| * PM core: rename suspend and resume functionsAlan Stern2009-06-121-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as1241) renames a bunch of functions in the PM core. Rather than go through a boring list of name changes, suffice it to say that in the end we have a bunch of pairs of functions: device_resume_noirq dpm_resume_noirq device_resume dpm_resume device_complete dpm_complete device_suspend_noirq dpm_suspend_noirq device_suspend dpm_suspend device_prepare dpm_prepare in which device_X does the X operation on a single device and dpm_X invokes device_X for all devices in the dpm_list. In addition, the old dpm_power_up and device_resume_noirq have been combined into a single function (dpm_resume_noirq). Lastly, dpm_suspend_start and dpm_resume_end are the renamed versions of the former top-level device_suspend and device_resume routines.

| * PM: Rename device_power_down/up()Magnus Damm2009-06-121-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rename the functions performing "_noirq" dev_pm_ops operations from device_power_down() and device_power_up() to device_suspend_noirq() and device_resume_noirq(). The new function names are chosen to show that the functions are responsible for calling the _noirq() versions to finalize the suspend/resume operation. The current function names do not perform power down/up anymore so the names may be misleading. Global function renames: - device_power_down() -> device_suspend_noirq() - device_power_up() -> device_resume_noirq() Static function renames: - suspend_device_noirq() -> __device_suspend_noirq() - resume_device_noirq() -> __device_resume_noirq() Signed-off-by: Magnus Damm <damm@igel.co.jp> Acked-by: Greg Kroah-Hartman <gregkh@suse.de> Acked-by: Len Brown <lenb@kernel.org> Signed-off-by: Rafael J.

| | | | | | | | | | | | | | | | | | | | | | In this step, we do unify the copyright notes for both files cpu_32.c and cpu_64.c, making such files exactly the same.

Early printk device (uartlite in our case) was in TLB 2 and when kernel extract DTB it necessary to allocate at least one TLB at the end of memory. First free TLB was number two where was early printk. But checking mechanism (kernel/dts/pvr) was after extrahing but TLB 2 was different. This caused that kernel hung up. Moving early printk device to TLB 63 solve it and we don't protect it which means that we can use early_printk messages only for initial parts of kernel then we rewrite TLB 63. Reported-by: Edgar E.
