Subject: [PATCH 3/3] powerpc/mm: Use VMALLOC_START to validate addr
Date: Thu, 23 Jun 2022 17:59:22 +0530 [thread overview]
Message-ID: <20220623122922.640980-3-aneesh.kumar@linux.ibm.com> (raw)
In-Reply-To: <20220623122922.640980-1-aneesh.kumar@linux.ibm.com>
Instead of high_memory use VMALLOC_START to validate that the address is
not in the vmalloc range.
