substantial progress, I will report it here.

There is a new ASRC included in i.MX serial platform, there
are some common definition can be shared with each other.
So move the common definition to a separate header file.

EASRC (Enhanced Asynchronous Sample Rate Converter) is a new IP module
found on i.MX815. It is different with old ASRC module.
The primary features for the EASRC are as follows:
- 4 Contexts - groups of channels with an independent time base
- Fully independent and concurrent context control
- Sim
kcov instrumentation is collected the __sanitizer_cov_trace_pc hook in
kernel/kcov.c. The compiler inserts these hooks into every basic block
unless kcov is disabled for that file.
We then have a deep call-chain:
- __sanitizer_cov_trace_pc calls to check_kcov_mode()
- check_kcov_mode() (kernel/k

Building on the work of Christophe, Aneesh and Balbir, I've ported
KASAN to 64-bit Book3S kernels running on the Radix MMU.
This provides full inline instrumentation on radix, but does require
that you be able to specify the amount of physically contiguous memory
on the system at compile time. Mor
powerpc has a variable number of PTRS_PER_*, set at runtime based
on the MMU that the kernel is booted under.
This means the PTRS_PER_* are no longer constants, and therefore
breaks the build.
Define default MAX_PTRS_PER_*s in the same style as MAX_PTRS_PER_P4D.
As KASAN is the only user at the m
KASAN is supported on 32-bit powerpc and the docs should reflect this.

KASAN support on Book3S is a bit tricky to get right:
- It would be good to support inline instrumentation so as to be able to
catch stack issues that cannot be caught with outline mode.
- Inline instrumentation requires a fixed offset.
- Book3S runs code in real mode after booting. Most n
