Merge branch 'x86-kdump-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x865 kdump updates from Thomas Gleixner: "Yet more kexec/kdump updates: - Properly support kexec when AMD's memory encryption (SME) is enabled - Pass reserved e820 ranges to the kexec kernel so both PCI and SME can work" * 'x86-kdump-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: fs/proc/vmcore: Enable dumping of encrypted memory when SEV was active x86/kexec: Set the C-bit in the identity map page table when SEV is active x86/kexec: Do not map kexec area as decrypted when SEV is active x86/crash: Add e820 reserved ranges to kdump kernel's e820 table x86/mm: Rework ioremap resource mapping determination x86/e820, ioport: Add a new I/O resource descriptor IORES_DESC_RESERVED x86/mm: Create a workarea in the kernel for SME early encryption x86/mm: Identify the end of the kernel area to be reserved
