This reverts commit 2947ba05. Dan Williams reported dax-pmem kernel warnings with the following signature: WARNING: CPU: 8 PID: 245 at lib/percpu-refcount.c:155 percpu_ref_switch_to_atomic_rcu+0x1f5/0x200 percpu ref (dax_pmem_percpu_release [dax_pmem]) <= 0 (0) after switching to atomic ... and bisected it to this commit, which suggests possible memory corruption caused by the x86 fast-GUP conversion. He also pointed out: " This is similar to the backtrace when we were not properly handling pud faults and was fixed with this commit: 220ced16 "mm: fix get_user_pages() vs device-dax pud mappings" I've found some missing _devmap checks in the generic get_user_pages_fast() path, but this does not fix the regression [...] " So given that there are known bugs, and a pretty robust looking bisection points to this commit suggesting that are unknown bugs in the conversion as well, revert it for the time being - we'll re-try in v4.13.

Commit fdd3d8ce ("x86/dump_pagetables: Add support for 5-level paging") introduced an error for dumping with only 4 levels by setting PGD_LEVEL_MULT to a wrong value.

The check between the hardware state and our shadow of it is checked in the signal handler for all bounds exceptions, even for the ones where we don't keep the shadow up2date. This is a problem because when no shadow is kept the handler fails at this point and hides the real reason of the exception. Move the check into the code-path evaluating normal bounds exceptions to prevent this.

When this function fails it just sends a SIGSEGV signal to user-space using force_sig(). This signal is missing essential information about the cause, e.g. the trap_nr or an error code.

numa_nodemask_from_meminfo() generates a nodemask of nodes which have memory according to a meminfo descriptor. The two callsites of that function both set bits in copies of the numa_nodes_parsed nodemask. In both cases, the information in supplied numa_meminfo is a subset of numa_nodes_parsed. So setting those bits again is not really necessary. Here are the three call paths which show that the supplied numa_meminfo argument describes memory regions in nodes which are already in numa_nodes_parsed: x86_numa_init() numa_init() Case 1: acpi_numa_init() acpi_parse_memory_affinity() numa_add_memblk() node_set(numa_nodes_parsed) acpi_parse_slit() acpi_numa_slit_init() numa_set_distance() numa_alloc_distance() numa_nodemask_from_meminfo() Case 2: amd_numa_init() numa_add_memblk() node_set(numa_nodes_parsed) Case 3 dummy_numa_init() node_set(numa_nodes_parsed) numa_add_memblk() numa_register_memblks() numa_nodemask_from_meminfo() Thus, in all three cases, the respective bit in numa_nodes_parsed is set, which means it is not necessary to set it again in a copy of numa_nodes_parsed. So remove that function.

Pull parisc fixes from Helge Deller: "Al Viro reported that - in case of read faults - our copy_from_user() implementation may claim to have copied more bytes than it actually did. In order to fix this bug and because of the way how gcc optimizes register usage for inline assembly in C code, we had to replace our pa_memcpy() function with a pure assembler implementation. While fixing the memcpy bug we noticed some other issues with our get_user() and put_user() functions, e.g. nested faults may return wrong data. This is now fixed by a common fixup handler for get_user/put_user in the exception handler which additionally makes generated code smaller and faster. The third patch is a trivial one-line fix for a patch which went in during 4.11-rc and which avoids stalled CPU warnings after power shutdown (for parisc machines which can't plug power off themselves). Due to the rewrite of pa_memcpy() into assembly this patch got bigger than what I wanted to have sent at this stage.

Nothing major here at all, a few things resolving reported bugs in some random serial drivers. I don't think these made the last linux-next due to me getting to them yesterday, but I am not sure, they might have snuck in. The patches only affect drivers that the maintainers of sent me these patches for, so we should be safe here :)" * tag 'tty-4.11-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty: tty: pl011: fix earlycon work-around for QDF2400 erratum 44 serial: 8250_EXAR: fix duplicate Kconfig text and add missing help text tty/serial: atmel: fix TX path in atmel_console_write() tty/serial: atmel: fix race condition (TX+DMA) serial: mxs-auart: Fix baudrate calculation

Pull ACPI fixes from Rafael Wysocki: "These fix two issues related to IOAPIC hotplug, an overzealous build optimization that prevents the function graph tracer from working with the ACPI subsystem correctly and an RCU synchronization issue in the ACPI APEI code. Specifics: - drop the unconditional setting of the '-Os' gcc flag from the ACPI Makefile to make the function graph tracer work correctly with the ACPI subsystem (Josh Poimboeuf). - add missing synchronize_rcu() to ghes_remove() which removes an element from an RCU-protected list, but fails to synchronize it properly afterward (James Morse). - fix two problems related to IOAPIC hotplug, a local variable initialization in setup_res() and the creation of platform device objects for IO(x)APICs which are (a) unused and (b) leaked on hot-removal (Joerg Roedel)" * tag 'acpi-4.11-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ACPI: Fix incompatibility with mcount-based function graph tracing ACPI / APEI: Add missing synchronize_rcu() on NOTIFY_SCI removal ACPI: Do not create a platform_device for IOAPIC/IOxAPIC ACPI: ioapic: Clear on-stack resource before using it

Pull power management fixes from Rafael Wysocki: "These fix a cpufreq core issue with the initialization of the cpufreq sysfs interface and a cpuidle powernv driver initialization issue. Specifics: - symbolic links from CPU directories to the corresponding cpufreq policy directories in sysfs are not created during initialization in some cases which confuses user space, so prevent that from happening (Rafael Wysocki). - the powernv cpuidle driver fails to pass a correct cpumaks to the cpuidle core in some cases which causes subsequent failures to occur, so fix it (Vaidyanathan Srinivasan)" * tag 'pm-4.11-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: cpuidle: powernv: Pass correct drv->cpumask for registration cpufreq: Fix creation of symbolic links to policy directories

The work-around for the Qualcomm Datacenter Technologies QDF2400 erratum 44 sets the "qdf2400_e44_present" global variable if the work-around is needed. However, this check does not happen until after earlycon is initialized, which means the work-around is not used, and the console hangs as soon as it displays one character.

kbuild test robot reported a non-static variable name collision between a staging driver and a RapidIO driver, with a generic variable name of 'dbg_level'. Both drivers should be changed so that they don't use this generic public variable name. This patch fixes the RapidIO driver but does not change the user interface (name) for the module parameter. drivers/staging/built-in.o:(.bss+0x109d0): multiple definition of `dbg_level' drivers/rapidio/built-in.o:(.bss+0x16c): first defined here Link: http://lkml.kernel.org/r/ab527fc5-aa3c-4b07-5d48-eef5de703192@infradead.orgSigned-off-by: NRandy Dunlap <rdunlap@infradead.org> Reported-by: Nkbuild test robot <fengguang.wu@intel.com> Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Cc: Matt Porter <mporter@kernel.crashing.org> Cc: Alexandre Bounine <alexandre.bounine@idt.com> Cc: Jérémy Lefaure <jeremy.lefaure@lse.epita.fr> Signed-off-by: NAndrew Morton <akpm@linux-foundation.org> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>
