So the SYSENTER instruction is pretty quirky and it has different behavior depending on bitness and CPU maker. Yet we create a false sense of coherency by naming it 'ia32_sysenter_target' in both of the cases. Split the name into its two uses: ia32_sysenter_target (32) -> entry_SYSENTER_32 ia32_sysenter_target (64) -> entry_SYSENTER_compat As per the generic naming scheme for x86 system call entry points: entry_MNEMONIC_qualifier where 'qualifier' is one of _32, _64 or _compat.
