Subject: [PATCH v2 0/2] kho: clean up page initialization logic

From: "Pratyush Yadav (Google)" <pratyush@...nel.org>

Hi,

This series simplifies the page initialization logic in kho_restore_page(). It
was originally only a single patch [0], but on Pasha's suggestion, I added
another patch to use unsigned long for nr_pages.

Technically speaking, the patches aren't related and can be applied
independently, but bundling them together since patch 2 relies on 1 and it is
easier to manage them this way.

Changes in v2:
- Use unsigned long for nr_pages.
