The upstream binutils commit below reduced the section alignment of
|
|
armhf executables (including shared libraries) from 64k to 4k, on the
|
|
basis that the additional bloat is not justified, given that arm64 hosts
|
|
running 64k pagesize kernels with armhf user space are not used in
|
|
practice.
|
|
|
|
However, the situation is slightly different today on Debian, where a
|
|
16k pagesize kernel is provided that enables compat support, and is
|
|
therefore able to execute armhf user space. The only impediment is the
|
|
fact that armhf binaries are no longer compatible with this, due to the
|
|
change below.
|
|
|
|
To accommodate this use case, revert the patch. This makes the generated
|
|
executables compatible with compat mode on arm64 systems running 16k
|
|
kernels.
