ocfs2: fix crash in ocfs2_duplicate_clusters_by_page()

ocfs2_duplicate_clusters_by_page() may crash if one of the extent's pages
is dirty. When a page has not been written back, it is still in dirt

ocfs2: fix crash in ocfs2_duplicate_clusters_by_page()

ocfs2_duplicate_clusters_by_page() may crash if one of the extent's pages
is dirty. When a page has not been written back, it is still in dirty
state. If ocfs2_duplicate_clusters_by_page() is called against the dirty
page, the crash happens.

To fix this bug, we can just unlock the page and wait until the page until
its not dirty.

The following is the backtrace:

kernel BUG at /root/code/ocfs2/refcounttree.c:2961!
[exception RIP: ocfs2_duplicate_clusters_by_page+822]
__ocfs2_move_extent+0x80/0x450 [ocfs2]

do_syscall_64+0x74/0x140

Once we find the page is dirty, we do not wait until it's clean, rather we
use write_one_page() to write it back

S390 bpf_jit.S is removed in net-next and had changes in 'net',
since that code isn't used any more take the removal.

TLS data structures split the TX and RX components in 'net-next',
put the new struct members from the bug fix in 'net' into the RX
part.

The 'net-next' tree had some reworking of how the ERSPAN code works in
the GRE tunneling code, overlapping with a one-line headroom
calculation fix in 'net'.

Overlapping changes in __sock_map_ctx_update_elem(), keep the bits
that read the prog members via READ_ONCE() into local variables
before using them.
