Brian Gerst noticed that I did a weird rename in the following commit:
b2502b418e ("x86/asm/entry: Untangle 'system_call' into two entry points: entry_SYSCALL_64 and entry_INT80_32")
which renamed __NR_ia32_syscall_max to __NR_entry_INT80_compat_max.
Now the original name was a misnomer, but the new one is a misnomer as well,
as all the 32-bit compat syscall entry points (sysenter, syscall) share the
system call table, not just the INT80 based one.
Rename it to __NR_syscall_compat_max.
