For foreground gc, greedy algorithm should be adapted, which makes
this formula work well:
(2 * (100 / config.overprovision + 1) + 6)
But currently, we fg_gc have a prior to select bg_gc victim segments to gc
first, these victims are selected by cost-benefit algorithm, we can't guarantee
such segments have the small valid blocks, which may destroy the f2fs rule, on
the worstest case, would consume all the free segments.
This patch fix this by add a filter in check_bg_victims, if segment's has # of
valid blocks over overprovision ratio, skip such segments.

It turns out a stakable filesystem like sdcardfs in AOSP can trigger multiple
vfs_create() to lower filesystem. In that case, f2fs will add multiple dentries
having same name which breaks filesystem consistency.
Until upper layer fixes, let's work around by f2fs, which shows actually not
much performance regression.

In blk_mq_sched_dispatch_requests(), we call blk_mq_sched_mark_restart()
after we dispatch requests left over on our hardware queue dispatch
list. This is so we'll go back and dispatch requests from the scheduler.
In this case, it's only necessary to restart the hardware queue that we
are running; there's no reason to run other hardware queues just because
we are using shared tags.
So, split out blk_mq_sched_mark_restart() into two operations, one for
just the hardware queue and one for the whole request queue. The core
code only needs the hctx variant, but I/O schedulers will want to use
both.
This also requires adjusting blk_mq_sched_restart_queues() to always
check the queue restart flag, not just when using shared tags.

Commit 50e1dab86aa2 ("blk-mq-sched: fix starvation for multiple hardware
queues and shared tags") fixed one starvation issue for shared tags.
However, we can still get into a situation where we fail to allocate a
tag because all tags are allocated but we don't have any pending
requests on any hardware queue.
One solution for this would be to restart all queues that share a tag
map, but that really sucks. Ideally, we could just block and wait for a
tag, but that isn't always possible from blk_mq_dispatch_rq_list().
However, we can still use the struct sbitmap_queue wait queues with a
custom callback instead of blocking. This has a few benefits:
1. It avoids iterating over all hardware queues when completing an I/O,
which the current restart code has to do.
2. It benefits from the existing rolling wakeup code.
3. It avoids punting to another thread just to have it block.

Currently, if we call fsync after updating the xattr date belongs to the
file, f2fs needs to trigger checkpoint to keep xattr data consistent. But,
this policy cause low performance as checkpoint will block most foreground
operations and cause unneeded and unrelated IOs around checkpoint.
This patch will reuse regular file recovery policy for xattr node block,
so, we change to write xattr node block tagged with fsync flag to warm
area instead of cold area, and during recovery, we search warm node chain
for fsynced xattr block, and do the recovery.
So, for below application IO pattern, performance can be improved
obviously:
- touch file
- create/update/delete xattr entry in file
- fsync file

We need to flush data writes before flushing last node block writes by using
FUA with PREFLUSH. We don't need to guarantee precedent node writes since if
those are not written, we can't reach to the last node block when scanning
node block chain during roll-forward recovery.
Afterwards f2fs_wait_on_page_writeback guarantees all the IO submission to
disk, which builds a valid node block chain.

Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for the v4.11 cycle
Core changes:
- Augment fwnode_get_named_gpiod() to configure the GPIO pin
immediately after requesting it like all other APIs do. This is a
treewide change also updating all users.
- Pass a GPIO label down to gpiod_request() from
fwnode_get_named_gpiod(). This makes debugfs and the userspace ABI
correctly reflect the current in-kernel consumer of a pin taken
using this abstraction. This is a treewide change also updating all
users.
- Rename devm_get_gpiod_from_child() to
devm_fwnode_get_gpiod_from_child() to reflect the fact that this
function is operating on a fwnode object. This is a treewide change
also updating all users.
- Make it possible to take multiple GPIOs in a single hog of device
tree hogs.
- The refactorings switching GPIO chips to use the .set_config()
callback using standard pin control properties and providing a
backend into the pin control subsystem that were also merged into
the pin control tree naturally appear here too.
Testing instrumentation:
- A whole slew of cleanups and improvements to the mockup GPIO
driver. We now have an extended userspace test exercising the
subsystem, and we can inject interrupts etc from userspace to fully
test the core GPIO functionality.
New drivers:
- New driver for the Cortina Systems Gemini GPIO controller.
- New driver for the Exar XR17V352/354/358 chips.
- New driver for the ACCES PCI-IDIO-16 PCI GPIO card.
Driver changes:
- RCAR: set the irqchip parent device, add fine-grained runtime PM
support.
- pca953x: support optional RESET control line on the chip.
- DaVinci: cleanups and simplifications. Add support for multiple
instances.
- .set_multiple() and naming of lines on more or less all of the
ISA/PCI GPIO controllers.
- mcp23s08: refactored to use regmap as a first step to further
rewrites and modernizations"

In add_node_ranges() when memblock resize happens, the iterator keeps using
the previous freed array. This bug cause hangs on machine where there are
over 128 memory blocks during boot. For example, on machines where memory
interleaving is small.
The problem is seen on T4-4 because it cant have 2T of memory, and memory
is interleaved at 8G. So we have 2T/8G = 256 regions to set node IDs. The
starting size of regions array is 128. Thus, we have to double at least one
time (actually we have to double twice because some memory is already
reserved and thus we need more than 256 regions). We start using an
incorrect pointer to the array after the first doubling.

add_node_ranges() takes 2.6s - 3.6s per 1T of boot time. On machine with 6T
memory it takes 15.4s, on 32T it would take 82s-115s of boot time.
This function sets NUMA ids for memory blocks, and scans the whole memory a
page at a time to do so. But, we could use values in latency groups mask
and match to determine the boundaries without checking every single page.
With the fix the add_node_ranges() time is reduced from 15.4s down to 0.2s
on machine with 6T memory.

Add support for using multiple hugepage sizes simultaneously
on mainline. Currently, support for 256M has been added which
can be used along with 8M pages.
Page tables are set like this (e.g. for 256M page):
VA + (8M * x) -> PA + (8M * x) (sz bit = 256M) where x in [0, 31]
and TSB is set similarly:
VA + (4M * x) -> PA + (4M * x) (sz bit = 256M) where x in [0, 63]
- Testing
Tested on Sonoma (which supports 256M pages) by running stream
benchmark instances in parallel: one instance uses 8M pages and
another uses 256M pages, consuming 48G each.
Boot params used:
default_hugepagesz=256M hugepagesz=256M hugepages=300 hugepagesz=8M
hugepages=10000

====================
sparc64: Jump to boot prom from console on panic
V3 changes:
- patch 02/04: Added SERIAL_SUNHV conditional group for
sunhv_migrate_hvcons_irq in smp_send_stop().
V2 changes:
- Added cover letter patch
Currently Stop-A (L1A) does not make the kernel switch to OBP on panic. This
patchset addresses this issue. Also, now we can cause a jump to OBP by sending
'break' twice from sunhv console. On bare metal, one can send a break by
typing Esc + 'B' + Sysrq (or whatever). On LDOM, press Ctrl + ] in telnet,
and then "send break" at the telnet prompt.

CPU needs to be marked offline before stopping it. When not marked
offline, the xcall receives HV_EWOULDBLOCK and so assumes that not all
CPUs received the message, and retries. After 10000 retries, it finally
fails with fatal mondo timeout.
