[uml-devel] [PATCH 5/9] UML - Remove duplicated exports

Al Viro spotted a bunch of duplicated exports - this removes them. Signed-off-by: Jeff Dike <[EMAIL PROTECTED]> Index: linux-2.6.13-rc6/arch/um/kernel/ksyms.c === --- linux-2.6.13-rc6.orig/arch/um/kernel/ksyms.c2005-08-15 12

[uml-devel] [PATCH 8/9] UML - Merge duplicated page table code

There is a lot of code which is duplicated between the 2 and 3 level implementation, with the only difference that the 3-level implementation is a bit more generalized (instead of accessing directly pte_t.pte, it uses the appropriate access macros). So this code is joined together. As obvious, a

[uml-devel] [PATCH 4/9] UML - Mark SMP on UML/x86_64 as broken

Noticed by Al Viro - SMP on x86_64 is fundamentally broken due to UML's reuse of the host arch's percpu stuff. This is OK on x86, but the x86_64 pda stuff just won't work for UML. Signed-off-by: Jeff Dike <[EMAIL PROTECTED]> Index: linux-2.6.13-rc6/arch/um/Kconfig ===

[uml-devel] [PATCH 7/9] UML - TLB operation batching

This adds VM op batching to skas0. Rather than having a context switch to and from the userspace stub for each address space change, we write a number of operations to the stub data page and invoke a different stub which loops over them and executes them all in one go. The operations are stored as
