The driver uses pm_runtime_put_noidle() after initialization so the
device might remain in active state if the core does not read from it
(the read callback contains regular runtime put). The put_noidle() was
chosen probably to avoid unneeded suspend and resume cycle after the
initialization.

Zsmalloc is ready for page migration so zram can use __GFP_MOVABLE
from now on.
I did test to see how it helps to make higher order pages.

This patch cleans up function parameter "struct page".
Many functions of zsmalloc expects that page paramter is "first_page"
so use "first_page" rather than "page" for code readability.

A useful use case for min_t and max_t is comparing two values with larger
type. For example comparing an u64 and an u32, usually we do not want to
truncate the u64, so we need use min_t or max_t with u64.
To simplify the usage introducing two more macros min_lt and max_lt,
'lt' means larger type.
Hi,
We found a min_t type casting issue in fs/proc/vmcore.c, it uses smaller
type in min_t so that during i386 PAE testing 64bit value was trucated

and it can cause triming down variables in below calculation in

Then the real size passed down is not correct any more.

Small series that fixes/completes DT bindings for Tegra GPUs and add two
missing entries required for the Tegra210 GPU to operate properly.
Alexandre Courbot (5):
dt-bindings: gk20a: Fix typo in compatible name
dt-bindings: gk20a: Document iommus property
dt-bindings: Add documentation for G
This clock is required for the GPU to operate.

Nouveau can take advantage of this declaration to remove the need for
contiguous memory.

Check inline data flag ahead, so we can save some
cpu cycle.

Remove the f2fs_has_inline_data for f2fs_fiemap, and let
f2fs_inline_data_fiemap take over gatekeeper of checking
inline data flag.

No matter inline data flag is set or not, get_node_page is
going work now. But actually we can avoid it by puting the
check of inline data flag in advance to save this cpu cycle.

If failing to check inline data flag for f2fs_convert_inline_inode,
it will return 0. So we don't need to check it twice before we are
going to do f2fs_convert_inline_page.

This patchset is going to remove some redunant checking
of inline data flag and also going to avoid some unnecessary
cpu waste when doing inline stuff.
Note:
Sorry for sending previous four patches in separate, let
drop them and make them in this thread for better review.

Improve the test to allow casts to (unsigned) or (signed) to be
found and fixed if desired.
