#     
#     Pull MIPS fixes from Paul Burton:
#      "A collection of MIPS fixes:
#     
#        - Fill the struct cacheinfo shared_cpu_map field with sensible
#          values, notably avoiding issues with perf which was unhappy in the
#          absence of these values.
#     
#        - A boot fix for Loongson 2E & 2F machines which was fallout from
#          some refactoring performed this cycle.
#     
#        - A Kconfig dependency fix for the Loongson CPU HWMon driver.
#     
#        - A couple of VDSO fixes, ensuring gettimeofday() behaves
#          appropriately for kernel configurations that don't include support
#          for a clocksource the VDSO can use & fixing the calling convention
#          for the n32 & n64 VDSOs which would previously clobber the $gp/$28
#          register.
#     
#        - A build fix for vmlinuz compressed images which were
#          inappropriately building with -fsanitize-coverage despite not being
#          part of the kernel proper, then failing to link due to the missing
#          __sanitizer_cov_trace_pc() function.
#     
#        - A couple of eBPF JIT fixes, including disabling it for MIPS32 due
#          to a large number of issues with the code generated there &
#          reflecting ISA dependencies in Kconfig to enforce that systems
#          which don't support the JIT must include the interpreter"
#

WARNING: vmlinux.o(.text+0x31e4): Section mismatch in reference from the variable __boot_from_prom to the function .init.text:prom_init()
The function __boot_from_prom() references
the function __init prom_init().
This is often because __boot_from_prom lacks a __init 
annotation or the annotation of prom_init is wrong.

The function start_here_common() references
the function __init start_kernel().
This is often because start_here_common lacks a __init 
annotation or the annotation of start_kernel is wrong.
