2017-02-24platform/x86: intel_pmc_ipc: read s0ix residency APIShanth Murthy1-0/+6
This patch adds a new API to indicate S0ix residency in usec. It utilizes the PMC Global Control Registers (GCR) to read deep and shallow S0ix residency. PMC MMIO resources: o Lower 4kB: IPC1 (PMC inter-processor communication) interface o Upper 4kB: GCR (Global Control Registers) This enables the power management framework to take corrective actions when the platform fails to enter S0ix after kernel freeze as part of the suspend to idle flow. (echo freeze > /sys/power/state). This is expected to be used with a S0ix failsafe framework such as: <https://lwn.net/Articles/689505/> [rajneesh: folded in "fix division in 32-bit case" from Andy Shevchenko] Signed-off-by: Rajneesh Bhardwaj <rajneesh.bhardwaj@intel.com> Signed-off-by: Shanth Murthy <shanth.murthy@intel.com> [andy: fixed kbuild error, removed "total" from variables, fixed macro] Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com>

2017-02-24userfaultfd: non-cooperative: add event for memory unmapsMike Rapoport4-5/+5
When a non-cooperative userfaultfd monitor copies pages in the background, it may encounter regions that were already unmapped. Addition of UFFD_EVENT_UNMAP allows the uffd monitor to track precisely changes in the virtual memory layout. Since there might be different uffd contexts for the affected VMAs, we first should create a temporary representation for the unmap event for each uffd context and then notify them one by one to the appropriate userfault file descriptors. The event notification occurs after the mmap_sem has been released.

2017-02-24mm, x86: add support for PUD-sized transparent hugepagesMatthew Wilcox10-0/+251
The current transparent hugepage code only supports PMDs. This patch adds support for transparent use of PUDs with DAX. It does not include support for anonymous pages. x86 support code also added. Most of this patch simply parallels the work that was done for huge PMDs. The only major difference is how the new ->pud_entry method in mm_walk works. The ->pmd_entry method replaces the ->pte_entry method, whereas the ->pud_entry method works along with either ->pmd_entry or ->pte_entry. The pagewalk code takes care of locking the PUD before calling ->pud_walk, so handlers do not need to worry whether the PUD is stable.

Originally openrisc spec 0 specified that r0 would be wired to ground. This is no longer the case. r0 is not guaranteed to be 0 at init, so we need to initialize it to 0 before using it. Also, if we are clearing r0 we cant use r0 to clear itself. Change the the CLEAR_GPR macro to use movhi for clearing.

2017-02-25openrisc: Add optimized memcpy routineStafford Horne4-2/+128
The generic memcpy routine provided in kernel does only byte copies. Using word copies we can lower boot time and cycles spend in memcpy quite significantly. Booting on my de0 nano I see boot times go from 7.2 to 5.6 seconds. The avg cycles in memcpy during boot go from 6467 to 1887. I tested several algorithms (see code in previous patch mails) The implementations I tested and avg cycles: - Word Copies + Loop Unrolls + Non Aligned 1882 - Word Copies + Loop Unrolls 1887 - Word Copies 2441 - Byte Copies + Loop Unrolls 6467 - Byte Copies 7600 In the end I ended up going with Word Copies + Loop Unrolls as it provides best tradeoff between simplicity and boot speedups.

2017-02-24s390/crypt: Add protected key AES moduleMartin Schwidefsky3-2/+633
This patch introduces a new in-kernel-crypto blockcipher called 'paes' which implements AES with protected keys. The paes blockcipher can be used similar to the aes blockcipher but uses secure key material to derive the working protected key and so offers an encryption implementation where never a clear key value is exposed in memory. The paes module is only available for the s390 platform providing a minimal hardware support of CPACF enabled with at least MSA level 3. Upon module initialization these requirements are checked. Includes additional contribution from Harald Freudenberger. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
