Subject: Regarding DSISR value of 0xa410
Date: Wed, 30 Sep 2015 16:51:21 +0530 [thread overview]
Message-ID: <560BC5B1.1050609@linux.vnet.ibm.com> (raw)
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
