2010-07-05ARM: SAMSUNG: Fix on wrong function name for S5PV210 sdhci0Hyuk Lee
This patch fixes on wrong function name in include/plat/sdhci.h for Samsung. The 's5pc100_default_sdhci0()' function should be chnaged to 's5pv210_default_sdhci0()'. Because 's5pv210_default_sdhci0()' must be pair. Signed-off-by: Hyuk Lee <hyuk1.lee@samsung.com> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>

2010-07-05ARM: S5PV210: Correct clock register propertiesMyungJoo Ham
1. Corrected shift values of I2S and UART clocks (CLK_GATE_IP3), which were defined incorrectly. 2. Corrected shift values of sclk_audio, uclk1, sclk_fimd, sclk_mmc, sclk_spi, sclk_pwm, which had duplicated .enable/.ctrlbit with their twins defined in struct clk init_clocks_disable[] and struct clk init_clocks[]. We've changed their .enable/.ctrlbit to use CLK_SRC_MASK register to avoid the duplicated clock problem described below. NOTE: Duplicated Clock Problem Please note that each clock definition should access different control register; otherwise, the system may suffer lockups. For example, if we have two clock definitions "a" and "b" which access the same register (and the shift value). Then, when we do: module A clk = clk_get("a"); clk->clk_enable(clk); module B (context switch) clk = clk_get("b"); clk->clk_enable(clk); do something with clk. clk->clk_disable(clk); module A (context switch) do something with clk * At this point, the system may hang. Therefore, there should be no clock definitions with the same contol register/shift. If we need to create "aliases", then, creating child clocks sharing the clock should be fine. 3. Corrected other sclk_* shift values and access registers.

We should initialize the module dynamic debug datastructures only after determining that the module is not loaded yet.

2010-07-04ARM: 6205/1: perf: ensure counter delta is treated as unsignedWill Deacon
Hardware performance counters on ARM are 32-bits wide but atomic64_t variables are used to represent counter data in the hw_perf_event structure. The armpmu_event_update function right-shifts a signed 64-bit delta variable and adds the result to the event count. This can lead to shifting in sign-bits if the MSB of the 32-bit counter value is set. This results in perf output such as: Performance counter stats for 'sleep 20': 18446744073460670464 cycles <-- 0xFFFFFFFFF12A6000 7783773 instructions # 0.000 IPC 465 context-switches 161 page-faults 1172393 branches 20.154242147 seconds time elapsed This patch ensures that the delta value is treated as unsigned so that the right shift sets the upper bits to zero.

2010-07-02s2io: resolve statistics issuesJon Mason
This patch resolves a number of issues in the statistics gathering of the s2io driver. On Xframe adapters, the received multicast statistics counter includes pause frames which are not indicated to the driver. This can cause issues where the multicast packet count is higher than what has actually been received, possibly higher than the number of packets received. The driver software counters are replaced with the adapter hardware statistics for rx_packets, rx_bytes, and tx_bytes. It also uses the overflow registers to determine if the statistics wrapped the 32bit register (removing the window of having a statistic value less than the previous call). rx_length_errors statistic now includes undersized packets in addition to oversized packets in its counting. Finally, rx_crc_errors are now being counted. Signed-off-by: Jon Mason <jon.mason@exar.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2010-07-02net: decreasing real_num_tx_queues needs to flush qdiscJohn Fastabend
Reducing real_num_queues needs to flush the qdisc otherwise skbs with queue_mappings greater then real_num_tx_queues can be sent to the underlying driver. The flow for this is, dev_queue_xmit() dev_pick_tx() skb_tx_hash() => hash using real_num_tx_queues skb_set_queue_mapping() ... qdisc_enqueue_root() => enqueue skb on txq from hash ... dev->real_num_tx_queues -= n ... sch_direct_xmit() dev_hard_start_xmit() ndo_start_xmit(skb,dev) => skb queue set with old hash skbs are enqueued on the qdisc with skb->queue_mapping set 0 < queue_mappings < real_num_tx_queues. When the driver decreases real_num_tx_queues skb's may be dequeued from the qdisc with a queue_mapping greater then real_num_tx_queues. This fixes a case in ixgbe where this was occurring with DCB and FCoE. Because the driver is using queue_mapping to map skbs to tx descriptor rings we can potentially map skbs to rings that no longer exist.

As Nehalem/Nehalem-EP/Westmere devices uses several devices for the same functionality (memory controller), the default way of proping devices doesn't work. So, instead of a per-device probe, all devices should be probed at once. This means that we should block any new attempt of probe, otherwise, it will try to register the same device several times.

2010-07-01drm/i915: take struct_mutex in i915_dma_cleanup()Dan Carpenter
intel_cleanup_ring_buffer() calls drm_gem_object_unreference() (as opposed to drm_gem_object_unreference_unlocked()) so it needs to be called with "struct_mutex" held. If we don't hold the lock, it triggers a BUG_ON(!mutex_is_locked(&dev->struct_mutex)); I also audited the other places that call intel_cleanup_ring_buffer() and they all hold the lock so they're OK. This was introduced in: 8187a2b70e3 "drm/i915: introduce intel_ring_buffer structure (V2)" and it's a regression from v2.6.34.

2010-07-01drm/i915: Fix CRT hotplug regression in 2.6.35-rc1Andy Lutomirski
Commit 7a772c492fcfffae812ffca78a628e76fa57fe58 has two bugs which made the hotplug problems on my laptop worse instead of better. First, it did not, in fact, disable the CRT plug interrupt -- it disabled all the other hotplug interrupts. It seems rather doubtful that that bit of the patch fixed anything, so let's just remove it. (If you want to add it back, you probably meant ~CRT_HOTPLUG_INT_EN.) Second, on at least my GM45, setting CRT_HOTPLUG_ACTIVATION_PERIOD_64 and CRT_HOTPLUG_VOLTAGE_COMPARE_50 (when they were previously unset) causes a hotplug interrupt about three seconds later. The old code never restored PORT_HOTPLUG_EN so this could only happen once, but they new code restores those registers. So just set those bits when we set up the interrupt in the first place.
