2013-04-17	e10c184 Browse files » memory commands: separate into one file per command ... Normally in commands we have one file per command which is named like the command itself. The memory commands are an exception to this. This patch changes this by separating the memory commands. This also has the effect that the memory commands can now be selected individually. Along the way we add some Kconfig help text for the commmands. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Sascha Hauer committed on 17 Apr 2013

'size' ranges from 0 to UINT[32\|64]_MAX + 1 which obviously leads to problems. 'end' on the other hand will never exceed UINT[32\|64]_MAX. Also this way we can express a iomem region covering the whole address space. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Sascha Hauer committed on 1 Jul 2012

2012-05-18	831be2e Browse files » lseek: return -1 instead of -errno ... The patch making errno a positive value has another bug: lseek was switched to return -errno instead of -1. This does not work since we can lseek we can address the whole 4G address space, have of which has a negative offset when interpreted as a signed integer. Let lseek return -1 on failure again instead. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Sascha Hauer committed on 18 May 2012
