[ Upstream commit bc8a2d9bcb ]
The Stratix10 platform has an additional reset line, OCP(Open Core Protocol),
that also needs to get deasserted for the stmmac ethernet controller to work.
Thus we need to update the Kconfig to include ARCH_STRATIX10 in order to build
dwmac-socfpga.
Also, remove the redundant check for the reset controller pointer. The
reset driver already checks for the pointer and returns 0 if the pointer
is NULL.

The array bpq_eth_addr is only used to get the size of an
address, whereas the bcast_addr is used to set the broadcast
address. This leads to a warning when using clang:

[ Upstream commit 70c3c8cb83 ]
If isoc split in transfer with no data (the length of DATA0
packet is zero), we can't simply return immediately. Because
the DATA0 can be the first transaction or the second transaction
for the isoc split in transaction. If the DATA0 packet with no
data is in the first transaction, we can return immediately.
But if the DATA0 packet with no data is in the second transaction
of isoc split in transaction sequence, we need to increase the
qtd->isoc_frame_index and giveback urb to device driver if needed,
otherwise, the MDATA packet will be lost.
A typical test case is that connect the dwc2 controller with an
usb hs Hub (GL852G-12), and plug an usb fs audio device (Plantronics
headset) into the downstream port of Hub. Then use the usb mic
to record, we can find noise when playback.
In the case, the isoc split in transaction sequence like this:
- SSPLIT IN transaction
- CSPLIT IN transaction
- MDATA packet (176 bytes)
- CSPLIT IN transaction
- DATA0 packet (0 byte)
This patch use both the length of DATA0 and qtd->isoc_split_offset
to check if the DATA0 is in the second transaction.

arc-elf32-ld: final link failed: Symbol needs debug section which does not exist

commit b3681dd548 upstream.
error_entry and error_exit communicate the user vs. kernel status of
the frame using %ebx. This is unnecessary -- the information is in
regs->cs. Just use regs->cs.
This makes error_entry simpler and makes error_exit more robust.
It also fixes a nasty bug. Before all the Spectre nonsense, the
xen_failsafe_callback entry point returned like this:
ALLOC_PT_GPREGS_ON_STACK
SAVE_C_REGS
SAVE_EXTRA_REGS
ENCODE_FRAME_POINTER
jmp error_exit
And it did not go through error_entry. This was bogus: RBX
contained garbage, and error_exit expected a flag in RBX.
Fortunately, it generally contained *nonzero* garbage, so the
correct code path was used. As part of the Spectre fixes, code was
added to clear RBX to mitigate certain speculation attacks. Now,
depending on kernel configuration, RBX got zeroed and, when running
some Wine workloads, the kernel crashes. This was introduced by:
commit 3ac6d8c787 ("x86/entry/64: Clear registers for exceptions/interrupts, to reduce speculation attack surface")
With this patch applied, RBX is no longer needed as a flag, and the
problem goes away.
I suspect that malicious userspace could use this bug to crash the
kernel even without the offending patch applied, though.
[ Historical note: I wrote this patch as a cleanup before I was aware
of the bug it fixed. ]
[ Note to stable maintainers: this should probably get applied to all
kernels. If you're nervous about that, a more conservative fix to
add xorl %ebx,%ebx; incl %ebx before the jump to error_exit should
also fix the problem. ]

dw8250_set_termios() doesn't set baud rate if the arg "old ktermios" is
NULL. This happens during resume.
Call Trace:
...
[ 54.928108] dw8250_set_termios+0x162/0x170

[ 54.928117] uart_change_speed+0x64/0x160
[ 54.928119] uart_resume_port
...
So the baud rate is not restored after S3 and breaks the apps who use
UART, for example, console and bluetooth etc.
We address this issue by setting the baud rate irrespective of arg
"old", just like the drivers for other 8250 IPs. This is tested with

commit 231f941500 upstream.
Every time I tried to upgrade my laptop from 3.10.x to 4.x I faced an
issue by which the fan would run at full speed upon resume. Bisecting
it showed me the issue was introduced in 3.17 by commit 821d6f0359
(ACPI / sleep: Do not save NVS for new machines to accelerate S3). This
code only affects machines built starting as of 2012, but this Asus
1025C laptop was made in 2012 and apparently needs the NVS data to be
saved, otherwise the CPU's thermal state is not properly reported on
resume and the fan runs at full speed upon resume.
Here's a very simple way to check if such a machine is affected :
# cat /sys/class/thermal/thermal_zone0/temp
55000
( now suspend, wait one second and resume )
# cat /sys/class/thermal/thermal_zone0/temp
0
(and after ~15 seconds the fan starts to spin)
Let's apply the same quirk as commit cbc00c13 (ACPI: save NVS memory
for Lenovo G50-45) and reuse the function it provides. Note that this
commit was already backported to 4.9.x but not 4.4.x.

commit dfef01e150 upstream.
snd_dma_alloc_pages_fallback() tries to allocate pages again when the
allocation fails with reduced size. But the first try actually
*increases* the size to power-of-two, which may give back a larger
chunk than the requested size. This confuses the callers, e.g. sgbuf
assumes that the size is equal or less, and it may result in a bad
loop due to the underflow and eventually lead to Oops.
The code of this function seems incorrectly assuming the usage of
get_order(). We need to decrease at first, then align to
power-of-two.

commit d77a4b4a5b upstream.
As an equivalent codec with CX20724,
CX8200 is also subject to the reboot bug.
Late 2017 and 2018 LG Gram and some HP Spectre laptops are known victims
to this issue, causing extremely loud noises upon reboot.
Now that we know that this bug is subject to multiple codecs,
fix the comment as well.

commit f59cf9a055 upstream.
On rare occasions, we are still noticing that the internal speaker
spitting out spurious noises even after adding the problematic codec
to the list.
Adding a 10ms artificial delay before rebooting fixes the issue entirely.
Patch for Realtek codecs also adds the same amount of delay after
entering D3.
