| * sysfs: remove "last sysfs file:" line from the oops messagesGreg Kroah-Hartman2011-05-131-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On some arches (x86, sh, arm, unicore, powerpc) the oops message would print out the last sysfs file accessed. This was very useful in finding a number of sysfs and driver core bugs in the 2.5 and early 2.6 development days, but it has been a number of years since this file has actually helped in debugging anything that couldn't also be trivially determined from the stack traceback. So it's time to delete the line. This is good as we need all the space we can get for oops messages at times on consoles.

* | PM / UNICORE32: Use struct syscore_ops instead of sysdevs for PMRafael J. Wysocki2011-05-111-15/+8
|/ | | | | | | | | | | | | Make some UNICORE32 architecture's code use struct syscore_ops objects for power management instead of sysdev classes and sysdevs. This simplifies the code and reduces the kernel's memory footprint. It also is necessary for removing sysdevs from the kernel entirely in the future. Signed-off-by: Rafael J.
