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.

2014-11-24net/ping: handle protocol mismatching scenarioJane Zhou
ping_lookup() may return a wrong sock if sk_buff's and sock's protocols dont' match. 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.

CONFIG2_FENAB ('feature enable') changed definition between chip revisions, from 'Latch SCSI Phase' to 'Latch SCSI Phase, display chip ID upon reset, and enable 24 bit addresses'. So only enable it for am53c974 where we know what it's doing. Acked-by: David S.

2014-11-24esp_scsi: let DMA driver provide a config2 valuePaolo Bonzini
On PCscsi, the FENAB configuration also enables 24-bit DMA transfer lengths (and provides the chip id in TCHI after reset). We want to be able to enable this parameter from the DMA driver. Check if the caller of scsi_esp_register provided a value for esp->config2. If this is the case, assume this is not an ESP100, skip the detection phase and leave esp->config2 untouched. It will be used in esp_reset_esp. Reviewed-by: Hannes Reinecke <hare@suse.de> Acked-by: David S.

2014-11-24esp_scsi: correctly detect am53c974Hannes Reinecke
The am53c974 returns the same ID as the FAS236, but implements things slightly differently. So detect the am53c974 by checking for ESP_CONFIG4 register. Reviewed-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Hannes Reinecke <hare@suse.de> Signed-off-by: Christoph Hellwig <hch@lst.de>
2014-11-24am53c974: BLAST residual handlingHannes Reinecke
The am53c974 has an design issue where a single byte might be left in the SCSI FIFO after a DMA transfer. As the handling code is currently untested add a WARN_ON() statement here.
