[RESEND PATCH 4/8] makedumpfile/ppc64: address change in _PAGE_PRESNT flag for PowerISA v3.0

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



PowerISA v3.0 CPUs expect _PAGE_PRESENT to be at 0x8000_0000_0000_0000
instead of 0x2 in radix mode. This is accomodated by changing the flag
_PAGE_PRESENT for 64-bit POWER server processors with kernel commit
849f86a6. This patch makes the corresponding change here.
