[PATCH] mmconfig: Fix x86_64 ioremap base_address
Current mmconfig has some problems of remapped range.
a) In the case of broken MCFG tables on Asus etc., we need to remap 256M
range, but currently only remap 1M.
b) The base address always corresponds to bus number 0, but currently we
are assuming it corresponds to start bus number.
This patch fixes the above problems.
(akpm: Arjan suggests that if the MCFG table is broken we just shouldn't use
it, rather than try to work around things).

[PATCH] i386: Convert i386 PDA code to use %fs
Convert the PDA code to use %fs rather than %gs as the segment for
per-processor data. This is because some processors show a small but
measurable performance gain for reloading a NULL segment selector (as %fs
generally is in user-space) versus a non-NULL one (as %gs generally is).
On modern processors the difference is very small, perhaps undetectable.
Some old AMD "K6 3D+" processors are noticably slower when %fs is used
rather than %gs; I have no idea why this might be, but I think they're
sufficiently rare that it doesn't matter much.
This patch also fixes the math emulator, which had not been adjusted to
match the changed struct pt_regs.

[PATCH] x86-64: x86_64-make-the-numa-hash-function-nodemap-allocation fix fix
- Removed an extraneous debug message from allocate_cachealigned_map
- Changed extract_lsb_from_nodes to return 63 for the case where there was
only one memory node. The prevents the creation of the dynamic hashmap.
- Changed extract_lsb_from_nodes to use only the starting memory address of
a node. On an ES7000, our nodes overlap the starting and ending address,
meaning, that we see nodes like
00000 - 10000
10000 - 20000
But other systems have nodes whose start and end addresses do not overlap.
For example:
00000 - 0FFFF
10000 - 1FFFF
In this case, using the ending address will result in an LSB much lower
than what is possible. In this case an LSB of 1 when in reality it should
be 16.

This patch has the nice side effect in that it allows the hash map to grow

[PATCH] mark struct inode_operations const 3
Many struct inode_operations in the kernel can be "const". Marking them const
moves these to the .rodata section, which avoids false sharing with potential

[PATCH] remove broken video drivers
Remove some video drivers that:
- had already been marked as BROKEN in 2.6.0 three years ago and
- are still marked as BROKEN.
These are the following drivers:
- FB_CYBER
- FB_VIRGE
- FB_RETINAZ3
- FB_SUN3
Drivers that had been marked as BROKEN for such a long time seem to be
unlikely to be revived in the forseeable future.
But if anyone wants to ever revive any of these drivers, the code is
still present in the older kernel releases.

[PATCH] hotplug: Allow modules to use the cpu hotplug notifiers even if !CONFIG_HOTPLUG_CPU
The following patchset allows a host with running virtual machines to be
suspended and, on at least a subset of the machines tested, resumed. Note
that this is orthogonal to suspending and resuming an individual guest to a
file.
A side effect of implementing suspend/resume is that cpu hotplug is now
supported. This should please the owners of big iron.
This patch:
KVM wants the cpu hotplug notifications, both for cpu hotplug itself, but more
commonly for host suspend/resume.
In order to avoid extensive #ifdefs, provide stubs when CONFIG_CPU_HOTPLUG is
not defined.
In all, we have four cases:
- UP: register and unregister stubbed out
- SMP+hotplug: full register and unregister
- SMP, no hotplug, core: register as __init, unregister stubbed
(cpus are brought up during core initialization)
- SMP, no hotplug, module: register and unregister stubbed out
(cpus cannot be brought up during module lifetime)
