* | powerpc/book3e: Add generic 64-bit idle powersave support | Benjamin Herrenschmidt | 2010-07-14 | 1 | -0/+86 |
We use a similar technique to ppc32: We set a thread local flag to indicate that we are about to enter or have entered the stop state, and have fixup code in the async interrupt entry code that reacts to this flag to make us return to a different location (sets NIP to LINK in our case).
