Linus Torvalds d129377639 ARM64: ... * Fix the guest view of the ID registers, making the relevant fields writable from userspace (affecting ID_AA64DFR0_EL1 and ID_AA64PFR1_EL1) * Correcly expose S1PIE to guests, fixing a regression introduced in 6.12-rc1 with the S1POE support * Fix the recycling of stage-2 shadow MMUs by tracking the context (are we allowed to block or not) as well as the recycling state * Address a couple of issues with the vgic when userspace misconfigures the emulation, resulting in various splats. Headaches courtesy of our Syzkaller friends * Stop wasting space in the HYP idmap, as we are dangerously close to the 4kB limit, and this has already exploded in -next * Fix another race in vgic_init() * Fix a UBSAN error when faking the cache topology with MTE enabled RISCV: * RISCV: KVM: use raw_spinlock for critical section in imsic x86: * A bandaid for lack of XCR0 setup in selftests, which causes trouble if the compiler is configured to have x86-64-v3 (with AVX) as the default ISA. Proper XCR0 setup will come in the next merge window. * Fix an issue where KVM would not ignore low bits of the nested CR3 and potentially leak up to 31 bytes out of the guest memory's bounds * Fix case in which an out-of-date cached value for the segments could by returned by KVM_GET_SREGS. * More cleanups for KVM_X86_QUIRK_SLOT_ZAP_ALL * Override MTRR state for KVM confidential guests, making it WB by default as is already the case for Hyper-V guests. Generic: * Remove a couple of unused functions -----BEGIN PGP SIGNATURE----- iQFIBAABCAAyFiEE8TM4V0tmI4mGbHaCv/vSX3jHroMFAmcVK54UHHBib256aW5p QHJlZGhhdC5jb20ACgkQv/vSX3jHroOfrgf7BRyihd28OGaqVuv2BqGYrxqfOkd6 ZqpJDOy+X7UE3iG5NhTxw4mghCJFhOwIL7gDSZwPLe6D2k01oqPSP2pLMqXb5oOv /EkltRvzG0YIH3sjZY5PROrMMxnvSKkJKxETFxFQQzMKRym2v/T5LAzrium58YIT vWZXxo2HTPXOw/U5upAqqMYJMeeJEL3kurVHtOsPytUFjrIOl0BfeKvgjOwonDIh Awm4JZwk0+1d8sYfkuzsSrTQmtshDCx1jkFN1juirt90s1EwgmOvVKiHo3gMsVP9 veDRoLTx2fM/r7TrhoHo46DTA2vbfmCltWcT0cn5x8P24BFGXXe/IDJIHA== =IVlI -----END PGP SIGNATURE----- Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm Pull kvm fixes from Paolo Bonzini: "ARM64: - Fix the guest view of the ID registers, making the relevant fields writable from userspace (affecting ID_AA64DFR0_EL1 and ID_AA64PFR1_EL1) - Correcly expose S1PIE to guests, fixing a regression introduced in 6.12-rc1 with the S1POE support - Fix the recycling of stage-2 shadow MMUs by tracking the context (are we allowed to block or not) as well as the recycling state - Address a couple of issues with the vgic when userspace misconfigures the emulation, resulting in various splats.
