More code can be pushed from rwsem_down_read_failed and
rwsem_down_write_failed into rwsem_down_failed_common.Following change adding down_read_critical infrastructure support also
enjoys having flags available in a register rather than having to fish it
out in the struct rwsem_waiter...Signed-off-by: Michel Lespinasse

This change addresses the following situation:
- Thread A acquires the rwsem for read
- Thread B tries to acquire the rwsem for write, notices there is already
an active owner for the rwsem.
- Thread C tries to acquire the rwsem for read, notices that thread B already
tried to acquire it.
- Thread C grabs the spinlock and queues itself on the wait queue.
- Thread B grabs the spinlock and queues itself behind C. At this point A is
the only remaining active owner on the rwsem.In this situation thread B could notice that it was the last active writer
on the rwsem, and decide to wake C to let it proceed in parallel with A
since they both only want the rwsem for read.Signed-off-by: Michel Lespinasse

Previously each waiting thread added a bias of RWSEM_WAITING_BIAS. With
this change, the bias is added only once to indicate that the wait list is
non-empty.This has a few nice properties which will be used in following changes:
- when the spinlock is held and the waiter list is known to be non-empty,
count < RWSEM_WAITING_BIAS there is an active writer on that sem
- count == RWSEM_WAITING_BIAS there are waiting threads and no
active readers/writers on that semSigned-off-by: Michel Lespinasse

In __rwsem_do_wake(), we can skip the active count check unless we come
there from up_xxxx(). Also when checking the active count, it is not
actually necessary to increment it; this allows us to get rid of the read
side undo code and simplify the calculation of the final rwsem count
adjustment once we've counted the reader threads to wake.The basic observation is the following. When there are waiter threads on
a rwsem and the spinlock is held, other threads can only increment the
active count by trying to grab the rwsem in down_xxxx(). However
down_xxxx() will notice there are waiter threads and take the down_failed
path, blocking to acquire the spinlock on the way there. Therefore, a
thread observing an active count of zero with waiters queued and the
spinlock held, is protected against other threads acquiring the rwsem
until it wakes the last waiter or releases the spinlock.Signed-off-by: Michel Lespinasse

This is in preparation for later changes in the series.
In __rwsem_do_wake(), the first queued waiter is checked first in order to
determine whether it's a writer or a reader. The code paths diverge at
this point. The code that checks and increments the rwsem active count is
duplicated on both sides - the point is that later changes in the series
will be able to independently modify both sides.Signed-off-by: Michel Lespinasse

Add percpu_counter_compare that allows for a quick but accurate comparison
of percpu_counter with a given value.A rough count is provided by the count field in percpu_counter structure,
without accounting for the other values stored in individual cpu counters.The actual count is a sum of count and the cpu counters. However, count
field is never different from the actual value by a factor of
batch*num_online_cpu. We do not need to get actual count for comparison
if count is different from the given value by this factor and allows for
quick comparison without summing up all the per cpu counters.Signed-off-by: Tim Chen

kmemleak ignores page_alloc() and so believes the final sub-page
allocation using the plain kmalloc is decoupled and lost. This leads to
lots of false-positives with code that uses scatterlists.The options seem to be either to tell kmemleak that the kmalloc is not
leaked or to notify kmemleak of the page allocations. The danger of the
first approach is that we may hide a real leak, so choose the latter
approach (of which I am not sure of the downsides).v2: Added comments on the suggestion of Catalin.

Newer gcc has a -femit-struct-debug-baseonly option that dramatically
reduces the size of object files with debug info. What it does
is to only emit type information for structures when the structures
are defined in the same file or in a header file.This means the type information for most headers are not included.
This is not good when the type information is actually
needed (e.g. with kgdb or systemtap)But often kernel hackers only care about line numbers and don't
need all the type information anyways. In this case setting
the option can be a big win:A build dir for a specific x86-64 configuration with gcc 4.5
shrunk from 2.3G to 1.2G. The compilation was also nearly a minute

Current x86 ioremap() doesn't handle physical address higher than
32-bit properly in X86_32 PAE mode. When physical address higher than
32-bit is passed to ioremap(), higher 32-bits in physical address is
cleared wrongly. Due to this bug, ioremap() can map wrong address to
linear address space.In my case, 64-bit MMIO region was assigned to a PCI device (ioat
device) on my system. Because of the ioremap()'s bug, wrong physical
address (instead of MMIO region) was mapped to linear address space.
Because of this, loading ioatdma driver caused unexpected behavior
(kernel panic, kernel hangup, ...).Signed-off-by: Kenji Kaneshige

Reimplement augmented RB-trees without sprinkling extra branches
all over the RB-tree code (which lives in the scheduler hot path).This approach is 'borrowed' from Fabio's BFQ implementation and
relies on traversing the rebalance path after the RB-tree-op to
correct the heap property for insertion/removal and make up for
the damage done by the tree rotations.For insertion the rebalance path is trivially that from the new
node upwards to the root, for removal it is that from the deepest
node in the path from the to be removed node that will still
be around after the removal.[ This patch also fixes a video driver regression reported by
Ali Gholami Rudi - the memtype->subtree_max_end was updated
incorrectly. ]Acked-by: Suresh Siddha
