_BIF was returning buffer instead of a string since day 1 of ACPI.
Adding a warning for that is noble, but people don't like
when someone cries wolf in a production system.

This message happens when the package element list is longer than
the declared length of the package. Changed to an info message
because this condition is not actually an error. It is caused by
the BIOS attempting to truncate the package on the fly by adjusting
the package element count at the start of the package definition.

Converting some of the scheduler trace events to use the
TRACE_EVENT_TEMPLATE, DEFINE_EVENT and DEFINE_EVENT_PRINT helped to
save some space:
$ size kernel/sched.o-*
text data bss dec hex filename
79299 6776 2520 88595 15a13 kernel/sched.o-notrace
101941 11896 2584 116421 1c6c5 kernel/sched.o-templ
104779 11896 2584 119259 1d1db kernel/sched.o-trace
sched.o-notrace is without any tracepoints compiled
sched.o-templ is with this patch
sched.o-trace is the tracepoints before this patch
The trace events converted to DEFINE_EVENT:
sched_wakeup, sched_wakeup_new, sched_process_free, sched_process_exit,
and sched_stat_wait.
The trace events converted to DEFINE_EVENT_PRINT:
sched_stat_sleep and sched_stat_iowait.
Note, since the TRACE_EVENT_TEMPLATE always uses a print, the
sched_stat_wait print format is defined in the template and this
template is used by sched_stat_sleep and sched_stat_iowait. But the
later two override the print format.

After creating the TRACE_EVENT_TEMPLATE I started to look at other
trace points to see what duplication was made. I noticed that there
are several trace points where they are almost identical except for
the name and the output format. Since TRACE_EVENT_TEMPLATE was successful
in bringing down the size of trace events, I added a DEFINE_EVENT_PRINT.
DEFINE_EVENT_PRINT is used just like DEFINE_EVENT is. That is, the
DEFINE_EVENT_PRINT also uses a TRACE_EVENT_TEMPLATE, but it allows the
developer to overwrite the print format. If there are two or more
TRACE_EVENTS that are identical except for the name and print, then
they can be converted to use a TRACE_EVENT_TEMPLATE. Since the
TRACE_EVENT_TEMPLATE already does the print output, the first trace event
would have its print format held in the TRACE_EVENT_TEMPLATE and
be defined with a DEFINE_EVENT. The rest will use the DEFINE_EVENT_PRINT
and override the print format.
Converting the sched trace points to both DEFINE_EVENT and
DEFINE_EVENT_PRINT. Five were converted to DEFINE_EVENT and two were
converted to DEFINE_EVENT_PRINT.
I was able to get the following:
$ size kernel/sched.o-*
text data bss dec hex filename
79299 6776 2520 88595 15a13 kernel/sched.o-notrace
101941 11896 2584 116421 1c6c5 kernel/sched.o-templ
104779 11896 2584 119259 1d1db kernel/sched.o-trace
sched.o-notrace is the scheduler compiled with no trace points.
sched.o-templ is with the use of DEFINE_EVENT and DEFINE_EVENT_PRINT
sched.o-trace is the current trace events.

SMB writes are sent with a starting offset and length. When the server
supports the newer SMB trans2 posix open (rather than using the SMB
NTCreateX) a file can be opened with SMB_O_APPEND flag, and for that
case Samba server assumes that the offset sent in SMBWriteX is unneeded
since the write should go to the end of the file - which can cause
problems if the write was cached (since the beginning part of a
page could be written twice by the client mm). Jeff suggested that
masking the flag on posix open on the client is easiest for the time
being. Note that recent Samba server also had an unrelated problem with
SMB NTCreateX and append (see samba bugzilla bug number 6898) which
should not affect current Linux clients (unless cifs Unix Extensions
are disabled).
The cifs client did not send the O_APPEND flag on posix open
before 2.6.29 so the fix is unneeded on early kernels.
In the future, for the non-cached case (O_DIRECT, and forcedirectio mounts)
it would be possible and useful to send O_APPEND on posix open (for Windows
case: FILE_APPEND_DATA but not FILE_WRITE_DATA on SMB NTCreateX) but for
cached writes although the vfs sets the offset to end of file it
may fragment a write across pages - so we can't send O_APPEND on
open (could result in sending part of a page twice).

There are some places in the kernel that define several tracepoints and
they are all identical besides the name. The code to enable, disable and
record is created for every trace point even if most of the code is
identical.
This patch adds TRACE_EVENT_TEMPLATE that lets the developer create
a template TRACE_EVENT and create trace points with DEFINE_EVENT, which
is based off of a given template. Each trace point used by this
will share most of the code, and bring down the size of the kernel
when there are several duplicate events.
Usage is:
TRACE_EVENT_TEMPLATE(name, proto, args, tstruct, assign, print);
Which would be the same as defining a normal TRACE_EVENT.
To create the trace events that the trace points will use:
DEFINE_EVENT(template, name, proto, args) is done. The template
is the name of the TRACE_EVENT_TEMPLATE to use. The name is the
name of the trace point. The parameters proto and args must be the same
as the proto and args of the template. If they are not the same,
then a compile error will result. I tried hard removing this duplication
but the C preprocessor is not powerful enough (or my CPP magic
experience points is not at a high enough level) to not need them.
A lot of trace events are coming in with new XFS development. Most of
the trace points are identical except for the name. The following shows
the advantage of having TRACE_EVENT_TEMPLATE:
$ size fs/xfs/xfs.o.*
text data bss dec hex filename
452114 2788 3520 458422 6feb6 fs/xfs/xfs.o.old
638482 38116 3744 680342 a6196 fs/xfs/xfs.o.template
996954 38116 4480 1039550 fdcbe fs/xfs/xfs.o.trace
xfs.o.old is without any tracepoints.
xfs.o.template uses the new TRACE_EVENT_TEMPLATE.
xfs.o.trace uses the current TRACE_EVENT macros.

RSC and LOM devices have fixed speed settings.
We already had some code to match and handle "rsc" named devices on
E250 systems, but we also have to handle 'rsc-console', 'rsc-control',
and 'lom-console'.
Also, in order to get this right regardless of what 'output-device'
happens to be, explicitly pass the UART device node pointer to this
routine.

This tells the logic to ignore the line match when deciding whether the
device is the OpenFirmware specified console device or not.
This is going to be used in the SU driver for rsc-console detection.
There is probably a better way to handle this, but this is the least
intrusive solution for now which we can validate won't break any other
cases.

Other Sun serial drivers do not do this, and if we keep it this way
it ends up registering all serial devices as consoles rather than
just the one which we explicitly register via sunserial_console_match()
which uses add_preferred_console().
