Subject: [PATCH v6 19/33] arm: Convert various functions to use ptdescs
Date: Mon, 26 Jun 2023 20:14:17 -0700 [thread overview]
Message-ID: <20230627031431.29653-20-vishal.moola@gmail.com> (raw)
In-Reply-To: <20230627031431.29653-1-vishal.moola@gmail.com>
As part of the conversions to replace pgtable constructor/destructors with
ptdesc equivalents, convert various page table functions to use ptdescs.
late_alloc() also uses the __get_free_pages() helper function. Convert
this to use pagetable_alloc() and ptdesc_address() instead to help
standardize page tables further.
