Here's a bugfix for orion5x. Without this, PCI doesn't initialize properly
because of too small coherent pool to cover the allocations needed.
A similar fix has already been done on kirkwood.

The userspace part of UML uses the asm-offsets.h generator mechanism to
create definitions for UM_KERN_<LEVEL> that match the in-kernel
KERN_<LEVEL> constant definitions.
As of commit 04d2c8c83d ("printk: convert
the format for KERN_<LEVEL> to a 2 byte pattern"), KERN_<LEVEL> is no
longer expanded to the literal '"<LEVEL>"', but to '"\001" "LEVEL"', i.e.
it contains two parts.
However, the combo of DEFINE_STR() in
arch/x86/um/shared/sysdep/kernel-offsets.h and sed-y in Kbuild doesn't
support string literals consisting of multiple parts. Hence for all
UM_KERN_<LEVEL> definitions, only the SOH character is retained in the actual
definition, while the remainder ends up in the comment. E.g. in
include/generated/asm-offsets.h we get
#define UM_KERN_INFO "\001" /* "6" KERN_INFO */
instead of
#define UM_KERN_INFO "\001" "6" /* KERN_INFO */
This causes spurious '^A' output in some kernel messages:
Calibrating delay loop... 4640.76 BogoMIPS (lpj=23203840)
pid_max: default: 32768 minimum: 301

^AChecking that host ptys support output SIGIO...Yes
^AChecking that host ptys support SIGIO on close...No, enabling workaround
^AUsing 2.6 host AIO
NET: Registered protocol family 16
bio: create slab <bio-0> at 0
Switching to clocksource itimer
To fix this:
- Move the mapping from UM_KERN_<LEVEL> to KERN_<LEVEL> from
arch/um/include/shared/common-offsets.h to
arch/um/include/shared/user.h, which is preincluded for all userspace
parts,
- Preinclude include/linux/kern_levels.h for all userspace parts, to
obtain the in-kernel KERN_<LEVEL> constant definitions. This doesn't
violate the kernel/userspace separation, as include/linux/kern_levels.h
is self-contained and doesn't expose any other kernel internals.
- Remove the now unused STR() and DEFINE_STR() macros.

This patch (as1607) fixes a race that can occur if a USB host
controller is removed while a process is reading the
/sys/kernel/debug/usb/devices file.
The usb_device_read() routine uses the bus->root_hub pointer to
determine whether or not the root hub is registered. The is not a
valid test, because the pointer is set before the root hub gets
registered and remains set even after the root hub is unregistered and
deallocated. As a result, usb_device_read() or usb_device_dump() can
access freed memory, causing an oops.
The patch changes the test to use the hcd->rh_registered flag, which
does get set and cleared at the appropriate times. It also makes sure
to hold the usb_bus_list_lock mutex while setting the flag, so that
usb_device_read() will become aware of new root hubs as soon as they
are registered.
