+From: Anthony G. Basile <blueness@gentoo.org>
+
+This patch adds support for a restricted user-controlled namespace on
+tmpfs filesystem used to house PaX flags.  The namespace must be of the
+form user.pax.* and its value cannot exceed a size of 8 bytes.
+
+This is needed even on all Gentoo systems so that XATTR_PAX flags
+are preserved for users who might build packages using portage on
+a tmpfs system with a non-hardened kernel and then switch to a
+hardened kernel with XATTR_PAX enabled.
+
+The namespace is added to any user with Extended Attribute support
+enabled for tmpfs.  Users who do not enable xattrs will not have
+the XATTR_PAX flags preserved.

+FEATURES
+This patch adds additional CPU options to the Linux kernel accessible under:
+ Processor type and features  --->
+  Processor family --->
+
+With the release of gcc 11.1 and clang 12.0, several generic 64-bit levels are
+offered which are good for supported Intel or AMD CPUs:
+• x86-64-v2
+• x86-64-v3
+• x86-64-v4
+
+Users of glibc 2.33 and above can see which level is supported by current
+hardware by running:
+  /lib/ld-linux-x86-64.so.2 --help | grep supported
+
+Alternatively, compare the flags from /proc/cpuinfo to this list.[1]
+
+CPU-specific microarchitectures include:
+• AMD Improved K8-family
+• AMD K10-family
+• AMD Family 10h (Barcelona)
+• AMD Family 14h (Bobcat)
+• AMD Family 16h (Jaguar)

+Notes: If not otherwise noted, gcc >=9.1 is required for support.
+       *Requires gcc >=10.1 or clang >=10.0
+       †Required gcc >=10.3 or clang >=12.0
+       ‡Required gcc >=11.1 or clang >=12.0
+       §Required gcc >=13.0 or clang >=15.0.5
+
+It also offers to compile passing the 'native' option which, "selects the CPU
+to generate code for at compilation time by determining the processor type of
+the compiling machine. Using -march=native enables all instruction subsets
+supported by the local machine and will produce code optimized for the local
+machine under the constraints of the selected instruction set."[2]
+
+Users of Intel CPUs should select the 'Intel-Native' option and users of AMD
+CPUs should select the 'AMD-Native' option.
+
+MINOR NOTES RELATING TO INTEL ATOM PROCESSORS
+This patch also changes -march=atom to -march=bonnell in accordance with the
+gcc v4.9 changes. Upstream is using the deprecated -match=atom flags when I
+believe it should use the newer -march=bonnell flag for atom processors.[3]
+
+It is not recommended to compile on Atom-CPUs with the 'native' option.[4] The
+recommendation is to use the 'atom' option instead.
+
+BENEFITS
+Small but real speed increases are measurable using a make endpoint comparing
+a generic kernel to one built with one of the respective microarchs.
