2014-11-25arm64: add alternative runtime patchingAndre Przywara
With a blatant copy of some x86 bits we introduce the alternative runtime patching "framework" to arm64. This is quite basic for now and we only provide the functions we need at this time. This is connected to the newly introduced feature bits. Signed-off-by: Andre Przywara <andre.przywara@arm.com> Signed-off-by: Will Deacon <will.deacon@arm.com>
2014-11-25arm64: add cpu_capabilities bitmapAndre Przywara
For taking note if at least one CPU in the system needs a bug workaround or would benefit from a code optimization, we create a new bitmap to hold (artificial) feature bits. Since elf_hwcap is part of the userland ABI, we keep it alone and introduce a new data structure for that (along with some accessors).

2014-11-25ARM: dts: atlas6: Add I2S external clock input pingroupRongjun Ying

2014-11-25Input: xpad - use proper endpoint typeGreg Kroah-Hartman
The xpad wireless endpoint is not a bulk endpoint on my devices, but rather an interrupt one, so the USB core complains when it is submitted.

2014-11-25time: Fix sign bug in NTP mult overflow warningJohn Stultz
In commit 6067dc5a8c2b ("time: Avoid possible NTP adjustment mult overflow") a new check was added to watch for adjustments that could cause a mult overflow. Unfortunately the check compares a signed with unsigned value and ignored the case where the adjustment was negative, which causes spurious warn-ons on some systems (and seems like it would result in problematic time adjustments there as well, due to the early return). Thus this patch adds a check to make sure the adjustment is positive before we check for an overflow, and resovles the issue in my testing.

2014-11-24NFS: fix subtle change in COMMIT behaviorWeston Andros Adamson
Recent work in the pgio layer made it possible for there to be more than one request per page. This caused a subtle change in commit behavior, because write.c:nfs_commit_unstable_pages compares the number of *pages* waiting for writeback against the number of requests on a commit list to choose when to send a COMMIT in a non-blocking flush. This is probably hard to hit in normal operation - you have to be using rsize/wsize < PAGE_SIZE, or pnfs with lots of boundaries that are not page aligned to have a noticeable change in behavior.

For example, sk_buff's protocol is ETH_P_IPV6, but sock's sk_family is AF_INET, in that case, if sk->sk_bound_dev_if is zero, a wrong sock will be returned. the fix is to "continue" the searching, if no matching, return NULL.

2014-11-24perf symbols: Move bfd_demangle stubbing to its only userArnaldo Carvalho de Melo
We need to define bfd_demangle() to either a wrapper for cplus_demangle() or to a stub when NO_DEMANGLE is defined. That is at odds with using bfd.h for some other reason, as it defines bfd_demangle() and then if code that wants to use symbol.h, where the above stubbing/wrapping is done, and bfd.h for other reasons, we end up with a build error where bfd_demangle() is found to be redefined. Avoid that by moving the stubbing/wrapping to symbol-elf.c, that is the only user of such function. If we ever get to a point where there are more valid users, we can then introduce a header for that.

2014-11-24perf callchain: Enable printing the srcline in the historyAndi Kleen
For lbr-as-callgraph we need to see the line number in the history, because many LBR entries can be in a single function, and just showing the same function name many times is not useful. When the history code is configured to sort by address, also try to resolve the address to a file:srcline and display this in the browser. If that doesn't work still display the address. This can be also useful without LBRs for understanding which call in a large function (or in which inlined function) called something else.

2014-11-24scsi: add SPC-3 command definitionsHannes Reinecke
SPC-3 defines SERVICE ACTION IN(12), SERVICE_ACTION OUT(12), SERVICE ACTION OUT(16), and SERVICE ACTION BIDIRECTIONAL. And READ MEDIA SERIAL NUMBER has long since been deprecated. So update callers to refer to the new cdb name.
