[PATCH][TOOLS] libxc: mmap fixes for BSD
Hi!
On BSD, mmap()ing files works on on-disk files but not on
pseudo filesystems like kernfs or procfs.
Therefore, attached patch mmap()s anonymous memory.
Linux equivalents are sysfs and procfs to above BSD''s pseudo-filesystems.
On Linux, mmap is implemented for sysfs but it is questionable to me
how write operations work since (most) files in sysfs have
static content. So this patch

3.1.1 RC4?
Keir,
I noticed that a Shadow patch went into the 3.1.1 staging tree today.
Does this mean that we should expect a 4th release candidate before the
3.1.1 release tag is official?
If so - how much testing time are you going to give that release
candidate before deciding whether a release tag, or another RC round is
appropriate?

[PATCH][ELF] Correct space calculation for symtab when BSD_SYMTAB=yes
Hi!
If there is a string table for section headers, it also gets loaded.
Therefore take it into account in size calculation for kernel symtab.
Also there is no need to call elf_set_verbose() a second time
after elf_init() (First call happens within elf_init()).

RFC: MCA/MCE concept
Hello!
The current MCA/MCE support in Xen is that it dumps the error and panics.
In the following concept I propose here, there are two places where Xen has to
react on.
I) Xen receives a MCE from the CPU and
II) Xen receives Dom0 instructions via Hypercall
The term "self-healing" below is used in the sense of using the most propriate
technique(s) to handle an error such as MPR

Xen HVM cpuid problem
Hi Keir,
For HVM guests, all cpuid Fn''s going through domain_cpuid()
iterate over the loop and then return 0 for all four registers.
Guests OS''s and cpuid tools in HVM which query for
cpuid Fn 0000.0000 %eax and 8000.0000 %eax, see the value 0 and think,
Xen emulates oldish 386/486 CPUs.
This leads to strange boot failures, "your CPU does not support long mode"

Does xentrace write into buffers by default?
Hello,
I have a question about the way Xentrace takes a trace.
In previous versions of Xen, I took a trace by setting the size of buffers,
activating them and writing the information into a file (optional).
setsize 20
tbctl 1
xentrace /tmp/xentrace.dat
Now I''m using xen-unstable and I see that setsize is already integrated in
xentrace command.
My question is: does start/stop buffer is

[PATCH] small mca cleanup
Hi!
The MCG_CAP MSR never returns a negative count of available
error-reporting banks. Thus make nr_mce_banks unsigned.
While here, do some other minor cleanups.
