Pull kvm fixes from Paolo Bonzini: "Two serious ARM fixes: - Plug a buffer overflow due to the use of the user-provided register width for firmware regs.

KVM/arm64 fixes for 6.3, part #4 - Plug a buffer overflow due to the use of the user-provided register width for firmware regs. Outright reject accesses where the user register width does not match the kernel representation. - Protect non-atomic RMW operations on vCPU flags against preemption, as an update to the flags by an intervening preemption could be lost.

KVM: arm64: Fix buffer overflow in kvm_arm_set_fw_reg()

2023-04-19T15:22:37Z

The KVM_REG_SIZE() comes from the ioctl and it can be a power of two between 0-32768 but if it is more than sizeof(long) this will corrupt memory.

LoongArch: Replace hard-coded values in comments with VALEN

2023-04-19T04:07:27Z

According to LoongArch documentation [1], CSR.PGDL and CSR.PGDH are concerned with the VA's MSB which is VALEN-1 instead of always being 47. Fix comments to avoid misleading others.
