That was the generic header change in the patch. I was commenting about the
ppc64 specific change causing build failures.
Ah, sorry. I wasn't aware that the following is valid C code

Until clang-12, clang would attempt to assemble 32b powerpc assembler in
64b emulation mode when using a 64b target triple with -m32, leading to
errors during the build of the compat VDSO. Simply disable all of
CONFIG_COMPAT; users should upgrade to the latest release of clang for
proper support.

While looking at -Wundef warnings, the #if CONFIG_EEH stood out as a
possible candidate to convert to #ifdef CONFIG_EEH.
It seems that based on Kconfig dependencies it's not possible to build
this file without CONFIG_EEH enabled, but based on upstream discussion,
it's not clear yet that CONFIG_EEH

When CONFIG_NEED_MULTIPLE_NODES=y (CONFIG_NUMA=y),
the pglist_data is allocated by a memblock API and stored in an array
named node_data[].

Relocating kernel at runtime is done very early in the boot process, so
it is not convenient to check for relocations there and react in case a
relocation was not expected.
Powerpc architecture has a script that allows to check at compile time
for such unexpected relocations: extract the common lo
After multiple attempts, this patchset is now based on the fact that the
64b kernel mapping was moved outside the linear mapping.
The first patch allows to build relocatable kernels but is not selected
by default. That patch should ease KASLR implementation a lot.
Relocating kernel at runtime is done very early in the boot process, so
it is not convenient to check for relocations there and react in case a
relocation was not expected.
There exists a script in scripts/ that extracts the relocations from
vmlinux that is then used at postlink to check the reloc
This config allows to compile 64b kernel as PIE and to relocate it at
any virtual address at runtime: this paves the way to KASLR.
Runtime relocation is possible since relocation metadata are embedded into
the kernel.
Note that relocating at runtime introduces an overhead even if the
kernel is loa
