Documentation: clk: update file names containing referenced structures
Commit 'b09d6d991' removes include/linux/clk-private.h and re-arranges the clock related structures contained in it in different files. The documentation has not been updated accordingly, thus it wasn't anymore consistent. Place the structures referenced by Documentation/clk.txt in the correct files and update their contents to the latest status.

doc-rst: add docutils config file
To stop the sphinx-build on severe errors and exit with an exit code (to stop make) the halt_level must be set. The halt_level can't be set from sphinx, it is a docutils configuration [1].

Documentation: switch to pdflatex for pdf generation
Looks like rst2pdf is not robust enough, especially for large documents. Use recursive make on the Sphinx generated makefile to convert latex to pdf. The ugly detail is that pdf is generated into Documentation/output/latex. Unfortunately, the pdflatex build generates huge amounts of build log noise, and also fails in the end. We'll fix that next.

binfmt_misc for-linus on 20160727
First off, the intention of this pull is to declare that I'll be the binfmt_misc maintainer (mainly on the grounds of you touched it last, it's yours). There's no MAINTAINERS entry, but get_maintainers.pl will now finger me. The update itself is to allow architecture emulation containers to function such that the emulation binary can be housed outside the container itself. The container and fs parts both have acks from relevant experts. The change is user visible. To use the new feature you have to add an F option to your binfmt_misc configuration. However, the existing tools, like systemd-binfmt work with this without modification.

ramoops: use DT reserved-memory bindings
Instead of a ramoops-specific node, use a child node of /reserved-memory. This requires that of_platform_device_create() be explicitly called for the node, though, since "/reserved-memory" does not have its own "compatible" property.

Highlights:
Trond made a change to the server's tcp logic that allows a fast
client to better take advantage of high bandwidth networks, but
may increase the risk that a single client could starve other
clients; a new sunrpc.svc_rpc_per_connection_limit parameter
should help mitigate this in the (hopefully unlikely) event this
becomes a problem in practice.
Tom Haynes added a minimal flex-layout pnfs server, which is of
no use in production for now--don't build it unless you're doing
client testing or further server development.

Merge tag 'nfsd-4.8' of git://linux-nfs.org/~bfields/linux
Pull nfsd updates from Bruce Fields:
"Highlights:
- Trond made a change to the server's tcp logic that allows a fast
client to better take advantage of high bandwidth networks, but may
increase the risk that a single client could starve other clients;
a new sunrpc.svc_rpc_per_connection_limit parameter should help
mitigate this in the (hopefully unlikely) event this becomes a
problem in practice.
- Tom Haynes added a minimal flex-layout pnfs server, which is of no
use in production for now--don't build it unless you're doing
client testing or further server development"

DocBook: use DOCBOOKS="" to ignore DocBooks instead of IGNORE_DOCBOOKS=1
Instead of a separate ignore flag, use the obvious DOCBOOKS="" to ignore all DocBook files. This is also in line with the Sphinx build being ignored if a non-empty DOCBOOKS make variable is specified on the make command line. This replaces the IGNORE_DOCBOOKS introduced in commit |

dma-mapping: use unsigned long for dma_attrs
The dma-mapping core and the implementations do not change the DMA
attributes passed by pointer. Thus the pointer can point to const data.
However the attributes do not have to be a bitfield. Instead unsigned
long will do fine:
1. This is just simpler. Both in terms of reading the code and setting
attributes. Instead of initializing local attributes on the stack
and passing pointer to it to dma_set_attr(), just set the bits.
2. It brings safeness and checking for const correctness because the
attributes are passed by value.

modules: Add kernel parameter to blacklist modules
Blacklisting a module in linux has long been a problem. The current procedure is to use rd.blacklist=module_name, however, that doesn't cover the case after the initramfs and before a boot prompt (where one is supposed to use /etc/modprobe.d/blacklist.conf to blacklist runtime loading). Using rd.shell to get an early prompt is hit-or-miss, and doesn't cover all situations AFAICT. This patch adds this functionality of permanently blacklisting a module by its name via the kernel parameter module_blacklist=module_name. [v2]: Rusty, use core_param() instead of __setup() which simplifies things. [v3]: Rusty, undo wreckage from strsep() [v4]: Rusty, simpler version of blacklisted() Signed-off-by: Prarit Bhargava <prarit@redhat.com> Cc: Jonathan Corbet <corbet@lwn.net> Cc: Rusty Russell <rusty@rustcorp.com.au> Cc: linux-doc@vger.kernel.org Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> |

orangefs: kernel side caching and executable bugfix
This allows OrangeFS to utilize the dcache and adds an in kernel attribute cache. We previously used the user side client for this purpose. We see a modest performance increase on small file operations. For example, without the cache, compiling coreutils takes about 17 minutes. With the patch and a 50 millisecond timeout for dcache_timeout_msecs and getattr_timeout_msecs (the default), compiling coreutils takes about 6 minutes 20 seconds. On the same hardware, compiling coreutils on an xfs filesystem takes 90 seconds. We see similar improvements with mdtest and a test involving writing, reading, and deleting a large number of small files. Interested parties can review more data at the following URL. https://docs.google.com/spreadsheets/d/1v4aUeppKexIbRMz_Yn9k4eaM3uy2KCaPoe_93YKWOtA/pubhtml The eventual goal of this is to allow getdents to turn into a readdirplus to the OrangeFS server. The cache will be filled then, which should provide a performance benefit to the common case of readdir followed by getattr on each entry (i.e. ls -l). This also fixes a bug. When orangefs_inode_permission was added, it did not collect i_size from the OrangeFS server, since this presses an unnecessary load on the OrangeFS server. However, it left a case where i_size is never initialized. Then running an executable could fail. With this patch, size is always collected to be inserted into the cache. Thus the bug disappears. If this patch is not accepted during this merge window, we will send a one-line band-aid for this bug instead. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIxBAABCAAbBQJXoPhPFBxtYXJ0aW5Ab21uaWJvbmQuY29tAAoJEPVzxHxs4+kh wCsQALUKnyoJzhHAmEoxYZGUPchgBS2yyWQJGP3ViqE8GbVubVG2NsLbluO1u5en /pdOPDXeij7pPGzdWk6wt0tXvM3oGJ3UPRi9ofEtU3XHnb4srX6XHBeG3ZHHZH0A 91NPnMsmlBQvivBbVbjYrgXMKXz/UCQot7Y5iP7o9Gmick5tQqhRB21GcSCMeD7k ycrl61EA+GYDZOlzVspF2LJ52MhIXuT1T9ev66dLQWv8p6pMmpA4kda3Dwvqn/cE GGTeElq2PBGdhGapK4axGfRAW55997j9k6gcxLvFdA99ayAQ3+0hzXw4rNzcdabA ESUOe4riaYEaGEd686Mtd2w9hxvr1bOqkyRCKNnko90JJnqfGsgLfetpasG8CgUo n8VGxjimuCamBDf1+0ZzUs0Pj8q+U1QNQtHJi9QR/sNnNds/52k9OXV2r4MG+suU MAie5eD0Py6GzP9pOrAmuFbBkgd7Ag3EbiTjR1lKRpBR626inL/jM60XFfaF4P5g YOXC+VtJuVR88emIxqJ9ebdEy9+2yfkyinrLH9xZNctoz7KIoMhsmWb2bONKJDnx ngoqVKyH5opw6dKRkbTCM1A2mq8NntDvU6yeyHYJ2NXPXgARf9rSUIJ0RvR3oxdh Fqt5QyYHYDPZBuQn9XUV7t+VhAOFCbAPUDMMlifZUNx7icbj =rGmf -----END PGP SIGNATURE----- Merge tag 'for-linus-v4.8' of git://github.com/martinbrandenburg/linux Pull orangefs update from Martin Brandenburg: "Kernel side caching and executable bugfix This allows OrangeFS to utilize the dcache and adds an in kernel attribute cache.

rapidio: add RapidIO channelized messaging driver
Add channelized messaging driver to support native RapidIO messaging exchange between multiple senders/recipients on devices that use kernel RapidIO subsystem services. This device driver is the result of collaboration within the RapidIO.org Software Task Group (STG) between Texas Instruments, Prodrive Technologies, Nokia Networks, BAE and IDT. Additional input was received from other members of RapidIO.org. The objective was to create a character mode driver interface which exposes messaging capabilities of RapidIO endpoint devices (mports) directly to applications, in a manner that allows the numerous and varied RapidIO implementations to interoperate.

nilfs2: move ioctl interface and disk layout to uapi separately
The header file "include/linux/nilfs2_fs.h" is composed of parts for ioctl and disk format, and both are intended to be shared with user space programs. This moves them to the uapi directory "include/uapi/linux" splitting the file to "nilfs2_api.h" and "nilfs2_ondisk.h". The following minor changes are accompanied by this migration: - nilfs_direct_node struct in nilfs2/direct.h is converged to nilfs2_ondisk.h because it's an on-disk structure. - inline functions nilfs_rec_len_from_disk() and nilfs_rec_len_to_disk() are moved to nilfs2/dir.c.

printk: add kernel parameter to control writes to /dev/kmsg
Add a "printk.devkmsg" kernel command line parameter which controls how userspace writes into /dev/kmsg. It has three options: * ratelimit - ratelimit logging from userspace. * on - unlimited logging from userspace * off - logging from userspace gets ignored The default setting is to ratelimit the messages written to it. This changes the kernel default setting of "on" to "ratelimit" and we do that because we want to keep userspace spamming /dev/kmsg to sane levels. This is especially moot when a small kernel log buffer wraps around and messages get lost. So the ratelimiting setting should be a sane setting where kernel messages should have a bit higher chance of survival from all the spamming. It additionally does not limit logging to /dev/kmsg while the system is booting if we haven't disabled it on the command line. Furthermore, we can control the logging from a lower priority sysctl interface - kernel.printk_devkmsg. That interface will succeed only if printk.devkmsg *hasn't* been supplied on the command line. If it has, then printk.devkmsg is a one-time setting which remains for the duration of the system lifetime. This "locking" of the setting is to prevent userspace from changing the logging on us through sysctl(2). This patch is based on previous patches from Linus and Steven.

- ARM: GICv3 ITS emulation and various fixes. Removal of the old
VGIC implementation. - s390: support for trapping software breakpoints, nested virtualization (vSIE), the STHYI opcode, initial extensions for CPU model support. - MIPS: support for MIPS64 hosts (32-bit guests only) and lots of cleanups, preliminary to this and the upcoming support for hardware virtualization extensions. - x86: support for execute-only mappings in nested EPT; reduced vmexit latency for TSC deadline timer (by about 30%) on Intel hosts; support for more than 255 vCPUs. - PPC: bugfixes. The ugly bit is the conflicts. A couple of them are simple conflicts due to 4.7 fixes, but most of them are with other trees. There was definitely too much reliance on Acked-by here. Some conflicts are for KVM patches where _I_ gave my Acked-by, but the worst are for this pull request's patches that touch files outside arch/*/kvm. KVM submaintainers should probably learn to synchronize better with arch maintainers, with the latter providing topic branches whenever possible instead of Acked-by. This is what we do with arch/x86. And I should learn to refuse pull requests when linux-next sends scary signals, even if that means that submaintainers have to rebase their branches. Anyhow, here's the list: - arch/x86/kvm/vmx.c: handle_pcommit and EXIT_REASON_PCOMMIT was removed by the nvdimm tree. This tree adds handle_preemption_timer and EXIT_REASON_PREEMPTION_TIMER at the same place. In general all mentions of pcommit have to go. There is also a conflict between a stable fix and this patch, where the stable fix removed the vmx_create_pml_buffer function and its call. - virt/kvm/kvm_main.c: kvm_cpu_notifier was removed by the hotplug tree. This tree adds kvm_io_bus_get_dev at the same place. - virt/kvm/arm/vgic.c: a few final bugfixes went into 4.7 before the file was completely removed for 4.8. - include/linux/irqchip/arm-gic-v3.h: this one is entirely our fault; this is a change that should have gone in through the irqchip tree and pulled by kvm-arm. I think I would have rejected this kvm-arm pull request. The KVM version is the right one, except that it lacks GITS_BASER_PAGES_SHIFT. - arch/powerpc: what a mess. For the idle_book3s.S conflict, the KVM tree is the right one; everything else is trivial. In this case I am not quite sure what went wrong. The commit that is causing the mess ( |
