Subject: [PATCH v30 13/32] mm: Move VM_UFFD_MINOR_BIT from 37 to 38
Date: Mon, 30 Aug 2021 11:15:09 -0700 [thread overview]
Message-ID: <20210830181528.1569-14-yu-cheng.yu@intel.com> (raw)
In-Reply-To: <20210830181528.1569-1-yu-cheng.yu@intel.com>
To introduce VM_SHADOW_STACK as VM_HIGH_ARCH_BIT (37), and make all
VM_HIGH_ARCH_BITs stay together, move VM_UFFD_MINOR_BIT from 37 to 38.
