2023-10-11cpu-hotplug: Provide prototypes for arch CPU registrationRussell King (Oracle)
Provide common prototypes for arch_register_cpu() and arch_unregister_cpu(). These are called by acpi_processor.c, with weak versions, so the prototype for this is already set. It is generally not necessary for function prototypes to be conditional on preprocessor macros. Some architectures (e.g. Loongarch) are missing the prototype for this, and rather than add it to Loongarch's asm/cpu.h, do the job once for everyone. Since this covers everyone, remove the now unnecessary prototypes in asm/cpu.h, and therefore remove the 'static' from one of ia64's arch_register_cpu() definitions.

Since commit: 4d96f9109109b ("x86/sev: Replace occurrences of sev_active() with cc_platform_has()") ... the SWIOTLB bounce buffer size adjustment and restricted virtio memory setting also inadvertently apply to TDX: the code is using cc_platform_has(CC_ATTR_GUEST_MEM_ENCRYPT) as a gatekeeping condition, which is also true for TDX, and this is also what we want. To reflect this, move the corresponding code to generic mem_encrypt.c. No functional changes intended.

2023-10-10KVM: VMX: drop IPAT in memtype when CD=1 for KVM_X86_QUIRK_CD_NW_CLEAREDYan Zhao
For KVM_X86_QUIRK_CD_NW_CLEARED is on, remove the IPAT (ignore PAT) bit in EPT memory types when cache is disabled and non-coherent DMA are present. To correctly emulate CR0.CD=1, UC + IPAT are required as memtype in EPT. However, as with commit fb279950ba02 ("KVM: vmx: obey KVM_QUIRK_CD_NW_CLEARED"), WB + IPAT are now returned to workaround a BIOS issue that guest MTRRs are enabled too late. Without this workaround, a super slow guest boot-up is expected during the pre-guest-MTRR-enabled period due to UC as the effective memory type for all guest memory. Absent emulating CR0.CD=1 with UC, it makes no sense to set IPAT when KVM is honoring the guest memtype. Removing the IPAT bit in this patch allows effective memory type to honor PAT values as well, as WB is the weakest memtype. It means if a guest explicitly claims UC as the memtype in PAT, the effective memory is UC instead of previous WB. If, for some unknown reason, a guest meets a slow boot-up issue with the removal of IPAT, it's desired to fix the blamed PAT in the guest. Returning guest MTRR type as if CR0.CD=0 is also not preferred because KVMs ABI for the quirk also requires KVM to force WB memtype regardless of guest MTRRs to workaround the slow guest boot-up issue. In the future, honoring guest PAT will also allow KVM to more precisely zap SPTEs when the effective memtype changes. E.g. by not forcing WB when CR0.CD=1, instead of zapping SPTEs when guest MTRRs change, KVM can skip MTRR-induced zaps if CR0.CD=1 and zap SPTEs for non-WB MTRR ranges when CR0.CD is toggled (WB MTRR SPTEs can be kept because they're WB regardless of CR0.CD). The change of removing IPAT has been verified with normal boot-up time on old OVMF of commit c9e5618f84b0cb54a9ac2d7604f7b7e7859b45a7 as well, dated back to Apr 14 2015.

2023-10-10KVM: x86/mmu: Zap KVM TDP when noncoherent DMA assignment starts/stopsYan Zhao
Zap KVM TDP when noncoherent DMA assignment starts (noncoherent dma count transitions from 0 to 1) or stops (noncoherent dma count transitions from 1 to 0). Before the zap, test if guest MTRR is to be honored after the assignment starts or was honored before the assignment stops. When there's no noncoherent DMA device, EPT memory type is ((MTRR_TYPE_WRBACK << VMX_EPT_MT_EPTE_SHIFT) | VMX_EPT_IPAT_BIT) When there're noncoherent DMA devices, EPT memory type needs to honor guest CR0.CD and MTRR settings. So, if noncoherent DMA count transitions between 0 and 1, EPT leaf entries need to be zapped to clear stale memory type. This issue might be hidden when the device is statically assigned with VFIO adding/removing MMIO regions of the noncoherent DMA devices for several times during guest boot, and current KVM MMU will call kvm_mmu_zap_all_fast() on the memslot removal. But if the device is hot-plugged, or if the guest has mmio_always_on for the device, the MMIO regions of it may only be added for once, then there's no path to do the EPT entries zapping to clear stale memory type. Therefore do the EPT zapping when noncoherent assignment starts/stops to ensure stale entries cleaned away.

When the flush is needed the code jumps out-of-line to do the flush, and then intends to jump back to continue the syscall return. However the branch back to label 1b doesn't return to the correct location, instead branching back just prior to the return to userspace, causing bogus register values to be used by the rfi. The breakage was introduced by commit 6f76a01173cc ("powerpc/syscall: implement system call entry/exit logic in C for PPC32") which inadvertently removed the "1" label and reused it elsewhere. Fix it by adding named local labels in the correct locations. Note that the return label needs to be outside the ifdef so that CONFIG_PPC_47x=n compiles.

2023-10-11s390/bpf: Fix clobbering the caller's backchain in the trampolineIlya Leoshkevich
One of the first things that s390x kernel functions do is storing the the caller's frame address (backchain) on stack. This makes unwinding possible. The backchain is always stored at frame offset 152, which is inside the 160-byte stack area, that the functions allocate for their callees. The callees must preserve the backchain; the remaining 152 bytes they may use as they please. Currently the trampoline uses all 160 bytes, clobbering the backchain. This causes kernel panics when using __builtin_return_address() in functions called by the trampoline. Fix by reducing the usage of the caller-reserved stack area by 8 bytes in the trampoline.

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull irq fixes from Thomas Gleixner: "A set of updates for interrupt chip drivers: - Fix the fail of the Qualcomm PDC driver on v3.2 hardware which is caused by a control bit being moved to a different location - Update the SM8150 device tree PDC resource so the version register can be read - Make the Renesas RZG2L driver correct for interrupts which are outside of the LSB in the TSSR register by using the proper macro for calculating the mask - Document the Renesas RZ2GL device tree binding correctly and update them for a few devices which faul to boot otherwise - Use the proper accessor in the RZ2GL driver instead of blindly dereferencing an unchecked pointer - Make GICv3 handle the dma-non-coherent attribute correctly - Ensure that all interrupt controller nodes on RISCV are marked as initialized correctly Maintainer changes: - Add a new entry for GIC interrupt controllers and assign Marc Zyngier as the maintainer - Remove Marc Zyngier from the core and driver maintainer entries as he is burried in work and short of time to handle that. Thanks to Marc for all the great work he has done in the past couple of years! Also note that commit 5873d380f4c0 ("irqchip/qcom-pdc: Add support for v3.2 HW") has a incorrect SOB chain. The real author is Neil. His patch was posted by Dmitry once and Neil picked it up from the list and reposted it with the bogus SOB chain. Not a big deal, but worth to mention. I wanted to fix that up, but then got distracted and Marc piled more changes on top. So I decided to leave it as is instead of rebasing world" * tag 'irq-urgent-2023-10-10-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: MAINTAINERS: Remove myself from the general IRQ subsystem maintenance MAINTAINERS: Add myself as the ARM GIC maintainer irqchip/renesas-rzg2l: Convert to irq_data_get_irq_chip_data() irqchip/stm32-exti: add missing DT IRQ flag translation irqchip/riscv-intc: Mark all INTC nodes as initialized irqchip/gic-v3: Enable non-coherent redistributors/ITSes DT probing irqchip/gic-v3-its: Split allocation from initialisation of its_node dt-bindings: interrupt-controller: arm,gic-v3: Add dma-noncoherent property dt-bindings: interrupt-controller: renesas,irqc: Add r8a779f0 support dt-bindings: interrupt-controller: renesas,rzg2l-irqc: Document RZ/G2UL SoC irqchip: renesas-rzg2l: Fix logic to clear TINT interrupt source dt-bindings: interrupt-controller: renesas,rzg2l-irqc: Update description for '#interrupt-cells' property arm64: dts: qcom: sm8150: extend the size of the PDC resource irqchip/qcom-pdc: Add support for v3.2 HW

2023-10-10x86/cpu/topology: Cure the abuse of cpuinfo for persisting logical idsThomas Gleixner
Per CPU cpuinfo is used to persist the logical package and die IDs. That's really not the right place simply because cpuinfo is subject to be reinitialized when a CPU goes through an offline/online cycle. This works by chance today, but that's far from correct and neither obvious nor documented. Add a per cpu datastructure which persists those logical IDs, which allows to cleanup the CPUID evaluation code. This is a temporary workaround until the larger topology management is in place, which makes all of this logical management mechanics obsolete.
