brcm2708: update linux 4.4 patches to latest version
As usual these patches were extracted and rebased from the raspberry pi repo:
https://github.com/raspberrypi/linux/tree/rpi-4.4.y
- led1 can't be controlled on rpi-3 for linux 4.4, remove it.
- Fix modules.mk typos.

This patch was developed and discussed on + + https://github.com/raspberrypi/linux/issues/859 + +A precondition to see the crashes is that floating point exception +traps are enabled. In this case, the VFP11 might determine that a FPU +operation needs to trap at a point in time when it is not possible to +signal this to the ARM11 core any more. The VFP11 will then set the +FPEXC.EX bit and store the trapped opcode in FPINST. (In some cases, +a second opcode might have been accepted by the VFP11 before the +exception was detected and could be reported to the ARM11 - in this +case, the VFP11 also sets FPEXC.FP2V and stores the second opcode in +FPINST2.) + +If FPEXC.EX is set, the VFP11 will "bounce" the next FPU opcode issued +by the ARM11 CPU, which will be seen by the ARM11 as an undefined opcode +trap. The VFP support code examines the FPEXC.EX and FPEXC.FP2V bits +to decide what actions to take, i.e., whether to emulate the opcodes +found in FPINST and FPINST2, and whether to retry the bounced instruction. + +If a user space application has left the VFP11 in this "pending trap" +state, the next FPU opcode issued to the VFP11 might actually be the +VSTMIA operation vfp_save_state() uses to store the FPU registers +to memory (in our test cases, when building the signal stack frame). +In this case, the kernel crashes as described above. + +This patch fixes the problem by making sure that vfp_save_state() is +always entered with FPEXC.EX cleared. (The current value of FPEXC has +already been saved, so this does not corrupt the context. Clearing +FPEXC.EX has no effects on FPINST or FPINST2. Also note that many +callers already modify FPEXC by setting FPEXC.EN before invoking +vfp_save_state().) + +This patch also addresses a second problem related to FPEXC.EX: After +returning from signal handling, the kernel reloads the VFP context +from the user mode stack. However, the current code explicitly clears +both FPEXC.EX and FPEXC.FP2V during reload. As VFP11 requires these +bits to be preserved, this patch disables clearing them for VFP +implementations belonging to architecture 1. There should be no +negative side effects: the user can set both bits by executing FPU +opcodes anyway, and while user code may now place arbitrary values +into FPINST and FPINST2 (e.g., non-VFP ARM opcodes) the VFP support +code knows which instructions can be emulated, and rejects other +opcodes with "unhandled bounce" messages, so there should be no +security impact from allowing reloading FPEXC.EX and FPEXC.FP2V. + +Signed-off-by: Christopher Alexander Tobias Schulze <cat.schulze@alice-dsl.net> +--- + arch/arm/vfp/vfpmodule.c | 27 ++++++++++++++++++++------- + 1 file changed, 20 insertions(+), 7 deletions(-) + +diff --git a/arch/arm/vfp/vfpmodule.c b/arch/arm/vfp/vfpmodule.c +index 2a61e4b..7675518 100644 +--- a/arch/arm/vfp/vfpmodule.c ++++ b/arch/arm/vfp/vfpmodule.c +@@ -183,8 +183,11 @@ static int vfp_notifier(struct notifier_block *self, unsigned long cmd, void *v) + * case the thread migrates to a different CPU.
