2010-05-19crypto: skcipher - Add ablkcipher_walk interfacesDavid S. Miller
These are akin to the blkcipher_walk helpers. The main differences in the async variant are: 1) Only physical walking is supported. We can't hold on to kmap mappings across the async operation to support virtual ablkcipher_walk operations anyways. 2) Bounce buffers used for async more need to be persistent and freed at a later point in time when the async op completes. Therefore we maintain a list of writeback buffers and require that the ablkcipher_walk user call the 'complete' operation so we can copy the bounce buffers out to the real buffers and free up the bounce buffer chunks. These interfaces will be used by the new Niagara2 crypto driver. Signed-off-by: David S. Miller <davem@davemloft.net> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2010-05-19crypto: testmgr - Add testing for async hashing and update/finalDavid S. Miller

2010-05-19crypto: tcrypt - Add speed tests for async hashingDavid S. Miller
These are invoked in the 'mode' range of 400 to 499. The cost of async vs. sync for the software algorithm implementations varies. It can be as low as 16 cycles but as much as a couple hundred. Here two runs of md5 testing, async then sync: testing speed of async md5 test 0 ( 16 byte blocks, 16 bytes per update, 1 updates): 2448 cycles/operation, 153 cycles/byte test 1 ( 64 byte blocks, 16 bytes per update, 4 updates): 4992 cycles/operation, 78 cycles/byte test 2 ( 64 byte blocks, 64 bytes per update, 1 updates): 3808 cycles/operation, 59 cycles/byte test 3 ( 256 byte blocks, 16 bytes per update, 16 updates): 14000 cycles/operation, 54 cycles/byte test 4 ( 256 byte blocks, 64 bytes per update, 4 updates): 8480 cycles/operation, 33 cycles/byte test 5 ( 256 byte blocks, 256 bytes per update, 1 updates): 7280 cycles/operation, 28 cycles/byte test 6 ( 1024 byte blocks, 16 bytes per update, 64 updates): 50016 cycles/operation, 48 cycles/byte test 7 ( 1024 byte blocks, 256 bytes per update, 4 updates): 22496 cycles/operation, 21 cycles/byte test 8 ( 1024 byte blocks, 1024 bytes per update, 1 updates): 21232 cycles/operation, 20 cycles/byte test 9 ( 2048 byte blocks, 16 bytes per update, 128 updates): 117184 cycles/operation, 57 cycles/byte test 10 ( 2048 byte blocks, 256 bytes per update, 8 updates): 43008 cycles/operation, 21 cycles/byte test 11 ( 2048 byte blocks, 1024 bytes per update, 2 updates): 40176 cycles/operation, 19 cycles/byte test 12 ( 2048 byte blocks, 2048 bytes per update, 1 updates): 39888 cycles/operation, 19 cycles/byte test 13 ( 4096 byte blocks, 16 bytes per update, 256 updates): 194176 cycles/operation, 47 cycles/byte test 14 ( 4096 byte blocks, 256 bytes per update, 16 updates): 84096 cycles/operation, 20 cycles/byte test 15 ( 4096 byte blocks, 1024 bytes per update, 4 updates): 78336 cycles/operation, 19 cycles/byte test 16 ( 4096 byte blocks, 4096 bytes per update, 1 updates): 77120 cycles/operation, 18 cycles/byte test 17 ( 8192 byte blocks, 16 bytes per update, 512 updates): 403056 cycles/operation, 49 cycles/byte test 18 ( 8192 byte blocks, 256 bytes per update, 32 updates): 166112 cycles/operation, 20 cycles/byte test 19 ( 8192 byte blocks, 1024 bytes per update, 8 updates): 154768 cycles/operation, 18 cycles/byte test 20 ( 8192 byte blocks, 4096 bytes per update, 2 updates): 151904 cycles/operation, 18 cycles/byte test 21 ( 8192 byte blocks, 8192 bytes per update, 1 updates): 155456 cycles/operation, 18 cycles/byte testing speed of md5 test 0 ( 16 byte blocks, 16 bytes per update, 1 updates): 2208 cycles/operation, 138 cycles/byte test 1 ( 64 byte blocks, 16 bytes per update, 4 updates): 5008 cycles/operation, 78 cycles/byte test 2 ( 64 byte blocks, 64 bytes per update, 1 updates): 3600 cycles/operation, 56 cycles/byte test 3 ( 256 byte blocks, 16 bytes per update, 16 updates): 14080 cycles/operation, 55 cycles/byte test 4 ( 256 byte blocks, 64 bytes per update, 4 updates): 8560 cycles/operation, 33 cycles/byte test 5 ( 256 byte blocks, 256 bytes per update, 1 updates): 7040 cycles/operation, 27 cycles/byte test 6 ( 1024 byte blocks, 16 bytes per update, 64 updates): 50592 cycles/operation, 49 cycles/byte test 7 ( 1024 byte blocks, 256 bytes per update, 4 updates): 22736 cycles/operation, 22 cycles/byte test 8 ( 1024 byte blocks, 1024 bytes per update, 1 updates): 24960 cycles/operation, 24 cycles/byte test 9 ( 2048 byte blocks, 16 bytes per update, 128 updates): 99312 cycles/operation, 48 cycles/byte test 10 ( 2048 byte blocks, 256 bytes per update, 8 updates): 43520 cycles/operation, 21 cycles/byte test 11 ( 2048 byte blocks, 1024 bytes per update, 2 updates): 40704 cycles/operation, 19 cycles/byte test 12 ( 2048 byte blocks, 2048 bytes per update, 1 updates): 39552 cycles/operation, 19 cycles/byte test 13 ( 4096 byte blocks, 16 bytes per update, 256 updates): 196720 cycles/operation, 48 cycles/byte test 14 ( 4096 byte blocks, 256 bytes per update, 16 updates): 85152 cycles/operation, 20 cycles/byte test 15 ( 4096 byte blocks, 1024 bytes per update, 4 updates): 79408 cycles/operation, 19 cycles/byte test 16 ( 4096 byte blocks, 4096 bytes per update, 1 updates): 76816 cycles/operation, 18 cycles/byte test 17 ( 8192 byte blocks, 16 bytes per update, 512 updates): 391520 cycles/operation, 47 cycles/byte test 18 ( 8192 byte blocks, 256 bytes per update, 32 updates): 168464 cycles/operation, 20 cycles/byte test 19 ( 8192 byte blocks, 1024 bytes per update, 8 updates): 156912 cycles/operation, 19 cycles/byte test 20 ( 8192 byte blocks, 4096 bytes per update, 2 updates): 154016 cycles/operation, 18 cycles/byte test 21 ( 8192 byte blocks, 8192 bytes per update, 1 updates): 153856 cycles/operation, 18 cycles/byte We can ditch the sync hash code at some point if we feel that makes sense.

2010-05-19padata: Flush the padata queues activelySteffen Klassert
yield was used to wait until all references of the internal control structure in use are dropped before it is freed.

2010-05-19padata: Use a timer to handle remaining objects in the reorder queues Steffen Klassert
padata_get_next needs to check whether the next object that need serialization must be parallel processed by the local cpu. This check was wrong implemented and returned always true, so the try_again loop in padata_reorder was never taken. This can lead to object leaks in some rare cases due to a race that appears with the trylock in padata_reorder. The try_again loop was not a good idea after all, because a cpu could take that loop frequently, so we handle this with a timer instead. This patch adds a timer to handle the race that appears with the trylock. If cpu1 queues an object to the reorder queue while cpu2 holds the pd->lock but left the while loop in padata_reorder already, cpu2 can't care for this object and cpu1 exits because it can't get the lock. Usually the next cpu that takes the lock cares for this object too. We need the timer just if this object was the last one that arrives to the reorder queues. The timer function sends it out in this case. Signed-off-by: Steffen Klassert <steffen.klassert@secunet.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2010-04-30Staging: dt3155: fix 50Hz configurationH Hartley Sweeten
According to the header file, dt3155_io.h, the 50/60 Hz configuration is controlled by a bit in the I2C CSR2 register (bit 2). The function dt3155_init_isr actually reads the I2C CONFIG register into the global I2C_CSR union variable then modifies the bit. It then does a write to the I2C CONFIG register with the global I2C_CONFIG union variable which is not even set with a value anywhere in the driver. My guess is 50Hz operation doesn't even work as-is. Fix this by actually reading and writing the correct register with the correct value.

Latest SL811HS datasheet (Document 38-08008 Rev. *D) indicates that bit 6 (SL11H_INTMASK_RD) of the Interrupt Status Register together with bit 5 (SL11H_INTMASK_INSRMV) can be used to determine whether a device has been inserted or removed.

2010-04-30USB: ohci-at91: fix power management hangingPatrice Vilchez
A hanging has been detected in ohci-at91 while going in suspend to ram. This is due to asynchronous operations between ohci reset and ohci clocks shutdown. This patch adds the reading of the control register between the reset of the ohci and clocks stop. This "flush the writes" idea was taken from ohci-hcd.c file (ohci_shutdown() function).

2010-04-30USB: rename usb_buffer_alloc() and usb_buffer_free()Daniel Mack
For more clearance what the functions actually do, usb_buffer_alloc() is renamed to usb_alloc_coherent() usb_buffer_free() is renamed to usb_free_coherent() They should only be used in code which really needs DMA coherency.

2010-04-30USB: gadget: s3c-hsotg: Add missing unlockJulia Lawall
In an error handling case the lock is not unlocked. The return is converted to a goto, to share the unlock at the end of the function. A simplified version of the semantic patch that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r exists@ expression E1; identifier f; @@ f (...) { <+... * spin_lock_irqsave (E1,...); ... when != E1 * return ...; ...+> } // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2010-04-30USB: fix build on OMAPs if CONFIG_PM_RUNTIME is not setAnand Gadiyar
With patch as1329 (USB: convert to the runtime PM framework), we make USB_SUSPEND depend on PM_RUNTIME instead of CONFIG_PM. Also, CONFIG_USB_OTG selects CONFIG_USB_SUSPEND. If PM_RUNTIME is not enabled, and we try to enable USB_OTG, we will end up with CONFIG_USB_SUSPEND selected. This is due to a known bug with the select statement. This makes the build break on various OMAP configs (which have CONFIG_USB_OTG set by default, but do not yet have CONFIG_PM_RUNTIME enabled). Avoid this by changing the logic for CONFIG_USB_OTG from "select USB_SUSPEND" to "depends on USB_SUSPEND" Signed-off-by: Anand Gadiyar <gadiyar@ti.com> CC: Michal Marek <mmarek@suse.cz> CC: Tony Lindgren <tony@atomide.com> CC: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
