x86: drop -fno-stack-protector annotations after pt_regs fixes

#

# On x86_32, register frame is passed verbatim on stack as struct

# pt_regs.  gcc considers the parameter to belong to the callee and

# with -fstack-protector it copies pt_regs to the callee's stack frame

# to put the structure after the stack canary causing changes made by

# the exception handlers to be lost.  Turn off stack protector for all

# files containing functions which take struct pt_regs from register

# frame.

#

# The proper way to fix this is to teach gcc that the argument belongs

# to the caller for these functions, oh well...
