Gently ping, any comments or suggestions?
Thanks

Replace the conditional compilation using "#ifdef CONFIG_KEXEC_CORE"
by a check for "IS_ENABLED(CONFIG_KEXEC_CORE)", to simplify the code

Move the definition and declaration of global variable crashk[_low]_res
from kexec module to crash_core module, in preparation of adding generic
reserve_crashkernel_mem[_low]() to crash_core.c, the latter refers to
variable crashk[_low]_res.

Use parse_crashkernel_high_low() to bring the parsing of

are strongly dependent, make code logic clear and more readable.

The bootup command line option crashkernel=Y,low is valid only when

Module verification already implements appeded signature check.
Reuse it for kexec_file.
The kexec_file implementation uses EKEYREJECTED error in some cases when
there is no key and the common implementation uses ENOPKG or EBADMSG
instead.

Multiple users of mod_check_sig check for the marker, then call
mod_check_sig, extract signature length, and remove the signature.
Put this code in one place together with mod_check_sig.
This changes the error from ENOENT to ENODATA for ima_read_modsig in the
case the signature marker is
It is stripped by each caller separately.
Note: this changes the error for kexec_file from EKEYREJECTED to ENODATA
when the signature marker is missing.

Hello,
This is a refresh of the KEXEC_SIG series.
This adds KEXEC_SIG support on powerpc and deduplicates the code dealing
with appended signatures in the kernel.
powerpc supports IMA_KEXEC but that's an exception rather than the norm.
On the other hand, KEXEC_SIG is portable across platforms.
Add value for kexec appended signature and pass in key_being_used_for
enum rather than a string to verify_appended_signature to produce log
messages about the signature.
