[PATCH] ARM: vfp: only advertise VFPv4 in hwcaps if CONFIG_VFPv3 is enabled

From: Will Deacon <hidden>
Date: 2012-07-26 12:54:33
Subsystem: arm port, arm/vfp support, the rest · Maintainers: Russell King, Linus Torvalds

VFPv4 support depends on the VFPv3 context save/restore code, so only
advertise support in the hwcaps if the kernel can actually handle it.

Pretty boring, but I guess a candidate for -stable.
