2010-04-09Revert "memory-hotplug: add 0x prefix to HEX block_size_bytes"Linus Torvalds
This reverts commit ba168fc37dea145deeb8fa9e7e71c748d2e00d74. It changes user-visible sysfs interfaces, and breaks some existing user space applications which apparently rely on the fact that the output does not contain the "0x" prefix.

2010-04-09[S390] sclp_async: potential buffer overflowDan Carpenter
"len" hasn't been properly range checked so we shouldn't use it as an array offset. This can only be written to by root but it would still be annoying to accidentally write more than 3 characters and corrupt your memory.

2010-04-09drm/nv50: punt hotplug irq handling out to workqueueBen Skeggs

2010-04-09drm/nv50: preserve an unknown SOR_MODECTRL value for DP encodersBen Skeggs
This value interacts with some registers we don't currently know how to program properly ourselves. The default of 5 that we were using matches what the VBIOS on early DP cards do, but later ones use 6, which would cause nouveau to program an incorrect mode on these chips.

2010-04-09drm/nv40: rework lvds table parsingBen Skeggs
All indications seem to be that the version 0x30 table should be handled the same way as 0x40 (as used on G80), at least for the parts that we currently try use. This commit cleans up the parsing to make it clearer about what we're actually trying to achieve, and unifies the 0x30/0x40 parsing. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2010-04-09drm/nouveau: detect vram amount once, and save the valueBen Skeggs

2010-04-08ath5k: add bounds check to pdadc tableBob Copeland
We check the bounds on pdadc once when correcting for negative curves but not when we later copy values from from the pdadc_tmp array, leading to a potential overrun.

2010-04-08ath5k: fix race condition in tx desc processingBob Copeland
As pointed out by Benoit Papillault, there is a potential race condition between the host and the hardware in reading the next link in the transmit descriptor list: cpu0 hw tx for buf completed raise tx_ok interrupt process buf buf->ds_link = 0 read buf->ds_link This change checks txdp before processing a descriptor (if there are any subsequent descriptors) to see if hardware moved on. We'll then process this descriptor on the next tasklet. Signed-off-by: Bob Copeland <me@bobcopeland.com> Acked-by: Bruno Randolf <br1@einfach.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2010-04-08ath5k: clean up queue manipulationBob Copeland
Review spotted a couple of strange invocations to ieee80211_wake_queues that could potentially cause problems: - queues are awakened in the calibration tasklet before phy calibration, and then again after calibration - queues are awakened inside reset when we're trying to drain the ath5k transmit queues, and again after reset is completed (in callers to ath5k_reset_wake). In both cases the first wake is unnecessary, so remove it. Signed-off-by: Bob Copeland <me@bobcopeland.com> Acked-by: Bruno Randolf <br1@einfach.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2010-04-08ath5k: correct channel setting for 2.5 mhz spacingBob Copeland
These channels aren't selectable anyway, but our calculations for 2.5 mhz frequencies are incorrect. The value is supposed to be: (frequency - reference) * (10/25) i.e., divide by 2.5, but we were instead doing: (10 * frequency - reference) / 25. Additionally, the check for (frequency % 5 == 2) had an extra subtraction that wasn't in madwifi HAL.

2010-04-08rt2x00: use rt2800_config_channel_rt3x for rt2872Helmut Schaa
rt2872 needs the same rf register setup as rt3070 and rt3090, hence use rt2800_config_channel_rt3x instead of rt2800_config_channel_rt2x. This change allows me to actually switch channels and hence scan all configured channels on the RT305x SoC platform (which uses a rt2872) here.

2010-04-08ath9k: simplify AR9220 fixup code for AR_AN_TOP2 registerPavel Roskin
Don't modify ah->iniModes, it's supposed to be constant. Instead, apply the fixup when the data is written to the registers. Change ath9k_hw_init_eeprom_fix() to only determine whether the fixup is needed. This allows similteneous support for AR9220 cards that need AR_AN_TOP2 fixup (such as Ubiquiti SR71-12) and those that don't need it (D-Link DWA-552 rev A2).

2010-04-08ath9k_htc: Fix module unloading issueSujith
