The "reboot" function fails on Linux/Alpha. The problem is due to type
promotion rules. The constant 0xfee1dead exceeds the range for (int), and
is promoted to (unsigned int). The INLINE_SYSCALL passes (long), so the
value is zero-extended to 64 bits and passed in a register. The kernel
code specifies (int), and expects sign-extension to 64 bits. The magic
match fails. The following corrects this for me. (I think that the large
constants for the "howto" parameter are handled by the prototype, although
I haven't checked for this.)
