Subject: [PATCH V7 11/26] xtensa/mm: Enable ARCH_HAS_VM_GET_PAGE_PROT
Date: Mon, 11 Jul 2022 12:35:45 +0530 [thread overview]
Message-ID: <20220711070600.2378316-12-anshuman.khandual@arm.com> (raw)
In-Reply-To: <20220711070600.2378316-1-anshuman.khandual@arm.com>
This enables ARCH_HAS_VM_GET_PAGE_PROT on the platform and exports standard
vm_get_page_prot() implementation via DECLARE_VM_GET_PAGE_PROT, which looks
up a private and static protection_map[] array. Subsequently all __SXXX and
__PXXX macros can be dropped which are no longer needed.

Subject: [PATCH V7 11/26] xtensa/mm: Enable ARCH_HAS_VM_GET_PAGE_PROT
Date: Mon, 11 Jul 2022 12:35:45 +0530 [thread overview]
Message-ID: <20220711070600.2378316-12-anshuman.khandual@arm.com> (raw)
In-Reply-To: <20220711070600.2378316-1-anshuman.khandual@arm.com>
This enables ARCH_HAS_VM_GET_PAGE_PROT on the platform and exports standard
vm_get_page_prot() implementation via DECLARE_VM_GET_PAGE_PROT, which looks
up a private and static protection_map[] array. Subsequently all __SXXX and
__PXXX macros can be dropped which are no longer needed.
