Pull SPDX fixes from Greg KH: "Here are just two small patches, that fix up some found SPDX identifier issues. The first patch fixes an error in a previous SPDX fixup patch, that causes build errors when doing 'make clean' on the tree (the fact that almost no one noticed it reflects the fact that kernel developers don't like doing that option very often...) The second patch fixes up a number of places in the tree where people mistyped the string "SPDX-License-Identifier". Given that people can not even type their own name all the time without mistakes, this was bound to happen, and odds are, we will have to add some type of check for this to checkpatch.pl to catch this happening in the future.

When we have holes in a normal memory zone, we could endup having cached_migrate_pfns which may not necessarily be valid, under heavy memory pressure with swapping enabled ( via __reset_isolation_suitable(), triggered by kswapd). Later if we fail to find a page via fast_isolate_freepages(), we may end up using the migrate_pfn we started the search with, as valid page. This could lead to accessing NULL pointer derefernces like below, due to an invalid mem_section pointer.

In the fixes commit, removing SIGKILL from each thread signal mask and executing "goto fatal" directly will skip the call to "trace_signal_deliver". At this point, the delivery tracking of the SIGKILL signal will be inaccurate. Therefore, we need to add trace_signal_deliver before "goto fatal" after executing sigdelset. Note: SEND_SIG_NOINFO matches the fact that SIGKILL doesn't have any info.

When get_user_pages*() is called with pages = NULL, the processing of VM_FAULT_RETRY terminates early without actually retrying to fault-in all the pages. If the pages in the requested range belong to a VMA that has userfaultfd registered, handle_userfault() returns VM_FAULT_RETRY *after* user space has populated the page, but for the gup pre-fault case there's no actual retry and the caller will get no pages although they are present. This issue was uncovered when running post-copy memory restore in CRIU after d9c9ce34 ("x86/fpu: Fault-in user stack if copy_fpstate_to_sigframe() fails"). After this change, the copying of FPU state to the sigframe switched from copy_to_user() variants which caused a real page fault to get_user_pages() with pages parameter set to NULL. In post-copy mode of CRIU, the destination memory is managed with userfaultfd and lack of the retry for pre-fault case in get_user_pages() causes a crash of the restored process. Making the pre-fault behavior of get_user_pages() the same as the "normal" one fixes the issue.
