commit: c0e01d5d8f15c085236df184e5bc3d79a8b700cd From: Will Deacon <[email protected]> Date: Wed, 6 Feb 2013 11:42:23 +0000 Subject: arm64: compat: use compat_uptr_t type for compat_ucontext.uc_link
struct compat_ucontext * is a 64-bit pointer, so we need to use a compat_uptr_t instead to avoid declaring a structure incompatible with what AArch32 userspace expects.
