Imre Deak	82c6f5a5b3	ARM: 6051/1: VFP: preserve the HW context when calling signal handlers ... From: Imre Deak <imre.deak@nokia.com> Signal handlers can use floating point, so prevent them to corrupt the main thread's VFP context. So far there were two signal stack frame formats defined based on the VFP implementation, but the user struct used for ptrace covers all posibilities, so use it for the signal stack too. Introduce also a new user struct for VFP exception registers. In this too fields not relevant to the current VFP architecture are ignored. Support to save / restore the exception registers was added by Will Deacon.

Catalin Marinas	3d1228ead6	[ARM] 5387/1: Add ptrace VFP support on ARM ... This patch adds ptrace support for setting and getting the VFP registers using PTRACE_SETVFPREGS and PTRACE_GETVFPREGS. The user_vfp structure defined in asm/user.h contains 32 double registers (to cover VFPv3 and Neon hardware) and the FPSCR register.
