From 3c13f28c8eac1e5a883d1b3801314430a094fc99 Mon Sep 17 00:00:00 2001 From: Carlos Eduardo Seo Date: Wed, 19 Aug 2015 01:42:55 -0300 Subject: [PATCH] powerpc: Sync hwcap.h with kernel Linux commit b4b56f9ecab40f3b4ef53e130c9f6663be491894 introduced a new HWCAP2 bit to indicate that the kernel now aborts a memory transaction when a syscall is made. This patch adds that bit to sysdeps/powerpc/bits/hwcap.h. 2015-08-26 Carlos Eduardo Seo * sysdeps/powerpc/bits/hwcap.h: Add PPC_FEATURE2_HTM_NOSC. * sysdeps/powerpc/dl-procinfo.c: (_dl_powerpc_cap_flags): Added descriptor for this hwcap feature so it shows when LD_SHOW_AUXV=1. --- ChangeLog | 7 +++++++ sysdeps/powerpc/bits/hwcap.h | 2 ++ sysdeps/powerpc/dl-procinfo.c | 2 +- 3 files changed, 10 insertions(+), 1 deletion(-) diff --git a/ChangeLog b/ChangeLog index 89e51f690e..91dcd52fcc 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,10 @@ +2015-08-26 Carlos Eduardo Seo + + * sysdeps/powerpc/bits/hwcap.h: Add PPC_FEATURE2_HTM_NOSC. + * sysdeps/powerpc/dl-procinfo.c: + (_dl_powerpc_cap_flags): Added descriptor for this hwcap + feature so it shows when LD_SHOW_AUXV=1. + 2015-08-26 Paul E.
