We cannot optimize if a "struct page" crosses page boundaries. If
it is true, we can optimize the code with the help of a compiler.
When free_vmemmap_pages_per_hpage() returns zero, most functions are
optimized by the compiler.

For HugeTLB page, there are more metadata to save in the struct page.
But the head struct page cannot meet our needs, so we have to abuse

Add quirks to support them.

Thanks for the patch! It
Hi,
I have an Intel NUC D54250WYK which no longer shuts down properly after
moving from 5.9.16 to 5.10.4, because systemd hangs. The kernel logs
make me beleive it is likely a locking issue in either DRM or ALSA or
both. Relevant messages which I could extract from the journal:

Hi,
This series updates omap4-keypad to disable unused long interrupts, and
implements the missing parts for the lost key-up interrupt quirk as
described in the silicon errata pdf. It also simplifies the probe to
use devm.
Regards,
Tony
Changes since v3:
- Use PM runtime to check the last
We are still missing handling for errata i689 related issues for the
case where we never see a key up interrupt for the last pressed key.
To fix the issue, we must scan the key state again after the keyboard
controller has idled to check if a key up event was missed. This is
described in the
We are not using the long events and they produce extra interrupts.
Let's not enable them at all.
Note that also the v3.0.8 Linux Android kernel has long interrupts
disabled.

Because of errata i689 the keyboard can idle with state where no key
up interrupts are seen until after the next key press.
This means we need to first check for any lost key up events before
scanning for new down events.
For example, rapidly pressing shift-shift-j can sometimes produce a J

These should list exact models, not wildcards.
