2022-11-28ARM: 9268/1: vfp: Add hwcap FPHP and ASIMDHP for FEAT_FP16Amit Daniel Kachhap
Floating point half-precision (FPHP) and Advanced SIMD half-precision (ASIMDHP) are VFP features (FEAT_FP16) represented by MVFR1 identification register. These capabilities can optionally exist with VFPv3 and mandatory with VFPv4. Both these new features exist for Armv8 architecture in AArch32 state. These hwcaps may be useful for the userspace to add conditional check before trying to use FEAT_FP16 feature specific instructions.

2022-11-28ARM: 9267/1: Define Armv8 registers in AArch32 stateAmit Daniel Kachhap
AArch32 Instruction Set Attribute Register 6 (ID_ISAR6_EL1) and AArch32 Processor Feature Register 2 (ID_PFR2_EL1) identifies some new features for the Armv8 architecture. This registers will be utilized to add hwcaps for those cpu features. These registers are marked as reserved for Armv7 and should be a RAZ.

2022-11-28arm64: dts: apple: Add t600x L1/L2 cache properties and nodesRob Herring
The t600x CPU nodes are missing the cache hierarchy information. The cache hierarchy on Arm can not be detected and needs to be described in DT. The OS scheduler can make use of this information for scheduling decisions. The cache size information is based on various articles about the processors. There's also an L3 system level cache (SLC). It's not described here because SLCs typically have some MMIO interface which would need to be described. Signed-off-by: Rob Herring <robh@kernel.org> Signed-off-by: Hector Martin <marcan@marcan.st>

2022-11-25arm64/kpti: Move DAIF masking to C codeMark Brown
We really don't want to take an exception while replacing TTBR1 so we mask DAIF during the actual update. Currently this is done in the assembly function idmap_cpu_replace_ttbr1() but it could equally be done in the only caller of that function, cpu_replace_ttbr1(). This simplifies the assembly code slightly and means that when working with the code around masking DAIF flags there is one less piece of assembly code which needs to be considered. While we're at it add a comment which makes explicit why we are masking DAIF in this code. There should be no functional effect.

2022-11-25ftrace: arm64: remove static ftraceMark Rutland
The build test robot pointer out that there's a build failure when: CONFIG_HAVE_DYNAMIC_FTRACE_WITH_ARGS=y CONFIG_DYNAMIC_FTRACE_WITH_ARGS=n ... due to some mismatched ifdeffery, some of which checks CONFIG_HAVE_DYNAMIC_FTRACE_WITH_ARGS, and some of which checks CONFIG_DYNAMIC_FTRACE_WITH_ARGS, leading to some missing definitions expected by the core code when CONFIG_DYNAMIC_FTRACE=n and consequently CONFIG_DYNAMIC_FTRACE_WITH_ARGS=n. There's really not much point in supporting CONFIG_DYNAMIC_FTRACE=n (AKA static ftrace). All supported toolchains allow us to implement DYNAMIC_FTRACE, distributions all prefer DYNAMIC_FTRACE, and both powerpc and s390 removed support for static ftrace in commits: 0c0c52306f4792a4 ("powerpc: Only support DYNAMIC_FTRACE not static") 5d6a0163494c78ad ("s390/ftrace: enforce DYNAMIC_FTRACE if FUNCTION_TRACER is selected") ... and according to Steven, static ftrace is only supported on x86 to allow testing that the core code still functions in this configuration. Given that, let's simplify matters by removing arm64's support for static ftrace. This avoids the problem originally reported, and leaves us with less code to maintain.

2022-11-25x86/boot: Skip realmode init code when running as Xen PV guestJuergen Gross
When running as a Xen PV guest there is no need for setting up the realmode trampoline, as realmode isn't supported in this environment. Trying to setup the trampoline has been proven to be problematic in some cases, especially when trying to debug early boot problems with Xen requiring to keep the EFI boot-services memory mapped (some firmware variants seem to claim basically all memory below 1Mb for boot services). Introduce new x86_platform_ops operations for that purpose, which can be set to a NOP by the Xen PV specific kernel boot code.
