Subject: [PATCH v3 14/34] microblaze: Implement the new page table range API
Date: Tue, 28 Feb 2023 21:37:17 +0000 [thread overview]
Message-ID: <20230228213738.272178-15-willy@infradead.org> (raw)
In-Reply-To: <20230228213738.272178-1-willy@infradead.org>
Add set_ptes(), update_mmu_cache_range(), flush_icache_pages() and
flush_dcache_folio(). Also change the calling convention for set_pte()
to be the same as other architectures.
