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. Signed-off-by:

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<-------------------- Reported-by:Paul Bolle <pebolle@tiscali.nl> Tested-by:

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. Signed-off-by:
