This fix was proposed by Trond Myklebust. He says: The type "sector_t" is
heavily tied in to the block layer interface as an offset/handle to a block,
and is subject to a supposedly block-specific configuration option:
CONFIG_LBD. Despite this, it is used in struct kstatfs to save a couple of
bytes on the stack whenever we call the filesystems' ->statfs().So kstatfs's entries related to blocks are invalid on statfs64 for a network
filesystem which has more than 2^32-1 blocks when CONFIG_LBD is disabled.- struct kstatfs
Change the type of following entries from sector_t to u64.

f_bfree
f_bavail
f_files

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.Signed-off-by: Takashi Sato

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".Signed-off-by: Takashi Sato

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).Signed-off-by: Andrew Morton

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.Cc: Mark Gross

posix_test_lock() is called either before or after posix_lock_file() to

lock parameter to __posix_lock_file() , changing the name to
__posix_lock_file_conf().Keep posix_lock_file() interface, add posix_lock_conf() interface, both
call __posix_lock_file_conf().[akpm@osdl.org: Put the EXPORT_SYMBOL() where it belongs]

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.Signed-off-by: Eric Dumazet

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 :).[bunk@stusta.de: make ipmi_find_bmc_guid() static]
