Linus Torvalds f3dd0c5337 bpf: add missing header file include ... Commit 74e19ef0ff ("uaccess: Add speculation barrier to copy_from_user()") built fine on x86-64 and arm64, and that's the extent of my local build testing. It turns out those got the <linux/nospec.h> include incidentally through other header files (<linux/kvm_host.h> in particular), but that was not true of other architectures, resulting in build errors kernel/bpf/core.c: In function ‘___bpf_prog_run’: kernel/bpf/core.c:1913:3: error: implicit declaration of function ‘barrier_nospec’ so just make sure to explicitly include the proper <linux/nospec.h> header file to make everybody see it.
