From be70411f82cc7297b035c0fadaca57641b75bdc0 Mon Sep 17 00:00:00 2001 From: Marius Strobl Date: Sat, 2 Jan 2010 15:44:16 +0000 Subject: [PATCH] - Demapping unused kernel TLB slots has proven to work reliably so move the associated debugging under bootverbose. - Remove freebsd4_sigreturn(); given that FreeBSD 4 didn't supported sparc64 this only ever served as a transition aid prior to FreeBSD 5.0 and is unused by default since COMPAT_FREEBSD4 was removed from GENERIC in r143072 nearly 5 years ago. --- sys/sparc64/sparc64/machdep.c | 14 +++----------- 1 file changed, 3 insertions(+), 11 deletions(-) diff --git a/sys/sparc64/sparc64/machdep.c b/sys/sparc64/sparc64/machdep.c index 244928a81e37..06f6ebca8eb1 100644 --- a/sys/sparc64/sparc64/machdep.c +++ b/sys/sparc64/sparc64/machdep.c @@ -383,8 +383,9 @@ sparc64_init(caddr_t mdp, u_long o1, u_long o2, u_long o3, ofw_vec_t *vec) */ for (va = KERNBASE + (kernel_tlb_slots - 1) * PAGE_SIZE_4M; va >= roundup2(end, PAGE_SIZE_4M); va -= PAGE_SIZE_4M) { - printf("demapping unused kernel TLB slot (va %#lx - %#lx)\n", - va, va + PAGE_SIZE_4M - 1); + if (bootverbose) + printf("demapping unused kernel TLB slot " + "(va %#lx - %#lx)\n", va, va + PAGE_SIZE_4M - 1); stxa(TLB_DEMAP_VA(va) | TLB_DEMAP_PRIMARY | TLB_DEMAP_PAGE, ASI_DMMU_DEMAP, 0); stxa(TLB_DEMAP_VA(va) | TLB_DEMAP_PRIMARY | TLB_DEMAP_PAGE, @@ -660,15 +661,6 @@ sigreturn(struct thread *td, struct sigreturn_args *uap) return (EJUSTRETURN); } -#ifdef COMPAT_FREEBSD4 -int -freebsd4_sigreturn(struct thread *td, struct freebsd4_sigreturn_args *uap) -{ - - return sigreturn(td, (struct sigreturn_args *)uap); -} -#endif - /* * Construct a PCB from a trapframe.
