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 <cseo@linux.vnet.ibm.com> * 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.
