On architectures with hardware broadcasting of TLB invalidation messages

unmapping page ranges based on the dirty address information passed to

Add a new execveat(2) system call. execveat() is to execve() as
openat() is to open(): it takes a file descriptor that refers to a
directory, and resolves the filename relative to that.
In addition, if the filename is empty and AT_EMPTY_PATH is specified,
execveat() executes the file to which the

Sparc folks: the kbuild robots complained about sparc missing this

However, I've not run it (only cross-compiled it), so it may be best
to skip the [3/4] patch and let the experts deal with other
architectures later

The ARM errata 819472, 826319, 827319 and 824069 define the same
workaround for these hardware issues in certain Cortex-A53 parts.
Use the new alternatives framework and the CPU MIDR detection to
patch "cache clean" into "cache clean and invalidate" instructions if
an affected CPU is detected at
For taking note if at least one CPU in the system needs a bug
workaround or would benefit from a code optimization, we create a new
bitmap to hold (artificial) feature bits.
Since elf_hwcap is part of the userland ABI, we keep it alone and
introduce a new data structure for that (along with some
Not all of the errata we have workarounds for apply necessarily to all

need to patch the kernel.

people to turn off certain bugs if they are not affected. By
This series introduces alternatives runtime patching to arm64.
This allows to patch assembly instruction at runtime to either
fix hardware bugs or optimize for certain hardware features. Look
at patch 5/6 for an example on how to use this.
The code is heavily based on the x86 implementation.

After each CPU has been started, we iterate through a list of
CPU features or bugs to detect CPUs which need (or could benefit
from) kernel code patches.
For each feature/bug there is a function which checks if that
particular CPU is affected. We will later provide some more generic
functions for
With a blatant copy of some x86 bits we introduce the alternative
runtime patching "framework" to arm64.
This is quite basic for now and we only provide the functions we need
at this time.
This is connected to the newly introduced feature bits.

The ARM erratum 832075 applies to certain revisions of Cortex-A57,
one of the workarounds is to change device loads into using
load-aquire semantics.
This is achieved using the alternatives framework.

While working on the cryptd request reordering problem, I noticed
an anomaly where kernel threads are normally allowed to use simd
per may_use_simd, but as soon as you disable softirqs, they suddenly
lose that ability for no good reason.
The problem is that in_interrupt does not distinguish
