2009-09-17mfd: revise locking for pcf50633 ADCPaul Fertser
Current implementation is prone to races, this patch attempts to remove all but one (in pcf50633_adc_sync_read). The idea is that we need to guard the queue access only on inserting and removing items. If we insert and there're no more items in the queue it means that the last irq already happened and we need to trigger ADC manually. If not, then the next conversion will be triggered by the irq handler upon completion of the previous.

2009-09-17mfd: use a dedicated workqueue for pcf50633 irq processingPaul Fertser
Using the default kernel "events" workqueue causes problems with synchronous adc readings if initiated from some task on the same workqueue. I had a deadlock trying to use pcf50633_adc_sync_read from a power_supply class driver because the reading was initiated from the workqueue and it waited for the irq processing to complete (to get the result) and that was put on the same workqueue.

iucv_sock_recvmsg() and iucv_process_message()/iucv_fragment_skb race for dequeuing an skb from the backlog queue.

2009-09-16af_iucv: do not call iucv_sock_kill() twiceHendrik Brueckner
For non-accepted sockets on the accept queue, iucv_sock_kill() is called twice (in iucv_sock_close() and iucv_sock_cleanup_listen()). This typically results in a kernel oops as shown below. Remove the duplicate call to iucv_sock_kill() and set the SOCK_ZAPPED flag in iucv_sock_close() only. The iucv_sock_kill() function frees a socket only if the socket is zapped and orphaned (sk->sk_socket == NULL): - Non-accepted sockets are always orphaned and, thus, iucv_sock_kill() frees the socket twice. - For accepted sockets or sockets created with iucv_sock_create(), sk->sk_socket is initialized. This caused the first call to iucv_sock_kill() to return immediately. To free these sockets, iucv_sock_release() uses sock_orphan() before calling iucv_sock_kill(). <1>Unable to handle kernel pointer dereference at virtual kernel address 000000003edd3000 <4>Oops: 0011 [#1] PREEMPT SMP DEBUG_PAGEALLOC <4>Modules linked in: af_iucv sunrpc qeth_l3 dm_multipath dm_mod qeth vmur ccwgroup <4>CPU: 0 Not tainted 2.6.30 #4 <4>Process iucv_sock_close (pid: 2486, task: 000000003aea4340, ksp: 000000003b75bc68) <4>Krnl PSW : 0704200180000000 000003e00168e23a (iucv_sock_kill+0x2e/0xcc [af_iucv]) <4> R:0 T:1 IO:1 EX:1 Key:0 M:1 W:0 P:0 AS:0 CC:2 PM:0 EA:3 <4>Krnl GPRS: 0000000000000000 000000003b75c000 000000003edd37f0 0000000000000001 <4> 000003e00168ec62 000000003988d960 0000000000000000 000003e0016b0608 <4> 000000003fe81b20 000000003839bb58 00000000399977f0 000000003edd37f0 <4> 000003e00168b000 000003e00168f138 000000003b75bcd0 000000003b75bc98 <4>Krnl Code: 000003e00168e22a: c0c0ffffe6eb larl %r12,3e00168b000 <4> 000003e00168e230: b90400b2 lgr %r11,%r2 <4> 000003e00168e234: e3e0f0980024 stg %r14,152(%r15) <4> >000003e00168e23a: e310225e0090 llgc %r1,606(%r2) <4> 000003e00168e240: a7110001 tmll %r1,1 <4> 000003e00168e244: a7840007 brc 8,3e00168e252 <4> 000003e00168e248: d507d00023c8 clc 0(8,%r13),968(%r2) <4> 000003e00168e24e: a7840009 brc 8,3e00168e260 <4>Call Trace: <4>([<000003e0016b0608>] afiucv_dbf+0x0/0xfffffffffffdea20 [af_iucv]) <4> [<000003e00168ec6c>] iucv_sock_close+0x130/0x368 [af_iucv] <4> [<000003e00168ef02>] iucv_sock_release+0x5e/0xe4 [af_iucv] <4> [<0000000000438e6c>] sock_release+0x44/0x104 <4> [<0000000000438f5e>] sock_close+0x32/0x50 <4> [<0000000000207898>] __fput+0xf4/0x250 <4> [<00000000002038aa>] filp_close+0x7a/0xa8 <4> [<00000000002039ba>] SyS_close+0xe2/0x148 <4> [<0000000000117c8e>] sysc_noemu+0x10/0x16 <4> [<00000042ff8deeac>] 0x42ff8deeac Signed-off-by: Hendrik Brueckner <brueckner@linux.vnet.ibm.com> Signed-off-by: Ursula Braun <ursula.braun@de.ibm.com> Signed-off-by: David S.

2009-09-16iucv: fix iucv_buffer_cpumask check when calling IUCV functionsHendrik Brueckner
Prior to calling IUCV functions, the DECLARE BUFFER function must have been called for at least one CPU to receive IUCV interrupts. With commit "iucv: establish reboot notifier" (6c005961), a check has been introduced to avoid calling IUCV functions if the current CPU does not have an interrupt buffer declared. Because one interrupt buffer is sufficient, change the condition to ensure that one interrupt buffer is available. In addition, checking the buffer on the current CPU creates a race with CPU up/down notifications: before checking the buffer, the IUCV function might be interrupted by an smp_call_function() that retrieves the interrupt buffer for the current CPU. When the IUCV function continues, the check fails and -EIO is returned. If a buffer is available on any other CPU, the IUCV function call must be invoked (instead of failing with -EIO).

2009-09-16Blackfin: increase default async timings for parallel flashesSonic Zhang
The default async timings are a little too fast for the parallel flash that is attached by default to the async banks. So slow things down a bit so accessing the hardware is stable. Signed-off-by: Sonic Zhang <sonic.zhang@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-09-16Blackfin: add ICPLB coverage for async banksBernd Schmidt
When doing XIP, we need to execute out of the async banks, so we need ICPLBs to allow this. Signed-off-by: Bernd Schmidt <bernds_cb1@t-online.de> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-09-16Blackfin: use KERN_ALERT in all kgdb_test outputMingquan Pan
Most messages are already using KERN_ALERT, so be consistent to make things easier to check with test scripts. Signed-off-by: Mingquan Pan <grace.pan@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-09-16Blackfin: workaround anomaly 05000283Robin Getz
Make sure our interrupt entry code with exact hardware errors handles anomaly 05000283 (infinite stall in system MMR kill) so we don't stall while under load. Signed-off-by: Robin Getz <robin.getz@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-09-16Blackfin: use raw_smp_processor_id() in exception codeYi Li
When preempt debugging is enabled, smp_processor_id() may utilize the "current" structure. This may not be safe to access under all exceptions due to it being in dynamically allocated memory. So in exception code, make sure we use raw_smp_processor_id() instead to get at the real value directly. Signed-off-by: Yi Li <yi.li@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-09-16Blackfin: Fix link errors with binutils 2.19 and GCC 4.3Ingo Molnar
Not sure whether this has been reported/fixed before. Today I built a Blackfin tool-chain from scratch for -tip testing, and it triggers: arch/blackfin/kernel/vmlinux.lds:1238: undefined section `.data_a_l1' referenced in expression and: arch/blackfin/kernel/vmlinux.lds:1238: undefined section `.text_data_l1' referenced in expression Now i dont have any way to test this linker script, but it now at least builds fine after fixing what appears to be typos in those assert statements.

2009-09-16Blackfin: optimize fixed code handling for the most common caseMike Frysinger
The majority of the time we are returning to user space, it is not in the fixed atomic code region. So rather than branch to a function where we check the PC and return, do the check inline and branch only when needed. Also, tweak some of the fixed code handling based on assumptions we are aware of but cannot be expressed in C. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-09-16Blackfin: delete '-spi' suffix in ad1836/ad1938 driver nameBarry Song

2009-09-16Blackfin: do not trace the exception handlerYi Li
Since the exception handler cannot cause exceptions, we cannot trace it without easily causing double faults and crashing the system. Signed-off-by: Yi Li <yi.li@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
