| * | x86-64, reboot: Be more paranoid in 64-bit reboot=bios | H. Peter Anvin | 2012-06-21 | 1 | -2/+6 |
| | | | | | | | | | | | | | Be a bit more paranoid in the transition back to 16-bit mode. In particular, in case the kernel is residing above the 4 GiB mark, switch to the trampoline GDT, and make the jump after turning off paging a far jump. In theory, none of this should matter, but it is exactly the kind of things that broken SMM or virtualization software could trip up on. Signed-off-by: H.

| * | x86-64, reboot: Allow reboot=bios and reboot-cpu override on x86-64 | H. Peter Anvin | 2012-06-17 | 1 | -0/+152 |
| With the revamped realmode trampoline code, it is trivial to extend support for reboot=bios to x86-64. Furthermore, while we are at it, remove the restriction that only we can only override the reboot CPU on 32 bits. Signed-off-by: H.
