        src/sys/arch/aarch64/aarch64: vectors.S

Log Message:
Create a buffer space of 512 bytes before the trapframe.

dtrace fbt needs enough space to emulate an

        stp     x29, x30, [sp,#-FRAMESIZE]!

instruction in a function prologue.  In the aarch64 instruction
encoding, FRAMESIZE can be as large as 512 bytes, so reserve this
much space when KDTRACE_HOOKS is enabled.
