a0f62ac636 [PATCH] 2TB files: add blkcnt_t
Add blkcnt_t as the type of inode.i_blocks.  This enables you to make the size
of blkcnt_t either 4 bytes or 8 bytes on 32 bits architecture with CONFIG_LSF.

- CONFIG_LSF
  Add new configuration parameter.
- blkcnt_t
  On h8300, i386, mips, powerpc, s390 and sh that define sector_t,
  blkcnt_t is defined as u64 if CONFIG_LSF is enabled; otherwise it is
  defined as unsigned long.
  On other architectures, it is defined as unsigned long.
- inode.i_blocks
  Change the type from sector_t to blkcnt_t.

abcb6c9fd1 [PATCH] 2TB files: st_blocks is invalid when calling stat64
This patch series fixes the following problems on 32 bits architecture.

o stat64 returns the lower 32 bits of blocks, although userland st_blocks
  has 64 bits, because i_blocks has only 32 bits.  The ioctl with FIOQSIZE has
  the same problem.

o As Dave Kleikamp said, making >2TB file on JFS results in writing an
  invalid block number to disk inode.  The cause is the same as above too.

o In generic quota code dquot_transfer(), the file usage is calculated from
  i_blocks via inode_get_bytes().  If the file is over 2TB, the change of
  usage is less than expected.  The cause is the same as above too.

o As Trond Myklebust said, statfs64's entries related to blocks are invalid
  on statfs64 for a network filesystem which has more than 2^32-1 blocks with
  CONFIG_LBD disabled.  [PATCH 3/3]

We made patches to fix problems that occur when handling a large filesystem
and a large file.  It was discussed on the mails titled "stat64 for over 2TB
file returned invalid st_blocks".

9a98e2f732 [PATCH] remove fixup_cpu_present_map()
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).

222b9f933a [PATCH] tlclk: fix handling of device major
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.

50c812b2b9 [PATCH] ipmi: add full sysfs support
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 :).

23dd842c00 [PATCH] EFI fixes
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.

b2c99e3c70 [PATCH] EFI: keep physical table addresses in efi structure
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.

27d8e3d15b [PATCH] DMI: only ioremap stuff we actually need
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.

e9b0a07121 [PATCH] ia64: ioremap: check EFI for valid memory attributes
Check the EFI memory map so we can use the correct memory attributes for
ioremap().  Previously, we always used uncacheable access, which blows up on
some machines for regular system memory.

136939a2b5 [PATCH] EFI, /dev/mem: simplify efi_mem_attribute_range()
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.
