: Linus Torvalds

radix tree test suite: fix compilation

2016-12-08T01:10:00Z

Patch "lib/radix-tree: Convert to hotplug state machine" breaks the test suite as it adds a call to cpuhp_setup_state_nocalls() which is not currently emulated in the test suite. Add it, and delete the emulation of the old CPU hotplug mechanism.

tools/testing/nvdimm: unit test acpi_nfit_ctl()

2016-12-07T01:42:36Z

A recent flurry of bug discoveries in the nfit driver's DSM marshalling routine has highlighted the fact that we do not have unit test coverage for this routine. Add a self-test of acpi_nfit_ctl() routine before probing the "nfit_test.0" device. This mocks stimulus to acpi_nfit_ctl() and if any of the tests fail "nfit_test.0" will be unavailable causing the rest of the tests to not run / fail. This unit test will also be a place to land reproductions of quirky BIOS behavior discovered in the field and ensure the kernel does not regress against implementations it has seen in practice.

objtool: Fix bytes check of lea's rex_prefix

2016-12-06T08:20:59Z

For the "lea %(rsp), %rbp" case, we check if there is a rex_prefix. But we check 'bytes' which is insn_byte_t[4] in rex_prefix (insn_field structure). Therefore, the check is always true. Instead, check 'nbytes' which is the right one. Signed-off-by: Jiri Slaby Acked-by: Josh Poimboeuf Cc: Andy Lutomirski Cc: Borislav Petkov Cc: Brian Gerst Cc: Denys Vlasenko Cc: H.
