The ctxsw ucode saves all the ctxsw'ed TPC priv registers in the TPC
priv segment of the ctxsw image. In ga10b, these registers can be stored
in either of the two arrangements:
- INTERLEAVED: means the format is sorted by address first, then by TPC number
- MIGRATION: exact opposite of interleaved.
Update HAL functions gr_ga10b_process_context_buffer_priv_segment,
gr_ga10b_find_priv_offset_in_buffer to detect the register layout and
calculate the register offset accordingly.

Most of the Orin chip specific code is compiled out of safety build
with CONFIG_NVGPU_NON_FUSA and CONFIG_NVGPU_HAL_NON_FUSA. Remove the
config protection from Orin/GA10B specific code. Currently all code
is enabled. Code not required in safety will be compiled out later
in separate activity.
Other noteworthy changes in this patch related to safety build:
- In ga10b_ce_request_idle(), add a log print to dump num_pce so that
compiler does not complain about unused variable num_pce.
- In ga10b_fifo_ctxsw_timeout_isr(), protect variables active_eng_id and
recover under CONFIG_NVGPU_KERNEL_MODE_SUBMIT to fix compilation
errors of unused variables.
- Compile out HAL gops.pbdma.force_ce_split() from safety since this HAL
is GA100 specific and not required for GA10B.
- Compile out gr_ga100_process_context_buffer_priv_segment() with
CONFIG_NVGPU_DEBUGGER.
- Compile out VAB support with CONFIG_NVGPU_HAL_NON_FUSA.
- In ga10b_gr_intr_handle_sw_method(), protect left_shift_by_2 variable
with appropriate configs to fix unused variable compilation error.
- In ga10b_intr_isr_stall_host2soc_3(), compile ELPG function calls
with CONFIG_NVGPU_POWER_PG.
- In ga10b_pmu_handle_swgen1_irq(), move whole function body under
CONFIG_NVGPU_FALCON_DEBUG to fix unused variable compilation errors.
- Add below TU104 specific files in safety build since some of the code
in those files is required for GA10B. Unnecessary code will be
compiled out later on.
hal/gr/init/gr_init_tu104.c
hal/class/class_tu104.c
hal/mc/mc_tu104.c
hal/fifo/usermode_tu104.c
hal/gr/falcon/gr_falcon_tu104.c
- Compile out GA10B specific debugger/profiler related files from
safety build.
- Disable CONFIG_NVGPU_FALCON_DEBUG from safety debug build temporarily
to work around compilation errors seen with keeping this config
enabled. Config will be re-enabled in safety debug build later.

GFxP preemption for graphics contexts is not supported in safety.
But the support was enabled along with CONFIG_NVGPU_GRAPHICS since GFxP
preemption was protected under same config.
Add a separate config CONFIG_NVGPU_GFXP to protect all GFxP specific
code, enum values, and HALs.
Disable the config in safety profile.

All graphics code is under CONFIG_NVGPU_GRAPHICS and all the HALs are
in non-fusa files. In order to support graphics in safety,
CONFIG_NVGPU_GRAPHICS needs to be enabled. But since most of the HALs
are in non-fusa files, this causes huge compilation problem.
Fix this by moving all graphics specific HALs used on gv11b to fusa
files. Graphics specific HALs not used on gv11b remain in non-fusa files
and need not be protected with GRAPHICS config.
Protect call to nvgpu_pmu_save_zbc() also with config
CONFIG_NVGPU_POWER_PG, since it is implemented under that config.
Delete hal/ltc/ltc_gv11b.c since sole function in this file is moved to
fusa file.
Enable nvgpu_writel_loop() in safety build since it is needed for now.
This will be revisited later once requirements are clearer.
Move below CTXSW methods under CONFIG_NVGPU_NON_FUSA for now. Safety
CTXSW ucode does not support these methods. These too will be revisited
later once requirements are clearer.

Multiple non-safe functions under NVGPU_DEBUGGER, NVGPU_CILP and other

the C flags, it makes sense to keep those functions in non-fusa

The whitelisting macros have been added to a new header called

been moved into static_analysis.h because this will be the new header

MISRA rule 11.3 states that a cast shall not be performed between
a pointer to object type and a pointer to a different object type.
The following gr context routines convert a gr context buffer pointer
in the form of a u8 * to a u32 * before referencing the context buffer's
contents:
* gm20b_ctxsw_prog_check_main_image_header_magic
* gm20b_ctxsw_prog_check_local_header_magic
* gm20b_ctxsw_prog_get_num_gpcs
* gm20b_ctxsw_prog_get_num_tpcs
* gm20b_ctxsw_prog_get_extended_buffer_size_offset
* gm20b_ctxsw_prog_get_ppc_info
* gm20b_ctxsw_prog_get_local_priv_register_ctl_offset
Because the gr context buffer pointer starts out as a u32 * the
conversion to a u8 * isn't strictly necessary.
So this patch eliminates the conversion and the 11.3 rule violations
accordingly.
