Fix the epca driver to permit epca_setup() to be invoked from the kernel cmdline
Fix the epca driver to call epca_setup() if digiepca=xxx is included on the
command line and the epca driver is built in.
epca_setup() used to be called from init/main.c in 2.2 kernels, but somewhere
along the way that call was removed but not replaced.

Fix the Stallion driver's putchar() and break_ctl() ops and iStallion's

Is it actually possible for putchar() or break_ctl() to be called with tty ==
NULL or can the check be discarded?
Should stl_write() be returning 0 if tty->driver_data is NULL or tx.buf is
NULL? Is this even possible?
I've made Stallion's functions return -EINVAL as stli_breakctl() if the checks

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.

usb-storage: revert DMA-alignment change for Wireless USB
This patch (as1110) reverts an earlier patch meant to help with
Wireless USB host controllers. These controllers can have bulk
maxpacket values larger than 512, which puts unusual constraints on
the sizes of scatter-gather list elements. However it turns out that
the block layer does not provide the support we need to enforce these
constraints; merely changing the DMA alignment mask doesn't help.
Hence there's no reason to keep the original patch. The Wireless USB
problem will have to be solved a different way.
In addition, there is a reason to get rid of the earlier patch. By
dereferencing a pointer stored in the ep_in array of struct
usb_device, the current code risks an invalid memory access when it
runs concurrently with device removal. The members of that array are
cleared before the driver's disconnect method is called, so it should
not try to use them.

usbfs: send disconnect signals when device is unregistered
USB device files are accessible in two ways: as files in usbfs and as
character device nodes. The two paths are supposed to behave
identically, but they don't. When the underlying USB device is
unplugged, disconnect signals are sent to processes with open usbfs
files (if they requested these signals) but not to processes with open
device node files.
This patch (as1104) fixes the bug by moving the disconnect-signalling
code into a common subroutine which is called from both paths.
Putting this subroutine in devio.c removes the only out-of-file
reference to struct dev_state, and so the structure's declaration can
be moved from usb.h into devio.c.
Finally, the new subroutine performs one extra action: It kills all
the outstanding async URBs. (I'd kill the outstanding synchronous
URBs too, if there was any way to do it.) In the past this hasn't
mattered much, because devices were unregistered from usbfs only
when they were disconnected. But now the unregistration can also
occur whenever devices are unbound from the usb_generic driver. At
any rate, killing URBs when a device is unregistered from usbfs seems
like a good thing to do.
