clk: Remove io.h from clk-provider.h

2019-05-15T20:21:37+00:00

Now that we've gotten rid of clk_readl() we can remove io.h from the clk-provider header and push out the io.h include to any code that isn't already including the io.h header but using things like readl/writel, etc. Found with this grep: git grep -l clk-provider.h | grep '.c$' | xargs git grep -L 'linux/io.h' | \ xargs git grep -l \ -e '\<__iowrite32_copy\>' --or \ -e '\<__ioread32_copy\>' --or \ -e '\<__iowrite64_copy\>' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\<__devm_memremap_pages\>' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\<__io_aw\>' --or \ -e '\<__io_pbw\>' --or \ -e '\<__io_paw\>' --or \ -e '\<__io_pbr\>' --or \ -e '\<__io_par\>' --or \ -e '\<__raw_readb\>' --or \ -e '\<__raw_readw\>' --or \ -e '\<__raw_readl\>' --or \ -e '\<__raw_readq\>' --or \ -e '\<__raw_writeb\>' --or \ -e '\<__raw_writew\>' --or \ -e '\<__raw_writel\>' --or \ -e '\<__raw_writeq\>' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\<__io_virt\>' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\<__ioremap\>' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' --or \ -e '\' I also reordered a couple includes when they weren't alphabetical and removed clk.h from kona, replacing it with clk-provider.h because that driver doesn't use clk consumer APIs.

xtensa: rework {CONFIG,PLATFORM}_DEFAULT_MEM_START

2018-08-20T19:28:03+00:00

Drop PLATFORM_DEFAULT_MEM_START from the platform/hardware.h headers. Provide definition of CONFIG_DEFAULT_MEM_START always, allow changing it only in noMMU configurations when PLATFORM_WANT_DEFAULT_MEM is selected. Change prompt and description so that it's clear that it controls PAGE_OFFSET and PHYS_OFFSET. Signed-off-by: Max Filippov

2018-08-20T19:27:52+00:00

Now that noMMU cache attributes are set up separately drop no longer used macro PLATFORM_DEFAULT_MEM_SIZE and config symbol CONFIG_DEFAULT_MEM_SIZE used for setting it. Signed-off-by: Max Filippov

locking/atomics: COCCINELLE/treewide: Convert trivial ACCESS_ONCE() patterns to READ_ONCE()/WRITE_ONCE()

2017-10-25T09:01:08+00:00

Please do not apply this to mainline directly, instead please re-run the coccinelle script shown below and apply its output. For several reasons, it is desirable to use {READ,WRITE}_ONCE() in preference to ACCESS_ONCE(), and new code is expected to use one of the former. So far, there's been no reason to change most existing uses of ACCESS_ONCE(), as these aren't harmful, and changing them results in churn. However, for some features, the read/write distinction is critical to correct operation. To distinguish these cases, separate read/write accessors must be used. This patch migrates (most) remaining ACCESS_ONCE() instances to {READ,WRITE}_ONCE(), using the following coccinelle script: ---- // Convert trivial ACCESS_ONCE() uses to equivalent READ_ONCE() and // WRITE_ONCE() // $ make coccicheck COCCI=/home/mark/once.cocci SPFLAGS="--include-headers" MODE=patch virtual patch @ depends on patch @ expression E1, E2; @@ - ACCESS_ONCE(E1) = E2 + WRITE_ONCE(E1, E2) @ depends on patch @ expression E; @@ - ACCESS_ONCE(E) + READ_ONCE(E) ---- Signed-off-by: Mark Rutland Signed-off-by: Paul E.
