fc35bcd19b gpu: nvgpu: remove sysfs from safety build
- The only sysfs node supported on safety build
was "/dev/gpu_powered_on".
- In QNX, GPU is always powered on. So, this sysfs node doesn't
convey any extra info. Hence, this patch removes sysfs from safety
build.

76c1a704bd gpu: nvgpu: compile out unused code with safety build for gr.falcon
Compile out unused code in gr.falcon for safety build.
By default NVGPU_SEC_SECUREGPCCS is enabled in Safety build. Add
CONFIG_NVGU_GR_FALCON_NON_SECURE_BOOT checking with non secure code.

In gm20b_gr_falcon_wait_ctxsw_ready function watchdog timer value is
calculated based on clock rate, not needed for safety code.
Add CONFIG_NVGPU_HAL_NON_FUSE checking for unused code in that function.

gm20b_gr_falcon_gr_code_less_equal is the last op status we check.
SKIP or any other status following this will be failed in checking
for valid op status. So code reaching this function mean it is for
only for GR_IS_UCODE_OP_LESSER_EQUAL. So removing the checking for 
opc_status != GR_IS_UCODE_OP_LESSER_EQUAL in this function

a560a378a1 gpu: nvgpu: ce: fifo: fix CE interrupt mask
Fix bug where the CE mask includes other engine types besides just CEs
in nvgpu_ce_engine_interrupt_mask().

The intent of this API is to return mask of CE interrupts. However, the
if clause in the for loop is only excluding engine interrupts if the CE
stall or non-stall ISR is NULL. So, it does not distinquish between CE
or GR engine interrupts if the CE ISR is non-null.

Since the expectation is to not return CE interrupts if the ISRs are
NULL, just return a 0 mask if either ISR is NULL without having to
bother with the loop.

If the ISRs are set in the CE HAL, within the loop, only add interrupts
to the mask returned if the engine type is actually a CE engine (i.e. do
not include GR engine interrupts).

a52ee77837 gpu: nvgpu: Add SM diversity gpu characteristic flag
To achieve permanent fault coverage, the CTAs launched by
each kernel in the mission and redundant contexts must execute
on different hardware resources.
This feature requires a change in software to make it possible
to modify the virtual SM id to TPC mapping across mission and
redundant contexts.

This CL adds only SM diversity flags which are exposed to
its clients through ioctl/devctl interfaces.
Actual virtual SM id to TPC mapping implementation
will be part of upcoming patch sets.

Added NvGpu CFLAGS to identify the safety build
"CONFIG_NVGPU_BUILD_CONFIGURATION_IS_SAFETY"
