* block: separate priority boosting from REQ_METAChristoph Hellwig2011-08-231-0/+3
| | | | | | | | | | | | Add a new REQ_PRIO to let requests preempt others in the cfq I/O schedule, and lave REQ_META purely for marking requests as metadata in blktrace. All existing callers of REQ_META except for XFS are updated to also set REQ_PRIO for now.

* mmc: dw_mmc: Fix DDR mode support.Seungwon Jeon2011-08-131-2/+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.

* mmc: sdhci: use f_max instead of host->clock for timeoutsAndy Shevchenko2011-08-131-5/+2
| | | | | | | | | When timeout_clk is calculated the host->clock could be zero. So, instead of host->clock the calculation now uses mmc->f_max.

* mmc: sdhci: check host->clock before using it as a denominatorAndy Shevchenko2011-08-131-3/+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 <alexander.shishkin@linux.intel.com> Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: Chris Ball <cjb@laptop.org>

To prevent mm.h inclusion via other channels also extract "enum dma_data_direction" definition into separate header. This tiny piece is what gluing netdevice.h with mm.h via "netdevice.h => dmaengine.h => dma-mapping.h => scatterlist.h => mm.h". Removal of mm.h from scatterlist.h was tried and was found not feasible on most archs, so the link was cutoff earlier. Hope people are OK with tiny include file. Note, that mm_types.h is still dragged in, but it is a separate story. Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

We have now also made improvements to the SDIO powerup routine which could possibly mask this kind of issue in future. Add debug messages to the runtime PM hooks so that it is easy to verify if and when runtime PM is happening. Signed-off-by: Daniel Drake <dsd@laptop.org> Signed-off-by: Chris Ball <cjb@laptop.org>

The problem is that runtime PM is disabled during this process, and when we reach mmc_sdio_remove, calling the runtime PM functions here (validly) return errors, and this was causing us to skip the remove function. Fix this by ignoring the error value of pm_runtime_get_sync(), which can return valid errors. This also matches the behaviour of pci_device_remove().

Previously, if div2 was 0 then the value for TIMING_CLOCK_RATE would have been 255 instead of 0. The limits for div1 (TIMING_CLOCK_DIVIDE) and div2 (TIMING_CLOCK_RATE+1) were also not correctly defined. Can easily be reproduced on mx23evk: default clock for high speed sdio cards is 50 MHz. With a SSP_CLK of 28.8 MHz default), this resulted in an actual clock rate of about 56 kHz. Tested on mx23evk.

Each of them contains a bug. The SYSCTL register should be read before writing to it in omap_hsmmc_context_restore() to retain the state of the reserved bits. Before setting the clock divisor and DTO bits the value from the SYSCTL register should be masked properly. We were lucky to have no problems with DTO bits. So, make sure we have clear DTO bits properly in omap_hsmmc_set_ios(). Additionally get rid of msleep(1). The actual time is rarely higher than 30us on OMAP 3630. The resulting pieces of code are refactored into the omap_hsmmc_set_clock() function.
