Please put "staging:" in your subject line, makes it easier to sort and
handle. It should look something like:
staging: kpc2000_spi: fix line length issues
This adds tests which will validate architecture page table helpers and
other accessors in their compliance with expected generic MM semantics.
This will help various architectures in validating changes to existing
page table helpers or addition of new ones.

alloc_gigantic_page() implements an allocation method where it scans over
various zones looking for a large contiguous memory block which could not
have been allocated through the buddy allocator. A subsequent patch which
tests arch page table helpers needs such a method to allocate PUD_SIZE

This series adds a test validation for architecture exported page table
helpers. Patch in the series adds basic transformation tests at various
levels of the page table. Before that it exports gigantic page allocation

Hi Eric:
My apologies for bothering, we got those report via static analysis
and haven't got a good method to verify the path to trigger them.
Therefore I sent those email to you maintainers first since you
know much better about the details. Sorry again for your time and
I take your suggestions.
In case of error, the function devm_ioremap_resource() returns ERR_PTR()
and never returns NULL. The NULL test in the return value check should
be replaced with IS_ERR().

perf record has supported --all-kernel / --all-user to configure all

It would be useful to support these options in perf-stat too to keep

Hi Joe,

Introduce offsets for time namespace. They will contain an adjustment

A new namespace is created with the same offsets as the time namespace
