Date: Wed, 12 Sep 2012 16:28:02 -0700 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org, stable@...r.kernel.org Cc: Greg KH <gregkh@...uxfoundation.org>, Will Deacon <will.deacon@....com>, Russell King <rmk+kernel@....linux.org.uk> Subject: [ 004/108] ARM: 7483/1: vfp: only advertise VFPv4 in hwcaps if CONFIG_VFPv3 is enabled From: Greg KH <gregkh@...uxfoundation.org> 3.5-stable review patch. If anyone has any objections, please let me know. ------------------ From: Will Deacon <will.deacon@....com> commit 3d9fb0038a9b02febb01efc79a4a5d97f1822a90 upstream. VFPv4 support depends on the VFPv3 context save/restore code, so only advertise support in the hwcaps if the kernel can actually handle it.
