Merge tag 'x86_urgent_for_v5.17_rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull x86 fixes from Borislav Petkov:

 - Free shmem backing storage for SGX enclave pages when those are
   swapped back into EPC memory

 - Prevent do_int3() from being kprobed, to avoid recursion

 - Remap setup_data and setup_indirect structures properly when
   accessing their members

 - Correct the alternatives patching order for modules too
