User applications frequently hit problems when they try to use
the kernel headers directly, rather than the exported headers.
This adds an explicit warning for this case, and points to
a URL holding an explanation of why this is wrong and what
to do about it.

This patch (as1295) fixes a recently-added bug in the USB serial core.
If certain kinds of errors occur during probing, the core may call a
serial driver's release method without previously calling the attach
method. This causes some drivers (io_ti in particular) to perform an
invalid memory access.
The patch adds a new flag to keep track of whether or not attach has
been called.

After m68k's task_thread_info() doesn't refer to current,
it's possible to remove sched.h from interrupt.h and not break m68k!

Disks formatted with DIF Type 2 reject READ/WRITE 6/10/12/16 commands

Implement support for issusing 32-byte READ/WRITE and enable Type 2
drives in the protection type detection logic.

So far we have only issued DIF commands if CONFIG_BLK_DEV_INTEGRITY is
enabled. However, communication between initiator and target should be
independent of protection information DMA. There are DIF-only host
adapters coming out that will be able to take advantage of this.
Move the relevant DIF bits to sd.c.

The checksum format is orthogonal to whether the protection information
is being passed on beyond the HBA or not. It is perfectly valid to use
a non-T10 CRC with WRITE_STRIP and READ_INSERT.
Consequently it no longer makes sense to explicitly refer to the
conversion in the protection operation. Update sd_dif and lpfc
accordingly.

Since the beginnings in aafe4dbed0bf6cbdb2e9f03e1d42f8a540d8541d
("asm-generic: add generic versions of common headers") the generic
version of <asm/hardirq.h> defined __softirq_pending as unsigned long.
Which is different from other architectures for no apparent good reason
and was causing the following warning:
kernel/time/tick-sched.c: In function 'tick_nohz_stop_sched_tick':
kernel/time/tick-sched.c:261: warning: format '%02x' expects type 'unsigned int', but argument 2 has type 'long unsigned int'

[ Arnd points out that we really should make sure parisc and alpha are
ok with this, since they have also been converted to use the generic
hardirq.h file. But neither seems to use it, although parisc does
build a IRQSTAT_SIRQ_PEND #define into asm-offsets - but that also
appears unused.. - Linus ]

The original driver was written with the KEY() macro defined as (col,
row) instead of (row, col) as defined by the matrix keypad
infrastructure. So the keymap was defined accordingly. Since the
driver that was merged upstream uses the matrix keypad infrastructure,
modify the keymap accordingly.
While we are at it, fix the comments in twl4030.h and define
PERSISTENT_KEY as (r,c) instead of (c, r)
Tested on a RX51 (N900) device.

o Move the module_param statements for blimit, qhimark, and

o In __rcu_offline_cpu(), move the assignment to rdp_me
inside the "if" statement, given that rdp_me is not used
outside of that "if" statement.

These issues identified during an old-fashioned face-to-face code
review extending over many hours.
o Add comments for tricky parts of code, and correct comments
that have passed their sell-by date.
o Get rid of the vestiges of rcu_init_sched(), which is no
longer needed now that PREEMPT_RCU is gone.
o Move the #include of rcutree_plugin.h to the end of
rcutree.c, which means that, rather than having a random
collection of forward declarations, the new set of forward
declarations document the set of plugins. The new home for
this #include also allows __rcu_init_preempt() to move into
rcutree_plugin.h.
o Fix rcu_preempt_check_callbacks() to be static.

These issues identified during an old-fashioned face-to-face code
review extended over many hours.
o Bury various forms of the "rsp->completed == rsp->gpnum"
comparison into an rcu_gp_in_progress() function, which has
the beneficial side-effect of forcing consistent use of
ACCESS_ONCE().
o Replace hand-coded arithmetic with DIV_ROUND_UP().
o Bury several "!list_empty(&rnp->blocked_tasks[rnp->gpnum & 0x01])"
instances into an rcu_preempted_readers() function, as this
expression indicates that there are no readers blocked
within RCU read-side critical sections blocking the current
grace period. (Though there might well be similar readers
blocking the next grace period.)
o Remove a dangling rcu_restart_cpu() declaration that has
been dangling for almost 20 minor releases of the kernel.

When the module is about the unload we release its call records.
The ftrace_release function was given wrong values representing
the module core boundaries, thus not releasing its call records.
Plus making ftrace_release function module specific.

Some architectures such as Sparc, ARM and MIPS (basically
everything with flush_dcache_page()) need to deal with dcache
aliases by carefully placing pages in both kernel and user maps.
These architectures typically have to use vmalloc_user() for this.
However, on other architectures, vmalloc() is not needed and has
the downsides of being more restricted and slower than regular
allocations.

The previous patches had some unwanted side effects, I've fixed
the lack of 32bpp working, and fixed up 16bpp so it should also work.
this also adds the interface to allow the driver to set a preferred
console depth so for example low memory rn50 can set it to 8bpp.
It also catches 24bpp on cards that can't do it and forces 32bpp.
Tested on r100/r600/i945.

The following user-space program fails to compile:
#include <linux/socket.h>
#include <sys/socket.h>
int main() { return 0; }
The reason is that <linux/socket.h> tests __GLIBC__ to decide whether it
should define various structures and macros that are now defined for
user-space by <sys/socket.h>, but __GLIBC__ is not defined if no libc
headers have yet been included.
It seems safe to drop support for libc 5 now.

Global values for service time and utilization are garbage. For
interval values, utilization is always 100%, and service time is
higher than normal.
I bisected it down to:
[a9327cac440be4d8333bba975cbbf76045096275] Seperate read and write
statistics of in_flight requests
and verified that reverting just that commit indeed solves the issue
on 2.6.32-rc1."
So until this is debugged, revert the bad commit.

Not all users of the topology information want to use libblkid. Provide
the topology information through bdev ioctls.
Also clarify sector size comments for existing BLK ioctls.

This slowly ramps up the async queue depth based on the time
passed since the sync IO, and doesn't allow async at all until
a sync slice period has passed.

Since 2.6.31 now has request-based device-mapper, it's useful to have
a tracepoint for request-remapping as well as bio-remapping.
This patch adds a tracepoint for request-remapping, trace_block_rq_remap().

Currently we set the bio size to the byte equivalent of the blocks to
be trimmed when submitting the initial DISCARD ioctl. That means it
is subject to the max_hw_sectors limitation of the HBA which is
much lower than the size of a DISCARD request we can support.
Add a separate max_discard_sectors tunable to limit the size for discard
requests.
We limit the max discard request size in bytes to 32bit as that is the
limit for bio->bi_size. This could be much larger if we had a way to pass
that information through the block layer.

prepare_discard_fn() was being called in a place where memory allocation
was effectively impossible. This makes it inappropriate for all but
the most trivial translations of Linux's DISCARD operation to the block
command set. Additionally adding a payload there makes the ownership
of the bio backing unclear as it's now allocated by the device driver
and not the submitter as usual.
It is replaced with QUEUE_FLAG_DISCARD which is used to indicate whether
the queue supports discard operations or not. blkdev_issue_discard now
allocates a one-page, sector-length payload which is the right thing
for the common ATA and SCSI implementations.
The mtd implementation of prepare_discard_fn() is replaced with simply
checking for the request being a discard.
Largely based on a previous patch from Matthew Wilcox <matthew@wil.cx>
which did the prepare_discard_fn but not the different payload allocation
yet.
