From mboxrd@z Thu Jan 1 00:00:00 1970 From: Kees Cook Subject: [PATCH v3 01/29] powerpc: Rename "notes" PT_NOTE to "note" Date: Tue, 29 Oct 2019 14:13:23 -0700 Message-ID: <20191029211351.13243-2-keescook@chromium.org> References: <20191029211351.13243-1-keescook@chromium.org> Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Return-path: In-Reply-To: <20191029211351.13243-1-keescook@chromium.org> List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Sender: "linux-arm-kernel" Errors-To: linux-arm-kernel-bounces+linux-arm-kernel=m.gmane.org@lists.infradead.org To: Borislav Petkov Cc: linux-arch@vger.kernel.org, linux-s390@vger.kernel.org, Michal Simek , linux-ia64@vger.kernel.org, Kees Cook , Arnd Bergmann , Michael Ellerman , Dave Hansen , Segher Boessenkool , linuxppc-dev@lists.ozlabs.org, Heiko Carstens , Yoshinori Sato , Andy Lutomirski , linux-alpha@vger.kernel.org, Rick Edgecombe , Will Deacon , linux-arm-kernel@lists.infradead.org, linux-c6x-dev@linux-c6x.org List-Id: linux-arch.vger.kernel.org The Program Header identifiers are internal to the linker scripts. In preparation for moving the NOTES segment declaration into RO_DATA, standardize the identifier for the PT_NOTE entry to "note" as used by all other architectures that emit PT_NOTE. Note that there was discussion about changing all architectures to use "notes" instead, but I prefer to avoid that at this time. Changing only powerpc is the smallest change to standardize the entire kernel. And while this standardization does use singular "note" for a section that has more than one note in it, this is just an internal identifier. It matches the ELF "PT_NOTE", and is 4 characters (like "text", and "data") for pretty alignment. The more exposed macro, "NOTES", use the more sensible plural wording.
