[PATCH 1/4] arm_elf_read_implies_exec(): remove unused argument

[Nicolas Pitre]

The first argument to elf_read_implies_exec() is either the actual
header structure or a pointer to that structure whether one looks
at fs/binfmt_elf.c or fs/binfmt_elf_fdpic.c. This ought to be fixed
of course, but in the mean time let's sidestep the issue by removing
that first argument from arm_elf_read_implies_exec() as it is unused
anyway.
