Since the addition of boot_cpu_init(), fixup_cpu_present_map() has been a
no-op.  That's because fixup_cpu_present_map() won't touch cpu_present_map if
it has any bits set, and boot_cpu_init() sets a bit.

So remove fixup_cpu_present_map().

A consequence of this (actually of the boot_cpu_init() change) is that the
architecture _must_ populate cpu_present_map itself (probably in
smp_prepare_cpus()).  fixup_cpu_present_map() won't do it any more.

If the architecture doesn't do this, it'll only bring up a single CPU.

The other side effect (though less serious) is that smp_prepare_boot_cpu() no
longer needs to mark the boot cpu in the online and present maps -
boot_cpu_init() does that for everyone (to make early printks work).

tlclk calls register_chrdev() and permits register_chrdev() to allocate the
major, but it promptly forgets what that major was.  So if there's no hardware
present you still get "telco_clock" appearing in /proc/devices and, I assume,
an oops reading /proc/devices if tlclk was a module.

Fix.

Mark, I'd suggest that that we not call register_chrdev() until _after_ we've
established that the hardware is present.

I discovered on oprofile hunting on a SMP platform that dentry lookups were
slowed down because d_hash_mask, d_hash_shift and dentry_hashtable were in
a cache line that contained inodes_stat.  So each time inodes_stats is
changed by a cpu, other cpus have to refill their cache line.

This patch moves some variables to the __read_mostly section, in order to
avoid false sharing.  RCU dentry lookups can go full speed.

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 :).

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.

dmi_scan_machine() tries to ioremap 0x10000 (64K) bytes, even though it only
looks at the first 32 bytes or so.  If the SMBIOS table is near the end of a
memory region, the ioremap() may fail when it shouldn't.

This is in the efi_enabled path, so it really only affects ia64 at the moment.

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.
