It's desirable for allnconfig and tinyconfig targets to result in the
least amount of code possible. DISABLE_DEV_COREDUMP exists as a way to
switch off DEV_COREDUMP regardless if any drivers select
WANT_DEV_COREDUMP.
This patch renames the option to ENABLE_DEV_COREDUMP and setting it to
'n' (as in allnconfig or tinyconfig) will effectively disable device
coredump.

There is a race condition when removing glue directory.
It can be reproduced in following test:
path 1: Add first child device
device_add()
get_device_parent()
/*find parent from glue_dirs.list*/
list_for_each_entry(k, &dev->class->p->glue_dirs.list, entry)
if (k->parent == parent_kobj) {
kobj = kobject_get(k);
break;
}
....
class_dir_create_and_add()
path2: Remove last child device under glue dir
device_del()
cleanup_device_parent()
cleanup_glue_dir()
kobject_put(glue_dir);
If path2 has been called cleanup_glue_dir(), but not
call kobject_put(glue_dir), the glue dir is still
in parent's kset list. Meanwhile, path1 find the glue
dir from the glue_dirs.list. Path2 may release glue dir
before path1 call kobject_get(). So kernel will report
the warning and bug_on.
This is a "classic" problem we have of a kref in a list
that can be found while the last instance could be removed
at the same time.
This patch reuse gdp_mutex to fix this race condition.
The following calltrace is captured in kernel 3.4, but
the latest kernel still has this bug.

Add new quirk for devices that cannot handle control-line state
requests.
Note that we currently send these requests to all devices, regardless of
whether they claim to support it, but that errors are only logged if
support is claimed.
Since commit 0943d8ead30e ("USB: cdc-acm: use tty-port dtr_rts"), which
only changed the timings for these requests slightly, this has been
reported to cause occasional firmware crashes on Simtec Electronics
Entropy Key devices after re-enumeration. Enable the quirk for this
device.

Commit f95499c3030f ("n_tty: Don't wait for buffer work in read() loop")
introduces a race window where a pty master can be signalled that the pty
slave was closed before all the data that the slave wrote is delivered.
Commit f8747d4a466a ("tty: Fix pty master read() after slave closes") fixed the
problem in case of n_tty_read, but the problem still exists for n_tty_poll.
This can be seen by running 'for ((i=0; i<100;i++));do ./test.py ;done'
where test.py is:
import os, select, pty
(pid, pty_fd) = pty.fork()
if pid == 0:
os.write(1, 'This string should be received by parent')
else:
poller = select.epoll()
poller.register( pty_fd, select.EPOLLIN )
ready = poller.poll( 1 * 1000 )
for fd, events in ready:
if not events & select.EPOLLIN:
print 'missed POLLIN event'
else:
print os.read(fd, 100)
poller.close()
The string from the slave is missed several times.
This patch takes the same approach as the fix for read and special cases
this condition for poll.
Tested on 3.16.

The previous limits were estimated locally in a single step
basead on bound values, however it was not correct since
when given certain scatterlist the function nx_build_sg_lists
was consuming more sg entries than allocated causing a
memory corruption and crashes.
e.g.: in the worst case we could have one sg entry for a single byte.
This patch fixes it modifying the logic of the bound limit
moving it to nx_sg_build_lists and set a correct sg_max limit,
adding a trim function to ensure the bound in sg_list. Also fixing
nx_build_sg_list NULL and untreated return in case of overflow.

If PM_RUNTIME is enabled, it is easy to trigger the following backtrace
on pxa2xx hosts:

This happens because suspend function tries to disable a clock that is
already disabled by runtime_suspend callback. Add if
(!pm_runtime_suspended()) checks to suspend/resume path.
Fixes: 7d94a505858 (spi/pxa2xx: add support for runtime PM)

The info pointer points to an uninitialized kmalloced space.
If a device doesn't have clk property, then info->clk may
have unpredicated value and cause call trace. So use kzalloc
to make sure it is NULL initialized.

We can call this function for a dummy console that doesn't support
setting the font mapping, which will result in a null ptr BUG. So check
for this case and return error for consoles w/o font mapping support.

The calculation of value quot for highspeed register set to three
was wrong. This patch fixes the calculation so that the serial port
for baudrates bigger then 576000 baud is working correctly.
