The macb driver only handle PHY description through platform_data
(macb_platform_data).
Thus, when using dt you cannot define phy properties like phy address or
phy irq pin.
This patch makes use of the of_mdiobus_register to add support for
phy device definition using dt.

init_syscall_trace() can only be called during kernel bootup only, so we can
mark it and the functions it calls as __init.

There are several tracepoints (mostly in RCU), that reference a string
pointer and uses the print format of "%s" to display the string that
exists in the kernel, instead of copying the actual string to the
ring buffer (saves time and ring buffer space).

Do not allocate a port to new device or process URB when its status is

On most ARM systems the per-cpu clockevents are truly per-cpu in
the sense that they can't be controlled on any other CPU besides
the CPU that they interrupt. If one of these clockevents were to
become a broadcast source we will run into a lot of trouble
because the broadcast source is enabled on t

On some ARM systems there are two sets of per-cpu timers: the TWD
timers and the global timers. The TWD timers are rated at 350 and
the global timers are rated at 300 but the TWD timers suffer from

Then later copy_process() denies CLONE_SIGHAND if the new process

_BCM_use_index and _BCL_use_index are never used and probably never will.

This is a security bug.
The follow-up will fix nsproxy to discourage this type of issue from

nsproxy.pid_ns is *not* the task's pid namespace. The name should clarify
that.
This makes it more obvious that setns on a pid namespace is weird --
it won't change the pid namespace shown in procfs.

The gadget strings table should be null terminated.
usb_gadget_get_string() loops through the table
expecting a null at the end of the list.

Soft offline code expects that MIGRATE_ISOLATE is set on the target page
only during soft offlining work. But currenly it doesn't work as expected
when get_any_page() fails and returns negative value. In the result, end
users can have unexpectedly isolated pages. This patch just fixes it.
