Subject: parisc: support R_PARISC_SECREL32 relocation in modules
From: Mikulas Patocka <mpatocka@xxxxxxxxxx>
commit 5f655322b1ba4bd46e26e307d04098f9c84df764 upstream.
The parisc kernel doesn't work with CONFIG_MODVERSIONS since the commit
71810db27c1c853b335675bee335d893bc3d324b. It can't load modules with the
error: "module unix: Unknown relocation: 41".
The commit changes __kcrctab from 64-bit valus to 32-bit values. The
assembler generates R_PARISC_SECREL32 secrel relocation for them and the
module loader doesn't support this relocation.
This patch adds the R_PARISC_SECREL32 relocation to the module loader.
