When aspect_ratio_crop_init() fails, curr_stream needs
to be freed just like what we've done in the following
error paths. However, current code is returning directly
and ends up leaking memory.

On platforms that define HAVE_ARCH_HUGE_VMAP and support PMD vmaps,
vmalloc will attempt to allocate PMD-sized pages first, before falling

vmalloc_to_page returns NULL for addresses mapped by larger pages[*].
Whether or not a vmap is huge depends on the architecture details,
alignments, boot options, etc., which the caller can not be expected
to know. Therefore HUGE_VMAP is a regression for vmalloc_to_page.

When coresight device is in an active session, driver module of
that device should not be removed. Use try_get_module() in
coresight_grab_device() to prevent module to be unloaded.
Use get_device()/put_device() to protect device data
in the middle of active session.

Define a MODULE_DEVICE_TABLE for cpu_debug so module can
be auto loaded on boot.

Allow to build coresight as modules. This gives developers the feasibility to
test their code without reboot.
This series is based on below two series.
- "coresight: allow to build components as modules"
https://lkml.org/lkml/2018/6/5/989
- "coresight: make drivers modular"
Provide name of cpu_debug module in Kconfig help section.

Fix the imbalance in mport_cdev_open.
Call put_device in error path to balance the
refcount that increased by the get_device.

In probe, IRQ is requested before zchan->id is initialized which can be
read in the irq handler. Hence, shift request irq after other initializations
complete.

In the beginning, mm/gup_benchmark.c supported get_user_pages_fast()
only, but right now, it supports the benchmarking of a couple of
get_user_pages() related calls like:
* get_user_pages_fast()
* get_user_pages()
* pin_user_pages_fast()
* pin_user_pages()
The documentation is confusing and needs

[BUG]
After commit 9afc66498a0b ("btrfs: block-group: refactor how we read one
block group item"), cache->length is being assigned after calling
btrfs_create_block_group_cache. This causes a problem since
set_free_space_tree_thresholds is calculate the free-space
