Make flush_tlb_all_local take a void * so it doesn't have to be cast
when using on_each_cpu(). This becomes a problem when on_each_cpu
is a macro.

Same reasoning as commit 747c8a5594
but this time we're making uart_port flags a bitwise type - not
all of these flags correspond with the old ASYNC_ flags, so there
is the possibility for bugs if the wrong ASYNC_* constants are
used. Always use UPF_* constants for uart_port->flags.

The previous change found a bug in the serial SAK handling - because
we were looking for UPF_SAK set in uart_info->flags, we would never
raise a SAK condition. UPF_SAK is in uart_port->flags.

The potential for confusing the flags is fairly high. Make
uart_info's flags a bitwise type so sparse can check that the
right flag definitions are used with the right structure.

This patch resolves most of the problems with an SMP serial console race
with output via the tty path. At the end of the serial console print we
force enable the tx int in case we clobbered the tx interrupt status
racing between the console and tty output. That way the extra tx
interrupt causes the transmit path to restart not hang.
It also makes the serial console printk use the FIFO. This is neccessary
because some remote management devices fake serial console with FIFO and
are confused into sending one packet per character over ethernet when we
stall rather than filling the FIFO.
In order to preserve existing reliability semantics the function waits
for the serial queue to completely empty before returning.
Both of these problems were identified by a Red Hat partner.

While running "make menuconfig" and "make mrproper"
some people experienced that /dev/null suddenly changed
permissions or suddenly became a regular file.
The main reason was that /dev/null was used as output
to gcc in the check-lxdialog.sh script and gcc did
some strange things with the output file; in this
case /dev/null when it errorred out.
Following patch implements a suggestion
from Bryan O'Sullivan <bos@serpentine.com> to
use gcc -print-file-name=libxxx.so.
Also the Makefile is adjusted to not resolve value of
HOST_EXTRACFLAGS and HOST_LOADLIBES until they are actually used.
This prevents us from calling gcc when running make *clean/mrproper

Added 2006 copyright.
At SuSE's suggestion, enabled all error messages
without enabling function tracing, ie with CONFIG_ACPI_DEBUG=n
Replaced all instances of the ACPI_DEBUG_PRINT macro invoked at
the ACPI_DB_ERROR and ACPI_DB_WARN debug levels with
the ACPI_REPORT_ERROR and ACPI_REPORT_WARNING macros,
respectively. This preserves all error and warning messages
in the non-debug version of the ACPICA code (this has been
referred to as the "debug lite" option.) Over 200 cases
were converted to create a total of over 380 error/warning
messages across the ACPICA code. This increases the code
and data size of the default non-debug version by about 13K.
Added ACPI_NO_ERROR_MESSAGES flag to enable deleting all messages.
The size of the debug version remains about the same.

The compat layer timeout handling changes in:
9f72949f67
are busted. This is most easily seen with an X application
that uses sub-second select/poll timeout such as emacs. You
hit a key and it takes a second or so before the app responds.
The two ROUND_UP() calls upon entry are using {tv,ts}_sec where it
should instead be using {tv_usec,ts_nsec}, which perfectly explains

ARM entry-common.S needs to know syscall table size; in itself that would
not be a problem, but there's an additional constraint - some of the
instructions using it want a constant that would be a multiple of 4.
So we have to pad syscall table with sys_ni_syscall and that's where
the trouble begins. .rept pseudo-op wants a constant expression for
number of repetitions and subtraction of two labels (before and after
syscall table) doesn't always get simplified to constant early enough
for .rept. If labels end up in different frags, we lose. And while
the frag size is large enough (slightly below 4Kb), the syscall table
is about 1/3 of that. We used to get away with that, but the recent
changes had been enough to trigger the breakage.
Proper fix is simple: have a macro (CALL(x)) to populate the table
instead of using explicit .long x and the first time we include calls.S
have it defined to .equ NR_syscalls,NR_syscalls+1. Then we can find
the proper amount of padding on the first inclusion simply by looking
at NR_syscalls at that time. And that will be constant, no matter what.
Moreover, the same trick kills the need of having an estimate of padded
NR_syscalls - it will be calculated for free at the same time.

which isn't ready to merge and some of the "interesting" proc functionality
that needs reworking or just has no place in kernel. It requires no core

The goal is to merge further functionality only after the core code is

extras are really ready to merge.
