Subject: Allow paravirt backend to choose kernel PMD sharing
Normally when running in PAE mode, the 4th PMD maps the kernel address
space, which can be shared among all processes (since they all need
the same kernel mappings).
Xen, ho

OK. I won't specifically redo it on top of your patches, but I'll
rework it to remove the inline function and add the if() statement. Do
you want an incremental update or a co

You're too kind. wli's comment on the first version of this patch was
something along the lines of "this patch causes a surprising amount of
damage for what little it achieves".

Yeah, it's just a simple name change, so it will either compile or not.

Needed a bit of updating for Andi's recently-merged

Most of asm-i386/bugs.h is code which should be in a C file, so put it there.

Some versions of libc can't deal with a VDSO which doesn't have its
ELF headers matching its mapped address. COMPAT_VDSO maps the VDSO at
a specific system-wide fixed address. Previously this was all done at
build time, on the grounds that the fixed VDSO address is always at
the top of the addres
identify_cpu() is used to identify both the boot CPU and secondary
CPUs, but it performs some actions which only apply to the boot CPU.
Those functions are therefore really __init functions, but because
they're called by identify_cpu(), they must be marked __cpuinit.
This patch splits identify_cpu
Now that relocation of the VDSO for COMPAT_VDSO users is done at
runtime rather than compile time, it is possible to enable/disable
compat mode at runtime.
This patch allows you to enable COMPAT_VDSO mode with "vdso=2" on the
kernel command line, or via sysctl. (Switching on a running system

Hi Andi,
Four patches:
- clean up asm/bugs.h, by moving all the C code into its own C file
- split identify_cpu() into boot and secondary variants, so that
boot-time setup functions can be marked __init
- repost of the COMPAT_VDSO patches with a bit more robustness from
unknown DT_tags, a
