kmap() is being deprecated in favor of kmap_local_page(). There are two main problems with kmap(): (1) It comes with an overhead as the mapping space is restricted and protected by a global lock for synchronization and (2) it also requires global TLB invalidation when the kmap’s pool wraps and it might block when the mapping space is fully utilized until a slot becomes available. With kmap_local_page() the mappings are per thread, CPU local, can take page faults, and can be called from any context (including interrupts). It is faster than kmap() in kernels with HIGHMEM enabled. Furthermore, the tasks can be preempted and, when they are scheduled to run again, the kernel virtual addresses are restored and still valid. Since its use in xilinx_sdfec.c is safe, replace kmap()i / kunmap() with kmap_local_page() / kunmap_local(). Cc: "Venkataramanan, Anirudh" <anirudh.venkataramanan@intel.com> Suggested-by:

-Wformat was recently re-enabled for builds with clang, then quickly re-disabled, due to concerns stemming from the frequency of default argument promotion related warning instances. commit 258fafcd ("Makefile.extrawarn: re-enable -Wformat for clang") commit 21f9c8a1 ("Revert "Makefile.extrawarn: re-enable -Wformat for clang"") ISO WG14 has ratified N2562 to address default argument promotion explicitly for printf, as part of the upcoming ISO C2X standard. The behavior of clang was changed in clang-16 to not warn for the cited cases in all language modes. Add a version check, so that users of clang-16 now get the full effect of -Wformat. For older clang versions, re-enable flags under the -Wformat group that way users still get some useful checks related to format strings, without noisy default argument promotion warnings. I intentionally omitted -Wformat-y2k and -Wformat-security from being re-enabled, which are also part of -Wformat in clang-16.

Pull clk fixes from Stephen Boyd: "Here's a collection of primarily clk driver fixes, with a couple fixes to the core framework. We had to revert out a commit that affected boot on some devices that have the CLK_OPS_PARENT_ENABLE flag set. It isn't critical to have that fix so we'll try again next time. Driver side fixes include: - Plug an OF-node refcount bug in the TI clk driver - Fix the error handling in the raspberry pi firmware get_rate so that errors don't look like valid frequencies - Avoid going out of bounds in the raspberry pi driver too if the video firmware returns something we're not expecting" * tag 'clk-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: Revert "clk: core: Honor CLK_OPS_PARENT_ENABLE for clk gate ops" clk: bcm: rpi: Show clock id limit in error case clk: bcm: rpi: Add missing newline clk: bcm: rpi: Prevent out-of-bounds access clk: bcm: rpi: Fix error handling of raspberrypi_fw_get_rate clk: core: Fix runtime PM sequence in clk_core_unprepare() clk: core: Honor CLK_OPS_PARENT_ENABLE for clk gate ops clk: ti: Fix missing of_node_get() ti_find_clock_provider() -

The mmap lock protects the page walker from changes to the page tables during the walk. However a read lock is insufficient to protect those areas which don't have a VMA as munmap() detaches the VMAs before downgrading to a read lock and actually tearing down PTEs/page tables. For users of walk_page_range() the solution is to simply call pte_hole() immediately without checking the actual page tables when a VMA is not present. We now never call __walk_page_range() without a valid vma. For walk_page_range_novma() the locking requirements are tightened to require the mmap write lock to be taken, and then walking the pgd directly with 'no_vma' set. This in turn means that all page walkers either have a valid vma, or it's that special 'novma' case for page table debugging. As a result, all the odd '(!walk->vma && !walk->no_vma)' tests can be removed. Fixes: dd2283f2 ("mm: mmap: zap pages with read mmap_sem in munmap") Reported-by:
