2018-07-31hwmon: (ibmpowernv) Add attributes to enable/disable sensor groupsShilpasri G Bhat1-2/+41
OPAL firmware provides the facility for some groups of sensors to be enabled/disabled at runtime to give the user the option of using the system resources for collecting these sensors or not. For example, on POWER9 systems, the On Chip Controller (OCC) gathers various system and chip level sensors and maintains their values in main memory. This patch provides support for enabling/disabling the sensor groups like power, temperature, current and voltage.

2018-06-28Revert changes to convert to ->poll_mask() and aio IOCB_CMD_POLLLinus Torvalds2-19/+1
The poll() changes were not well thought out, and completely unexplained. They also caused a huge performance regression, because "->poll()" was no longer a trivial file operation that just called down to the underlying file operations, but instead did at least two indirect calls. Indirect calls are sadly slow now with the Spectre mitigation, but the performance problem could at least be largely mitigated by changing the "->get_poll_head()" operation to just have a per-file-descriptor pointer to the poll head instead. That gets rid of one of the new indirections. But that doesn't fix the new complexity that is completely unwarranted for the regular case. The (undocumented) reason for the poll() changes was some alleged AIO poll race fixing, but we don't make the common case slower and more complex for some uncommon special case, so this all really needs way more explanations and most likely a fundamental redesign.

git://git.kernel.org/pub/scm/linux/kernel/git/palmer/riscv-linux Pull RISC-V updates from Palmer Dabbelt: "This contains some small RISC-V updates I'd like to target for 4.18. They are all fairly small this time. Here's a short summary, there's more info in the commits/merges: - a fix to __clear_user to respect the passed arguments. - enough support for the perf subsystem to work with RISC-V's ISA defined performance counters. - support for sparse and cleanups suggested by it. - support for R_RISCV_32 (a relocation, not the 32-bit ISA). - some MAINTAINERS cleanups. - the addition of CONFIG_HVC_RISCV_SBI to our defconfig, as it's always present. I've given these a simple build+boot test" * tag 'riscv-for-linus-4.18-merge_window' of git://git.kernel.org/pub/scm/linux/kernel/git/palmer/riscv-linux: RISC-V: Add CONFIG_HVC_RISCV_SBI=y to defconfig RISC-V: Handle R_RISCV_32 in modules riscv/ftrace: Export _mcount when DYNAMIC_FTRACE isn't set riscv: add riscv-specific predefines to CHECKFLAGS riscv: split the declaration of __copy_user riscv: no __user for probe_kernel_address() riscv: use NULL instead of a plain 0 perf: riscv: Add Document for Future Porting Guide perf: riscv: preliminary RISC-V support MAINTAINERS: Update Albert's email, he's back at Berkeley MAINTAINERS: Add myself as a maintainer for SiFive's drivers riscv: Fix the bug in memory access fixup code

2018-06-15docs: can.rst: fix a footnote referenceMauro Carvalho Chehab1-2/+2
As stated at: http://www.sphinx-doc.org/en/master/usage/restructuredtext/basics.html#footnotes A footnote should contain either a number, a reference or an auto number, e. g.: [1], [#f1] or [#]. While using [*] accidentaly works for html, it fails for other document outputs. In particular, it causes an error with LaTeX output, causing all books after networking to not be built. So, replace it by a valid syntax. Acked-by: Oliver Hartkopp <socketcan@hartkopp.net> Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org> Acked-by: Jonathan Corbet <corbet@lwn.net>
