2011-08-15ASoC: Add spi hw read function for 16 addr 8 data mode for ad193x fixScott Jiang1-0/+23
[This will be used by the ad193x driver to fix the fact that the original author of the driver put a bodge for their particular chip into a the generic ASoC register I/O abstraction layer which looked like an obvious bug which ended up getting fixed in 3.0. Sadly there were no comments documenting what was going on. A minimally invasive correction to the driver is to remove the register cache support and go direct to the hardware all the time so we're adding a new feature -- broonie] Signed-off-by: Scott Jiang <[email protected]> Signed-off-by: Mark Brown <[email protected]>

2011-08-15ARM: 7015/1: ARM errata: Possible cache data corruption with hit-under-miss ↵Catalin Marinas2-0/+28
enabled This patch is a workaround for the 364296 ARM1136 r0p2 erratum (possible cache data corruption with hit-under-miss enabled). It sets the undocumented bit 31 in the auxiliary control register and the FI bit in the control register, thus disabling hit-under-miss without putting the processor into full low interrupt latency mode.

2011-08-15ARM: 7014/1: cache-l2x0: Fix L2 Cache size calculation.Srinivas Kandagatla1-1/+1
This patch fixes L2 Cache size calculations for L2C-210, L2C-310 and PL310, by changing the L2X0_AUX_CTRL_WAY_SIZE_MASK from 2 bits to 3 bits. The Auxiliary Control Register for L2C-210, L2C-310 and PL310 has 3bits [19:17] for Way size, however the existing code only uses 2 bits to get this value. This results in incorrect cachesize calculations. It also results in performing operations on the whole cache when we erroneously decide that the range is big enough (due to l2x0_size being too small) and also prints incorrect cachesize.

2011-08-15drm/radeon/kms: don't try to be smart in the hpd handlerAlex Deucher3-8/+19
Attempting to try and turn off disconnected display hw in the hotput handler lead to more problems than it helped. For now just register an event and only attempt the do something interesting with DP. Other connectors are just too problematic: - Some systems have an HPD pin assigned to LVDS, but it's rarely if ever connected properly and we don't really care about hpd events on LVDS anyway since it's always connected. - The HPD pin is wired up correctly for eDP, but we don't really have to do anything since the events since it's always connected. - Some HPD pins fire more than once when you connect/disconnect - etc. Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=39882 Signed-off-by: Alex Deucher <[email protected]> Cc: [email protected] Signed-off-by: Dave Airlie <[email protected]>

2011-08-15lguest: allow booting guest with CONFIG_RELOCATABLE=yRusty Russell1-0/+3
The CONFIG_RELOCATABLE code tries to align the unpack destination to the value of 'kernel_alignment' in the setup_hdr. If that's 0, it tries to unpack to address 0, which in fact causes the gunzip code to call 'error("Out of memory while allocating output buffer")'. The bootloader (ie. the lguest Launcher in this case) should be doing setting this field; the normal bzImage is 16M, we can use the same.

2011-08-14mm: fix wrong vmap address calculations with odd NR_CPUS valuesClemens Ladisch1-3/+4
Commit db64fe02258f ("mm: rewrite vmap layer") introduced code that does address calculations under the assumption that VMAP_BLOCK_SIZE is a power of two. However, this might not be true if CONFIG_NR_CPUS is not set to a power of two. Wrong vmap_block index/offset values could lead to memory corruption. However, this has never been observed in practice (or never been diagnosed correctly); what caught this was the BUG_ON in vb_alloc() that checks for inconsistent vmap_block indices. To fix this, ensure that VMAP_BLOCK_SIZE always is a power of two. BugLink: https://bugzilla.kernel.org/show_bug.cgi?id=31572 Reported-by: Pavel Kysilka <[email protected]> Reported-by: Matias A.

2011-08-14ALSA: snd_usb_caiaq: track submitted output urbsDaniel Mack2-4/+28
The snd_usb_caiaq driver currently assumes that output urbs are serviced in time and doesn't track when and whether they are given back by the USB core. That usually works fine, but due to temporary limitations of the XHCI stack, we faced that urbs were submitted more than once with this approach. As it's no good practice to fire and forget urbs anyway, this patch introduces a proper bit mask to track which requests have been submitted and given back. That alone however doesn't make the driver work in case the host controller is broken and doesn't give back urbs at all, and the output stream will stop once all pre-allocated output urbs are consumed. But it does prevent crashes of the controller stack in such cases. See http://bugzilla.kernel.org/show_bug.cgi?id=40702 for more details.

2011-08-13drivers/net/can/sja1000/plx_pci.c: eliminate double freeJulia Lawall1-2/+2
In this code, the failure_cleanup label calls the function plx_pci_del_card, which frees everything in the card->net_dev array. dev is placed in this array immediately after allocation, so the two subsequent jumps to failure_cleanup should not also call free_sja1000dev, but the second one does. If plx_pci_check_sja1000 fails, then free_sja1000dev is also called on dev. Because dev is already in the card->net_dev array, this implies that when plx_pci_del_card is later called, it may get freed again. So that entry is reset to NULL after the free. Finally, if there is a problem with one channel, there will be a hole in the array. card->channels counts the number of channels that have succeeded, and does not keep track of the index of the largest element in the array that is valid. So the loop in plx_pci_del_card is changed to go up to PLX_PCI_MAX_CHAN, which is only 2. Signed-off-by: Julia Lawall <[email protected]> Signed-off-by: David S. Miller <[email protected]>

2011-08-13mmc: dw_mmc: Fix DDR mode support.Seungwon Jeon1-2/+2
Host driver can't get a hint of DDR mode through ios->ddr flag anymore. ios->timing is currently used to inform DDR mode as a substitute. And capability of MMC_CAP_MMC_HIGHSPEED is added for DDR support.

2011-08-13mmc: sdhci: use f_max instead of host->clock for timeoutsAndy Shevchenko1-5/+2
When timeout_clk is calculated the host->clock could be zero. So, instead of host->clock the calculation now uses mmc->f_max. Signed-off-by: Andy Shevchenko <[email protected]> Cc: Mark Brown <[email protected]> Signed-off-by: Chris Ball <[email protected]>
2011-08-13mmc: sdhci: move timeout_clk calculation farther downAndy Shevchenko1-19/+19
This moves the calculation below the assignment of mmc->f_max, which we need for calculating timeout_clk in the next patch in this series. Signed-off-by: Andy Shevchenko <[email protected]> Signed-off-by: Chris Ball <[email protected]>
2011-08-13mmc: sdhci: check host->clock before using it as a denominatorAndy Shevchenko1-3/+5
Sometimes host->clock could be zero which is a legal situation. This patch checks host->clock before usage as a denominator when timeout is calculated. A similar patch is applied for mmc core (see commit e9b8684, "mmc: fix division by zero in MMC core"). Without this patch, the execution of the sdhci_calc_timeout could end up with a backtrace: <0>[ 4.014319] divide error: 0000 [#1] PREEMPT SMP <4>[ 4.014352] Modules linked in: g_ether <4>[ 4.014376] <4>[ 4.014393] Pid: 33, comm: kworker/u:2 Not tainted 3.0.0+ #646 <4>[ 4.014421] EIP: 0060:[<c12fa38e>] EFLAGS: 00010046 CPU: 1 <4>[ 4.014449] EIP is at sdhci_calc_timeout+0x2e/0x100 <4>[ 4.014468] EAX: 00000000 EBX: f5930fc8 ECX: 00000000 EDX: 00000000 <4>[ 4.014488] ESI: f5291de8 EDI: f5291db8 EBP: f5291c6c ESP: f5291c50 <4>[ 4.014508] DS: 007b ES: 007b FS: 00d8 GS: 0000 SS: 0068 <0>[ 4.014529] Process kworker/u:2 (pid: 33, ti=f5290000 task=f53065a0 task.ti=f5290000) <0>[ 4.014546] Stack: <4>[ 4.014557] 00000082 c1054fdd f5291c78 04000000 f5930fc8 f5291de8 f5291db8 f5291cac <4>[ 4.014611] c12fab7c c107a98b f5291c88 c13b6d3f f593109c f5882000 f5291cac c1054fdd <4>[ 4.014663] 00000000 00000000 f5882000 00000082 f5930fc8 f5291db8 0000000a f5291ccc <0>[ 4.014716] Call Trace: <4>[ 4.014743] [<c1054fdd>] ? mod_timer+0x11d/0x380 <4>[ 4.014770] [<c12fab7c>] sdhci_prepare_data+0x2c/0x3a0 <4>[ 4.014798] [<c107a98b>] ? trace_hardirqs_off+0xb/0x10 <4>[ 4.014827] [<c13b6d3f>] ? _raw_spin_unlock_irqrestore+0x2f/0x60 <4>[ 4.014854] [<c1054fdd>] ? mod_timer+0x11d/0x380 <4>[ 4.014880] [<c12fc7db>] sdhci_send_command+0xdb/0x210 <4>[ 4.014906] [<c12fd5f3>] sdhci_request+0xc3/0x150 <4>[ 4.014932] [<c12ec56a>] mmc_start_request+0xda/0x200 <4>[ 4.014960] [<c120d7c2>] ? __raw_spin_lock_init+0x32/0x60 <4>[ 4.014989] [<c1066a85>] ? __init_waitqueue_head+0x35/0x50 <4>[ 4.015015] [<c12ec70b>] mmc_wait_for_req+0x7b/0x90 <4>[ 4.015045] [<c12f0c67>] mmc_send_cxd_data+0xf7/0x130 <4>[ 4.015076] [<c12ecbc0>] ? mmc_erase+0x140/0x140 <4>[ 4.015102] [<c12f139d>] mmc_send_ext_csd+0x1d/0x20 <4>[ 4.015125] [<c12efef0>] mmc_get_ext_csd+0x70/0x140 <4>[ 4.015151] [<c12effe8>] mmc_compare_ext_csds+0x28/0x190 <4>[ 4.015176] [<c12f039f>] mmc_init_card+0x24f/0x650 <4>[ 4.015201] [<c13b6d5d>] ? _raw_spin_unlock_irqrestore+0x4d/0x60 <4>[ 4.015226] [<c107fd9c>] ? trace_hardirqs_on_caller+0x11c/0x160 <4>[ 4.015255] [<c12f09a4>] mmc_attach_mmc+0xa4/0x190 <4>[ 4.015282] [<c12ee3f0>] mmc_rescan+0x210/0x240 <4>[ 4.015311] [<c105f9b6>] process_one_work+0x176/0x550 <4>[ 4.015336] [<c105f93a>] ? process_one_work+0xfa/0x550 <4>[ 4.015360] [<c12ee1e0>] ? mmc_init_erase+0x140/0x140 <4>[ 4.015385] [<c1061c2a>] worker_thread+0x12a/0x2c0 <4>[ 4.015410] [<c1061b00>] ? manage_workers.clone.18+0x100/0x100 <4>[ 4.015437] [<c1066244>] kthread+0x74/0x80 <4>[ 4.015463] [<c10661d0>] ? __init_kthread_worker+0x60/0x60 <4>[ 4.015490] [<c13b7dfa>] kernel_thread_helper+0x6/0xd <0>[ 4.015507] Code: 57 89 d7 56 53 89 c3 83 ec 10 8b 40 04 8b 72 28 f6 c4 10 89 45 f0 0f 85 91 00 00 00 85 f6 0f 84 c1 00 00 00 8b 4e 04 31 d2 89 c8 <f7> 73 58 ba d3 4d 62 10 89 c1 8b 06 f7 e2 c1 ea 06 01 d1 f7 45 <0>[ 4.015829] EIP: [<c12fa38e>] sdhci_calc_timeout+0x2e/0x100 SS:ESP 0068:f5291c50 Reported-by: Alexander Shishkin <[email protected]> Signed-off-by: Andy Shevchenko <[email protected]> Signed-off-by: Chris Ball <[email protected]>
