Need to increment the version number because of the new PCI and sysfs
capabilities of the driver. People maintaining things for distros have
asked that I do this after interface or major functional changes.

Add full driver model support for the IPMI driver. It links in the proper
bus and device support.
It adds an "ipmi" driver interface that has each BMC discovered by the
driver (as a device). These BMCs appear in the devices/platform directory.
If there are multiple interfaces to the same BMC, the driver should
discover this and will only have one BMC entry. The BMC entry will have
pointers to each interface device that connects to it.
The device information (statistics and config information) has not yet been
ported over to the driver model from proc, that will come later.
This work was based on work by Yani Ioannou. I basically rewrote it using
that code as a guide, but he still deserves credit :).

Modify the PCI hanling code for the IPMI driver to use the new method of
tables and registering, and adds more generic PCI handling for IPMI.
Unfortunately, this required a rather large rework of the way the driver
did detection so it would be more event-driven.

Here's a patch that fixes EFI boot for x86 on 2.6.16-rc5-mm3. The
off-by-one is admittedly my fault, but the other two fix up the rest.

Almost all users of the table addresses from the EFI system table want
physical addresses. So rather than doing the pa->va->pa conversion, just keep
physical addresses in struct efi.
This fixes a DMI bug: the efi structure contained the physical SMBIOS address
on x86 but the virtual address on ia64, so dmi_scan_machine() used ioremap()
on a virtual address on ia64.
This is essentially the same as an earlier patch by Matt Tolentino:
http://marc.theaimsgroup.com/?l=linux-kernel&m=112130292316281&w=2
except that this changes all table addresses, not just ACPI addresses.
Matt's original patch was backed out because it caused MCAs on HP sx1000
systems. That problem is resolved by the ioremap() attribute checking added
for ia64.

Pass the size, not a pointer to the size, to efi_mem_attribute_range().
This function validates memory regions for the /dev/mem read/write/mmap paths.
The pointer allows arches to reduce the size of the range, but I think that's
unnecessary complexity. Simplifying it will let me use
efi_mem_attribute_range() to improve the ia64 ioremap() implementation.

- Move the core parser into dmi_scan.c. It can be useful for other
subsystems too.
- Differentiate between field doesn't exist and field is 0 or
unparseable. The first case is likely an old BIOS with broken ACPI,
the later is likely a slightly buggy BIOS where someone forget to
edit the date. Don't blacklist in the later case.

cpufreq are the only remaining bit to be solved for me to have a modpost
clean build for sparc64 - so I took one more look at it.
changelog entry:
Fix section mismatch warnings in cpufreq:
WARNING: drivers/cpufreq/cpufreq_stats.o - Section mismatch: reference to .init.text: from .data between 'cpufreq_stat_cpu_notifier' (at offset 0xa8) and 'notifier_policy_block'
WARNING: drivers/cpufreq/cpufreq_stats.o - Section mismatch: reference to .init.text: from .exit.text after 'cleanup_module' (at offset 0x30)
The culprint is the function: cpufreq_stat_cpu_callback
It is marked __cpuinit which get's redefined to __init in case
HOTPLUG_CPU is not enabled as per. init.h:
#ifdef CONFIG_HOTPLUG_CPU
#define __cpuinit
#else
#define __cpuinit __init
#endif
$> grep HOTPLUG .config
CONFIG_HOTPLUG=y
But cpufreq_stat_cpu_callback() is used in:
__exit cpufreq_stats_exit()
static struct notifier_block cpufreq_stat_cpu_notifier
cpufreq_stat_cpu_notifier is again used in:
__init cpufreq_stats_init()
__exit cpufreq_stats_exit()
So in both cases used from both __init and __exit context.
Only solution seems to drop __cpuinit tag.

This patch adds proper logic to cpufreq driver in order to handle
CPU Hotplug.
When CPUs go on/offline, the affected CPUs data, cpufreq_policy->cpus,
is not updated properly. This causes sysfs directories and symlinks to
be in an incorrect state after few CPU on/offlines.

This patch causes the network interface to respond to P_Key change
events correctly. As a result, you'll see a child interface in the
"RUNNING" state (netif_carrier_on()) only when the corresponding P_Key
is configured by the SM. When SM removes a P_Key, the "RUNNING" state
will be disabled for the corresponding network interface. To
implement this, I added IB_EVENT_PKEY_CHANGE event handling. To
prevent flushing the device before the device is open by the "delay
open" mechanism, I added an additional device flag called
IPOIB_FLAG_INITIALIZED.
This also prevents the child network interface from trying to join to
multicast groups until the PKEY is configured. We used to get error
messages like:
ib0.f2f2: couldn't attach QP to multicast group ff12:401b:f2f2:0:0:0:ffff:ffff
in this case. To fix this, I just check IPOIB_FLAG_OPER_UP flag in
ipoib_set_mcast_list().

If the call to mthca_MODIFY_QP() failed, then mthca_modify_qp() would
still do some things it shouldn't, such as store away attributes for

With the current IPoIB driver, the status of network interfaces stays
"RUNNING" even if the link goes down (for example because a cable is
unplugged). Fix this by flushing the IPoIB interface when the link
goes down.

mthca_alloc_sqp() by mthca_set_qp_size() need to set qp->transport
before calling mthca_set_qp_size(), since the value is used there.

When setting the shared receive queue (SRQ) watermark in a modify SRQ
operation, make sure that the supplied value is not larger than the
full size of the SRQ.

Guarantee the calculated work queue entry size does not exceed the max
allowable WQE size when creating an SRQ. This is a problem with Arbel
in Tavor-compatibility mode because the current WQE size computation
method rounds up to next power of 2.

Add a check that the modify QP parameters sgid_index and path_mtu are
valid, since they might come from userspace.

Since the SCSI midlayer is moving towards entirely getting rid of
commands with use_sg == 0, we should treat this case as an exception.
Therefore, change the IB SRP initiator to create a fake scatterlist
for these commands with sg_init_one(). This simplifies the flow of
DMA mapping and unmapping, since SRP can just use dma_map_sg() and
dma_unmap_sg() unconditionally, rather than having to choose between
the dma_{map,unmap}_sg() and dma_{map,unmap}_single() variants.
