If the asssocated access point is strong byBBVGACurrent will be adjusted
accordingly.
Users will nolonger see distant access points without taking down interface.
When changing channel reset byBBVGACurrent back to pDevice->abyBBVGA[0] for
max sensitivity.

Move PSTxDesc->m_td1TD1 to inside spin locks.
if m_td1TD1.byTCR has TCR_EDP and TCR_STP are set, the interrupt handler will
try and complete the buffer before it is completed. Usually on the tail
of a burst of tx packets.
This results in a partially completed packet being transmitted or worse
sitll dead lock when skb is freed by the interrupt handler.
Set head_td->m_td1TD1.byTCR to 0 in first lock of vnt_tx_packet to stop
interrupt handler completing the buffer. Move Set TSR1 & ReqCount in
s_cbFillTxBufHead to the second lock.
cbReqCount is carried to the second lock in pTDInfo->dwReqCount without
the padding removed.

When batching up address ranges for TLB invalidation, we check tlb->end
!= 0 to indicate that some pages have actually been unmapped.
As of commit f045bbb9fa1b ("mmu_gather: fix over-eager
tlb_flush_mmu_free() calling"), we use the same check for freeing these
pages in order to avoid a performance regression where we call
free_pages_and_swap_cache even when no pages are actually queued up.
Unfortunately, the range could have been reset (tlb->end = 0) by
tlb_end_vma, which has been shown to cause memory leaks on arm64.
Furthermore, investigation into these leaks revealed that the fullmm
case on task exit no longer invalidates the TLB, by virtue of tlb->end
== 0 (in 3.18, need_flush would have been set).
This patch resolves the problem by reverting commit f045bbb9fa1b, using
instead tlb->local.nr as the predicate for page freeing in
tlb_flush_mmu_free and ensuring that tlb->end is initialised to a
non-zero value in the fullmm case.

Commit e4c7f259c5be ("USB: kaweth.c: use GFP_ATOMIC under spin_lock")
makes sure that kaweth_internal_control_msg() allocates memory with GFP_ATOMIC,
but kaweth_internal_control_msg() also calls usb_start_wait_urb()
that still allocates memory with GFP_NOIO.
The patch fixes usb_start_wait_urb() as well.

In commit 58dc55f25631178ee74cd27185956a8f7dcb3e32 ("tipc: use generic
SKB list APIs to manage link transmission queue") we replace all list
traversal loops with the macros skb_queue_walk() or
skb_queue_walk_safe(). While the previous loops were based on the
assumption that the list was NULL-terminated, the standard macros
stop when the iterator reaches the list head, which is non-NULL.
In the function bclink_retransmit_pkt() this macro replacement has
lead to a bug. When we receive a BCAST STATE_MSG we unconditionally
call the function bclink_retransmit_pkt(), whether there really is
anything to retransmit or not, assuming that the sequence number
comparisons will lead to the correct behavior. However, if the
transmission queue is empty, or if there are no eligible buffers in
the transmission queue, we will by mistake pass the list head pointer
to the function tipc_link_retransmit(). Since the list head is not a
valid sk_buff, this leads to a crash.
In this commit we fix this by only calling tipc_link_retransmit()
if we actually found eligible buffers in the transmission queue.

In C one can either use '\0' or '\x00' (or '\000') to add a NUL byte to

Appearance: On some SAMA5D4EK boards, after power up, the Eth1 doesn't work.
Reason: The PIOE2 pin is connected to the NAND_Tree# of KSZ8081,
But it outputs LOW during the reset period, which cause the NAND_Tree# enabled.
Add phy_fixup() to disable NAND_Tree by overriding the Operation
