One of them is really more a workaround for a host bug than a UML bug
fix, but it does robustify the early boot checks a bit, and makes UML
boot on current FC6, so it's worth going in 2.6.22.
The other is a trivial error return fix in the ubd driver.

Make the PTRACE_SYSEMU checking more robust. It will make sure that
system call numbers are reported correctly. If there is a problem, it
will disable PTRACE_SYSEMU use and use PTRACE_SYSCALL instead.

I tried that - Andi didn't like it. My current thinking is to pull the
cmpxchg stuff out of

Allocate file 1 in chunk A.
Grow file 1.
Chunk A fills up.
Allocate continuation inode for file 1 in chunk B.
Chunk A gets some free space.
Chunk B fills up.
Pick chunk A for allocating next

Yes - then system.h may be included twice but that's ok.
I tried that - Andi didn't like it. My current thinking is to pull the
cmpxchg stuff out of
of code afterwards.
The physical memory remapping stuff is gone, as it is unused.
flush_tlb_page is inlined.

When doing a full address space flush, only look at areas covered by a VMA.

It turns out that the message complaining about a lack of tmpfs space
on the host can be misunderstood as referring to the UML.

Patches 2 and 3 are more work on making tlb flushing more efficient.
Patches 1 and 4 are trivial.
Patch 5 fixes a problem with virtualized time not being fully virtual
with the kernel's current timekeeping.
