Restructure the x86 sha256 glue code so we will expose sha256 transforms based on SSSE3, AVX, AVX2 or SHA-NI extension as separate individual drivers when cpu provides such support. This will make it easy for alternative algorithms to be used if desired and makes the code cleaner and easier to maintain.

This patch includes the Intel SHA Extensions optimized implementation of SHA-256 update function. This function has been tested on Broxton platform and measured a speed up of 3.6x over the SSSE3 implementiation for 4K blocks.

If we attempt to use sysfs to change the current RNG in the usual way i.e. issuing something like: `echo 8a8a000.rng > /sys/devices/virtual/misc/hw_random/rng_current` ... it will fail because the code doesn't currently take the '\n' into consideration.

In April 2009, commit d4056405 ("Driver Core: misc: add node name support for misc devices.") inadvertently changed the device node name from /dev/hw_random to /dev/hwrng. Since 6 years has passed since the change it seems unpractical to change it back, as this node name is probably considered ABI by now. So instead, we'll just change the Kconfig help to match the current situation. NB: It looks like rng-tools have already been updated.

Commit 505a666e ("writeback: plug writeback in wb_writeback() and writeback_inodes_wb()") has us holding a plug during writeback_sb_inodes, which increases the merge rate when relatively contiguous small files are written by the filesystem. It helps both on flash and spindles. For an fs_mark workload creating 4K files in parallel across 8 drives, this commit improves performance ~9% more by unplugging before calling cond_resched(). cond_resched() doesn't trigger an implicit unplug, so explicitly getting the IO down to the device before scheduling reduces latencies for anyone waiting on clean pages. It also cuts down on how often we use kblockd to unplug, which means less work bouncing from one workqueue to another. Many more details about how we got here: https://lkml.org/lkml/2015/9/11/570Signed-off-by: Chris Mason <clm@fb.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

Tyler Baker authored
The various definitions of __pfn_to_phys() have been consolidated to use a generic macro in include/asm-generic/memory_model.h. This hit mainline in the form of 012dcef3 "mm: move __phys_to_pfn and __pfn_to_phys to asm/generic/memory_model.h". When the generic macro was implemented the type cast to phys_addr_t was dropped which caused boot regressions on ARM platforms with more than 4GB of memory and LPAE enabled. It was suggested to use PFN_PHYS() defined in include/linux/pfn.h as provides the correct logic and avoids further duplication.
