Pull x86 fixes from Ingo Molnar: "Fix preemption delays in the SGX code, remove unnecessarily UAPI-exported code, fix a ld.lld linker (in)compatibility quirk and make the x86 SMP init code a bit more conservative to fix kexec() lockups" * tag 'x86-urgent-2023-09-10' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/sgx: Break up long non-preemptible delays in sgx_vepc_release() x86: Remove the arch_calc_vm_prot_bits() macro from the UAPI x86/build: Fix linker fill bytes quirk/incompatibility for ld.lld x86/smp: Don't send INIT to non-present and non-booted CPUs
