    syscalls/core, syscalls/x86: Rename struct pt_regs-based sys_*() to __x64_sys_*() · d5a00528
    Dominik Brodowski authored
    This rename allows us to have a coherent syscall stub naming convention on
    64-bit x86 (0xffffffff prefix removed):
    
     810f0af0 t            kernel_waitid	# common (32/64) kernel helper
    
     <inline>            __do_sys_waitid	# inlined helper doing actual work
     810f0be0 t          __se_sys_waitid	# C func calling inlined helper
    
     <inline>     __do_compat_sys_waitid	# inlined helper doing actual work
     810f0d80 t   __se_compat_sys_waitid	# compat C func calling inlined helper
    
     810f2080 T         __x64_sys_waitid	# x64 64-bit-ptregs -> C stub
     810f20b0 T        __ia32_sys_waitid	# ia32 32-bit-ptregs -> C stub[*]
     810f2470 T __ia32_compat_sys_waitid	# ia32 32-bit-ptregs -> compat C stub
     810f2490 T  __x32_compat_sys_waitid	# x32 64-bit-ptregs -> compat C stub
    
        [*] This stub is unused, as the syscall table links
    	__ia32_compat_sys_waitid instead of __ia32_sys_waitid as we need
    	a compat variant here.
