usb: gadget: composite: introduce usb_gstrings_attach()
The USB strings don't (yet) fully work in multiple configs/gadget
environment. The string id is assigned to the descriptor and the struct
usb_strings. We create a copy of the individual descriptor so we don't
clash if we use a function more than once. However, we have only one
struct usb_string for each string.
Currently each function which is used multiple times checks for
"id != 0" and only assigns string ids if it did not happen yet. This
works well if we use the same function multiple times as long as we do
it within the "one" gadget we have. Trouble starts once we use the same
function in a second gadget.
In order to solve this I introduce usb_gstrings_attach(). This function will
crate a copy all structs except for the strings which are not copied.
After the copy it will assign USB ids and attach it to cdev.

usb: gadget: allocate & giveback serial ports instead hard code them
This patch removes gserial_setup() and gserial_cleanup() and adds
gserial_alloc_line() and gserial_free_line() to replace them.
The initial setup of u_serial happens now on module load time. A
maximum of four TTY ports can be requested which is the current limit.
In theory we could extend this limit, the hard limit is the number of
available endpoints.
alloc_tty_driver() is now called at module init time with the max
available ports. The per-line footprint here is on 32bit is 3 * size of
pointer + 60 bytes (for cdevs).
The remaining memory (struct gs_port) is allocated once a port is
requested.
With this change it is possible to load g_multi and g_serial at the same
time. GS0 receives the module that is loaded first, GS1 is received by
the next module and so on. With the configfs interface the port number
can be exported and the device node is more predictable. Nothing changes

usb: gadget: add some infracture to register/unregister functions
This patch provides an infrastructure to register & unregister a USB
function. This allows to turn a function into a module and avoid the
'#include "f_.*.c"' magic and we get a clear API / cut between the bare
gadget and its functions.
The concept is simple:
Each function defines the DECLARE_USB_FUNCTION_INIT macro whith an unique
name of the function and two allocation functions.
- one to create an "instance". The instance holds the current configuration
set. In case there are two usb_configudations with one function there will
be one instance and two usb_functions
- one to create an "function" from the instance.
The name of the instance is used to automaticaly load the module if it the
instance is not yet available.
The usb_function callbacks are slightly modified and extended:
- usb_get_function()
creates a struct usb_function inclunding all pointers (bind,
unbind,…). It uses the "instance" to map its configuration. So we can
have _two_ struct usb_function, one for each usb_configuration.
- ->unbind()
Since the struct usb_function was not allocated in ->bind() it should
not kfree()d here. This function should only reverse what happens in
->bind() that is request cleanup and the cleanup of allocated
descriptors.
- ->free_func()
a simple kfree() of the struct usb_function

If the device is the target of the setup request then we forward it to the

In case of the sourcesink function the requests are function specific

This patch introduces a setup wrapper at configuration level which
forwards the request to the function. By using this wrapper we can keep

nokia_bind_config() tries to clean up which is IMHO the right thing to
do. Leaving things as-is and hoping that its unbind() will clean it up
is kinda backwards. Especially since the bind function never succeeded so
it can't know how much it needs to clean up.

With commit 384a290 (ARM: gic: use a private mapping for CPU target
interfaces), wake-up IPIs now go to all cores as the gic cpu interface
numbering may not follow core numbering. This broke secondary boot on
highbank since the boot address was already set for all secondary cores,
this caused all cores to boot before the kernel was ready.
Fix this by moving the setting of the jump address to
highbank_boot_secondary instead of highbank_smp_prepare_cpus and
highbank_cpu_die. Also, clear the address when we boot. This prevents
cores from booting before they are actually triggered and is also necessary

added a "choice" to the sctp Kconfig file. It introduced a bug which
led to an infinite loop when while running "make oldconfig".
The problem is that the wrong symbol was defined as the default value

drm/radeon: add quirk for d3 delay during switcheroo poweron for apple macbooks

I did some testing, dumping the difference in ms between first succesful switch

the device is re-enabled through vga-switcheroo.
So bump the re-enable d3 delay to 20 ms to handle this, which fixes msi not working

tcp: fix MSG_SENDPAGE_NOTLAST logic
commit
35f9c09fe9c72e (tcp: tcp_sendpages() should call tcp_push() once)
added an internal flag : MSG_SENDPAGE_NOTLAST meant to be set on all
frags but the last one for a splice() call.
The condition used to set the flag in pipe_to_sendpage() relied on
splice() user passing the exact number of bytes present in the pipe,
or a smaller one.
But some programs pass an arbitrary high value, and the test fails.
The effect of this bug is a lack of tcp_push() at the end of a
splice(pipe -> socket) call, and possibly very slow or erratic TCP
sessions.
We should both test sd->total_len and fact that another fragment
is in the pipe (pipe->nrbufs > 1)
Many thanks to Willy for providing very clear bug report, bisection
and test programs.
