Subject: [GIT PULL] x86/kdump for v6.0

Hi Linus,

please pull two x86/kdump updates for 6.0.

That branch will conflict a bit with the previous x86/build pull, the
resolution is simple though (courtesy of mingo):

Merge: 68b8e9713c8e 2d17bd24b016
Author: Ingo Molnar <mingo@...nel.org>
Date:   Tue Jul 26 09:06:10 2022 +0200

    Merge branch 'x86/build' into x86/kdump, to resolve conflict
    
    The following commit in x86/build made the use of BUILD_BIN2C unnecessary:
    
      2d17bd24b016 ("x86/purgatory: Omit use of bin2c")
    
    Propagate this to x86/kdump as well, where the following commit
    modified the same "config KEXEC_FILE" block:
    
      b69a2afd5afc ("x86/kexec: Carry forward IMA measurement log on kexec")
    
     Conflicts:
            arch/x86/Kconfig
