The initial physical address was one too low for the outputs.
E.g. if 1.0.0.0 was expected, then it was set to 0.0.0.0, and
2.0.0.0 became 1.0.0.0.

Due to unknown reason, H6 needs larger intraprediction buffer for 4K

The enum containing the *_PARTITION symbolic names is only relevant
for the partition parser. More specifically most values are MSDOS
partition table system indicators and thus should go straight into
msdos.c. One value is only used by the sun partition parser, and the
sun and sgi partition parsers use the same value as the x86 Linux
RAID indicator to also indicate RAID autodetection. Duplicate them
in sun.c and sgi.c given that the different partition types use
entirely different values otherwise.

struct partition is the on-disk format of a MSDOS partition table entry.
Move it out of genhd.h into a new msdos_partition.h header and give it
a msdos_ prefix to avoid confusion.
Also move the magic number from block/partitions/msdos.h to the new
header so that it can be used by the SCSI drivers looking at the DOS
partition tables.

Currently on ACPI-enabled systems the USB interface device has no link to
the actual firmware node and thus drivers may not parse additional information
given in the table. The new feature, proposed here, allows to pass properties
or other information to the drivers.
The ACPI companion of the device has to be set for USB interface devices
to achieve above. Use ACPI_COMPANION_SET macro to set this.
Note, OF already does link of_node and this is the same for ACPI case.

Reading from a debugfs file at a nonzero position, without first reading
at position 0, leaks uninitialized memory to userspace.
It's a bit tricky to do this, since lseek() and pread() aren't allowed
on these files, and write() doesn't update the position on them. But
writing to them with splice() *does* update the position:
#define _GNU_SOURCE 1
#include <fcntl.h>
#include <stdio.h>
#include <unistd.h>
int main()
{
int pipes[2], fd, n, i;
char buf[32];
pipe(pipes);
write(pipes[1], "0", 1);
fd = open("/sys/kernel/debug/fault_around_bytes", O_RDWR);
splice(pipes[0], NULL, fd, NULL, 1, 0);
n = read(fd, buf, sizeof(buf));
for (i = 0; i < n; i++)
printf("%02x", buf[i]);
printf("\n");
}
Output:
5a5a5a5a5a5a5a5a5a5a5a5a5a5a5a5a5a5a5a5a5a5a5a30

Since commit "drivers: provide devm_platform_ioremap_resource()",
it was wrap platform_get_resource() and devm_ioremap_resource() as
single helper devm_platform_ioremap_resource(). but now, many drivers
still used platform_get_resource() and devm_ioremap_resource()
together in the kernel tree. The reason can not be replaced is they
still need use the resource variables obtained by platform_get_resource().
so provide this helper.

There are at least 3 models of the HP x2 10 models:
Bay Trail SoC + AXP288 PMIC
Cherry Trail SoC + AXP288 PMIC

Like on the other HP x2 10 models we need to ignore wakeup for ACPI GPIO
events on the external embedded-controller pin to avoid spurious wakeups
on the HP x2 10 CHT + AXP288 model too.
This commit adds an extra DMI based quirk for the HP x2 10 CHT + AXP288
model, ignoring wakeups for ACPI GPIO events on the EC interrupt pin
on this model. This fixes spurious wakeups from suspend on this model.
