[PATCH] Add hwcap2 bits for POWER9

[Carlos Eduardo Seo]

Hi

This patch adds the HWCAP2 masks for Power ISA 3.0 and VSX IEEE binary 
float 12-bit.

Michael Ellerman (in CC) will add the corresponding bit masks to the kernel.

Regards,

Subject: [PATCH] powerpc: Add hwcap2 bits for POWER9.

Added hwcap2 bit masks for Power ISA 3.0 and VSX IEEE binary float 128-bit
features.

2016-01-05  Carlos Eduardo Seo  <cseo@linux.vnet.ibm.com>

	* sysdeps/powerpc/bits/hwcap.h: Add PPC_FEATURE2_ARCH_3_00 and
	PPC_FEATURE2_HAS_IEEE128.
	* sysdeps/powerpc/dl-procinfo.c:
	(_dl_powerpc_cap_flags): Add corresponding names to new capabilities.
