serial: 8250: fix shared interrupts issues with SMP and RT kernels
With SMP kernels _irqsave spinlock disables only local interrupts, while
the shared serial interrupt could be assigned to the CPU that is not
currently starting up the serial port.
This might cause issues because serial8250_startup() routine issues
IRQ-triggering operations before registering the port in the IRQ chain
(though, this is fine to do and done explicitly because we don't want to
process any interrupts on the port startup).
With RT kernels and preemptable hardirqs, _irqsave spinlock does not
disable local hardirqs, and the bug could be reproduced much easily:
$ cat /dev/ttyS0 &
$ cat /dev/ttyS1
irq 42: nobody cared (try booting with the "irqpoll" option)

Disabling IRQ #42
After this, all serial ports on the given IRQ are non-functional.
To fix the issue we should explicitly disable shared IRQ before
issuing any IRQ-triggering operations.
I also changed spin_lock_irqsave to the ordinary spin_lock, since it
seems to be safe: chain does not contain new port (yet), thus nobody
will interfere us from the ISRs.

usb_serial: API all change
USB serial likes to use port->tty back pointers for the real work it does and
to do so without any actual locking. Unfortunately when you consider hangup
events, hangup/parallel reopen or even worse hangup followed by parallel close
events the tty->port and port->tty pointers are not guaranteed to be the same
as port->tty is the active tty while tty->port is the port the tty may or
may not still be attached to.
So rework the entire API to pass the tty struct. For console cases we need
to pass both for now. This shows up multiple drivers that immediately crash
with USB console some of which have been fixed in the process.
Longer term we need a proper tty as console abstraction

execve filename: document and export via auxiliary vector
The Linux kernel puts the filename argument of execve() into the new
address space. Many developers are surprised to learn this. Those who
know and could use it, object "But it's not documented."
Those who want to use it dislike the expression
(char *)(1+ strlen(env[-1+ n_env]) + env[-1+ n_env])
because it requires locating the last original environment variable,
and assumes that the filename follows the characters.
This patch documents the insertion of the filename, and makes it easier
to find by adding a new tag AT_EXECFN in the ElfXX_auxv_t; see <elf.h>.
In many cases readlink("/proc/self/exe",) gives the same answer. But if
all the original pages get unmapped, then the kernel erases the symlink
for /proc/self/exe. This can happen when a program decompressor does a
good job of cleaning up after uncompressing directly to memory, so that
the address space of the target program looks the same as if compression
had never happened. One example is http://upx.sourceforge.net .
One notable use of the underlying concept (what path containED the
executable) is glibc expanding $ORIGIN in DT_RUNPATH. In practice for
the near term, it may be a good idea for user-mode code to use both
/proc/self/exe and AT_EXECFN as fall-back methods for each other.
/proc/self/exe can fail due to unmapping, AT_EXECFN can fail because it
won't be present on non-new systems. The auxvec or {AT_EXECFN}.d_val
also can get overwritten, although in nearly all cases this would be the
result of a bug.
The runtime cost is one NEW_AUX_ENT using two words of stack space. The
underlying value is maintained already as bprm->exec; setup_arg_pages()
in fs/exec.c slides it for stack_shift, etc.

always enable FW_LOADER unless EMBEDDED=y
James Bottomley recently discovered that we have

actually causing build errors for built-in users with
CONFIG_FW_LOADER=m.
But now missing selects on FW_LOADER are no longer visible at
compile-time at all and can become runtime problems.
FW_LOADER is infrastructure with relatively small codesize we can safely
enable for everyone, and only for people who really need small kernels
(and can be expected to know what they are doing) it matters being able
to disable it.
This patch therefore always sets FW_LOADER=y and allows users only to
disable it with EMBEDDED=y.
As a bonus, we can then get rid of all "select FW_LOADER" plus the due
to it required "depends on HOTPLUG" which removes some complexity from

sysfs: don't call notify_change
sysfs_chmod_file() calls notify_change() to change the permission bits
on a sysfs file. Replace with explicit call to sysfs_setattr() and
fsnotify_change().
This is equivalent, except that security_inode_setattr() is not
called. This function is called by drivers, so the security checks do
not make any sense.

sysdev: fix debugging statements in registration code.
The systdev_class_register() and sysdev_register() functions have
pr_debug() statements which are enabled when the user selects the
driver core debug. Both of these routines do not produce the
correct output, as they make assumptions about data which has not
been initialised.
In sysdev_class_register() the code uses the kobject_name(&cls->kset.kobj)
at the start of the function, but this is not setup until later in the
same call. Change this to use cls->name which is passed in from the caller.
The sysdev_register() function tries to get the name of the sysdev by
kobject_name(&sysdev->kobj), but that isn't setup until later in the same
function so change this message to use the name of the sysdev's class and
add another message once the name is initialised.
