* mm: clean up per architecture MM hook header filesLaurent Dufour2015-07-172-15/+1
| | | | | | | | | | | | | | | | | | | | | Commit 2ae416b142b6 ("mm: new mm hook framework") introduced an empty header file (mm-arch-hooks.h) for every architecture, even those which doesn't need to define mm hooks. As suggested by Geert Uytterhoeven, this could be cleaned through the use of a generic header file included via each per architecture asm/include/Kbuild file. The PowerPC architecture is not impacted here since this architecture has to defined the arch_remap MM hook.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We currently set x27 in compat_sys_sigreturn_wrapper and compat_sys_rt_sigreturn_wrapper, similarly to what we do with r8/why on 32-bit ARM, in an attempt to prevent sigreturns from being restarted. However, on arm64 we have always used pt_regs::syscallno for syscall restarting (for both native and compat tasks), and x27 is never inspected again before being overwritten in kernel_exit.

* | arm64: entry: handle debug exceptions in el*_invMark Rutland2015-07-081-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently we enable debug exceptions before reading ESR_EL1 in both el0_inv and el1_inv. If a debug exception is taken before we read ESR_EL1, the value will have been corrupted. As el*_inv is typically fatal, an intervening debug exception results in misleading debug information being logged to the console, but is not otherwise harmful. As with the other entry paths, we can use the ESR_EL1 value stashed earlier in the exception entry (in x25 for el0_sync{,_compat}, and x1 for el1_sync), giving us better error reporting in this case.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For those parts of the arm64 ACPI code that need to check GICC subtables in the MADT, use the new BAD_MADT_GICC_ENTRY macro instead of the previous BAD_MADT_ENTRY. The new macro takes into account differences in the size of the GICC subtable that the old macro did not; this caused failures even though the subtable entries are valid.

* | ACPI / ARM64: add BAD_MADT_GICC_ENTRY() macroAl Stone2015-07-071-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The BAD_MADT_ENTRY() macro is designed to work for all of the subtables of the MADT. In the ACPI 5.1 version of the spec, the struct for the GICC subtable (struct acpi_madt_generic_interrupt) is 76 bytes long; in ACPI 6.0, the struct is 80 bytes long. But, there is only one definition in ACPICA for this struct -- and that is the 6.0 version. Hence, when BAD_MADT_ENTRY() compares the struct size to the length in the GICC subtable, it fails if 5.1 structs are in use, and there are systems in the wild that have them. This patch adds the BAD_MADT_GICC_ENTRY() that checks the GICC subtable only, accounting for the difference in specification versions that are possible. The BAD_MADT_ENTRY() will continue to work as is for all other MADT subtables. This code is being added to an arm64 header file since that is currently the only architecture using the GICC subtable of the MADT. As a GIC is specific to ARM, it is also unlikely the subtable will be used elsewhere. Fixes: aeb823bbacc2 ("ACPICA: ACPI 6.0: Add changes for FADT table.")

| * ARM64 / SMP: Switch pr_err() to pr_debug() for disabled GICC entryHanjun Guo2015-07-031-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is normal that firmware presents GICC entry or entries (processors) with disabled flag in ACPI MADT, taking a system of 16 cpus for example, ACPI firmware may present 8 ebabled first with another 8 cpus disabled in MADT, the disabled cpus can be hot-added later. Firmware may also present more cpus than the hardware actually has, but disabled the unused ones, and easily enable it when the hardware has such cpus to make the firmware code scalable. So that's not an error for disabled cpus in MADT, we can switch pr_err() to pr_debug() to make the boot a little quieter by default. Since hwid for disabled cpus often are invalid, and we check invalid hwid first in the code, for use case that hot add cpus later will be filtered out and will not be counted in possible cups, so move this check before the hwid one to prepare the code to count for disabeld cpus when cpu hot-plug is introduced.

This is counter-intuitive as a clear pmd/pud cannot also be a huge pmd/pud, and it is inconsistent with at least arm and x86.

After registering NVDIMMs the NFIT driver then registers "region" devices. A libnvdimm-region defines an access mode and the boundaries of persistent memory media. A region may span multiple NVDIMMs that are interleaved by the hardware memory controller. In turn, a libnvdimm-region can be carved into a "namespace" device and bound to the PMEM or BLK driver which will attach a Linux block device (disk) interface to the memory. PMEM: Initially merged in v4.1 this driver for contiguous spans of persistent memory address ranges is re-worked to drive PMEM-namespaces emitted by the libnvdimm-core. In this update the PMEM driver, on x86, gains the ability to assert that writes to persistent memory have been flushed all the way through the caches and buffers in the platform to persistent media. See memcpy_to_pmem() and wmb_pmem(). BLK: This new driver enables access to persistent memory media through "Block Data Windows" as defined by the NFIT. The primary difference of this driver to PMEM is that only a small window of persistent memory is mapped into system address space at any given point in time. Per-NVDIMM windows are reprogrammed at run time, per-I/O, to access different portions of the media. BLK-mode, by definition, does not support DAX. BTT: This is a library, optionally consumed by either PMEM or BLK, that converts a byte-accessible namespace into a disk with atomic sector update semantics (prevents sector tearing on crash or power loss). The sinister aspect of sector tearing is that most applications do not know they have a atomic sector dependency. At least today's disk's rarely ever tear sectors and if they do one almost certainly gets a CRC error on access. NVDIMMs will always tear and always silently. Until an application is audited to be robust in the presence of sector-tearing the usage of BTT is recommended.

Mark it "reserved" and allow it to be claimed by a persistent memory device driver. This definition is in addition to the Linux kernel's existing type-12 definition that was recently added in support of shipping platforms with NVDIMM support that predate ACPI 6.0 (which now classifies type-12 as OEM reserved). Note, /proc/iomem can be consulted for differentiating legacy "Persistent Memory (legacy)" E820_PRAM vs standard "Persistent Memory" E820_PMEM.

By trial-and-error I found that these are connected to the two keys named "power" and "home" on the motherboard. Register the GPIO block and these two keys in the device tree using the PL061 GPIO driver and the generic gpio keys. - Map POWER, HOME, VOL+ and VOL- to the obvious input events. - Map RLOCK to KEY_SCREENLOCK/KEY_COFFEE unless someone can explain better what this is for. - Map the NMI button to KEY_SYSREQ as this is used like so in the SYSREQ debugging hack.
