2010-06-23qeth: fix use after free for qeths debug areaCarsten Otte
The function qeth_free_buffer_pool is called _after_ the per-card debug area has been released. This debug message is not all that usefull anyway, and thus gets removed.

2010-06-23qeth: Fold qeth_qerr debug areaCarsten Otte
This patch removes the qerr debug area. Most info that goes in here is logged to the card's local debug area already, those duplicates are removed. All other elements are moved to the card's local debug area. Signed-off-by: Carsten Otte <cotte@de.ibm.com> Signed-off-by: Frank Blaschka <frank.blaschka@de.ibm.com> Signed-off-by: David S.

2010-06-23qeth: Fold qeth_misc debug areaCarsten Otte
This patch removes the misc debug area. Instead of logging the entire skb we just log a pointer to it into the card's local debug area in qeth_core_get_next_skb. Other then that, this debug area is not used anywhere. Signed-off-by: Carsten Otte <cotte@de.ibm.com> Signed-off-by: Frank Blaschka <frank.blaschka@de.ibm.com> Signed-off-by: David S.

2010-06-23qeth: Fold qeth_trace debug areaCarsten Otte
This patch removes the qeth_trace debug area. All relevant data is logged into either qeth_setup or into each card's own debug area. Superfluous information (such as the card number when logging into the card's own debug area) is removed without replacement.

2010-06-23qeth: Add new s390 debug feature for each qeth cardCarsten Otte
This patch adds a debug area for each qeth card. This debug area will replace various other debug areas that are global for all cards handled by the device driver. On crash dump analysis this makes life easier when trying to find out what's going on with an interface. Also, the forest of debug areas for this device driver is significantly cleared up.

2010-06-23bridge: 64bit rx/tx countersEric Dumazet
Use u64_stats_sync infrastructure to provide 64bit rx/tx counters even on 32bit hosts. It is safe to use a single u64_stats_sync for rx and tx, because BH is disabled on both, and we use per_cpu data. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.

2010-06-23net: Introduce u64_stats_sync infrastructureEric Dumazet
To properly implement 64bits network statistics on 32bit or 64bit hosts, we provide one new type and four methods, to ease conversions. Stats producer should use following template granted it already got an exclusive access to counters (include/linux/u64_stats_sync.h contains some documentation about details) u64_stats_update_begin(&stats->syncp); stats->bytes64 += len; stats->packets64++; u64_stats_update_end(&stats->syncp); While a consumer should use following template to get consistent snapshot : u64 tbytes, tpackets; unsigned int start; do { start = u64_stats_fetch_begin(&stats->syncp); tbytes = stats->bytes64; tpackets = stats->packets64; } while (u64_stats_fetch_retry(&stats->lock, syncp)); Suggested by David Miller, and comments courtesy of Nick Piggin.

2010-06-23net: consolidate netif_needs_gso() checksJohn Fastabend
netif_needs_gso() is checked twice in the TX path once, before submitting the skb to the qdisc and once after it is dequeued from the qdisc just before calling ndo_hard_start(). This opens a window for a user to change the gso/tso or tx checksum settings that can cause netif_needs_gso to be true in one check and false in the other. Specifically, changing TX checksum setting may cause the warning in skb_gso_segment() to be triggered if the checksum is calculated earlier. This consolidates the netif_needs_gso() calls so that the stack only checks if gso is needed in dev_hard_start_xmit().

2010-06-20caif: Add debug connection type for CAIF.Sjur Braendeland
Added new CAIF protocol type CAIFPROTO_DEBUG for accessing CAIF debug on the ST Ericsson modems. There are two debug servers on the modem, one for radio related debug (CAIF_RADIO_DEBUG_SERVICE) and the other for communication/application related debug (CAIF_COM_DEBUG_SERVICE).
