Hey Ben/Michael,

Why does 0xa410 value of DSISR called weird here ? What does this
signify ? Just wondering if we can replace it with a meaningful
macro instead.

arch/powerpc/kernel/exceptions-64s.S

/*
 * Hash table stuff
 */
        .align  7
do_hash_page:
        std     r3,_DAR(r1)
        std     r4,_DSISR(r1)

        andis.  r0,r4,0xa410            /* weird error? */

Regards
Anshuman
