In sysfs_rename we need to remove the optimization of not calling
sysfs_unlink_sibling and sysfs_link_sibling if the renamed parent
directory is not changing. This optimization is no longer valid now
that sysfs dirents are stored in an rbtree sorted by name.
Move the assignment of s_ns before the call of sysfs_link_sibling. With
no sysfs_dirent fields changing after the call of sysfs_link_sibling
this allows sysfs_link_sibling to take any of the directory entries into
account when it builds the rbtrees, and s_ns looks like a prime canidate
to be used in the rbtree in the future.

This is the fifth version of the patchset (with one tiny whitespace fix)
to the Linux kernel to support the Qualcomm Hexagon architecture.
Between now and the next pull requests, Richard Kuo should have his key
signed, etc., and should be back on kernel.org. In the meantime, this
got merged as a emailed patch-series.
* Hexagon: (36 commits)
Add extra arch overrides to asm-generic/checksum.h
Hexagon: Add self to MAINTAINERS
Hexagon: Add basic stacktrace functionality for Hexagon architecture.
Hexagon: Add configuration and makefiles for the Hexagon architecture.
Hexagon: Comet platform support
Hexagon: kgdb support files
Hexagon: Add page-fault support.
Hexagon: Add page table header files & etc.
Hexagon: Add ioremap support
Hexagon: Provide DMA implementation
Hexagon: Implement basic TLB management routines for Hexagon.
Hexagon: Implement basic cache-flush support
Hexagon: Provide basic implementation and/or stubs for I/O routines.
Hexagon: Add user access functions
Hexagon: Add locking types and functions
Hexagon: Add SMP support
Hexagon: Provide basic debugging and system trap support.
Hexagon: Add ptrace support
Hexagon: Add time and timer functions
Hexagon: Add interrupts
...
There are plausible reasons for architectures to provide their own
versions of csum_partial_copy_nocheck and csum_tcpudp_magic.
By protecting these, the architecture can still re-use the
asm-generic checksum.h, instead of copying it.

epoll can acquire recursively acquire ep->mtx on multiple "struct
eventpoll"s at once in the case where one epoll fd is monitoring another
epoll fd. This is perfectly OK, since we're careful about the lock
ordering, but it causes spurious lockdep warnings. Annotate the recursion
using mutex_lock_nested, and add a comment explaining the nesting rules
for good measure.
Recent versions of systemd are triggering this, and it can also be
demonstrated with the following trivial test program:
--------------------8<--------------------
int main(void) {
int e1, e2;
struct epoll_event evt = {
.events = EPOLLIN
};
e1 = epoll_create1(0);
e2 = epoll_create1(0);
epoll_ctl(e1, EPOLL_CTL_ADD, e2, &evt);
return 0;
}
--------------------8<--------------------

Some find using utf-8 in commit logs inappropriate.
Some patch commit logs contain unintended utf-8 characters when doing
things like copy/pasting compilation output.
Look for the start of any commit log by skipping initial lines that look
like email headers and "From: " lines.
Stop looking for utf-8 at the first signature line.
