2011-08-25dmaengine/amba-pl08x: Add prep_single_byte_llis() routineViresh Kumar
Code for creating single byte llis is present at several places. Create a routine to avoid code redundancy. Also, we don't need one lli per single byte transfer, we can have single lli to do all single byte transfer.

2011-08-25dmaengine/amba-pl08x: max_bytes_per_lli is TRANSFER_SIZE * src_width (not ↵Viresh Kumar
MIN(width)) max_bytes_per_lli = bd.srcbus.buswidth * PL080_CONTROL_TRANSFER_SIZE_MASK; This is confirmed by ARM support guys. Below is summary of mail exchange with them: [Viresh] What is the total data to be transferred in case source and destination bus widths are different. Suppose, source bus width is 2 bytes and destination is 4 bytes. Now in order to transfer 80 bytes, what should be value of TransferSize field in control reg: 40? or 20?. [David from ARM] The value that is programmed into the TransferSize field should be the number of <SourceWidth> transfers needed to achieve the required data transfer. So, to transfer 80 bytes, with a Source Width of 2, the TransferSize field = should be programmed with: Total transfer size ------------------- = 40 <source width> [Viresh] Will this change if source is 4 bytes and dest is 2? [David] Yes - the calculation then becomes: Total transfer size ------------------- =20 <source width> Also, max_bytes_per_lli must be calculated after fixing src and dest widths not before that. So move this code to the correct place. This patch also removes max_bytes_per_lli from earlier print message, as till that point max_bytes_per_lli is unknown.

2011-08-25dmaengine/amba-pl08x: Get rid of pl08x_pre_boundary()Viresh Kumar
Pl080 Manual says: "Bursts do not cross the 1KB address boundary" We can program the controller to cross 1 KB boundary on a burst and controller can take care of this boundary condition by itself. Following is the discussion with ARM Technical Support Guys (David): [Viresh] Manual says: "Bursts do not cross the 1KB address boundary" What does that actually mean? As, Maximum size transferable with a single LLI is 4095 * 4 =16380 ~ 16KB. So, if we don't have src/dest address aligned to burst size, we can't use this big of an LLI. [David] There is a difference between bursts describing the total data transferred by the DMA controller and AHB bursts. Bursts described by the programmable parameters in the PL080 have no direct connection with the bursts that are seen on the AHB bus. The statement that "Bursts do not cross the 1KB address boundary" in the TRM is referring to AHB bursts, where this limitation is a requirement of the AHB spec. You can still issue bursts within the PL080 that are in excess of 1KB. The PL080 will make sure that its bursts are broken down into legal AHB bursts which will be formatted to ensure that no AHB burst crosses a 1KB boundary. Based on above discussion, this patch removes all code related to 1 KB boundary as we are not required to handle this in driver.

2011-08-25dmaengine/amba-pl08x: Schedule tasklet in case of error interruptViresh Kumar
Currently, if error interrupt occurs, nothing is done in interrupt handler (just clearing the interrupts). We must somehow indicate this to the user that DMA is over, due to ERR interrupt or TC interrupt. So, this patch just schedules existing tasklet, with a print showing error interrupt has occurred on which channels.

2011-08-07net: Compute protocol sequence numbers and fragment IDs using MD5.David S. Miller
Computers have become a lot faster since we compromised on the partial MD4 hash which we use currently for performance reasons. MD5 is a much safer choice, and is inline with both RFC1948 and other ISS generators (OpenBSD, Solaris, etc.) Furthermore, only having 24-bits of the sequence number be truly unpredictable is a very serious limitation. So the periodic regeneration and 8-bit counter have been removed. We compute and use a full 32-bit sequence number. For ipv6, DCCP was found to use a 32-bit truncated initial sequence number (it needs 43-bits) and that is fixed here as well.

2011-08-05PM / Runtime: Allow _put_sync() from interrupts-disabled contextKevin Hilman
Currently the use of pm_runtime_put_sync() is not safe from interrupts-disabled context because rpm_idle() will release the spinlock and enable interrupts for the idle callbacks. This enables interrupts during a time where interrupts were expected to be disabled, and can have strange side effects on drivers that expected interrupts to be disabled. This is not a bug since the documentation clearly states that only _put_sync_suspend() is safe in IRQ-safe mode. However, pm_runtime_put_sync() could be made safe when in IRQ-safe mode by releasing the spinlock but not re-enabling interrupts, which is what this patch aims to do. Problem was found when using some buggy drivers that set pm_runtime_irq_safe() and used _put_sync() in interrupts-disabled context.
