[PULL 24/28] target/arm: Use tlb_set_page_full


From: Peter Maydell
Subject: [PULL 24/28] target/arm: Use tlb_set_page_full
Date: Mon, 10 Oct 2022 15:27:26 +0100

From: Richard Henderson <richard.henderson@linaro.org>

Adjust GetPhysAddrResult to fill in CPUTLBEntryFull,
so that it may be passed directly to tlb_set_page_full.

The change is large, but mostly mechanical.  The major
non-mechanical change is page_size -> lg_page_size.
Most of the time this is obvious, and is related to
TARGET_PAGE_BITS.
