Remove check added in previous patch to disallow size zero to be
passed from user space in dma_mem_create(). Size zero is deemed valid
if the memory region is already created and a second user wishes to
get a mapping to the existent memory.
Corrected values copied back to the user to include the length of the
memory and the flags. This is important to reflect a memory size
correction when the user passes size zero. The user can check the new
size using dma_mem_params()
Added a warning message if the user attempts to map to an existing
area in memory, but specifies a non-zero size that does not match the
original memory mapping. In the future this case will trigger an
error and the mapping will fail. Currently the behavior is to print a
warning message and the kernel passes back to user space the
corrected size.

is_power_of_2 is a Linux function that takes unsigned long. it was
used by our new function is_power_of_4 which takes u64. Trucation
is possible because unsigned long is 32 bits wide in 32 bit
applications. This patch removes the dependancy on is_power_of_2 to
solve this issue

ioctl_dma_map. String length check
Added check to ensure the string copied from user space is within
the length allowed for by the buffer and is null terminated.
qm_shutdown_fq. Remove deadcode
Removed the case statement label for QM_MCR_NP_STATE_OOS since
that condition is checked for earlier in the code and in that
case the function exits immediately.
ioctl_dma_lock. Remove NULL dereference
A pointer is made null and then there is an attempt to dereference one
of the members of the struct that it points to. This condition is never
reached normally, but in error conditions this path of execution may be
possible.
Added return -EFAULT to exit function safely and unlocked locked resources
usdpaa_get_unmapped_area. Arithmetic overflow protection
Added a check to ensure that memory length passed in does not result in
an invalid size to be passed because of a possible arithmetic overflow
that can occur in the subtraction in the macro USDPAA_MEM_ROUNDUP.
qman_ceetm_ccg_claim. If condition fix
Removed a check against an unsigned int value that checks if it is
below zero (negative). The unsigned value cannot be negative and the
compare will always fail in reality.
qman_create_portal. Add comment to clarify flow
Clarified why no check is made to ensure that qm_mr_current()
returned successfully. The addition of a redundant check was rejected
because it impairs the reader's understanding of the flow
by implying the possibility of a physically impossible path.
dpa_alloc_new. Fix memory leak in error conditions
Previously allocated memory which is passed by reference in
success (list_add_tail) is not freed in error conditions
that occur in other parts of the function. Added code to free
allocated memory in error cases.
qman_create_portal. Fix memory leak in error path
Added cleanup code that deletes malloced memory in case
of function failure after memory is allocated.
ioctl_dma_map. Input bound checks on values from USDPAA
Check the struct usdpaa_ioctl_dma_map, input, to ensure that values
copied from user space are valid input.
qman_init. Check init_pcfg return
Previously unused assignment is now being used. The return of
init_pcfg() was not checked for success. Now we check for success
and print an error message in case of failure.
There is a similar issue in bman_driver.

To acknowledge a DQRR entry, the portal should be preserved in same mode
as it was when the DQRR entry was created. Function qm_dqrr_init() is
invoked when a raw portal is released back. The raw portal could be
either in one of cci or cci or cdc modes. So while cleaning up a portal
using qm_dqrr_init(), the dqrr consumption mode should be read and
accordingly approriate DQRR consumption routine should be invoked.

This patch modifies the USDPAA code to allow non power of 4 DMA

In some situations frame queues may still be on a work queue when
a retirement command is sent during cleanup. In order to reach the
retired state these frame queues must be scheduled. This patch sets
an appropriate SDQCR value to ensure that the Frame Queue is scheduled.
Since Frame Queues could be 'locked' to a particular portal if the
Hold Active feature is enabled the shutrown routine must service
all portals to ensure that the FQ reaches a retired state

The fsl_usdpaa.c code to find the portal that corresponds to a given
mapped region already has to differentiate between qman and bman, so
localise it there under a single function, rather than having
fsl_usdpaa_irq.c distinguish as well and call qman and bman specific
functions.
