PM / Hibernate: Return error code when alloc_image_page() fails

2011-02-16T20:53:52Z

Currently we return 0 in swsusp_alloc() when alloc_image_page() fails. Fix that. Also remove unneeded "error" variable since the only useful value of error is -ENOMEM. [rjw: Fixed up the changelog and changed subject.] Signed-off-by: Stanislaw Gruszka Cc: stable@kernel.org Signed-off-by: Rafael J. Wysocki

workqueue, freezer: unify spelling of 'freeze' + 'able' to 'freezable'

2011-02-16T16:48:59Z

There are two spellings in use for 'freeze' + 'able' - 'freezable' and 'freezeable'. The former is the more prominent one. The latter is mostly used by workqueue and in a few other odd places. Unify the spelling to 'freezable'. Signed-off-by: Tejun Heo Reported-by: Alan Stern Acked-by: "Rafael J.

PM / ACPI: Move NVS saving and restoring code to drivers/acpi

2011-01-07T05:36:55Z

The saving of the ACPI NVS area during hibernation and suspend and restoring it during the subsequent resume is entirely specific to ACPI, so move it to drivers/acpi and drop the CONFIG_SUSPEND_NVS configuration option which is redundant. Signed-off-by: Rafael J. Wysocki Signed-off-by: Len Brown

PM: Fix oops in suspend/hibernate code related to failing ioremap()

2011-01-07T05:26:45Z

When ioremap() fails (which might happen for some reason), we nicely oops in suspend_nvs_save() due to NULL dereference by memcpy() in there. Fail gracefully instead. Signed-off-by: Jiri Slaby Signed-off-by: Rafael J. Wysocki Signed-off-by: Len Brown
