arch/*/configs/*defconfig: Replace AUTOFS4_FS by AUTOFS_FS Commit a2225d931f75 ("autofs: remove left-over autofs4 stubs") promised the removal of the fs/autofs/Kconfig fragment for AUTOFS4_FS within a couple of releases, but five years later this still has not happened yet, and AUTOFS4_FS is still enabled in 63 defconfigs. Get rid of it mechanically: git grep -l CONFIG_AUTOFS4_FS -- '*defconfig' | xargs sed -i 's/AUTOFS4_FS/AUTOFS_FS/' Also just remove the AUTOFS4_FS config option stub. Anybody who hasn't regenerated their config file in the last five years will need to just get the new name right when they do.

efi: vars: Remove deprecated 'efivars' sysfs interface Commit 5d9db883761a ("efi: Add support for a UEFI variable filesystem") dated Oct 5, 2012, introduced a new efivarfs pseudo-filesystem to replace the efivars sysfs interface that was used up to that point to expose EFI variables to user space. The main problem with the sysfs interface was that it only supported up to 1024 bytes of payload per file, whereas the underlying variables themselves are only bounded by a platform specific per-variable and global limit that is typically much higher than 1024 bytes. The deprecated sysfs interface is only enabled on x86 and Itanium, other EFI enabled architectures only support the efivarfs pseudo-filesystem. So let's finally rip off the band aid, and drop the old interface entirely. This will make it easier to refactor and clean up the underlying infrastructure that is shared between efivars, efivarfs and efi-pstore, and is long overdue for a makeover.

vgacon: remove software scrollback support Yunhai Zhang recently fixed a VGA software scrollback bug in commit ebfdfeeae8c0 ("vgacon: Fix for missing check in scrollback handling"), but that then made people look more closely at some of this code, and there were more problems on the vgacon side, but also the fbcon software scrollback. We don't really have anybody who maintains this code - probably because nobody actually _uses_ it any more. Sure, people still use both VGA and the framebuffer consoles, but they are no longer the main user interfaces to the kernel, and haven't been for decades, so these kinds of extra features end up bitrotting and not really being used. So rather than try to maintain a likely unused set of code, I'll just aggressively remove it, and see if anybody even notices. Maybe there are people who haven't jumped on the whole GUI badnwagon yet, and think it's just a fad. And maybe those people use the scrollback code. If that turns out to be the case, we can resurrect this again, once we've found the sucker^Wmaintainer for it who actually uses it.

The logic behind the quirks is always built into the sr driver. This also removes the config from all the defconfig files that are enabling this already.

Having it enabled generates a faster kernel at very little extra cost since we already include all the code patching code by having KPROBES enabled.

x86/build/defconfig: Enable USB_EHCI_TT_NEWSCHED=y Some Gentoo users are encountering problems because USB_EHCI_TT_NEWSCHED isn't set in the defconfig (and Gentoo differs from other distros in not providing a distro .config). Alan Stern has said there's no reason to not set it, and the ability to turn it off at all should probably be yanked: http://article.gmane.org/gmane.linux.usb.general/119920 This addresses issue: https://bugs.gentoo.org/show_bug.cgi?id=533472 (The problem also theoretically affects the sh, arm, mips, powerpc, and sparc archs, but those would be other patches if this one that fixes 98% of the problem is accepted).

cgroup: remove the ns_cgroup The ns_cgroup is an annoying cgroup at the namespace / cgroup frontier and leads to some problems: * cgroup creation is out-of-control * cgroup name can conflict when pids are looping * it is not possible to have a single process handling a lot of namespaces without falling in a exponential creation time * we may want to create a namespace without creating a cgroup The ns_cgroup was replaced by a compatibility flag 'clone_children', where a newly created cgroup will copy the parent cgroup values. The userspace has to manually create a cgroup and add a task to the 'tasks' file. This patch removes the ns_cgroup as suggested in the following thread: https://lists.linux-foundation.org/pipermail/containers/2009-June/018616.html The 'cgroup_clone' function is removed because it is no longer used. This is a userspace-visible change. Commit 45531757b45c ("cgroup: notify ns_cgroup deprecated") (merged into 2.6.27) caused the kernel to emit a printk warning users that the feature is planned for removal.

x86, hwmon: Package Level Thermal/Power: pkgtemp hwmon driver This patch adds a hwmon driver for package level thermal control. The driver dumps package level thermal information through sysfs interface so that upper level application (e.g. lm_sensor) can retrive the information. Instead of having the package level hwmon code in coretemp, I write a seperate driver pkgtemp because: First, package level thermal sensors include not only sensors for each core, but also sensors for uncore, memory controller or other components in the package. Logically it will be clear to have a seperate hwmon driver for package level hwmon to monitor wider range of sensors in a package. Merging package thermal driver into core thermal driver doesn't make sense and may mislead. Secondly, merging the two drivers together may cause coding mess. It's easier to include various package level sensors info if more sensor information is implemented. Coretemp code needs to consider a lot of legacy machine cases. Pkgtemp code only considers platform starting from Sandy Bridge. On a 1Sx4Cx2T Sandy Bridge platform, lm-sensors dumps the pkgtemp and coretemp: pkgtemp-isa-0000 Adapter: ISA adapter physical id 0: +33.0°C (high = +79.0°C, crit = +99.0°C) coretemp-isa-0000 Adapter: ISA adapter Core 0: +32.0°C (high = +79.0°C, crit = +99.0°C) coretemp-isa-0001 Adapter: ISA adapter Core 1: +32.0°C (high = +79.0°C, crit = +99.0°C) coretemp-isa-0002 Adapter: ISA adapter Core 2: +32.0°C (high = +79.0°C, crit = +99.0°C) coretemp-isa-0003 Adapter: ISA adapter Core 3: +32.0°C (high = +79.0°C, crit = +99.0°C) [ hpa: folded v3 patch removing improper global variable "SHOW" ] Signed-off-by: Fenghua Yu <fenghua.yu@intel.com> LKML-Reference: <1280448826-12004-3-git-send-email-fenghua.yu@intel.com> Reviewed-by: Len Brown <len.brown@intel.com> Signed-off-by: H.

x86: remove the Voyager 32-bit subarch Impact: remove unused/broken code The Voyager subarch last built successfully on the v2.6.26 kernel and has been stale since then and does not build on the v2.6.27, v2.6.28 and v2.6.29-rc5 kernels. No actual users beyond the maintainer reported this breakage. Patches were sent and most of the fixes were accepted but the discussion around how to do a few remaining issues cleanly fizzled out with no resolution and the code remained broken. In the v2.6.30 x86 tree development cycle 32-bit subarch support has been reworked and removed - and the Voyager code, beyond the build problems already known, needs serious and significant changes and probably a rewrite to support it. CONFIG_X86_VOYAGER has been marked BROKEN then. The maintainer has been notified but no patches have been sent so far to fix it. While all other subarchs have been converted to the new scheme, voyager is still broken. We'd prefer to receive patches which clean up the current situation in a constructive way, but even in case of removal there is no obstacle to add that support back after the issues have been sorted out in a mutually acceptable fashion. So remove this inactive code for now. Signed-off-by: Ingo Molnar <mingo@elte.hu>

x86: merge winchip-2 and winchip-2a cpu choices The Winchip-2 and Winchip-2A cpu choices select the same options for kernel and compiler. Merge them to save few bytes and reduce confusion.

x86: additional defconfig updates Additional updates to the x86 defconfigs. The goals are, as before: - Make them usable to testers, more so than distributors or end users, both of which are likely to have their own config already. - Keep 32 and 64 bits as similar as is practical. Changes: - Use a more generic CPU type (ppro and generic, respectively). - Bump number of CPUs to 64 (few if any NR_CPUS arrays left). - Enable PAT. - Enable OPTIMIZE_INLINE. - Enable microcode update support. - Build SMT scheduler support (in addition to MC).

x86 setup: remove remnants of CONFIG_VIDEO_SELECT (read: vga=) Impact: cleanup Video mode selection became always possible in 2.6.23-rc1 after i386 setup code rewrite in C. Regardless, VIDEO_SELECT is stupid config option because it affects only kernel setup code, not code which always stays in memory. vga= always possible now which is good.

Subject: devmem, x86: fix rename of CONFIG_NONPROMISC_DEVMEM From: Arjan van de Ven <arjan@infradead.org> Date: Sat, 19 Jul 2008 15:47:17 -0700 CONFIG_NONPROMISC_DEVMEM was a rather confusing name - but renaming it to CONFIG_PROMISC_DEVMEM causes problems on architectures that do not support this feature; this patch renames it to CONFIG_STRICT_DEVMEM, so that architectures can opt-in into it. ( the polarity of the option is still the same as it was originally; it needs to be for now to not break architectures that don't have the infastructure yet to support this feature) Signed-off-by: Arjan van de Ven <arjan@linux.intel.com> Cc: "V.Radhakrishnan" <rk@atr-labs.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> ---

x86: add optimized inlining add CONFIG_OPTIMIZE_INLINING=y. allow gcc to optimize the kernel image's size by uninlining functions that have been marked 'inline'. Previously gcc was forced by Linux to always-inline these functions via a gcc attribute: #define inline inline __attribute__((always_inline)) Especially when the user has already selected CONFIG_OPTIMIZE_FOR_SIZE=y this can make a huge difference in kernel image size (using a standard Fedora .config): text data bss dec hex filename 5613924 562708 3854336 10030968 990f78 vmlinux.before 5486689 562708 3854336 9903733 971e75 vmlinux.after that's a 2.3% text size reduction (!).

x86: 64-bit, make sparsemem vmemmap the only memory model Use sparsemem as the only memory model for UP, SMP and NUMA. Measurements indicate that DISCONTIGMEM has a higher overhead than sparsemem. And FLATMEMs benefits are minimal. So I think its best to simply standardize on sparsemem. Results of page allocator tests (test can be had via git from slab git tree branch tests) Measurements in cycle counts. 1000 allocations were performed and then the average cycle count was calculated.

x86: move defconfig files for i386 and x86_64 to x86 With some small changes to kconfig makefile we can now locate the defconfig files for i386 and x86_64 in the configs/ subdirectory under x86. make ARCH=i386 defconfig and make defconfig works as expected also after this change. But arch maintainers shall now update a defconfig file in the configs/ directory. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
