Remove unnecessary variable mfn in function xen_foreach_remap_area() and,
refactor the code.
Variable mfn at line 518:mfn = xen_remap_buf.mfns[i];
is only being used to store a value to be passed as
an argument to the xen_update_mem_tables() function.
This value can be passed directly, which makes variable
mfn unnecessary. Also, value assigned to variable mfn
at line 534:mfn = xen_remap_mfn; is never used.

Misc BPF helper/verifier improvements
Miscellanous improvements I still had in my queue, it adds a new
bpf_skb_adjust_room() helper for cls_bpf, exports to fdinfo whether
tail call array owner is JITed, so iproute2 error reporting can be
improved on that regard, a small cleanup and extension to trace
printk, two verifier patches, one to make the code around narrower
ctx access a bit more straight forward and one to allow for imm += x
operations, that we've seen LLVM generating and the verifier currently
rejecting. We've included the patch 6 given it's rather small and
we ran into it from LLVM side, it would be great if it could be
queued for stable as well after the merge window. Last but not least,
test cases are added also related to imm alu improvement.
Thanks a lot!

Currently the verifier does not track imm across alu operations when
the source register is of unknown type. This adds additional pattern
matching to catch this and track imm. We've seen LLVM generating this
pattern while working on cilium.

Currently, bpf_trace_printk does not support common formatting
symbol '%i' however vsprintf does and is what eventually gets
called by bpf helper. If users are used to '%i' and currently
make use of it, then bpf_trace_printk will just return with
error without dumping anything to the trace pipe, so just add
support for '%i' to the helper.
