2014-04-05nfs: pass string length to pr_notice message about readdir loopsJeff Layton1-4/+3
There is no guarantee that the strings in the nfs_cache_array will be NULL-terminated. In the event that we end up hitting a readdir loop, we need to ensure that we pass the warning message the length of the string.

2014-04-05ARC: [nsimosci] Change .dts to use generic 8250 UARTMischa Jonker1-4/+3
The Synopsys APB DW UART has a couple of special features that are not in the System C model. In 3.8, the 8250_dw driver didn't really use these features, but from 3.9 onwards, the 8250_dw driver has become incompatible with our model.

2014-04-04Fix index regression in nand_read_subpageRon1-3/+2
Commit 7351d3a5dbf42ba3299af71db3296be447bc1516 added an index variable as part of fixing checkpatch warnings, presumably as a tool to make some long lines shorter, however it only set that index in the case of there being no gaps in eccpos for the fragment being read. Which means the later step of filling ecccode from oob_poi will use the wrong indexing into eccpos in that case. This patch restores the behaviour that existed prior to that change.
