GM20B GPCPLL registers are accessed via sys address space with the
exception of the last dvfs2 register that can be accessed only through
bcast address. However, in debugfs loop dvfs2 sys address should be
used as loop terminator; otherwise, loop body is never executed, and
GPCPLL registers debugfs node is broken. Fixed it in this commit.

The gr_gk20a_add_zbc() routine returns a signed error
(errno) status value.
Current callers of this function use a bitwise OR to collect
the returned error status values to generate a single value
to return.
Bitwise OR on signed status values is flagged as a
violation of MISRA Rule 10.1 (not to mention that in this
case it potentially results in a garbage return value).
To eliminate such violations this change modifies the
following routines to fail immediately on the first error
from a call to gr_gk20a_add_zbc():
* gr_gk20a_load_zbc_default_table()
* gr_gv11b_load_stencil_default_tbl()

We want to support 1/8th mode only if both endpoints have enabled
it. To know if each endpt supports 1/8th mode in the core driver,
we added a new field in shared nvlink_link struct.
Initialize this new field to false as dGPU nvlink does not currently
support 1/8th mode.

MISRA rule 10.3 prohibits implicit assigning of u64 to u32. The nvgpu was
assigning the value returned by ARRAY_SIZE which is a u64 to a u32. This
value was then returned in a function defined by gpu_ops.
This patch changes the return type for these gpu_ops to u64 and updates
the functions that implement the functions and lastly the saved value. This
removes the violation in this instance.

In nvgpu repository, we have multiple accesses to methods in
pmu_gk20a.h which have register accesses. Instead of directly invoking
these methods, these are now called via HALs. Some common methods such
as pmu_wait_message_cond which donot have any register accesses
are moved to pmu_ipc.c and the method declarations are moved
to pmu.h. Also, changed gm20b_pmu_dbg to
nvgpu_dbg_pmu all across the code base. This would remove all
indirect dependencies via gk20a.h into pmu_gk20a.h. As a result
pmu_gk20a.h is now removed from gk20a.h

MISRA Rule 10.4 only allows the usage of arithmetic operations on
operands of the same essential type category.
Adding "U" at the end of the integer literals to have same type of
operands when an arithmetic operation is performed.
This fix violations where an arithmetic operation is performed on
signed and unsigned int types.
In balloc_get_order_list() the argument "int order" has been changed to
a u64 because all callers of this function pass a u64 argument.

The comptag allocates memory based on the available total RAM, which
theoretically should be the MAX physical RAM size however practically
should deduct the part being taken by the running system. Otherwise,
the taken memory part will never get used and wasted.
This change adds a comptag_mem_deduct to each platform and to allow
them to assign the deductible value based on their own use cases so
as to save memory.

Add READ_SM_ERROR IOCTL support to TSG level.
Moved the struct to save the sm_error details
from gr to tsg as the sm_error support is context
based, not global.
Also corrected MISRA 21.1 error in header file.
nvgpu_dbg_gpu_ioctl_write_single_sm_error_state and
nvgpu_dbg_gpu_ioctl_read_single_sm_error_state
functions are modified to use the tsg struct
nvgpu_tsg_sm_error_state.

602112 __nvgpu_vzalloc+0x28/0x78 [nvgpu] pages=146 vmalloc
This change just simply reorgnizes the member defines in those two
structures to reduce padding waste. After this change:

733184 __nvgpu_vzalloc+0x28/0x78 [nvgpu] pages=178 vmalloc
585728 __nvgpu_vzalloc+0x28/0x78 [nvgpu] pages=142 vmalloc
In summary, it saves 8 pages in 32KB memory.

Fix MISRA rule 10.1 violations involving gk20a_nonstall_ops
enums by replacing them with with corresponding #defines.
Because these values can be used in expressions that require
unsigned values (e.g. bitwise OR) we cannot use enums.
The g->ce2.isr_nonstall() function was previously returning an
int that was a combination of gk20a_nonstall_ops enum bits which
led to the violations.

The enum gmmu_pgsz_gk20a was being used in for loops, where it was
compared with an integer. This violates MISRA rule 10.4, which only
allows arithmetic operations on operands of the same essential type
category. Changing this enum into macro will fix this violation.
