2022-08-30serial: fsl_lpuart: Remove custom frame size calculationIlpo Järvinen
The number of bits can be calculated using tty_get_frame_size(), no need for the driver to do it on its own. Change bits to unsigned and baud too since we're touching the declarations line anyway (the respective core functions are typed unsigned).

2022-08-30serial: cpm_uart: Remove custom frame size calculationIlpo Järvinen
The number of bits can be calculated using helpers in core, no need for the driver to do it on its own. The mode register is programmed with frame bits minus 1, rearrange the comments related to that "feature" closer to the actual write.

2022-08-30serial: ucc_uart: Remove custom frame size calculationIlpo Järvinen
The number of bits can be calculated using tty_get_frame_size(), no need for the driver to do it on its own. Also remove a comment on number of bits that doesn't match the code nor the comment on ucc_uart_pram's rx_length ("minus 1" part differs). That comment seems a verbatim copy of that in cpm_uart/cpm_uart_core.c anyway so perhaps it was just copied over w/o much thinking.

2022-08-30termios: get rid of stray asm/termios.h include in n_hdlc.cAl Viro
that's the only one outside of include/uapi/linux/termios.h and it's not even needed there - we have linux/tty.h already pulled and that pulls linux/termios.h Normally I would not consider that a sufficient reason, but there's a plenty of linux/tty.h users, and this is the only one that follows that with asm/termios.h. The situation with termios.h is genuinely convoluted, and this complicates it for no good reason.

2022-08-30tty: serial: meson: Use devm_clk_get_enabled() helperChristophe JAILLET
The devm_clk_get_enabled() helper: - calls devm_clk_get() - calls clk_prepare_enable() and registers what is needed in order to call clk_disable_unprepare() when needed, as a managed resource. This simplifies the code, the error handling paths and avoid the need of a dedicated function used with devm_add_action_or_reset(). That said, meson_uart_probe_clock() is now more or less the same as devm_clk_get_enabled(), so use this function directly instead. This also fixes an (unlikely) unchecked devm_add_action_or_reset() error. Based on my test with allyesconfig, this reduces the .o size from: text data bss dec hex filename 16350 5016 128 21494 53f6 drivers/tty/serial/meson_uart.o down to: 15415 4784 128 20327 4f67 drivers/tty/serial/meson_uart.o Reviewed-by: Neil Armstrong <narmstrong@baylibre.com> Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Link: https://lore.kernel.org/r/3f18638cb3cf08ed8817addca1402ed5e3bd3602.1661328361.git.christophe.jaillet@wanadoo.fr Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

Now go find false sharing on ARM64 (at least Neoverse) as well! - Refactor the JSON processing, making the output more compact and thus reducing the size of the resulting perf binary - Improvements for 'perf offcpu' profiling, including tracking child processes - Update Intel JSON metrics and events files for broadwellde, broadwellx, cascadelakex, haswellx, icelakex, ivytown, jaketown, knightslanding, sapphirerapids, skylakex and snowridgex - Add 'perf stat' JSON output and a 'perf test' entry for it - Ignore memfd and anonymous mmap events if jitdump present - Refactor 'perf test' shell tests allowing subdirs - Fix an error handling path in 'parse_perf_probe_command()' - Fixes for the guest Intel PT tracing patchkit in the 1st batch of this merge window - Print debuginfod queries if -v option is used, to explain delays in processing when debuginfo servers are enabled to fetch DSOs with richer symbol tables - Improve error message for 'perf record -p not_existing_pid' - Fix openssl and libbpf feature detection - Add PMU pai_crypto event description for IBM z16 on 'perf list' - Fix typos and duplicated words on comments in various places * tag 'perf-tools-fixes-for-v6.0-2022-08-13' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux: (81 commits) perf test: Refactor shell tests allowing subdirs perf vendor events: Update events for snowridgex perf vendor events: Update events and metrics for skylakex perf vendor events: Update metrics for sapphirerapids perf vendor events: Update events for knightslanding perf vendor events: Update metrics for jaketown perf vendor events: Update metrics for ivytown perf vendor events: Update events and metrics for icelakex perf vendor events: Update events and metrics for haswellx perf vendor events: Update events and metrics for cascadelakex perf vendor events: Update events and metrics for broadwellx perf vendor events: Update metrics for broadwellde perf jevents: Fold strings optimization perf jevents: Compress the pmu_events_table perf metrics: Copy entire pmu_event in find metric perf pmu-events: Hide the pmu_events perf pmu-events: Don't assume pmu_event is an array perf pmu-events: Move test events/metrics to JSON perf test: Use full metric resolution perf pmu-events: Hide pmu_events_map ...

git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux Pull powerpc fixes from Michael Ellerman: - Ensure we never emit lwarx with EH=1 on 32-bit, because some 32-bit CPUs trap on it rather than ignoring it as they should. - Fix ftrace when building with clang, which was broken by some refactoring. - A couple of other minor fixes.

2022-08-13afs: Enable multipage folio supportDavid Howells
Enable multipage folio support for the afs filesystem. Support has already been implemented in netfslib, fscache and cachefiles and in most of afs, but I've waited for Matthew Wilcox's latest folio changes. Note that it does require a change to afs_write_begin() to return the correct subpage. This is a "temporary" change as we're working on getting rid of the need for ->write_begin() and ->write_end() completely, at least as far as network filesystems are concerned - but it doesn't prevent afs from making use of the capability.
