[PATCH 1/8] Remove cpu_gdt_table: use boot_gdt_table until migration to per-cpu

2007-03-06 Thread Rusty Russell
Linux uses three GDTs to boot: the boot_gdt_table, which contains only the __BOOT_CS and __BOOT_DS entries is used first up, before kernel is mapped at PAGE_OFFSET. Then we transition to cpu_gdt_table during boot, and finally we allocate a per-cpu GDT and switch to that. We can simplify this by

[PATCH 3/8] Use per-cpu variables for GDT, PDA

2007-03-06 Thread Rusty Russell
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. Signed-off-by:

[PATCH 4/8] Cleanup setup_pda

2007-03-06 Thread Rusty Russell
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
