[PATCH] Avoid disk sector_t overflow for >2TB ext3 filesystem
If ext3 filesystem is larger than 2TB, and sector_t is a u32 (i.e.
CONFIG_LBD not defined in the kernel), the calculation of the disk sector
will overflow. Add check at ext3_fill_super() and ext3_group_extend() to
prevent mount/remount/resize >2TB ext3 filesystem if sector_t size is 4
bytes.
Verified this patch on a 32 bit platform without CONFIG_LBD defined
(sector_t is 32 bits long), mount refuse to mount a 10TB ext3.

schedule_on_each_cpu() presently does a large kmalloc - 96 kbytes on 1024 CPU
64-bit.
Rework it so that we do one 8192-byte allocation and then a pile of tiny ones,
via alloc_percpu(). This has a much higher chance of success (100% in the
current VM).
This also has the effect of reducing the memory requirements from NR_CPUS*n to
num_possible_cpus()*n.

[PATCH] Make printk work for really early debugging
Currently printk is no use for early debugging because it refuses to
actually print anything to the console unless
cpu_online(smp_processor_id()) is true.
The stated explanation is that console drivers may require per-cpu
resources, or otherwise barf, because the system is not yet setup
correctly. Fair enough.
However some console drivers might be quite happy running early during
boot, in fact we have one, and so it'd be nice if printk understood that.
So I added a flag (which I would have called CON_BOOT, but that's taken)
called CON_ANYTIME, which indicates that a console is happy to be called
anytime, even if the cpu is not yet online.
Tested on a Power 5 machine, with both a CON_ANYTIME driver and a bogus
console driver that BUG()s if called while offline. No problems AFAICT.

[PATCH] ufs: not usual amounts of fragments per block
The writing to UFS file system with block/fragment!=8 may cause bogus
behaviour. The problem in "ufs_bitmap_search" function, which doesn't work
correctly in "block/fragment!=8" case. The idea is stolen from BSD code.
There are two ugly macros in ufs code:
#define UCPI_UBH ((struct ufs_buffer_head *)ucpi)
#define USPI_UBH ((struct ufs_buffer_head *)uspi)
when uspi looks like
struct {
struct ufs_buffer_head ;
}
and USPI_UBH has some sence,
ucpi looks like
struct {
struct not_ufs_buffer_head;
}
To prevent bugs in future, this patch convert macros to inline function and
fix "ucpi" structure.
First of all some necessary notes about UFS by it self: To avoid waste of disk
space the tail of file consists not from blocks (which is ordinary big enough,
16K usually), it consists from fragments(which is ordinary 2K). When file is
growing its tail occupy 1 fragment, 2 fragments... At some stage decision to
allocate whole block is made and all fragments are moved to one block.
bh = sb_bread
bh->b_blocknr = result + i;
mark_buffer_dirty (bh);
This is wrong solution, because:
- it didn't take into consideration that there is another cache: "inode page
cache"
- because of sb_getblk uses not b_blocknr, (it uses page->index) to find
certain block, this breaks sb_getblk.
How this situation is handled now: we go though all "page inode cache", if
there are no such page in cache we load it into cache, and change b_blocknr.
Currently, ufs write support have two sets of problems: work with files and
work with directories.
This series of patches should solve the first problem.
This patch is similar to http://lkml.org/lkml/2006/1/17/61 this patch
complements it.
The situation the same: in ufs_trunc_(not direct), we read block, check if
count of links to it is equal to one, if so we finish cycle, if not
continue. Because of "count of links" always >=2 this operation cause
infinite cycle and hang up the kernel.

Hooks for calling vma specific migration functions
With this patch a vma may define a vma->vm_ops->migrate function. That
function may perform page migration on its own (some vmas may not contain page
structs and therefore cannot be handled by regular page migration. Pages in a
vma may require special preparatory treatment before migration is possible
etc) . Only mmap_sem is held when the migration function is called. The
migrate() function gets passed two sets of nodemasks describing the source and
the target of the migration. The flags parameter either contains
MPOL_MF_MOVE which means that only pages used exclusively by
the specified mm should be moved
or
MPOL_MF_MOVE_ALL which means that pages shared with other processes
should also be moved.
The migration function returns 0 on success or an error condition. An error
condition will prevent regular page migration from occurring.
On its own this patch cannot be included since there are no users for this
functionality. But it seems that the uncached allocator will need this
functionality at some point.

Nick Piggin rightly pointed out that the introduction of AOP_TRUNCATED_PAGE
to read_pages() was wrong to leave A_T_P victim pages in the page cache but
not put them in the LRU. Failing to do so hid them from the VM.
A_T_P just means that the aop method unlocked the page rather than
performing IO. It would be very rare that the page was truncated between
the unlock and testing A_T_P. So we leave the pages in the LRU for likely
reuse soon rather than backing them back out of the page cache. We do this
by matching the behaviour before the A_T_P introduction which added pages
to the LRU regardless of what ->readpage() did.
This doesn't include the unrelated cleanup in Nick's initial fix which
changed read_pages() to return void to match its only caller's behaviour of
ignoring errors.

Enable minimal per-device resume tracing
This is the minimal resume trace code to find which device resume (if
any) results in problems. Usually, you'd use the information this
generates as a starting point to adding more fine-grained trace event
points.

[ARM] Add identifying number for non-rt sigframe
GDB couldn't reliably tell the difference between the old and new
non-rt sigframes, so provide it with a number at the beginning which
will never appear in the old sigframe, and hence provide gdb with a
reliable way to tell the two apart.
