2010-03-10libipw: split ieee->networks into small piecesZhu Yi
The ieee->networks consists of 128 struct libipw_network entries. If we allocate this chunk of memory altogether, it ends up with an order 4 page allocation. High order page allocation is likely to fail on system high load. This patch splits the big chunk memory allocation into small pieces, each is 344 bytes, allocates them with 128 times. The patch fixed bug http://bugzilla.kernel.org/show_bug.cgi?id=14989 Signed-off-by: Zhu Yi <yi.zhu@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2010-03-10mac80211: Fix sta_mtx unlocking on insert STA failure pathJouni Malinen
Commit 34e895075e21be3e21e71d6317440d1ee7969ad0 introduced sta_mtx locking into sta_info_insert() (now sta_info_insert_rcu), but forgot to unlock this mutex on one of the error paths. Fix this by adding the missing mutex_unlock() call for the case where STA insert fails due to an entry existing already. This may happen at least in AP mode when a STA roams between two BSSes (vifs).

2010-03-10qeth: no recovery after layer mismatch (z/VM NICs)Ursula Braun
Depending on their definition in z/VM, virtual devices for z/VM VSWITCH or GuestLAN must be configured either in layer2 or in layer3 mode. If qeth detects a layer mismatch, device activation fails. Trying to recover from this error cannot help; thus scheduling a recovery should be avoided. In addition, since recovery is forbidden during online setting of a qeth device, existence of its network device is guaranteed for all dev_close() calls in qeth. The corresponding checks can be removed. Signed-off-by: Ursula Braun <ursula.braun@de.ibm.com> Signed-off-by: Frank Blaschka <frank.blaschka@de.ibm.com> Signed-off-by: David S.

2010-03-09Input: ad7877 - increase pen up imeoutMichael Hennerich
The time interval between consecutive interrupts depends on a number of tunables: first_conversion_delay, acquisition_time, averaging and foremost the pen_down_acc_interval. Since the mod_timer() action for the PEN UP event happens in the spi_async() callback function, latencies incurred by the spi bus drivers also need to be taken into account. So all in all, give the PEN UP event a bit more wiggle room and increase timeout to 100ms.

The AD7873 is almost identical to the ADS7846; the only difference is related to the Power Management bits PD0 and PD1. This results in a slightly different PENIRQ enable behavior. For the AD7873, VREF should be turned off during differential measurements. So, add the AD7873/43 to the list of driver supported devices, and prevent VREF usage during differential/ratiometric conversion modes.

This reverts commit 21b2d8bd2f0d4e0f21ade147fd193c8b9c1fd2b9. As explained by Johannes: When we build a probe request frame in the buffer with the SSID, we could arrive over the limit of 200 bytes. When we build it in the buffer without the SSID (wildcard) we don't arrive over 200 bytes, but the ucode still allows direct probe in addition because it has an internal buffer that is larger when it inserts the SSID...

2010-03-09iwl3945: fix memory corruptionReinette Chatre
Recent patch "iwlwifi: move 3945 clip groups to 3945 data" exposed a memory corruption problem. When initializing the clip groups the code was mistakenly using the iwlagn rate count, not the 3945 rate count. This resulted in more memory being written than was allocated. "iwlwifi: move 3945 clip groups to 3945 data" moved the location where the clip groups are stored and the impact is now severe in that the number of configured TX queues is modified. Previously the "temperature" field was overwritten, which did not seem to affect the operation. Fix this one instance where wrong rate count was used. I also noticed one more location where the iwlagn rate count was used to index an iwl3945 array, fix this. I also modified one location that modified the iwlagn rate count to obtain the iwl3945 rate count ... just use the iwl3945 rate count directly.

2010-03-09udf: Fix unalloc space handling in udf_update_inodeJan Kara

Another fix for the extended ptrace patches in the -next tree. The handling of breakpoints and watchpoints is inconsistent. When a breakpoint or watchpoint is hit, the interrupt handler is clearing the proper bits in the dbcr* registers, but leaving the dac* and iac* registers alone. The ptrace code to delete the break/watchpoints checks the dac* and iac* registers for zero to determine if they are enabled. Instead, they should check the dbcr* bits.

2010-03-09powerpc: Dynamically allocate pacasMichael Ellerman
On 64-bit kernels we currently have a 512 byte struct paca_struct for each cpu (usually just called "the paca"). Currently they are statically allocated, which means a kernel built for a large number of cpus will waste a lot of space if it's booted on a machine with few cpus. We can avoid that by only allocating the number of pacas we need at boot. However this is complicated by the fact that we need to access the paca before we know how many cpus there are in the system. The solution is to dynamically allocate enough space for NR_CPUS pacas, but then later in boot when we know how many cpus we have, we free any unused pacas.
