x86/fpu/xsave: Keep __user annotation in casts Don't remove the __user annotation of the fpstate pointer, but drop the superfluous void * cast instead. This fixes the following sparse warnings: xsave.c:135:15: warning: cast removes address space of expression xsave.c:135:15: warning: incorrect type in argument 1 (different address spaces) xsave.c:135:15: expected void const volatile [noderef] <asn:1>*<noident> [...] Signed-off-by: Mathias Krause <mini...@googlemail.com> Cc: Suresh Siddha <suresh.b.sid...@intel.com> Link: http://lkml.kernel.org/r/1346621506-30857-6-git-send-email-mini...@googlemail.com Signed-off-by: Ingo Molnar <mi...@kernel.org> --- arch/x86/kernel/xsave.c | 6 +++--- 1 files changed, 3 insertions(+), 3 deletions(-) diff --git a/arch/x86/kernel/xsave.c b/arch/x86/kernel/xsave.c index 3d3e207..9e1a8a7 100644 --- a/arch/x86/kernel/xsave.c +++ b/arch/x86/kernel/xsave.c @@ -132,9 +132,9 @@ int check_for_xstate(struct i387_fxsave_struct __user *buf, fx_sw_user->xstate_size > fx_sw_user->extended_size) return -EINVAL; - err = __get_user(magic2, (__u32 *) (((void *)fpstate) + - fx_sw_user->extended_size - - FP_XSTATE_MAGIC2_SIZE)); + err = __get_user(magic2, (__u32 __user *) (fpstate + + fx_sw_user->extended_size - + FP_XSTATE_MAGIC2_SIZE)); if (err) return err; /* -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
