linux.git/kernel/power/nvs.c, branch master Linux kernel source tree PM / ACPI: Move NVS saving and restoring code to drivers/acpi 2011-01-07T05:36:55+00:00 Rafael J. Wysocki rjw@sisk.pl 2011-01-07T00:43:44+00:00 976513dbfc1547c7b1822566923058655f0c32fd 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.

PM: Fix oops in suspend/hibernate code related to failing ioremap() 2011-01-07T05:26:45+00:00 Jiri Slaby jslaby@suse.cz 2011-01-07T00:42:31+00:00 26fcaf60fe3861409eb4c455c5c0d0f00f599b08 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 <jslaby@suse.cz> Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Signed-off-by: Len Brown <len.brown@intel.com>
