x86-64: seccomp: fix 32/64 syscall hole

call. A 64-bit process make a 32-bit system call with int $0x80.
In both these cases under CONFIG_SECCOMP=y, secure_computing() will use

/* test case for seccomp circumvention on x86-64
There are two failure modes: compile with -m64 or compile with -m32.
The -m64 case is the worst one, because it does "chmod 777 ." (could
be any chmod call). The -m32 case demonstrates it was able to do
stat(), which can glean information but not harm anything directly.
A buggy kernel will let the test do something, print, and exit 1; a
fixed kernel will make it exit with SIGKILL before it does anything.

This fixes the problem when MAC address is set by ifconfig or by

This is problem when Xen daemon is running because it renames the device

netpoll: Add drop checks to all entry points
The netpoll entry checks are required to ensure that we don't
receive normal packets when invoked via netpoll. Unfortunately
it only ever worked for the netif_receive_skb/netif_rx entry
points. The VLAN (and subsequently GRO) entry point didn't
have the check and therefore can trigger all sorts of weird
problems.
This patch adds the netpoll check to all entry points.
I'm still uneasy with receiving at all under netpoll (which
apparently is only used by the out-of-tree kdump code). The
reason is it is perfectly legal to receive all data including
headers into highmem if netpoll is off, but if you try to do
that with netpoll on and someone gets a printk in an IRQ handler
you're going to get a nice BUG_ON.

one queued to its endpoint. That will cause musb_advance_schedule()
to block once it reaches 'struct musb_qh' with now empty URB list, so
URBs queued for other endpoints after the one being dequeued will not
be served.
Fix by unlinking the QH from the list except when it's already being
handled (typically by musb_giveback). Since a QH with an empty URB
list is now supposed to be freed, do that. And remove a now-useless

- Use clk_enable()/clk_disable() ... the "always enable USB clocks"
code this originally relied on has since been removed.
- Initialize the USB device only after the relevant I2C GPIOs are
available, so the host side can properly enable VBUS.
- Tweak init sequencing to cope with mainline's relatively late init
of the I2C system bus for power switches, transceivers, and so on.
Sanity tested on DM6664 EVM for host and peripheral modes; that system
