2011-02-13[SCSI] libata: separate error handler into usable componentsJames Bottomley
Right at the moment, the libata error handler is incredibly monolithic. This makes it impossible to use from composite drivers like libsas and ipr which have to handle error themselves in the first instance. The essence of the change is to split the monolithic error handler into two components: one which handles a queue of ata commands for processing and the other which handles the back end of readying a port. This allows the upper error handler fine grained control in calling libsas functions (and making sure they only get called for ATA commands whose lower errors have been fixed up).

2011-02-11ftrace: Fix memory leak with function graph and cpu hotplugSteven Rostedt
When the fuction graph tracer starts, it needs to make a special stack for each task to save the real return values of the tasks. All running tasks have this stack created, as well as any new tasks. On CPU hot plug, the new idle task will allocate a stack as well when init_idle() is called. The problem is that cpu hotplug does not create a new idle_task. Instead it uses the idle task that existed when the cpu went down. ftrace_graph_init_task() will add a new ret_stack to the task that is given to it. Because a clone will make the task have a stack of its parent it does not check if the task's ret_stack is already NULL or not. When the CPU hotplug code starts a CPU up again, it will allocate a new stack even though one already existed for it. The solution is to treat the idle_task specially. In fact, the function_graph code already does, just not at init_idle(). Instead of using the ftrace_graph_init_task() for the idle task, which that function expects the task to be a clone, have a separate ftrace_graph_init_idle_task(). Also, we will create a per_cpu ret_stack that is used by the idle task. When we call ftrace_graph_init_idle_task() it will check if the idle task's ret_stack is NULL, if it is, then it will assign it the per_cpu ret_stack.

2011-02-08ipsec: allow to align IPv4 AH on 32 bitsNicolas Dichtel
The Linux IPv4 AH stack aligns the AH header on a 64 bit boundary (like in IPv6). This is not RFC compliant (see RFC4302, Section 3.3.3.2.1), it should be aligned on 32 bits. For most of the authentication algorithms, the ICV size is 96 bits. The AH header alignment on 32 or 64 bits gives the same results. However for SHA-256-128 for instance, the wrong 64 bit alignment results in adding useless padding in IPv4 AH, which is forbidden by the RFC. To avoid breaking backward compatibility, we use a new flag (XFRM_STATE_ALIGN4) do change original behavior.

2011-02-07tracing/syscalls: Don't add events for unmapped syscallsIan Munsie
FTRACE_SYSCALLS would create events for each and every system call, even if it had failed to map the system call's name with it's number. This resulted in a number of events being created that would not behave as expected. This could happen, for example, on architectures who's symbol names are unusual and will not match the system call name. It could also happen with system calls which were mapped to sys_ni_syscall. This patch changes the default system call number in the metadata to -1. If the system call name from the metadata is not successfully mapped to a system call number during boot, than the event initialisation routine will now return an error, preventing the event from being created.

To fasten the process of firmware download, the chip allows disabling of the command complete event generation from host. In these cases, only few very essential commands would have the command complete events and hence the wait associated with them. So now the driver would wait for a command complete event, only when it comes across a wait event during firmware parsing.

2011-02-04ARM: mmci: add dmaengine-based DMA supportRussell King
Based on a patch from Linus Walleij. Add dmaengine based support for DMA to the MMCI driver, using the Primecell DMA engine interface. The changes over Linus' driver are: - rename txsize_threshold to dmasize_threshold, as this reflects the purpose more. - use 'mmci_dma_' as the function prefix rather than 'dma_mmci_'. - clean up requesting of dma channels. - don't release a single channel twice when it's shared between tx and rx. - get rid of 'dma_enable' bool - instead check whether the channel is NULL. - detect incomplete DMA at the end of a transfer. Some DMA controllers (eg, PL08x) are unable to be configured for scatter DMA and also listen to all four DMA request signals [BREQ,SREQ,LBREQ,LSREQ] from the MMCI. They can do one or other but not both. As MMCI uses LBREQ/LSREQ for the final burst/words, PL08x does not transfer the last few words. - map and unmap DMA buffers using the DMA engine struct device, not the MMCI struct device - the DMA engine is doing the DMA transfer, not us. - avoid double-unmapping of the DMA buffers on MMCI data errors. - don't check for negative values from the dmaengine tx submission function - Dan says this must never fail. - use new dmaengine helper functions rather than using the ugly function pointers directly. - allow DMA code to be fully optimized away using dma_inprogress() which is defined to constant 0 if DMA engine support is disabled. - request maximum segment size from the DMA engine struct device and set this appropriately. - removed checking of buffer alignment - the DMA engine should deal with its own restrictions on buffer alignment, not the individual DMA engine users. - removed setting DMAREQCTL - this confuses some DMA controllers as it causes LBREQ to be asserted for the last seven transfers, rather than six SREQ and one LSREQ. - removed burst setting - the DMA controller should not burst past the transfer size required to complete the DMA operation.

2011-02-03memory hotplug: Update phys_index to [start|end]_section_nrNathan Fontenot
Update the 'phys_index' property of a the memory_block struct to be called start_section_nr, and add a end_section_nr property. The data tracked here is the same but the updated naming is more in line with what is stored here, namely the first and last section number that the memory block spans. The names presented to userspace remain the same, phys_index for start_section_nr and end_phys_index for end_section_nr, to avoid breaking anything in userspace. This also updates the node sysfs code to be aware of the new capability for a memory block to contain multiple memory sections and be aware of the memory block structure name changes (start_section_nr). This requires an additional parameter to unregister_mem_sect_under_nodes so that we know which memory section of the memory block to unregister.
