    cpumask: use work_on_cpu in acpi-cpufreq.c for drv_read and drv_write
    
    Impact: use new cpumask API to reduce stack usage
    
    Replace the saving of current->cpus_allowed and set_cpus_allowed_ptr() with
    a work_on_cpu function for drv_read() and drv_write().
    
    Basically converts do_drv_{read,write} into "work_on_cpu" functions that
    are now called by drv_read and drv_write.

Comment 4 Rafael J. Wysocki 2009-01-13 12:26:06 UTC

This commit has been reverted in mainline, so I think we can close this bug.

Please confirm that the current Linus' tree works for you.

Yep, the keyboard is back.
