The lock is released first thing in all three branches. Simplify this by
unconditionally releasing lock and remove else clause which was only there
to be sure lock was released.

SECTION_ALIGN_DOWN() macros
Commit a539f3533b78e3 ("mm: add SECTION_ALIGN_UP() and
SECTION_ALIGN_DOWN() macro") introduced the SECTION_ALIGN_UP() and
SECTION_ALIGN_DOWN() macros. Use those macros to increase code
readability.

Commit bae9c19bf1 ("thp: split_huge_page_mm/vma") changed locking behavior

Originally, walk_hugetlb_range() didn't require a caller take any lock.
But commit d33b9f45bd ("mm: hugetlb: fix hugepage memory leak in
walk_page_range") changed its rule. Because it added find_vma() call in
walk_hugetlb_range().
Any locking-rule change commit should write a doc too.

Currently, walk_page_range() calls find_vma() every page table for walk
iteration. but it's completely unnecessary if walk->hugetlb_entry is
unused. And we don't have to assume find_vma() is a lightweight
operation. So this patch checks the walk->hugetlb_entry and avoids the
find_vma() call if possible.
This patch also makes some cleanups. 1) remove ugly uninitialized_var()
and 2) #ifdef in function body.

The doc of find_vma() says,
/* Look up the first VMA which satisfies addr < vm_end, NULL if none. */
struct vm_area_struct *find_vma(struct mm_struct *mm, unsigned long addr)
{
(snip)
Thus, caller should confirm whether the returned vma matches a desired one.

Memory hotplug support for Xen balloon driver. It should be mentioned
that hotplugged memory is not onlined automatically. It should be onlined
by user through standard sysfs interface.
Memory could be hotplugged in following steps:
1) dom0: xl mem-max <domU> <maxmem>
where <maxmem> is >= requested memory size,
2) dom0: xl mem-set <domU> <memory>
where <memory> is requested memory size; alternatively memory
could be added by writing proper value to
/sys/devices/system/xen_memory/xen_memory0/target or
/sys/devices/system/xen_memory/xen_memory0/target_kb on dumU,
3) domU: for i in /sys/devices/system/memory/memory*/state; do \
[ "`cat "$i"`" = offline ] && echo online > "$i"; done
Memory could be onlined automatically on domU by adding following line to
udev rules:
SUBSYSTEM=="memory", ACTION=="add", RUN+="/bin/sh -c '[ -f /sys$devpath/state ] && echo online > /sys$devpath/state'"
In that case step 3 should be omitted.

This patch contains online_page_callback and apropriate functions for
registering/unregistering online page callbacks. It allows to do some
machine specific tasks during online page stage which is required to
implement memory hotplug in virtual machines. Currently this patch is
required by latest memory hotplug support for Xen balloon driver patch
which will be posted soon.
Additionally, originial online_page() function was splited into
following functions doing "atomic" operations:
- __online_page_set_limits() - set new limits for memory management code,
- __online_page_increment_counters() - increment totalram_pages and totalhigh_pages,
- __online_page_free() - free page to allocator.
It was done to:
- not duplicate existing code,
- ease hotplug code devolpment by usage of well defined interface,
- avoid stupid bugs which are unavoidable when the same code
(by design) is developed in many places.

Vito said:

: This then leads to an unrelated starvation problem caused by write-heavy

If a semaphore array is removed and in parallel a sleeping task is woken
up (signal or timeout, does not matter), then the woken up task does not
wait until wake_up_sem_queue_do() is completed. This will cause crashes,
because wake_up_sem_queue_do() will read from a stale pointer.
The fix is simple: Regardless of anything, always call get_queue_result().
This function waits until wake_up_sem_queue_do() has finished it's task.

The "fsuid is the inode owner" case is not necessarily always the likely
case, but it's the case that doesn't do anything odd and that we want in
straight-line code. Make gcc not generate random "jump around for the

This just helps me read profiles. That thing is one of the hottest

We should only include support for the ISA interface of the LM78/LM79
if CONFIG_ISA is set. Not only this makes the driver somewhat smaller
on most architectures, but this also avoids poking at random I/O
ports on these architectures.
This is very similiar to what was done for the w83781d driver in
October 2008.

This patch adds a new driver for SMSC SCH5636 Super I/O chips.
The chips include an embedded microcontroller for hardware monitoring
solutions, allowing motherboard manufacturers to create their own
custom hwmon solution based upon the SCH5636.
Currently the sch5636 driver only supports the Fujitsu Theseus SCH5636
based hwmon solution. The sch5636 driver runs a sanity check on
loading to ensure it is dealing with a Fujitsu Theseus and not with
another custom SCH5636 based hwmon solution.

Replace the ->check_acl method with a ->get_acl method that simply reads an
ACL from disk after having a cache miss. This means we can replace the ACL
checking boilerplate code with a single implementation in namei.c.

made static; no callers left outside of posix_acl.c. posix_acl_clone() also
has lost all external callers and became static...

new helper: posix_acl_create(&acl, gfp, mode_p). Replaces acl with
modified clone, on failure releases acl and replaces with NULL.
Returns 0 or -ve on error. All callers of posix_acl_create_masq()
switched.

In-core acls are copy-on-write, so the reference taken by set_cached_acl() will
do just fine.

new helper: posix_acl_chmod(&acl, gfp, mode). Replaces acl with modified
clone or with NULL if that has failed; returns 0 or -ve on error. All
callers of posix_acl_chmod_masq() switched to that - they'd been doing
exactly the same thing.

Always set up a negative ACL cache entry if the inode can't have ACLs.
That behaves much better than doing this check inside ->check_acl.
Also remove the left over MAY_NOT_BLOCK check.
