Increase max i2c bus frequency beyond the default for faster
data transfers. According to the manual, these faster speeds are
only available when the board is wired up the right way. In this case,
the vendor kernel has run at this speed for a long time.
sda-delay is needed for talking to RTC on PMIC, otherwise the i2c
controller never sees an ACK. Strangely the other PMIC i2c slave (the
main one) works fine even without this delay. I Chose value 100 to
match the vendor kernel.

The ODROID kernel shows that the PMIC interrupt line is hooked up
to pin GPX3-2.
This is needed for the max77686-irq driver to create the PMIC IRQ

Currently when run on an APM platform the ARMv8 defconfig has no viable
options for rootfs other than ramdisk which is rather limiting. Since
we already have both SATA and the bits needed for NFS root enabled we just
need to enable the relevant drivers so do that, helping enable direct
testing of upstream.
If the configuration ends up becoming too big we can consider modularising
some of the drivers and asking people to use an initramfs but for now this
is not an issue.

When booting via UEFI, the kernel Image is loaded at a 4 kB boundary and
the embedded EFI stub is executed in place. The EFI stub relocates the
Image to reside TEXT_OFFSET bytes above a 2 MB boundary, and jumps into
the kernel proper.
In AArch64, PC relative symbol references are emitted using adrp/add or
adrp/ldr pairs, where the offset into a 4 kB page is resolved using a
separate :lo12: relocation. This implicitly assumes that the code will
always be executed at the same relative offset with respect to a 4 kB
boundary, or the references will point to the wrong address.
This means we should link the kernel at a 4 kB aligned base address in
order to remain compatible with the base address the UEFI loader uses
when doing the initial load of Image. So update the code that generates
TEXT_OFFSET to choose a multiple of 4 kB.
At the same time, update the code so it chooses from the interval [0..2MB)
as the author originally intended.

cbq: incorrectly low bandwidth blocks limited traffic

Mainstream commit f0f6ee1f70c4 ("cbq: incorrect processing of high limits")

throughput non-limited traffic can delay limited traffic for a very long time.
This happen because of q->now changes incorrectly in cbq_dequeue():

and q->now gets an extra boost for each transmitted packet.
Accumulated boost prevents update q->now, and blocked class can wait

The latest kernel fails to boot qemu arm images when using scsi
for disk access. Boot gets stuck after the following messages.
brd: module loaded

sym0: No NVRAM, ID 7, Fast-40, LVD, parity checking
sym0: SCSI BUS has been reset.
scsi host0: sym-2.2.3
Bisect points to commit 71e75c97f97a ("scsi: convert device_busy to
atomic_t"). Code inspection shows the following suspicious change
in scsi_request_fn.
out_delay:
- if (sdev->device_busy == 0 && !scsi_device_blocked(sdev))
+ if (atomic_read(&sdev->device_busy) && !scsi_device_blocked(sdev))
blk_delay_queue(q, SCSI_QUEUE_DELAY);
}
'sdev->device_busy == 0' was replaced with 'atomic_read(&sdev->device_busy)',
meaning the logic was reversed. Changing this expression to
'!atomic_read(&sdev->device_busy)' fixes the problem.

We did not check relocated directory in any way when processing Rock
Ridge 'CL' tag. Thus a corrupted isofs image can possibly have a CL
entry pointing to another CL entry leading to possibly unbounded
recursion in kernel code and thus stack overflow or deadlocks (if there
is a loop created from CL entries).
Fix the problem by not allowing CL entry to point to a directory entry
with CL entry (such use makes no good sense anyway) and by checking
whether CL entry doesn't point to itself.

When we manually need to move the TR dequeue pointer we need to set the
correct cycle bit as well. Previously we used the trb pointer from the
last event received as a base, but this was changed in
commit 1f81b6d22a59 ("usb: xhci: Prefer endpoint context dequeue pointer")
to use the dequeue pointer from the endpoint context instead
It turns out some Asmedia controllers advance the dequeue pointer
stored in the endpoint context past the event triggering TRB, and
this messed up the way the cycle bit was calculated.
Instead of adding a quirk or complicating the already hard to follow cycle bit
code, the whole cycle bit calculation is now simplified and adapted to handle
event and endpoint context dequeue pointer differences.
Fixes: 1f81b6d22a59 ("usb: xhci: Prefer endpoint context dequeue pointer")

get_system_type() is not thread-safe on OCTEON. It uses static data,
also more dangerous issue is that it's calling cvmx_fuse_read_byte()
every time without any synchronization. Currently it's possible to get
processes stuck looping forever in kernel simply by launching multiple
readers of /proc/cpuinfo:
(while true; do cat /proc/cpuinfo > /dev/null; done) &
(while true; do cat /proc/cpuinfo > /dev/null; done) &
...
Fix by initializing the system type string only once during the early

Generic code may need to perform certain operations when EVA is
enabled, for example, configure the segmentation registers during
boot. In order to avoid using more CONFIG_EVA ifdefs in the arch code,
such functions will be added in this header instead.
Initially this header contains a macro which will be used by generic
code later on during VPEs configuration on secondary cores.
All it does is to call the platform specific EVA init code in case
EVA is enabled.

but it did not work as expected. The reason is the the scall64-o32
implementation differs compared to scall32-o32. In the former, the v0
(syscall number) register contains the absolute syscall number
(4000 + X) whereas in the latter it contains the relative syscall
number (X). Fix the code to avoid doing an extra addition, and load

The commit [5ee0f803cc3a: usbcore: don't log on consecutive debounce
failures of the same port] added the check of the reliable port, but
it also replaced the device argument to dev_err() wrongly, which leads
to a NULL dereference.
This patch restores the right device, port_dev->dev. Also, since
dev_err() itself shows the port number, reduce the port number shown
in the error message, essentially reverting to the state before the
commit 5ee0f803cc3a.
[The fix suggested by Hannes, and the error message cleanup suggested
by Alan Stern]

In preemptible kernel, only TIF_USEDFPU flag is reliable to distinguish
whether _init_fpu()/_restore_fp() is needed. Because the value of the
CP0_Status.CU1 isn't changed during preemption.
