2022-07-15kexec: clean up arch_kexec_kernel_verify_sigCoiby Xu
Before commit 105e10e2cf1c ("kexec_file: drop weak attribute from functions"), there was already no arch-specific implementation of arch_kexec_kernel_verify_sig. With weak attribute dropped by that commit, arch_kexec_kernel_verify_sig is completely useless. So clean it up. Note later patches are dependent on this patch so it should be backported to the stable tree as well. Cc: stable@vger.kernel.org Suggested-by: Eric W.

2022-07-15kexec_file: drop weak attribute from functionsNaveen N. Rao
As requested (http://lkml.kernel.org/r/87ee0q7b92.fsf@email.froward.int.ebiederm.org), this series converts weak functions in kexec to use the #ifdef approach. Quoting the 3e35142ef99fe ("kexec_file: drop weak attribute from arch_kexec_apply_relocations[_add]") changelog: : Since commit d1bcae833b32f1 ("ELF: Don't generate unused section symbols") : [1], binutils (v2.36+) started dropping section symbols that it thought : were unused. This isn't an issue in general, but with kexec_file.c, gcc : is placing kexec_arch_apply_relocations[_add] into a separate : .text.unlikely section and the section symbol ".text.unlikely" is being : dropped. Due to this, recordmcount is unable to find a non-weak symbol in : .text.unlikely to generate a relocation record against. This patch (of 2); Drop __weak attribute from functions in kexec_file.c: - arch_kexec_kernel_image_probe() - arch_kimage_file_post_load_cleanup() - arch_kexec_kernel_image_load() - arch_kexec_locate_mem_hole() - arch_kexec_kernel_verify_sig() arch_kexec_kernel_image_load() calls into kexec_image_load_default(), so drop the static attribute for the latter. arch_kexec_kernel_verify_sig() is not overridden by any architecture, so drop the __weak attribute.

2022-07-15drivers/base: fix userspace break from using bin_attributes for cpumap and ↵Phil Auld
cpulist Using bin_attributes with a 0 size causes fstat and friends to return that 0 size. This breaks userspace code that retrieves the size before reading the file. Rather than reverting 75bd50fa841 ("drivers/base/node.c: use bin_attribute to break the size limitation of cpumap ABI") let's put in a size value at compile time. For cpulist the maximum size is on the order of NR_CPUS * (ceil(log10(NR_CPUS)) + 1)/2 which for 8192 is 20480 (8192 * 5)/2. In order to get near that you'd need a system with every other CPU on one node. For example: (0,2,4,8, ... ). To simplify the math and support larger NR_CPUS in the future we are using (NR_CPUS * 7)/2. We also set it to a min of PAGE_SIZE to retain the older behavior for smaller NR_CPUS. The cpumap file the size works out to be NR_CPUS/4 + NR_CPUS/32 - 1 (or NR_CPUS * 9/32 - 1) including the ","s. Add a set of macros for these values to cpumask.h so they can be used in multiple places. Apply these to the handful of such files in drivers/base/topology.c as well as node.c. As an example, on an 80 cpu 4-node system (NR_CPUS == 8192): before: -r--r--r--. 1 root root 0 Jul 12 14:08 system/node/node0/cpulist -r--r--r--. 1 root root 0 Jul 11 17:25 system/node/node0/cpumap after: -r--r--r--. 1 root root 28672 Jul 13 11:32 system/node/node0/cpulist -r--r--r--. 1 root root 4096 Jul 13 11:31 system/node/node0/cpumap CONFIG_NR_CPUS = 16384 -r--r--r--. 1 root root 57344 Jul 13 14:03 system/node/node0/cpulist -r--r--r--. 1 root root 4607 Jul 13 14:02 system/node/node0/cpumap The actual number of cpus doesn't matter for the reported size since they are based on NR_CPUS.

https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next ASoC: Updates for v5.20 This is a big release thus far and there will probably be more changes to come, it's a combination of a larger than usual crop of new drivers and some subsysetm wide cleanups from Charles rather than anything structural. The SOF and Intel DSP code both also continue to be very actively developed. - Restructing of the set_fmt() callbacks to be specified in terms of the device rather than with semantics depending on if the device is supposed to be a CODEC or SoC, making things clearer in situations like CODEC to CODEC links. - Clean up of the way we flag which DAI naming scheme we use to reflect the progress that's been made modernising things. - Merge of more of the Intel AVS driver stack, including some board integrations. - New version 4 mechanism for communication with SOF DSPs. - Suppoort for dynamically selecting the PLL to use at runtime on i.MX platforms. - Improvements for CODEC to CODEC support in the generic cards. - Support for AMD Jadeite and various machines, Intel MetorLake DSPs, Mediatek MT8186 DSPs and MT6366, nVidia Tegra MDDRC, OPE and PEQ, NXP TFA9890, Qualcomm SDM845, WCD9335 and WAS883x, and Texas Instruments TAS2780.

2022-07-15iommu/amd: Introduce function to check and enable SNPBrijesh Singh
To support SNP, IOMMU needs to be enabled, and prohibits IOMMU configurations where DTE[Mode]=0, which means it cannot be supported with IOMMU passthrough domain (a.k.a IOMMU_DOMAIN_IDENTITY), and when AMD IOMMU driver is configured to not use the IOMMU host (v1) page table. Otherwise, RMP table initialization could cause the system to crash. The request to enable SNP support in IOMMU must be done before PCI initialization state of the IOMMU driver because enabling SNP affects how IOMMU driver sets up IOMMU data structures (i.e. DTE). Unlike other IOMMU features, SNP feature does not have an enable bit in the IOMMU control register. Instead, the IOMMU driver introduces an amd_iommu_snp_en variable to track enabling state of SNP. Introduce amd_iommu_snp_enable() for other drivers to request enabling the SNP support in IOMMU, which checks all prerequisites and determines if the feature can be safely enabled. Please see the IOMMU spec section 2.12 for further details.

Both submit_bh() and ll_rw_block() accept a request operation type and request flags as their first two arguments. Micro-optimize these two functions by combining these first two arguments into a single argument. This patch does not change the behavior of any of the modified code.

2022-07-14treewide: Rename enum req_opf into enum req_opBart Van Assche
The type name enum req_opf is misleading since it suggests that values of this type include both an operation type and flags. Since values of this type represent an operation only, change the type name into enum req_op. Convert the enum req_op documentation into kernel-doc format. Move a few definitions such that the enum req_op documentation occurs just above the enum req_op definition. The name "req_opf" was introduced by commit ef295ecf090d ("block: better op and flags encoding").

Introduce a new SMC command INTEL_SIP_SMC_FUNCID_SERVICE_COMPLETED that polls if a previous asynchronous command was completed. This SMC command is used by the new FPGA Crypto Service (FCS). A basic example is that the FCS sends an AES data encryption call to the secure device manager(SDM) and waits for the completion of the operation by continuously polling the results with the new command.
