Force the inlining with the kernel's own __inline_* versions (Mauricio Faria de Oliveira) - Cleanups and fixlets* tag 'x86_boot_for_v7.4_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/boot: Drop unused implementation of panic() x86/boot: Move unaccepted memory handling out of the decompressor x86/tdx: Share tdx_panic() with the EFI stub x86/pvh: Really inline memcmp() and memset() to fix unbootable VMs x86/asm: Group inline string functions x86/asm, x86/boot: Carve out inline memcmp() into a separate header x86/boot: Remove redundant "cc" clobber in memcmp() and document it x86/boot: Use BASE_BAUD and DEFAULT_SERIAL_PORT List of files: /linux/arch/x86/include/asm/shared/string.h

x86/asm, x86/boot: Carve out inline memcmp() into a separate headerMove the inline memcmp() function currently only available in boot/string.cinto the shared string function header to be reused.This is not done through to avoid pulling unnecessary codein boot/string.c that causes build errors in boot/compressed/string.cand purgatory/purgatory.ro.No functional changes.
