Date: Tue, 26 Feb 2013 15:56:04 -0800 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, stable@...r.kernel.org, Edmund Grimley-Evans <Edmund.Grimley-Evans@....com>, Will Deacon <will.deacon@....com>, Catalin Marinas <catalin.marinas@....com> Subject: [ 107/150] arm64: compat: use compat_uptr_t type for compat_ucontext.uc_link 3.8-stable review patch. If anyone has any objections, please let me know. ------------------ From: Will Deacon <will.deacon@....com> commit c0e01d5d8f15c085236df184e5bc3d79a8b700cd upstream. 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.
