The virtio console, which uses hvc, will get the ability to hot-unplug
ports. Export hvc_remove so that virtio_console can disassociate with
hvc.

This is nicer for modern R/O protection. And noone needs it non-const, so
constify the callers as well.

Make sure compiler won't do weird things with limits. E.g. fetching
them twice may return 2 different values after writable limits are
implemented.
I.e. either use newly added rlimit helpers or ACCESS_ONCE if not
applicable.

It turns out that we _need_ to ack the RSW (Reset Switch) interrupt.
The other interrupt sources checked (EXI, VI, DI, AI, DSP/ARAM) need
no explicit ack.
That would probably mean that the reset switch interrupt is an edge
interrupt.
Nah, it means that the RSW is a flip-flop.

Currently staprun fails at send_relocation_kernel(), this is because

Hi all,
Here are some patches that add systemtap support for ppc32 machines.
This is all pretty straightforward, though I didn't test it much,
only run few 'hello world' taps and decided that it's good enough. ;-)
I plan to test it more thoughtfully sometime next week, and fix missing

Windfarm SMU control is explicitly missing support for a second CPU pump in G5
PowerMacs. Such machines actually exist (specifically Quads with a second
pump), so this patch adds detection for it.

Hi,
As of now the kdump kernel base is fixed to be 32MB. The intention of
this patch is to modify that behaviour (for relocatable kernels)
* Regular kernel size may exceed 32MB, in this case we can't have kdump
kernelbase as 32MB.
* crashkernel=auto also assumes that kdump kernelbase as 32M

Maybe something like GAMECUBE_OR_WII instead? "COMMON" is so

Similarly, it is better to use a compatible value of something like:
