+From: Anthony G. Basile <blueness@g.o>
+
+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.

++What is it?
++-----------
++
++The framebuffer decorations are a kernel feature which allows displaying a
++background picture on selected consoles.
++
++What do I need to get it to work?
++---------------------------------
++
++To get fbcondecor up-and-running you will have to:
++ 1) get a copy of splashutils [1] or a similar program
++ 2) get some fbcondecor themes
++ 3) build the kernel helper program
++ 4) build your kernel with the FB_CON_DECOR option enabled.
++
++To get fbcondecor operational right after fbcon initialization is finished, you
++will have to include a theme and the kernel helper into your initramfs image.
++Please refer to splashutils documentation for instructions on how to do that.
++
++[1] The splashutils package can be downloaded from:
++    http://github.com/alanhaggai/fbsplash
++
++The userspace helper
++--------------------
++
++The userspace fbcondecor helper (by default: /sbin/fbcondecor_helper) is called by the
++kernel whenever an important event occurs and the kernel needs some kind of
++job to be carried out. Important events include console switches and video
++mode switches (the kernel requests background images and configuration
++parameters for the current console). The fbcondecor helper must be accessible at
++all times. If it's not, fbcondecor will be switched off automatically.
++
++It's possible to set path to the fbcondecor helper by writing it to
++/proc/sys/kernel/fbcondecor.
++
++*****************************************************************************
++
++The information below is mostly technical stuff. There's probably no need to
++read it unless you plan to develop a userspace helper.
++
++The fbcondecor protocol
++-----------------------
++
++The fbcondecor protocol defines a communication interface between the kernel and
++the userspace fbcondecor helper.
++
++The kernel side is responsible for:
++
++ * rendering console text, using an image as a background (instead of a
++   standard solid color fbcon uses),
++ * accepting commands from the user via ioctls on the fbcondecor device,
++ * calling the userspace helper to set things up as soon as the fb subsystem
++   is initialized.
++
++The userspace helper is responsible for everything else, including parsing
++configuration files, decompressing the image files whenever the kernel needs
++it, and communicating with the kernel if necessary.
++
++The fbcondecor protocol specifies how communication is done in both ways:
++kernel->userspace and userspace->helper.
++
++Kernel -> Userspace
++-------------------
++
++The kernel communicates with the userspace helper by calling it and specifying
++the task to be done in a series of arguments.
++
++The arguments follow the pattern:
++<fbcondecor protocol version> <command> <parameters>
++
++All commands defined in fbcondecor protocol v2 have the following parameters:
++ virtual console
++ framebuffer number
++ theme
++
++Fbcondecor protocol v1 specified an additional 'fbcondecor mode' after the
++framebuffer number. Fbcondecor protocol v1 is deprecated and should not be used.
++
++Fbcondecor protocol v2 specifies the following commands:
++
++getpic
++------
++ The kernel issues this command to request image data. It's up to the
++ userspace  helper to find a background image appropriate for the specified
++ theme and the current resolution. The userspace helper should respond by
++ issuing the FBIOCONDECOR_SETPIC ioctl.
++
++init
++----
++ The kernel issues this command after the fbcondecor device is created and
++ the fbcondecor interface is initialized. Upon receiving 'init', the userspace
++ helper should parse the kernel command line (/proc/cmdline) or otherwise
++ decide whether fbcondecor is to be activated.
++
++ To activate fbcondecor on the first console the helper should issue the
++ FBIOCONDECOR_SETCFG, FBIOCONDECOR_SETPIC and FBIOCONDECOR_SETSTATE commands,
++ in the above-mentioned order.
++
++ When the userspace helper is called in an early phase of the boot process
++ (right after the initialization of fbcon), no filesystems will be mounted.
++ The helper program should mount sysfs and then create the appropriate
++ framebuffer, fbcondecor and tty0 devices (if they don't already exist) to get
++ current display settings and to be able to communicate with the kernel side.
++ It should probably also mount the procfs to be able to parse the kernel
++ command line parameters.
++
++ Note that the console sem is not held when the kernel calls fbcondecor_helper
++ with the 'init' command. The fbcondecor helper should perform all ioctls with
++ origin set to FBCON_DECOR_IO_ORIG_USER.
++
++modechange
++----------
++ The kernel issues this command on a mode change. The helper's response should
++ be similar to the response to the 'init' command. Note that this time the
++ console sem is held and all ioctls must be performed with origin set to
++ FBCON_DECOR_IO_ORIG_KERNEL.
++
++
++Userspace -> Kernel
++-------------------
++
++Userspace programs can communicate with fbcondecor via ioctls on the
++fbcondecor device. These ioctls are to be used by both the userspace helper
++(called only by the kernel) and userspace configuration tools (run by the users).
++
++The fbcondecor helper should set the origin field to FBCON_DECOR_IO_ORIG_KERNEL
++when doing the appropriate ioctls. All userspace configuration tools should
++use FBCON_DECOR_IO_ORIG_USER. Failure to set the appropriate value in the origin
++field when performing ioctls from the kernel helper will most likely result
++in a console deadlock.
++
++FBCON_DECOR_IO_ORIG_KERNEL instructs fbcondecor not to try to acquire the console
++semaphore. Not surprisingly, FBCON_DECOR_IO_ORIG_USER instructs it to acquire
++the console sem.
++
++The framebuffer console decoration provides the following ioctls (all defined in
++linux/fb.h):
++
++FBIOCONDECOR_SETPIC
++description: loads a background picture for a virtual console
++argument: struct fbcon_decor_iowrapper*; data: struct fb_image*
++notes:
++If called for consoles other than the current foreground one, the picture data
++will be ignored.
++
++If the current virtual console is running in a 8-bpp mode, the cmap substruct
++of fb_image has to be filled appropriately: start should be set to 16 (first
++16 colors are reserved for fbcon), len to a value <= 240 and red, green and
++blue should point to valid cmap data. The transp field is ingored. The fields
++dx, dy, bg_color, fg_color in fb_image are ignored as well.
++
++FBIOCONDECOR_SETCFG
++description: sets the fbcondecor config for a virtual console
++argument: struct fbcon_decor_iowrapper*; data: struct vc_decor*
++notes: The structure has to be filled with valid data.
++
++FBIOCONDECOR_GETCFG
++description: gets the fbcondecor config for a virtual console
++argument: struct fbcon_decor_iowrapper*; data: struct vc_decor*
++
++FBIOCONDECOR_SETSTATE
++description: sets the fbcondecor state for a virtual console
++argument: struct fbcon_decor_iowrapper*; data: unsigned int*
++          values: 0 = disabled, 1 = enabled.
++
++FBIOCONDECOR_GETSTATE
++description: gets the fbcondecor state for a virtual console
++argument: struct fbcon_decor_iowrapper*; data: unsigned int*
++          values: as in FBIOCONDECOR_SETSTATE
++
++Info on used structures:
++
++Definition of struct vc_decor can be found in linux/console_decor.h. It's
++heavily commented. Note that the 'theme' field should point to a string
++no longer than FBCON_DECOR_THEME_LEN. When FBIOCONDECOR_GETCFG call is
++performed, the theme field should point to a char buffer of length
++FBCON_DECOR_THEME_LEN.
++
++Definition of struct fbcon_decor_iowrapper can be found in linux/fb.h.
++The fields in this struct have the following meaning:
++
++vc:
++Virtual console number.
++
++origin:

++       bool "Configure UAC policy via sysctl"
++       depends on SYSCTL
++       default y
++       ---help---
++         Configuring the UAC (unaligned access control) policy on a Linux
++         system usually involves setting a compile time define. If you say
++         Y here, you will be able to modify the UAC policy at runtime using
++         the /proc interface.
++
++         The UAC policy defines the action Linux should take when an
++         unaligned memory access occurs. The action can include printing a
++         warning message (NOPRINT), sending a signal to the offending
++         program to help developers debug their applications (SIGBUS), or
++         disabling the transparent fixing (NOFIX).
++
++         The sysctls will be initialized to the compile-time defined UAC
++         policy. You can change these manually, or with the sysctl(8)
++         userspace utility.
++
++         To disable the warning messages at runtime, you would use
++
++           echo 1 > /proc/sys/kernel/uac/noprint
++
++         This is pretty harmless. Say Y if you're not sure.

+WARNING
+This patch works with gcc versions 4.9+ and with kernel version 4.13+ and should
+NOT be applied when compiling on older versions of gcc due to key name changes
+of the march flags introduced with the version 4.9 release of gcc.[1]
+
+Use the older version of this patch hosted on the same github for older
+versions of gcc.
+
+FEATURES
+This patch adds additional CPU options to the Linux kernel accessible under:
+ Processor type and features  --->
+  Processor family --->
+
+The expanded microarchitectures include:
+* AMD Improved K8-family
+* AMD K10-family
+* AMD Family 10h (Barcelona)
+* AMD Family 14h (Bobcat)
+* AMD Family 16h (Jaguar)
+* AMD Family 15h (Bulldozer)
+* AMD Family 15h (Piledriver)
+* AMD Family 15h (Steamroller)
+* AMD Family 15h (Excavator)
+* AMD Family 17h (Zen)
+* Intel Silvermont low-power processors
+* Intel 1st Gen Core i3/i5/i7 (Nehalem)
+* Intel 1.5 Gen Core i3/i5/i7 (Westmere)
+* Intel 2nd Gen Core i3/i5/i7 (Sandybridge)
+* Intel 3rd Gen Core i3/i5/i7 (Ivybridge)
+* Intel 4th Gen Core i3/i5/i7 (Haswell)
+* Intel 5th Gen Core i3/i5/i7 (Broadwell)
+* Intel 6th Gen Core i3/i5/i7 (Skylake)
+* Intel 6th Gen Core i7/i9 (Skylake X)
+
+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."[3]
+
+MINOR NOTES
+This patch also changes 'atom' to 'bonnell' in accordance with the gcc v4.9
+changes. Note that upstream is using the deprecated 'match=atom' flags when I
+believe it should use the newer 'march=bonnell' flag for atom processors.[2]
+
+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.
+
+See the following experimental evidence supporting this statement:
