In contrast to 8250/8250_of, legacy_serial on powerpc does fill
(struct plat_serial8250_port). The reason is likely that it's done on
device_initcall(), not on probe. So, 8250_core is not yet probed.
Propagate value from platform_device on 8250 probe - in case powepc
legacy driver it's initialized on initcall, in case 8250_of it will be
initialized later on of_platform_serial_setup().

The SUPPORT_SYSRQ is messy: every .c source should define it before
including "serial_core.h" if sysrq is supported or struct uart_port will
differ in sizes. Also this prevents moving to serial_core.c functions:
uart_handle_sysrq_char(), uart_prepare_sysrq_char(),
uart_unlock_and_check_sysrq().
It doesn't save many bytes in the structure, and a better way to reduce
it's size would be making rs485 and iso7816 pointers.
Introduce `has_sysrq` member to be used by serial line drivers further.

The samsung_tty driver was trying to abuse the struct uart_port by using
two "empty" bytes for its own use. That's not ok, and was found by
removing those fields from the structure.
Move the variables into the port-specific structure, which is where
everything else for this port already is. There is no space wasted here
as there was an empty "hole" in the structure already for these bytes.

At the current place members those follow are:
: upf_t flags;
: upstat_t status;
: int hw_stopped;
: unsigned int mctrl;
: unsigned int timeout;
: unsigned int type;
: const struct uart_ops *ops;
Together, they give (*ops) 8-byte align on 64-bit platforms.
And `sysrq_ch` introduces 4-byte padding.
On the other side, above:
: struct device *dev;
: unsigned char hub6;
: unsigned char suspended;
: unsigned char unused[2];
: const char *name;
Adds another 4-byte padding.
Moving sysrq members just before `hub6` allows to save 8 bytes
per-uart_port on 64-bit platforms:
On my gcc, x86_64 sizeof(struct uart_port) goes from 528 to 520.

sysrq_toggle_support() can be called in parallel, in return calling
input_(un)register_handler(), which fortunately is safe to call
in parallel and regardless of registered/unregistered status of
sysrq_handler.
Remove sysrq_handler_registered as it doesn't have any function there
and may confuse reader about possible race.

The dbg() macro for the driver is not needed at all, all drivers should
use the common dynamic debugging infrastructure, not roll their own. So
delete the custom macro and convert the driver to use dev_dbg() instead,
providing a lot more information than the previous macro provided.

Orangefs has no open, and orangefs checks file permissions
on each file access. Posix requires that file permissions
be checked on open and nowhere else. Orangefs-through-the-kernel
needs to seem posix compliant.
The VFS opens files, even if the filesystem provides no
method. We can see if a file was successfully opened for
read and or for write by looking at file->f_mode.
When writes are flowing from the page cache, file is no
longer available. We can trust the VFS to have checked
file->f_mode before writing to the page cache.
The mode of a file might change between when it is opened
and IO commences, or it might be created with an arbitrary mode.
We'll make sure we don't hit EACCES during the IO stage by
using UID 0.

Possibly most interesting is Trond's fixes for some callback races that
were due to my incomplete understanding of rpc client shutdown.
Unfortunately at the last minute I've started noticing a new
intermittent failure to send callbacks. As the logic seems basically
correct, I'm leaving Trond's patches in for now, and hope to find a fix
in the next week so I don't have to revert those patches.
