The current regular expression for strip attributes of structs (and
for nested ones as well) also removes all whitespaces that may
surround the attribute. After that, the code will split structs and
iterate for each symbol separated by comma at the end of struct
definition (e.g. "} alias1, alias2;"
Subroutine dump_struct uses type attributes to check if the struct
syntax is valid. Then, it removes all attributes before using it for
output. `cacheline_aligned_in_smp` is an attribute that is
not included in both steps. Add it, since it is used by kernel structs.

Hello,
This patch series improves kernel-doc script at dump_struct()
subroutine by solving a bug and by making the parser more complete.
The current way that scripts/kernel-doc dump structs do not work for
nested structs with attributes (e.g. __packed) and without type alias
(e.g } alias1;). This

The activity monitors extension is an optional extension introduced

Add initial documentation for the AMUv1 extension:
- arm64/amu.txt: AMUv1 documentation
- arm64/booting.txt: system registers initialisation
- arm64/cpu-feature-registers.txt: visibility to user
The activity monitors extension is an optional extension introduced
by the ARMv8.4 CPU architecture. This implements basic support for
version 1 of the activity monitors architecture, AMUv1.
This support includes:
- Extension detection on each CPU (boot, secondary, hotplugged)
- Register interface
The activity monitors extension is an optional extension introduced
by the ARMv8.4 CPU architecture. In order to access the activity
monitors counters safely, if desired, the kernel should detect the
presence of the extension through the feature register, and mediate
the access.
Therefore, disable
Access to the AMU counters should be disabled by default in kvm guests,
as information from the counters might reveal activity in other guests
or activity on the host.
Therefore, disable access to AMU registers from EL0 and EL1 in kvm
guests by:
- Hiding the presence of the extension in the featu
These patches introduce support for the Activity Monitors Unit (AMU)
CPU extension, an optional extension in ARMv8.4 CPUs. This provides
performance counters intended for system management use.
With the CONFIG_ARM64_AMU_EXTN enabled the kernel is able to safely
run a mix of CPUs with and without s

A number of issues are fixed relating to sysfs input validation:-
1) bb_ctrl_store() - incorrect compare of bit select field to absolute

TRCACATRn registers have match bits for secure and non-secure exception

This adds a new sysfs parameter to enable this - addr_exlevel_s_ns.
Looks good to me. Some minor nits below.

It has been suggested several times to extend vsnprintf() to be able
to convert the numeric value of ENOSPC to print "ENOSPC". This is yet
another attempt. Rather than adding another %p extension, simply teach
plain %p to convert ERR_PTRs. While the primary use case is
