Subject: [PATCH V2 1/7] m68k/mm: Change pmd_val()
Date: Tue, 17 Sep 2024 13:01:11 +0530	[thread overview]
Message-ID: <20240917073117.1531207-2-anshuman.khandual@arm.com> (raw)
In-Reply-To: <20240917073117.1531207-1-anshuman.khandual@arm.com>

This changes platform's pmd_val() to access the pmd_t element directly like
other architectures rather than current pointer address based dereferencing
that prevents transition into pmdp_get().
