[PATCH] enable CONFIG_RTAS_PROC by default

[PATCH] enable CONFIG_RTAS_PROC by default

[Paul Mackerras]

This patch enables CONFIG_RTAS_PROC by default on pSeries.  This will
preserve /proc/ppc64/rtas/rmo_buffer, which is needed by librtas.

This patch should go in 2.6.12.

shouldn't this move over to sysfs at some point, to some firmware
directory ?

Well, eventually maybe, but there are userspace programs using it, so
we can't remove the /proc interface for a while yet.

sure that's a given, the question is I guess first to start providing a
sysfs equivalent so that apps CAN start using the new thing, before even
thinking about the obsoletion of the old interface. That was more what I
was fishing for ...
