Subject: update x86_64-vdso-install-unstripped-copies-on-disk
From: Roland McGrath <roland@xxxxxxxxxx>
While integrating these with the Fedora kernel build, I worked out a few kinks.
This patch replaces x86_64-vdso-install-unstripped-copies-on-disk.patch
and expects x86_64-ia32-vdso-install-unstripped-copies-on-disk.patch
was applied first.
This keeps an unstripped copy of the vDSO images built before they are
stripped and embedded in the kernel. The unstripped copies get installed
in $(MODLIB)/vdso/ by "make install" (or you can explicitly use the
subtarget "make vdso_install"). These files can be useful when they
contain source-level debugging information.
