Pull s390 updates from Martin Schwidefsky:
"The most notable change for this pull request is the ftrace rework
from Heiko. It brings a small performance improvement and the ground
work to support a new gcc option to replace the mcount blocks with a
single nop.Two new s390 specific system calls are added to emulate user space
mmio for PCI, an artifact of the how PCI memory is accessed.Two patches for the memory management with changes to common code.
For KVM mm_forbids_zeropage is added which disables the empty zero
page for an mm that is used by a KVM process. And an optimization,
pmdp_get_and_clear_full is added analog to ptep_get_and_clear_full.Some micro optimization for the cmpxchg and the spinlock code.

Checkpatch flags CamelCase identifiers in strict mode, but it has a
feature to ignore parts with only two characters to allow for SI units
like mV or uA. Unfortunately, not all SI units fit in two characters, and
not all are lower case followed by upper case.This patch adds hardcoded detection for frequency and 1024-based size
units (Hz/KHz/MHz/GHz/THz and KiB/MiB/GiB/TiB), since allowing any three
character combinations might be too lenient. The list can later be
expanded as needed.Signed-off-by: Julius Werner

The change from \d+ to .+ inside __aligned() means that the following
structure:struct test {
u8 a __aligned(2);
u8 b __aligned(2);
};essentially gets modified to
struct test {
u8 a;
};for purposes of kernel-doc, thus dropping a struct member, which in
turns causes warnings and invalid kernel-doc generation.Fix this by replacing the catch-all (".") with anything that's not a
semicolon ("[^;]").Fixes: 9dc30918b23f ("scripts/kernel-doc: handle struct member __aligned without numbers")

This patch improves the detection of defects by updating the
regular expression to find Kconfig identifiers in the source
code, and fixes some cases of false positives. The following
changes are made:
- improve regex to find Kconfig identifiers in the source
- exclude .log files from analysis
- improve filtering of false positives (e.g, CONFIG_XXX)
- change output format from (feature:\tlist) to (feature\tlist)Signed-off-by: Valentin Rothberg

The scripts/checkkconfigsymbols.sh script searches Kconfig features
in the source code that are not defined in Kconfig. Such identifiers
always evaluate to false and are the source of various kinds of bugs.
However, the shell script is slow and it does not detect such broken
references in Kbuild and Kconfig files (e.g., ``depends on UNDEFINED´´).
Furthermore, it generates false positives. The script is also hard to
read and understand, and is thereby difficult to maintain.This patch replaces the shell script with an implementation in Python,
which:
(a) detects the same bugs, but does not report previous false positives
(b) additionally detects broken references in Kconfig and all
non-Kconfig files, such as Kbuild, .[cSh], .txt, .sh, defconfig, etc.
(c) is up to 75 times faster than the shell script
(d) only checks files under version controlThe new script reduces the runtime on my machine (i7-2620M, 8GB RAM, SSD)
from 3m47s to 0m3s, and reports 938 broken references in Linux v3.17-rc1;
419 additional reports of which 16 are located in Kconfig files,
287 in defconfigs, 63 in ./Documentation, 1 in Kbuild.Moreover, we intentionally include references in comments, which have been
ignored until now. Such comments may be leftovers of features that have
been removed or renamed in Kconfig (e.g., ``#endif /* CONFIG_MPC52xx */´´).
These references can be misleading and should be removed or replaced.Note that the output format changed from (file list feature) to
(feature file list) as it simplifies the detection of the Kconfig
feature for long file lists.Signed-off-by: Valentin Rothberg

If the function tracer is enabled, allow to set kprobes on the first
instruction of a function (which is the function trace caller):If no kprobe is set handling of enabling and disabling function tracing
of a function simply patches the first instruction. Either it is a nop
(right now it's an unconditional branch, which skips the mcount block),
or it's a branch to the ftrace_caller() function.If a kprobe is being placed on a function tracer calling instruction
we encode if we actually have a nop or branch in the remaining bytes
after the breakpoint instruction (illegal opcode).
This is possible, since the size of the instruction used for the nop
and branch is six bytes, while the size of the breakpoint is only
two bytes.
Therefore the first two bytes contain the illegal opcode and the last
four bytes contain either "0" for nop or "1" for branch. The kprobes
code will then execute/simulate the correct instruction.Instruction patching for kprobes and function tracer is always done
with stop_machine(). Therefore we don't have any races where an
instruction is patched concurrently on a different cpu.
Besides that also the program check handler which executes the function
trace caller instruction won't be executed concurrently to any
stop_machine() execution.This allows to keep full fault based kprobes handling which generates
correct pt_regs contents automatically.Signed-off-by: Heiko Carstens
