Commit 5658e8cf ("clk: qcom: add video clock controller driver for SM8150") and commit 0e94711a ("clk: qcom: add video clock controller driver for SM8250") add config SM_VIDEOCC_8150 and config SM_VIDEOCC_8250, which select the non-existing configs SDM_GCC_8150 and SDM_GCC_8250, respectively. Hence, ./scripts/checkkconfigsymbols.py warns: SDM_GCC_8150 Referencing files: drivers/clk/qcom/Kconfig SDM_GCC_8250 Referencing files: drivers/clk/qcom/Kconfig It is probably just a typo (or naming confusion of using SM_GCC_xxx and SDM_GCC_xxx for various Qualcomm clock drivers) in the config definitions for config SM_VIDEOCC_8150 and SM_VIDEOCC_8250, and intends to select the existing SM_GCC_8150 and SM_GCC_8250, respectively. Adjust the selects to the existing configs. Signed-off-by:

Using parent_data and parent_hws, instead of parent_names, does protect against some cases of incompletely defined clock trees. While it turns out that the bug being chased this time was totally unrelated, this patch converts the SDM660 GCC driver to avoid such issues. The "xo" fixed_factor clock is unused within the gcc driver, but referenced from the DSI PHY. So it's left in place until the DSI driver is updated. Tested-by:

A typical code pattern for pm_clk_create() call is to call it in the _probe function and to call pm_clk_destroy() both from _probe error path and from _remove function. For some drivers the whole remove function would consist of the call to pm_remove_disable(). Add helper function to replace this bolierplate piece of code. Calling devm_pm_clk_create() removes the need for calling pm_clk_destroy() both in the probe()'s error path and in the remove() function. Signed-off-by:

MSM8939 has 3 a53pll clocks with different frequency table for Cluster0, Cluster1 and CCI. It adds function qcom_a53pll_get_freq_tbl() to create pll_freq_tbl from OPP, so that those a53pll frequencies can be defined in DT with operating-points-v2 bindings rather than being coded in the driver. In this case, one compatible rather than three would be needed for these 3 a53pll clocks. Signed-off-by:

Different from MSM8916 which has only one a53pll/mux clock, MSM8939 gets three for Cluster0 (little cores), Cluster1 (big cores) and CCI (Cache Coherent Interconnect). That said, a53pll/mux clock needs to be named uniquely. Append @unit-address of device node to the clock name, so that a53pll/mux will be named like below on MSM8939. a53pll@b016000 a53pll@b116000 a53pll@b1d0000 a53mux@b1d1000 a53mux@b011000 a53mux@b111000 Signed-off-by:

The clock source for MSM8916 cpu cores is like below. |\ a53pll --------| \ a53mux +------+ | |------------| cpus | gpll0_vote --------| / +------+ |/ So a53mux rather than a53pll is actually the parent clock of cpu cores. It makes more sense to flag a53mux as critical instead, so that when either a53pll or gpll0_vote is used by cpu cores, the clock will be kept enabled while the other can be disabled. Signed-off-by: -

The kernel recovers in due course from missing Mlocked pages: but there was no point in calling page_mlock() (formerly known as try_to_munlock()) on a THP, because nothing got done even when it was found to be mapped in another VM_LOCKED vma. It's true that we need to be careful: Mlocked accounting of pte-mapped THPs is too difficult (so consistently avoided); but Mlocked accounting of only-pmd-mapped THPs is supposed to work, even when multiple mappings are mlocked and munlocked or munmapped. Refine the tests. There is already a VM_BUG_ON_PAGE(PageDoubleMap) in page_mlock(), so page_mlock_one() does not even have to worry about that complication. (I said the kernel recovers: but would page reclaim be likely to split THP before rediscovering that it's VM_LOCKED? I've not followed that up) Fixes: 9a73f61b ("thp, mlock: do not mlock PTE-mapped file huge pages") Signed-off-by:

Parallel developments in mm/rmap.c have left behind some out-of-date comments: try_to_migrate_one() also accepts TTU_SYNC (already commented in try_to_migrate() itself), and try_to_migrate() returns nothing at all. TTU_SPLIT_FREEZE has just been deleted, so reword the comment about it in mm/huge_memory.c; and TTU_IGNORE_ACCESS was removed in 5.11, so delete the "recently referenced" comment from try_to_unmap_one() (once upon a time the comment was near the removed codeblock, but they drifted apart).
