* clk: ingenic: support PLLs with no bypass bitPaul Cercueil2018-01-18
| | | | | | | | | | | | | | The second PLL of the JZ4770 does not have a bypass bit. This commit makes it possible to support it with the current common CGU code.

* clk: ingenic: Fix recalc_rate for clocks with fixed dividerPaul Cercueil2018-01-18
| | | | | | | | | | | | | | | | | Previously, the clocks with a fixed divider would report their rate as being the same as the one of their parent, independently of the divider in use. This commit fixes this behaviour. This went unnoticed as neither the jz4740 nor the jz4780 CGU code have clocks with fixed dividers yet.

* MIPS: mipsregs.h: Make read_c0_prid use const accessorJames Hogan2018-01-09
| | | | | | | | | | | | | | | | | | | | Make read_c0_prid() use the new constant accessor macros so that it can potentially be optimised or removed by the compiler. This is particularly important under virtualisation, where even with hardware assisted virtualisation (VZ), access to the PRid register may need to be emulated by the hypervisor. In particular this helps eliminate the read of the PRid register in the rather frequently called add_interrupt_randomness() (which calls into arch/mips/include/asm/timex.h) when the prid is unused but the read can't be removed due to the inline asm being marked __volatile__.

* MIPS: mipsregs.h: Add read const Cop0 macrosJames Hogan2018-01-09
| | | | | | | | | | | | | | | | | | | | Some Cop0 registers are constant and have no side effects when read. There is no need for the inline asm to read these to be marked __volatile__, and doing so prevents them from being removed by the compiler. Add a few new accessor macros to handle these registers more efficiently (especially for the sake of running in a guest where redundant access to the register may trap to the hypervisor): __read_const_32bit_c0_register() __read_const_64bit_c0_register() __read_const_ulong_c0_register() Signed-off-by: James Hogan <jhogan@kernel.org> Cc: Ralf Baechle <ralf@linux-mips.org> Cc: Maciej W.

* MIPS: math-emu: Mark fall throughs in switch statements with a commentAleksandar Markovic2017-12-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Mark intentional fall throughs in switch statements with a consistent comment. In most of the cases, a new comment line containing text "fall through" is inserted. In some of the cases, existing comment contained a variation of the text "fall through" (for example, "FALL THROUGH" or "drop through"). In such cases, the existing comment is modified to contain "fall through". Lastly, in two cases, code segments were described in comments as "fall througs", but were in reality "breaks out" of switch statement. In such cases, existing comments are accordingly modified. Apart from making code easier to follow and debug, this change enables some static code analysers to interpret newly inserted comments as their annotations (and, therefore, not issue warnings of type "fall through in switch statement", which is desireable, since marked fallthroughs are intentional).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The name char array passed to btrfs_search_path_in_tree is of size BTRFS_INO_LOOKUP_PATH_MAX (4080). So the actual accessible char indexes are in the range of [0, 4079]. Currently the code uses the define but this represents an off-by-one. Implications: Size of btrfs_ioctl_ino_lookup_args is 4096, so the new byte will be written to extra space, not some padding that could be provided by the allocator. btrfs-progs store the arguments on stack, but kernel does own copy of the ioctl buffer and the off-by-one overwrite does not affect userspace, but the ending 0 might be lost. Kernel ioctl buffer is allocated dynamically so we're overwriting somebody else's memory, and the ioctl is privileged if args.objectid is not 256. Which is in most cases, but resolving a subvolume stored in another directory will trigger that path. Before this patch the buffer was one byte larger, but then the -1 was not added.

If we have quotas enabled, the data space reservation also includes a quota reservation. But in the rewrite case, the space has already been accounted for in qgroups. So btrfs_check_data_free_space() increases the quota reservation, but it never gets decreased when the data actually gets written and overwrites the pre-existing data. So we're left with both the qgroup and qgroup reservation accounting for the same space. This commit adds the missing btrfs_qgroup_free_data() call in the case of BTRFS_ORDERED_PREALLOC extents.

The GPIO interrupt controller however specifies the register offset without subtracting the "cbus" base address. This leads to a problem where of_iomap inside the irq-meson-gpio driver fails because it actually tries to map 0x182209880 (cbus base = 0xc1100000 + 0xc1109880 for the GPIO interrupt controller). Fix this by using 0x9880 as register offset.

Untested changes caused regressions in SCPI and CPUfreq/DVFS failures on most Amlogic SoCs. Changes reverted for v4.15 so they can be better reviewed and tested. These ARM SCPI changes caused SCPI regressions resulting in CPUfreq failures on most Amlogic SoCs (found by kernelci.org.) Unfortunately, this was not caught in linux-next due to other bugs/panics on these platforms masking this problem so we've only found it since we've fixed the other issues. Since we're already in the -rc cycle, I'd prefer to revert to a known working state (that of v4.14) rather than finding/reverting a subset, which would just lead to another untested state. These changes can then have some time to be better reviewed and tested and resubmitted for v4.16. Kevin Hilman has tested this revert on the affected Amlogic SoCs and verified that we're back to the previous (working) condition. This reverts commit 6710acf2596a29f7351e8165d981645f403e0025, reversing changes made to 4b367f2e8854da34d14bd154ff4432fb49f69b36.
