Currently in __qdf_nbuf_alloc(), __GFP_KSWAPD_RECLAIM flag is
unset before calling kernel APIs for SKB allocation. Since this
flag is not set, in low memory scenarios, nbuf allocations might
fail resulting in firmware assert.
Re-enable the __GFP_KSWAPD_RECLAIM flag to avoid these failures.
It is safe to re-enable this flag since __qdf_nbuf_alloc() does
not request for order-3 allocations any more.

Currently there is an issue wrt truncation in the __qdf_system_time_after()
& __qdf_system_time_after_eq() QDF APIs where the input system ticks
(jiffies) which are of type unsigned long are getting truncated due to
typecast to long before comparison. Due to this typecasting, there is
likelihood of a wrong comparison resulting in wrong actions being
taken in the caller.
Typecast the result of the comparison instead to fix this problem.

For some target like ROME, CE try to read more data than expected as
prefetch. For example in UDP TX case, when CE read a tx_desc(44 bytes)
located in host memory with SMMU mapped address 0x1025FFD4~0x1025FFFF,
SMMU will detect CE read beyond 0x1025FFFF to access 0x10260000. SMMU
fault will happen if 0x10260000 is not mapped to host memory.
To fix this issue, allocate contiguous dma buffer for all 1056 tx_descs,
which will map to contiguous SMMU address region.

Currently RX nbuf data pointer is reset considering
headroom reserve size of NET_SKB_PAD. So while reattaching
buffer back to H.W always data pointer is reset back to head plus
NET_SKB_PAD offset. But if skb is not allocated with head room
reserve then we should not reset data pointer taking NET_SKB_PAD
as consideration.
Fix this by pushing nbuf data pointer back to the state when
nbuf entered the host.

When CONFIG_QCOM_IOMMU_UTIL is enable in vendor config, we have to
use new set of API's to get iommu domain attributes, and while using
__qdf_iommu_attr_to_os seeing compilation issue as some identifiers
like, QCOM_IOMMU_MAPPING_CONF_S1_BYPASS are not declare.
even when CONFIG_QCOM_IOMMU_UTIL is not enable we have dependency
on qcom-iommu-util.h file as it has some identfiers which are in use,
with or without CONFIG_QOM_IOMMU_UTIL.
Fix is to include the header file qcom-iommu-util.h which contains
the declaration of all the identifiers used in __qdf_iommu_attr_to_os
and this file is included if MSM_PLATFORM or QCA_IPA_LL_TX_FLOW_CONTROL
is defined.

SKBs that are allocated using __netdev_alloc_skb() share a single
page frag cache that is maintained in the network layer and is
common for all network drivers/devices. There is always a chance
where memory can be fragmented when the WLAN driver shares a page
frag cache with other slow network devices. Over the time, lot of
memory would be wasted due to fragmentation eventually resulting
in SKB allocation failures due to OOM.
To circumvent this, define a QDF NBUF allocation API which accepts
custom page frag cache maintained in the driver as an input and
allocates memory for skb->head from the custom page frag cache.
Such an API will be of great help when used for allocating reusable
SKBs in the driver. This also avoids the aforementioned memory
fragmentation issue.
