PR bin/60099 - Fix unquoted $* ($@) expansion
Make unquoted $* (or $@) when used in a context where field
splitting happens (which requires unquoted of course) generate
the same result, always, as would have been obtained had the
number of params been known, and
$1 $2 $3 ... ${n} (n is the value of $#)
been used instead of $* - so for x$*y, for any strings x & y
(including empty), the equivalent would be
x$1 $2 $3 ... ${n}y
This must hold, whatever the setting of IFS (which affects
how the fields generated are field split after they appear,
but should not affect the generation of those fields).
The bug this fixes is (in practice) never encountered, which is
how it has persisted for so long, and in so many different shells.
The method that was previously used to expand $* in this situation
would work perfectly, if the first character of ${IFS} was an IFS

Minor cleanups
Cleanup CTLccc char definitions (layout only):
#define [space|tab] consistency, align value column,
add hex equivalents (in comments) for octal char values
Minor changes to comments.
NFC.
Add DEBUG_ONLY() to include anything in DEBUG code
DEBUG_ONLY(x) expands to its arg, which should not contain commas
(outside parens) only in DEBUG mode compiles, most useful for var
declarations, and similar. Nb: code only, not outside functions.
Some cleanups/additions to comments.
By itself, this is a NFC change (until something uses DEBUG_ONLY()
for DEBUG mode code alteration).
PR lib/60111 - Add some bounds checking
As requested by the PR, bounds checking on the two obvious
places I could see where overflow looks possible has been added.
Detected overflow should generate a decode error.
PR 60119 - don't set -o pipefail (revert previous)
I was going to make the setting of the pipefail option check if
the executing shell supports the option or not (all should really,
and up to date dash does - it is a standard option) - but then I
looked at the script, and couldn't find a pipe used anywhere.
The option is useless here. So, bye-bye pipefail.
[VPlan] Add m_VPPhi pattern matcher and use in removeDeadRecipes (NFC).
Add m_VPPhi to match VPPhi instructions with exactly 2 operands.
Split off from https://github.com/llvm/llvm-project/pull/156262.
Reorder slightly for correctness
The "pipefail" option is now a POSIX standard option, move it
from the extensions section to the standard options section.
The (very fake) "r" option is not a standard option, though it
is a command line only "option" - move it away from -s, -c
the other (but standard) command line only options, and to a
section of its own (our first non-standard command line only option).
NFC - the order of options in this definition file is for human
(those who view this file) purposes only, all is reordered by
mkoptions.sh before being included with the shell sources.
Use sh internal char typing, not <ctype.h>
That is, use the internal shell is_digit() rather than isdigit().
No practical functional change (a digit is a digit).
[llvm][ADT] Add PointerUnion benchmarks. NFC. (#187874)
Add microbenchmarks for `PointerUnion`'s `isa` and `isNull` operations
across union sizes of 2, 4, and 8 types. This it to establish baseline
performance numbers before making changes to the implementation.
I plan to refactor the implementation a bit and add support for more
variants using sparse encoding.

i2c: tegra: Don't mark devices with pins as IRQ safe
I2C devices with associated pinctrl states (DPAUX I2C controllers)
will change pinctrl state during runtime PM. This requires taking
a mutex, so these devices cannot be marked as IRQ safe.
Add PINCTRL as dependency to avoid build errors.

Merge tag 'trace-v7.0-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull tracing fixes from Steven Rostedt:
- Revert "tracing: Remove pid in task_rename tracing output"
A change was made to remove the pid field from the task_rename event
because it was thought that it was always done for the current task
and recording the pid would be redundant. This turned out to be
incorrect and there are a few corner case where this is not true and
caused some regressions in tooling.
- Fix the reading from user space for migration
The reading of user space uses a seq lock type of logic where it uses
a per-cpu temporary buffer and disables migration, then enables
preemption, does the copy from user space, disables preemption,
enables migration and checks if there was any schedule switches while
preemption was enabled. If there was a context switch, then it is
