The difference between PINMUX_IPSR_MSEL() and PINMUX_IPSR_MODSEL_DATA() are FN_xxx order, and PINMUX_IPSR_MSEL() is used only from r8a7778. Now it r8a7778 works correctly with PINMUX_IPSR_MODSEL_DATA() order. This means we can merge PINMUX_IPSR_MSEL() and PINMUX_IPSR_MODSEL_DATA(). Current PFC driver is very difficult to read, because macro names are using different length. Especially PINMUX_IPSR_MODSEL_DATA() is well used macro PINMUX_IPSR_NOGP(ispr, ...)

When using serial port SCIFB1_B, transmit works, but nothing is received. Receive fails because the SCIFB1_SCK_B settings configure the wrong value for the sel_scifb1 field in the Module Select Register (MOD_SEL), due to an ambiguity in the R-Car M2-W and M2-N datasheets. Tested on r8a7791/koelsch using pins 53 (TXD) and 72 (RXD) on EXIO Connector A. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Acked-by: Linus Walleij <linus.walleij@linaro.org>

On platforms where the PFC/GPIO controller is instantiated from DT, the mapping between GPIOs and pins is set up using the "gpio-ranges" property in DT. Hence stop setting up the mapping from C code on DT platforms. This code is still used for SH or ARM-legacy platforms.

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.
