* x86: fix visws and vsmp buildIngo Molnar2008-07-101-2/+2
| | | | | | | these two sub-architectures want PCI to be default-on, not default-off. Reported-by: Robert Richter <robert.richter@amd.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86: I/O APIC: Add a 64-bit variation of replace_pin_at_irq()Maciej W. Rozycki2008-07-101-1/+21
| | | | | | | | | | | | | When an interrupt is rerouted to a different I/O APIC pin the relevant entry of the irq_2_pin list should get updated accordingly so that operations are performed on the correct redirection entry. This is already done by the 32-bit variation of the code and here is a complementing 64-bit implementation. Should make someone's decision less tough when merging the two. ;) Signed-off-by: Maciej W.

* x86: traps_xx: shuffle headers and globalsAlexander van Heukelum2008-07-092-37/+33
| | | | | | | | | | | | | Reorder headers and collect globals in traps_32.c and traps_64.c Code size and data size are unaffected by the changes. Code itself is changed due to different ordering of data and bss. The bss segment changed size due to a change in the packing of the variables.
