* m68k: include asm/cmpxchg.h in our m68k atomic.hGreg Ungerer2012-04-011-0/+1
| | | | | | | | | | | | | | | | | | | | | | | After commit 9ffc93f203c18a70623f21950f1dd473c9ec48cd ("Remove all CC init/main.o In file included from include/linux/mm.h:15:0, from include/linux/ring_buffer.h:5, from include/linux/ftrace_event.h:4, from include/trace/syscall.h:6, from include/linux/syscalls.h:78, from init/main.c:16: include/linux/debug_locks.h: In function ‘__debug_locks_off’: include/linux/debug_locks.h:16:2: error: implicit declaration of function ‘xchg’ There is no indirect inclusions of the new asm/cmpxchg.h for m68k here. Looking at most other architectures they include asm/cmpxchg.h in their asm/atomic.h. M68k currently does not do this. Including this in atomic.h fixes all m68k build problems.

Some more merging of MMU and non-MMU common files (specifically the arch process.c, ptrace and time.c). And a big cleanup of the massively duplicated ColdFire device definition code. Overall we remove about 2000 lines of code, and end up with a single set of platform device definitions for the serial ports, ethernet ports and QSPI ports common in most ColdFire SoCs. I expect you will get a merge conflict on arch/m68k/kernel/process.c, in cpu_idle(). It should be relatively strait forward to fixup."

* | sock: Introduce the SO_PEEK_OFF sock optionPavel Emelyanov2012-02-211-0/+1
|/ | | | | | | | | | | | | | | | | | | | | | This one specifies where to start MSG_PEEK-ing queue data from. When set to negative value means that MSG_PEEK works as ususally -- peeks from the head of the queue always. When some bytes are peeked from queue and the peeking offset is non negative it is moved forward so that the next peek will return next portion of data. When non-peeking recvmsg occurs and the peeking offset is non negative is is moved backward so that the next peek will still peek the proper data (i.e. the one that would have been picked if there were no non peeking recv in between). The offset is set using per-proto opteration to let the protocol handle the locking issues and to check whether the peeking offset feature is supported by the protocol the socket belongs to.
