git://git.linaro.org/people/mike.turquette/linux Pull clock framework updates from Mike Turquette: "The clock framework changes contain the usual driver additions, enhancements and fixes mostly for ARM32, ARM64, MIPS and Power-based devices. Additionally the framework core underwent a bit of surgery with two major changes: - The boundary between the clock core and clock providers (e.g clock drivers) is now more well defined with dedicated provider helper functions. struct clk no longer maps 1:1 with the hardware clock but is a true per-user cookie which helps us tracker users of hardware clocks and debug bad behavior. - The addition of rate constraints for clocks. Rate ranges are now supported which are analogous to the voltage ranges in the regulator framework. Unfortunately these changes to the core created some breakeage. We think we fixed it all up but for this reason there are lots of last minute commits trying to undo the damage" * tag 'clk-for-linus-3.20' of git://git.linaro.org/people/mike.turquette/linux: (113 commits) clk: Only recalculate the rate if needed Revert "clk: mxs: Fix invalid 32-bit access to frac registers" clk: qoriq: Add support for the platform PLL powerpc/corenet: Enable CLK_QORIQ clk: Replace explicit clk assignment with __clk_hw_set_clk clk: Add __clk_hw_set_clk helper function clk: Don't dereference parent clock if is NULL MIPS: Alchemy: Remove bogus args from alchemy_clk_fgcs_detr clkdev: Always allocate a struct clk and call __clk_get() w/ CCF clk: shmobile: div6: Avoid division by zero in .round_rate() clk: mxs: Fix invalid 32-bit access to frac registers clk: omap: compile legacy omap3 clocks conditionally clkdev: Export clk_register_clkdev clk: Add rate constraints to clocks clk: remove clk-private.h pci: xgene: do not use clk-private.h arm: omap2+ remove dead clock code clk: Make clk API return per-user struct clk instances clk: tegra: Define PLLD_DSI and remove dsia(b)_mux clk: tegra: Add support for the Tegra132 CAR IP block ...

2015-02-21kernel: make READ_ONCE() valid on const argumentsLinus Torvalds1-3/+3
The use of READ_ONCE() causes lots of warnings witht he pending paravirt spinlock fixes, because those ends up having passing a member to a 'const' structure to READ_ONCE(). There should certainly be nothing wrong with using READ_ONCE() with a const source, but the helper function __read_once_size() would cause warnings because it would drop the 'const' qualifier, but also because the destination would be marked 'const' too due to the use of 'typeof'. Use a union of types in READ_ONCE() to avoid this issue. Also make sure to use parenthesis around the macro arguments to avoid possible operator precedence issues.

2015-02-21kprobes/x86: Check for invalid ftrace location in __recover_probed_insn()Petr Mladek2-0/+14
__recover_probed_insn() should always be called from an address where an instructions starts. The check for ftrace_location() might help to discover a potential inconsistency. This patch adds WARN_ON() when the inconsistency is detected. Also it adds handling of the situation when the original code can not get recovered.

2015-02-21kprobes/x86: Use 5-byte NOP when the code might be modified by ftracePetr Mladek1-14/+28
can_probe() checks if the given address points to the beginning of an instruction. It analyzes all the instructions from the beginning of the function until the given address. The code might be modified by another Kprobe. In this case, the current code is read into a buffer, int3 breakpoint is replaced by the saved opcode in the buffer, and can_probe() analyzes the buffer instead. There is a bug that __recover_probed_insn() tries to restore the original code even for Kprobes using the ftrace framework. But in this case, the opcode is not stored. See the difference between arch_prepare_kprobe() and arch_prepare_kprobe_ftrace(). The opcode is stored by arch_copy_kprobe() only from arch_prepare_kprobe(). This patch makes Kprobe to use the ideal 5-byte NOP when the code can be modified by ftrace. It is the original instruction, see ftrace_make_nop() and ftrace_nop_replace(). Note that we always need to use the NOP for ftrace locations. Kprobes do not block ftrace and the instruction might get modified at anytime. It might even be in an inconsistent state because it is modified step by step using the int3 breakpoint. The patch also fixes indentation of the touched comment. Note that I found this problem when playing with Kprobes. I did it on x86_64 with gcc-4.8.3 that supported -mfentry. I modified samples/kprobes/kprobe_example.c and added offset 5 to put the probe right after the fentry area: static struct kprobe kp = { .symbol_name = "do_fork", + .offset = 5, }; Then I was able to load kprobe_example before jprobe_example but not the other way around: $> modprobe jprobe_example $> modprobe kprobe_example modprobe: ERROR: could not insert 'kprobe_example': Invalid or incomplete multibyte or wide character It did not make much sense and debugging pointed to the bug described above.

2015-02-20blk-throttle: check stats_cpu before reading it from sysfsThadeu Lima de Souza Cascardo1-0/+3
When reading blkio.throttle.io_serviced in a recently created blkio cgroup, it's possible to race against the creation of a throttle policy, which delays the allocation of stats_cpu. Like other functions in the throttle code, just checking for a NULL stats_cpu prevents the following oops caused by that race.

In commit c441d4a54c6e ("MIPS: mm: Only build one microassembler that is suitable"), the Makefile at arch/mips/mm was rewritten to only build the "right" microassembler file, depending on whether CONFIG_CPU_MICROMIPS is set or not. In the files, however, there are still preprocessor definitions depending on CONFIG_CPU_MICROMIPS. The #ifdef around them can now never evaluate to true, so let's remove them altogether.

2015-02-20i2c: ocores: rework clk code to handle NULL cookieWolfram Sang1-14/+21
For, !HAVE_CLK the clk API returns a NULL cookie. Rework the initialization code to handle that. If clk_get_rate() delivers 0, we use the fallback mechanisms. The patch is pretty easy when ignoring white space issues (git diff -b).

2015-02-20Btrfs: fix allocation size calculations in alloc_btrfs_bioChris Mason1-1/+8
Since commit 8e5cfb55d3f (Btrfs: Make raid_map array be inlined in btrfs_bio structure), the raid map array is allocated along with the btrfs bio in alloc_btrfs_bio. The calculation used to decide how much we need to allocate was using the wrong parameter passed into the allocation function. The passed in real_stripes will be zero if a target replace operation is not currently running. We want to use total_stripes instead.

2015-02-20MIPS: Alchemy: Fix cpu clock calculationManuel Lauss1-0/+2
The current code uses bits 0-6 of the sys_cpupll register to calculate core clock speed. However this is only valid on Au1300, on all earlier models the hardware only uses bits 0-5 to generate core clock. This fixes clock calculation on the MTX1 (Au1500), where bit 6 of cpupll is set as well, which ultimately lead the code to calculate a bogus cpu core clock and also uart base clock down the line.
