* pstore: make pstore write function return normal success/fail valueChen Gong2011-10-12
| | | | | | | | | | | Currently pstore write interface employs record id as return value, but it is not enough because it can't tell caller if the write operation is successful. Pass the record id back via an argument pointer and return zero for success, non-zero for failure. Signed-off-by: Chen Gong <gong.chen@linux.intel.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
* pstore: change mutex locking to spin_locksDon Zickus2011-08-16
| | | | | | | | | | | | | | | | | | | | pstore was using mutex locking to protect read/write access to the backend plug-ins. This causes problems when pstore is executed in an NMI context through panic() -> kmsg_dump(). This patch changes the mutex to a spin_lock_irqsave then also checks to see if we are in an NMI context. If we are in an NMI and can't get the lock, just print a message stating that and blow by the locking. All this is probably a hack around the bigger locking problem but it solves my current situation of trying to sleep in an NMI context. Tested by loading the lkdtm module and executing a HARDLOCKUP which will cause the machine to panic inside the nmi handler.

| | | | | | | | | | | | | | | | | | | | 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: check host->clock before using it as a denominatorAndy Shevchenko2011-08-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| * | usb: serial: ftdi_sio.c: For the FT232H FTDI_SIO_SET_BAUDRATE_REQUEST, index ↵Uwe Bonnes2011-08-08

See gmane.linux.usb.general: "[ftdi_sio] FT232H support". With the old code, the MSB of the 4 encoded fractional divider bits and more important the clock predivider bits got lost. Adding the FT232H to the code patch were these bits are shifted solves the problem. I verified baud rates with a scope now. I suspect, that the BM device probably needs these bits shifted too. But there is no predivider bit, so this is not obvious, and a missing MSB of the encoded fractional divider only shifts the resulting baudrate minimal. The AM has only 3 bits of encoded fractional divider, so it is not impacted. I have no BM device to test, so I only added a comment and left the code for the BM untouched.

Essentially, the patch changes the hid gadget such that a request for the HID descriptor is handled by copying the descriptor into the response buffer, rather than falling through the default case, in which the request is answered by a STALL.
