WARN_ON_ONCE() gives a stack trace including the full module list.
Having this in the kernel dump for the timeout case in the
generic netdev watchdog will help us see quicker which driver
is involved. It also allows us to collect statistics
and patterns in terms of which drivers have this event occuring.

Force constants in kernel/timeconst.h (except shift counts) to be 64 bits,
using U64_C() constructor macros, and eliminate constants that cannot
be represented at all in 64 bits. This avoids warnings with some gcc
versions.
Drop generating 64-bit constants, since we have no real hope of
getting a full set (operation on 64-bit values requires a 128-bit
intermediate result, which gcc only supports on 64-bit platforms, and
only with libgcc support on some.) Note that the use of these
constants does not depend on if we are on a 32- or 64-bit architecture.
This resolves Bugzilla 10153.

Add C99-style constructor macros for fixed types to
<asm-generic/int-*.h>. Since Linux uses names like "u64" instead of
"uint64_t", the constructor macros are called U64_C() instead of
UINT64_C() and so forth.
These macros allow specific sizes to be specified as
U64_C(0x123456789abcdef), without gcc issuing warnings as it will if
one writes (u64)0x123456789abcdef.
When used from assembly, these macros pass their argument unchanged.

calls scsi_add_host() with the device pointer set to NULL, and that
crashes code like arch/x64/kernel/pci-gart_64.c::need_iommu().

driver triggers a SCSI scan. In addition, the ability to change

single configuration change notification from the Firmware.

This patch (as1084b) fixes the way uhci-hcd handles polling and
remote wakeups for its root hubs. When remote wakeup is disabled,
neither interrupts nor polling should be enabled during a root-hub
suspend. Likewise, if interrupts are enabled during suspend then
polling isn't needed.
Furthermore the EGSM (Enter Global Suspend Mode) bit shouldn't be set
in the Command register unless remote wakeup is enabled. Apparently
some controllers will issue a remote-wakeup interrupt whenever EGSM
is on, even if Resume-Detect interrupts are supposedly disabled.
