* cpumask: use mm_cpumask() wrapper: x86Rusty Russell2009-09-23
| | | | | | | | | Makes code futureproof against the impending change to mm->cpu_vm_mask (to be a pointer). It's also a chance to use the new cpumask_ ops which take a pointer (the older ones are deprecated, but there's no hurry for arch code). Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

* x86: cleanup - eliminate numbers in LDT allocation codeCyrill Gorcunov2008-02-04
| | | | | | | | | | | | | | | | | | | This patch eliminates numbers in LDT allocation code trying to make it clear to understand from where these numbers come.

* x86: adjust/fix LDT handling for XenJan Beulich2008-01-30
| | | | | | | | | | | | | | | | | | | Based on patch from Jan Beulich <jbeulich@novell.com>. Don't rely on kmalloc(PAGE_SIZE) returning PAGE_SIZE aligned memory (Xen requires GDT *and* LDT to be page-aligned). Using the page allocator interface also removes the (albeit small) slab allocator overhead. The same change being done for 64-bits for consistency. Further, the Xen hypercall interface expects the LDT address to be virtual, not machine.
