The fault_addr argument to fpu_emulator_cop1Handler(), fpux_emu() and cop1Emulate() has up until now been declared as: void *__user *fault_addr This is essentially a pointer in user memory which points to a pointer to void. This is not the intent for our code, which is actually operating on a pointer to a pointer to void where the pointer to void is pointing at user memory. ie. the pointer is in kernel memory & points to user memory. This mismatch produces a lot of sparse warnings that look like this: arch/mips/math-emu/cp1emu.c:1485:45: warning: incorrect type in assignment (different address spaces) expected void *[noderef] <asn:1><noident> got unsigned int [noderef] [usertype] <asn:1>*[assigned] va Fix these by modifying the declaration of the fault_addr argument to: void __user **fault_addr Signed-off-by: Paul Burton <paul.burton@imgtec.com> Cc: linux-mips@linux-mips.org Cc: trivial@kernel.org Patchwork: https://patchwork.linux-mips.org/patch/17173/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org> |
