Allocating PDA and GDT at boot is a pain. Using simple per-cpu
variables adds happiness (although we need the GDT page-aligned for
Xen, see later).
Finally, we can simply call it "cpu_gdt" rather than enduring the
superfluous and unnecessarily redundant tautology of "cpu_gdt_table".

The comment above this function has never been true in mainline:
talking to Jeremy it's from previous patch churn. What setup_pda
actually does is to write the segment entry for boot_pda into the
boot_gdt_table. Ideally, this would be a static initialization, but
because the addresses are split o

Now we have an explicit per-cpu GDT variable, we don't need to keep
the descriptors around to use them to find the GDT. Also remove the
cpu_pda() accessor: it's just a per-cpu variable.

Xen wants page-aligned GDT (and PDA must not cross a page-boundary,
but that doesn't happen at the moment since it's so close to start of
page). Let's allow page-alignment in general for per-cpu data.
Because larger alignments can use more room, we increase the max
per-cpu memory to 64k rather th
Xen wants a dedicated page for the GDT. I believe VMI likes it too.
lguest, KVM and native don't care.
Simple transformation to page-aligned "struct gdt_page".

your config works fine here too
Currently x86 (similar to x84-64) has a special per-cpu structure
called "i386_pda" which can be easily and efficiently referenced via
the %fs register. An ELF section is more flexible than a structure,
allowing any piece of code to use this area. Indeed, such a section
already exists: the per-cp

Use sys_reboot() syscall with either LINUX_REBOOT_CMD_HALT or
LINUX_REBOOT_CMD_POWER_OFF.

The airo driver tries to avoid excessive latencies when issuing commands
to the card by calling schedule() after several retries. But
issuecommand() can be run from an interrupt handler. The function is
careful enough to check with in_atomic() if it is safe to call schedule().
This check breaks whe

Hi,
i'm happy to report that i've been able to boot my ibook without any error,
using Ken Moffat's .config (thanks again Ken!) as a base.
I'm putting the prominent part here for completeness.
I still have no idea what caused these errors, but at least i'll try to find
what was compiled with the f
