From 3650b0a304663d98a63c68f9020eb1ded477989e Mon Sep 17 00:00:00 2001 From: Grant Likely Date: Mon, 22 Oct 2007 16:38:32 -0600 Subject: [PATCH] ppc: fix AT_VECTOR_SIZE on arch/ppc Commit 4f9a58d75bfe82ab2b8ba5b8506dfb190a267834 ("increase AT_VECTOR_SIZE to terminate saved_auxv properly") changes the size of AT_VECTOR_SIZE from hard coded '44' to a calculation based on the value of AT_VECTOR_SIZE_ARCH and AT_VECTOR_SIZE_BASE. The change works for arch/powerpc, but it breaks arch/ppc because the needed AT_VECTOR_SIZE_ARCH is not present in include/asm-ppc/system.h and a default value of 0 is used instead. This results in AT_VECTOR_SIZE being too small and it causes a kernel crash on loading init.
