git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk fixes from Stephen Boyd: "A set of clk driver fixes that resolve issues for various SoCs. Most of these are incorrect clk data, like bad parent descriptions. When the clk tree is improperly described things don't work, like USB and UFS controllers, because clk frequencies are wonky. Here are the extra details: - Fix the parent of UFS reference clks on Qualcomm SC8280XP so that UFS works properly - Fix the clk ID for USB on AT91 RM9200 so the USB driver continues to probe - Stop using of_device_get_match_data() on the wrong device for a Samsung Exynos driver so it gets the proper clk data - Fix ExynosAutov9 binding - Fix the parent of the div4 clk on Exynos7885 - Stop calling runtime PM APIs from the Qualcomm GDSC driver directly as it leads to a lockdep splat and is just plain wrong because it violates runtime PM semantics by calling runtime PM APIs when the device has been runtime PM disabled" * tag 'clk-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: clk: qcom: gcc-sc8280xp: add cxo as parent for three ufs ref clks ARM: at91: rm9200: fix usb device clock id clk: samsung: Revert "clk: samsung: exynos-clkout: Use of_device_get_match_data()" dt-bindings: clock: exynosautov9: fix reference to CMU_FSYS1 clk: qcom: gdsc: Remove direct runtime PM calls clk: samsung: exynos7885: Correct "div4" clock parents

2022-11-15ARM: dts: rockchip: disable arm_global_timer on rk3066 and rk3188Johan Jonker2-1/+7
The clock source and the sched_clock provided by the arm_global_timer on Rockchip rk3066a/rk3188 are quite unstable because their rates depend on the CPU frequency. Recent changes to the arm_global_timer driver makes it impossible to use. On the other side, the arm_global_timer has a higher rating than the ROCKCHIP_TIMER, it will be selected by default by the time framework while we want to use the stable Rockchip clock source. Keep the arm_global_timer disabled in order to have the DW_APB_TIMER (rk3066a) or ROCKCHIP_TIMER (rk3188) selected by default.

2022-11-07ARM: 9266/1: mm: fix no-MMU ZERO_PAGE() implementationGiulio Benetti3-13/+28
Actually in no-MMU SoCs(i.e. i.MXRT) ZERO_PAGE(vaddr) expands to ``` virt_to_page(0) ``` that in order expands to: ``` pfn_to_page(virt_to_pfn(0)) ``` and then virt_to_pfn(0) to: ``` ((((unsigned long)(0) - PAGE_OFFSET) >> PAGE_SHIFT) + PHYS_PFN_OFFSET) ``` where PAGE_OFFSET and PHYS_PFN_OFFSET are the DRAM offset(0x80000000) and PAGE_SHIFT is 12. This way we obtain 16MB(0x01000000) summed to the base of DRAM(0x80000000). When ZERO_PAGE(0) is then used, for example in bio_add_page(), the page gets an address that is out of DRAM bounds. So instead of using fake virtual page 0 let's allocate a dedicated zero_page during paging_init() and assign it to a global 'struct page * empty_zero_page' the same way mmu.c does and it's the same approach used in m68k with commit dc068f462179 as discussed here[0]. Then let's move ZERO_PAGE() definition to the top of pgtable.h to be in common between mmu.c and nommu.c.

git://git.kernel.org/pub/scm/linux/kernel/git/crng/random Pull more random number generator updates from Jason Donenfeld: "This time with some large scale treewide cleanups. The intent of this pull is to clean up the way callers fetch random integers. The current rules for doing this right are: - If you want a secure or an insecure random u64, use get_random_u64() - If you want a secure or an insecure random u32, use get_random_u32() The old function prandom_u32() has been deprecated for a while now and is just a wrapper around get_random_u32(). Same for get_random_int(). - If you want a secure or an insecure random u16, use get_random_u16() - If you want a secure or an insecure random u8, use get_random_u8() - If you want secure or insecure random bytes, use get_random_bytes(). The old function prandom_bytes() has been deprecated for a while now and has long been a wrapper around get_random_bytes() - If you want a non-uniform random u32, u16, or u8 bounded by a certain open interval maximum, use prandom_u32_max() I say "non-uniform", because it doesn't do any rejection sampling or divisions. Hence, it stays within the prandom_*() namespace, not the get_random_*() namespace. I'm currently investigating a "uniform" function for 6.2. We'll see what comes of that. By applying these rules uniformly, we get several benefits: - By using prandom_u32_max() with an upper-bound that the compiler can prove at compile-time is ≤65536 or ≤256, internally get_random_u16() or get_random_u8() is used, which wastes fewer batched random bytes, and hence has higher throughput. - By using prandom_u32_max() instead of %, when the upper-bound is not a constant, division is still avoided, because prandom_u32_max() uses a faster multiplication-based trick instead. - By using get_random_u16() or get_random_u8() in cases where the return value is intended to indeed be a u16 or a u8, we waste fewer batched random bytes, and hence have higher throughput. This series was originally done by hand while I was on an airplane without Internet. Later, Kees and I worked on retroactively figuring out what could be done with Coccinelle and what had to be done manually, and then we split things up based on that. So while this touches a lot of files, the actual amount of code that's hand fiddled is comfortably small" * tag 'random-6.1-rc1-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random: prandom: remove unused functions treewide: use get_random_bytes() when possible treewide: use get_random_u32() when possible treewide: use get_random_{u8,u16}() when possible, part 2 treewide: use get_random_{u8,u16}() when possible, part 1 treewide: use prandom_u32_max() when possible, part 2 treewide: use prandom_u32_max() when possible, part 1

Another driver for EFI changes this cycle and in the future is confidential compute. The LoongArch architecture does not use either struct bootparams or DT natively [yet], and so passing information between the EFI stub and the core kernel using either of those is undesirable. And in general, overloading DT has been a source of issues on arm64, so using DT for this on new architectures is a to avoid for the time being (even if we might converge on something DT based for non-x86 architectures in the future). For this reason, in addition to the patch that enables EFI boot for LoongArch, there are a number of refactoring patches applied on top of which separate the DT bits from the generic EFI stub bits. These changes are on a separate topich branch that has been shared with the LoongArch maintainers, who will include it in their pull request as well. This is not ideal, but the best way to manage the conflicts without stalling LoongArch for another cycle. Another development inspired by LoongArch is the newly added support for EFI based decompressors. Instead of adding yet another arch-specific incarnation of this pattern for LoongArch, we are introducing an EFI app based on the existing EFI libstub infrastructure that encapulates the decompression code we use on other architectures, but in a way that is fully generic. This has been developed and tested in collaboration with distro and systemd folks, who are eager to start using this for systemd-boot and also for arm64 secure boot on Fedora. Note that the EFI zimage files this introduces can also be decompressed by non-EFI bootloaders if needed, as the image header describes the location of the payload inside the image, and the type of compression that was used. (Note that Fedora's arm64 GRUB is buggy [0] so you'll need a recent version or switch to systemd-boot in order to use this.) Finally, we are adding TPM measurement of the kernel command line provided by EFI. There is an oversight in the TCG spec which results in a blind spot for command line arguments passed to loaded images, which means that either the loader or the stub needs to take the measurement. Given the combinatorial explosion I am anticipating when it comes to firmware/bootloader stacks and firmware based attestation protocols (SEV-SNP, TDX, DICE, DRTM), it is good to set a baseline now when it comes to EFI measured boot, which is that the kernel measures the initrd and command line. Intermediate loaders can measure additional assets if needed, but with the baseline in place, we can deploy measured boot in a meaningful way even if you boot into Linux straight from the EFI firmware. Summary: - implement EFI boot support for LoongArch - implement generic EFI compressed boot support for arm64, RISC-V and LoongArch, none of which implement a decompressor today - measure the kernel command line into the TPM if measured boot is in effect - refactor the EFI stub code in order to isolate DT dependencies for architectures other than x86 - avoid calling SetVirtualAddressMap() on arm64 if the configured size of the VA space guarantees that doing so is unnecessary - move some ARM specific code out of the generic EFI source files - unmap kernel code from the x86 mixed mode 1:1 page tables" * tag 'efi-next-for-v6.1' of git://git.kernel.org/pub/scm/linux/kernel/git/efi/efi: (24 commits) efi/arm64: libstub: avoid SetVirtualAddressMap() when possible efi: zboot: create MemoryMapped() device path for the parent if needed efi: libstub: fix up the last remaining open coded boot service call efi/arm: libstub: move ARM specific code out of generic routines efi/libstub: measure EFI LoadOptions efi/libstub: refactor the initrd measuring functions efi/loongarch: libstub: remove dependency on flattened DT efi: libstub: install boot-time memory map as config table efi: libstub: remove DT dependency from generic stub efi: libstub: unify initrd loading between architectures efi: libstub: remove pointless goto kludge efi: libstub: simplify efi_get_memory_map() and struct efi_boot_memmap efi: libstub: avoid efi_get_memory_map() for allocating the virt map efi: libstub: drop pointless get_memory_map() call efi: libstub: fix type confusion for load_options_size arm64: efi: enable generic EFI compressed boot loongarch: efi: enable generic EFI compressed boot riscv: efi: enable generic EFI compressed boot efi/libstub: implement generic EFI zboot efi/libstub: move efi_system_table global var into separate object ...
