locking/atomic/bitops: Document and clarify ordering semantics for failed test_and_{}_bit()
A test_and_{}_bit() operation fails if the value of the bit is such that
the modification does not take place. For example, if test_and_set_bit()
returns 1. In these cases, follow the behaviour of cmpxchg and allow the
operation to be unordered. This also applies to test_and_set_bit_lock()
if the lock is found to be be taken already.

Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull s390 updates from Heiko Carstens:
"The main thing in this merge is the defense for the Spectre
vulnerabilities. But there are other updates as well, the changes in
more detail:
- An s390 specific implementation of the array_index_mask_nospec
function to the defense against spectre v1
- Two patches to utilize the new PPA-12/PPA-13 instructions to run
the kernel and/or user space with reduced branch predicton.
- The s390 variant of the 'retpoline' spectre v2 defense called
'expoline'. There is no return instruction for s390, instead an
indirect branch is used for function return
The s390 defense mechanism for indirect branches works by using an
execute-type instruction with the indirect branch as the target of
the execute. In effect that turns off the prediction for the
indirect branch.
- Scrub registers in entry.S that contain user controlled values to
prevent the speculative use of these values.
- Re-add the second parameter for the s390 specific runtime
instrumentation system call and move the header file to uapi. The
second parameter will continue to do nothing but older kernel
versions only accepted valid real-time signal numbers. The details
will be documented in the man-page for the system call.
- Corrections and improvements for the s390 specific documentation
- Add a line to /proc/sysinfo to display the CPU model dependent
license-internal-code identifier
- A header file include fix for eadm.
- An error message fix in the kprobes code.
- The removal of an outdated ARCH_xxx select statement"
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux:
s390/kconfig: Remove ARCH_WANTS_PROT_NUMA_PROT_NONE select
s390: introduce execute-trampolines for branches
s390: run user space and KVM guests with modified branch prediction
s390: add options to change branch prediction behaviour for the kernel
s390/alternative: use a copy of the facility bit mask
s390: add optimized array_index_mask_nospec
s390: scrub registers on kernel entry and KVM exit
s390/cio: fix kernel-doc usage

original IORT table with a new one from initrd (Prarit Bhargava,
Shunyong Yang).
- Add battery-related quirks for Asus UX360UA and UX410UAK and add
quirks for table parsing on Dell XPS 9570 and Precision M5530

installed, do:
ls /afs/grand.central.org

cpufreq: Add and use cpufreq_for_each_{valid_,}entry_idx()
Pointer subtraction is slow and tedious. Therefore, replace all instances
where cpufreq_for_each_{valid_,}entry loops contained such substractions
with an iteration macro providing an index to the frequency_table entry.

ACPI: SPCR: Make SPCR available to x86
SPCR is currently only enabled or ARM64 and x86 can use SPCR to setup an early console. General fixes include updating Documentation & Kconfig (for x86), updating comments, and changing parse_spcr() to acpi_parse_spcr(), and earlycon_init_is_deferred to earlycon_acpi_spcr_enable to be more descriptive. On x86, many systems have a valid SPCR table but the table version is not 2 so the table version check must be a warning. On ARM64 when the kernel parameter earlycon is used both the early console and console are enabled. On x86, only the earlycon should be enabled by by default. Modify acpi_parse_spcr() to allow options for initializing the early console and console separately.

Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma
Pull more rdma updates from Doug Ledford:
"Items of note:
- two patches fix a regression in the 4.15 kernel. The 4.14 kernel
worked fine with NVMe over Fabrics and mlx5 adapters. That broke in
4.15. The fix is here.
- one of the patches (the endian notation patch from Lijun) looks
like a lot of lines of change, but it's mostly mechanical in
nature. It amounts to the biggest chunk of change in it (it's about
2/3rds of the overall pull request).
Summary:
- Clean up some function signatures in rxe for clarity
- Tidy the RDMA netlink header to remove unimplemented constants
- bnxt_re driver fixes, one is a regression this window.
- Minor hns driver fixes
- Various fixes from Dan Carpenter and his tool
- Fix IRQ cleanup race in HFI1

- Fix for an IPoIB startup sequence race with the external manager
- Oops fix for the new kabi path

afs: Support the AFS dynamic root
Support the AFS dynamic root which is a pseudo-volume that doesn't connect to any server resource, but rather is just a root directory that dynamically creates mountpoint directories where the name of such a directory is the name of the cell. Such a mount can be created thus: mount -t afs none /afs -o dyn Dynamic root superblocks aren't shared except by bind mounts and propagation. Cell root volumes can then be mounted by referring to them by name, e.g.: ls /afs/grand.central.org/ ls /afs/.grand.central.org/ The kernel will upcall to consult the DNS if the address wasn't supplied directly.
