If split page table lock is in use, we embed the lock into struct page
of table's page. We have to disable split lock, if spinlock_t is too
big be to be embedded, like when DEBUG_SPINLOCK or DEBUG_LOCK_ALLOC
enabled.
This patch add support for dynamic allocation of split page table lock
if we can't embed it to struct page.
page->ptl is unsigned long now and we use it as spinlock_t if
sizeof(spinlock_t) <= sizeof(long), otherwise it's pointer to spinlock_t.
The spinlock_t allocated in pgtable_page_ctor() for PTE table and in
pgtable_pmd_page_ctor() for PMD table. All other helpers converted to
support dynamically allocated page->ptl.

At the moment xtensa uses slab allocator for PTE table. It doesn't work
with enabled split page table lock: slab uses page->slab_cache and
page->first_page for its pages. These fields share stroage with
page->ptl.

In split page table lock case, we embed spinlock_t into struct page.
For obvious reason, we don't want to increase size of struct page if
spinlock_t is too big, like with DEBUG_SPINLOCK or DEBUG_LOCK_ALLOC or
on -rt kernel. So we disable split page table lock, if spinlock_t is
too big.
This patchset allows to allocate the lock dynamically if spinlock_t is
big. In this page->ptl is used to store pointer to spinlock instead of
spinlock itself. It costs additional cache line for indirect access,
but fix page fault scalability for multi-threaded applications.
LOCK_STAT depends on DEBUG_SPINLOCK, so on current kernel enabling
LOCK_STAT to analyse scalability issues breaks scalability. ;)
The patchset mostly fixes this. Results for ./thp_memscale -c 80 -b 512M
on 4-socket machine:
baseline, no CONFIG_LOCK_STAT: 9.115460703 seconds time elapsed
baseline, CONFIG_LOCK_STAT=y: 53.890567123 seconds time elapsed
patched, no CONFIG_LOCK_STAT: 8.852250368 seconds time elapsed
patched, CONFIG_LOCK_STAT=y: 11.069770759 seconds time elapsed
Patch count is scary, but most of them trivial. Overview:
Patches 1-4 Few bug fixes. No dependencies to other patches.
Probably should applied as soon as possible.
Patch 5 Changes signature of pgtable_page_ctor(). We will use it
for dynamic lock allocation, so it can fail.
Patches 6-8 Add missing constructor/destructor calls on few archs.
It's fixes NR_PAGETABLE accounting and prepare to use
split ptl.
Patches 9-33 Add pgtable_page_ctor() fail handling to all archs.
Patches 34 Finally adds support of dynamically-allocated page->pte.
Also contains documentation for split page table lock.
This patch (of 34):
I've missed that we preallocate few pmds on pgd_alloc() if X86_PAE
enabled. Let's add missed constructor/destructor calls.
I haven't noticed it during testing since prep_new_page() clears
page->mapping and therefore page->ptl. It's effectively equal to
spin_lock_init(&page->ptl).

Currently mm->pmd_huge_pte protected by page table lock. It will not

For now, let's just introduce wrapper to access mm->pmd_huge_pte.

CONFIG_NO_HZ_FULL requires possibility of smp_send_reschedule()
for the calling CPU. Currently, it is used in inc_nr_running()
scheduler primitive only.
Nobody calls smp_send_reschedule() from preemptible context
(furthermore, it looks like it will be save if anybody use it
another way in the future). But anyway I add WARN_ON() here
just to return here if anything changes.

Simba-bridges
The SIMBA APB Bridges lacks the 'ranges' of-property describing the
PCI I/O and memory areas located beneath the bridge. Faking this
information has been performed by reading range registers in the
APB bridge, and calculating the corresponding areas.
In commit 01f94c4a6ced476ce69b895426fc29bfc48c69bd
("Fix sabre pci controllers with new probing scheme.") a bug was
introduced into this calculation, causing the PCI memory areas
to be calculated incorrectly: The shift size was set to be
identical for I/O and MEM ranges, which is incorrect.
This patch set the shift size of the MEM range back to the
value used before 01f94c4a6ced476ce69b895426fc29bfc48c69bd.

Modify struct acpi_dev_node to contain a pointer to struct acpi_device
associated with the given device object (that is, its ACPI companion
device) instead of an ACPI handle corresponding to it. Introduce two
new macros for manipulating that pointer in a CONFIG_ACPI-safe way,
ACPI_COMPANION() and ACPI_COMPANION_SET(), and rework the
ACPI_HANDLE() macro to take the above changes into account.
Drop the ACPI_HANDLE_SET() macro entirely and rework its users to
use ACPI_COMPANION_SET() instead. For some of them who used to
pass the result of acpi_get_child() directly to ACPI_HANDLE_SET()
introduce a helper routine acpi_preset_companion() doing an
equivalent thing.
The main motivation for doing this is that there are things
represented by struct acpi_device objects that don't have valid
ACPI handles (so called fixed ACPI hardware features, such as
power and sleep buttons) and we would like to create platform
device objects for them and "glue" them to their ACPI companions
in the usual way (which currently is impossible due to the
lack of valid ACPI handles). However, there are more reasons
why it may be useful.
First, struct acpi_device pointers allow of much better type checking
than void pointers which are ACPI handles, so it should be more
difficult to write buggy code using modified struct acpi_dev_node
and the new macros. Second, the change should help to reduce (over
time) the number of places in which the result of ACPI_HANDLE() is
passed to acpi_bus_get_device() in order to obtain a pointer to the
struct acpi_device associated with the given "physical" device,
because now that pointer is returned by ACPI_COMPANION() directly.
Finally, the change should make it easier to write generic code that
will build both for CONFIG_ACPI set and unset without adding explicit
compiler directives to it.

Add a single-vendor config for vt8500. We can't enable WM8750 in
multi_v7_defconfig since it's a v6-based device, but it's still valuable
to have an in-tree defconfig that is suitable for the hardware.
This is based on multi_v7_defconfig and can be tweaked over time. It
gets us off the ground for now. Naming it vt8500_v6_v7 similar to i.MX
since there are v5-based vt8500 chips as well.
