riscv: s64ilp32: Temporary workaround solution to gcc problem
There is an existing problem in 64ilp32 gcc that combines two pointers in one register. Liao is solving that problem. Before he finishes the job, we could prevent it with a simple noinline attribute, fortunately. struct path { struct vfsmount *mnt; struct dentry *dentry; } __randomize_layout; struct nameidata { struct path path; struct qstr last; struct path root; ... } __randomize_layout; struct nameidata *nd ... nd->path = nd->root; 6c88 ld a0,24(s1) ^^ // Wrong arg of mntget e088 sd a0,0(s1) // Need inserting "lw a0,0(s1)" here mntget(path->mnt); 2a6150ef jal c01ce946 <mntget> Any gcc helps are welcome :) Signed-off-by: Guo Ren <guoren@linux.alibaba.com> Signed-off-by: Guo Ren <guoren@kernel.org> Cc: LiaoShihua <shihua@iscas.ac.cn>
