Drop all 00-INDEX files from Documentation/

2018-09-09T21:08:58Z

This is a respin with a wider audience (all that get_maintainer returned) and I know this spams a *lot* of people. Not sure what would be the correct way, so my apologies for ruining your inbox. The 00-INDEX files are supposed to give a summary of all files present in a directory, but these files are horribly out of date and their usefulness is brought into question. Often a simple "ls" would reveal the same information as the filenames are generally quite descriptive as a short introduction to what the file covers (it should not surprise anyone what Documentation/sched/sched-design-CFS.txt covers) A few years back it was mentioned that these files were no longer really needed, and they have since then grown further out of date, so perhaps it is time to just throw them out. A short status yields the following _outdated_ 00-INDEX files, first counter is files listed in 00-INDEX but missing in the directory, last is files present but not listed in 00-INDEX. List of outdated 00-INDEX: Documentation: (4/10) Documentation/sysctl: (0/1) Documentation/timers: (1/0) Documentation/blockdev: (3/1) Documentation/w1/slaves: (0/1) Documentation/locking: (0/1) Documentation/devicetree: (0/5) Documentation/power: (1/1) Documentation/powerpc: (0/5) Documentation/arm: (1/0) Documentation/x86: (0/9) Documentation/x86/x86_64: (1/1) Documentation/scsi: (4/4) Documentation/filesystems: (2/9) Documentation/filesystems/nfs: (0/2) Documentation/cgroup-v1: (0/2) Documentation/kbuild: (0/4) Documentation/spi: (1/0) Documentation/virtual/kvm: (1/0) Documentation/scheduler: (0/2) Documentation/fb: (0/1) Documentation/block: (0/1) Documentation/networking: (6/37) Documentation/vm: (1/3) Then there are 364 subdirectories in Documentation/ with several files that are missing 00-INDEX alltogether (and another 120 with a single file and no 00-INDEX). I don't really have an opinion to whether or not we /should/ have 00-INDEX, but the above 00-INDEX should either be removed or be kept up to date. If we should keep the files, I can try to keep them updated, but I rather not if we just want to delete them anyway. As a starting point, remove all index-files and references to 00-INDEX and see where the discussion is going. Signed-off-by: Henrik Austad Acked-by: "Paul E.

powerpc/dscr: Add documentation for DSCR support

2015-06-07T09:29:27Z

This patch adds a new documentation file explaining the DSCR support on powerpc platforms. This explains DSCR related data structure, code paths and also available user interfaces. Any further functional changes to the DSCR support in the kernel should definitely update the documentation here. Signed-off-by: Anshuman Khandual Signed-off-by: Michael Ellerman

cxl: Add documentation for userspace APIs

2014-10-08T09:16:19Z

This documentation gives an overview of the hardware architecture, userspace APIs via /dev/cxl/afuM.N and the syfs files. It also adds a MAINTAINERS file entry for cxl. Signed-off-by: Ian Munsie Signed-off-by: Michael Neuling Signed-off-by: Michael Ellerman

KVM: PPC: Remove 440 support

2014-07-28T13:23:15Z

The 440 target hasn't been properly functioning for a few releases and before I was the only one who fixes a very serious bug that indicates to me that nobody used it before either. Furthermore KVM on 440 is slow to the extent of unusable. We don't have to carry along completely unused code. Remove 440 and give us one less thing to worry about. Signed-off-by: Alexander Graf

powerpc: Update the 00-Index in Documentation/powerpc

2013-08-27T04:44:27Z

People have been dropping things in here without updating the index, do it for them. Signed-off-by: Michael Ellerman Signed-off-by: Benjamin Herrenschmidt

powerpc/perf: Core EBB support for 64-bit book3s

2013-07-01T01:50:10Z

Add support for EBB (Event Based Branches) on 64-bit book3s. See the included documentation for more details. EBBs are a feature which allows the hardware to branch directly to a specified user space address when a PMU event overflows. This can be used by programs for self-monitoring with no kernel involvement in the inner loop. Most of the logic is in the generic book3s code, primarily to avoid a proliferation of PMU callbacks.

powerpc: remove PReP platform

2013-04-18T03:03:53Z

PPC_PREP is marked as BROKEN since v2.6.15. Remove all PReP specific code now. Signed-off-by: Paul Bolle Signed-off-by: Michael Ellerman

Documentation: add devicetree docs index file

2011-03-16T17:47:03Z

The device tree infrastructure is being genericized so its documentation moved out of the PowerPC directory. Signed-off-by: Rob Landley Signed-off-by: Randy Dunlap Signed-off-by: Linus Torvalds

powerpc: Remove outdated Documentation/powerpc/smp.txt

2008-10-07T03:26:19Z

Documentation/powerpc/smp.txt is so outdated that it makes sense to just remove it. Signed-off-by: Geert Uytterhoeven Signed-off-by: Benjamin Herrenschmidt

powerpc: Remove remains of /proc/ppc_htab

2008-10-07T03:26:19Z

commit 14cf11af6cf608eb8c23e989ddb17a715ddce109 ("powerpc: Merge enough to start building in arch/powerpc.") unwired /proc/ppc_htab, and commit 917f0af9e5a9ceecf9e72537fabb501254ba321d ("powerpc: Remove arch/ppc and include/asm-ppc") removed the rest of the /proc/ppc_htab support, but there are still a few references left. Kill them for good. Signed-off-by: Geert Uytterhoeven Signed-off-by: Benjamin Herrenschmidt
