Subject: [PATCH] Make tlb_remove_tlb_entry take ptep
Date: Wed, 17 Jul 2002 22:23:42 -0700 [thread overview]
Message-ID: <20020718052342.GE1204@krispykreme> (raw)
Hi,
It seems only ppc32 and ppc64 use tlb_remove_tlb_entry. On ppc64 we need
a pointer to the pte so we can change some of the pte bits.
Paul has some nice patches to clean up tlb teardown, but the following
patch should allow ppc32 and ppc64 to work in the meantime.
Anton
