[PATCH v4 0/2] kho: add support for deferred struct page init

[Michal Clapinski]

When CONFIG_DEFERRED_STRUCT_PAGE_INIT (hereinafter DEFERRED) is
enabled, struct page initialization is deferred to parallel kthreads
that run later in the boot process.

Currently, KHO is incompatible with DEFERRED.
This series fixes that incompatibility.
