* Add a referance to initramfs along side initrd.

When write() extends a file(i_size is increased) and fsync() is called,
change of inode must be written to journaling area through fsync().
But,currently the i_trans_id is not correctly updated when i_size is
increased. So fsync() does not kick the journal writer.
Reiserfs_file_write() already updates the transaction when blocks are
allocated, but the case when i_size increases and new blocks are not added
is not correctly treated.
Following patch fix this bug.

Remove the conflict between fscontext and context mount options. If
context= is specified without fscontext it will operate just as before, if
both are specified we will use mount point labeling and all inodes will get
the label specified by context=. The superblock will be labeled with the
label of fscontext=, thus affecting operations which check the superblock
security context, such as associate permissions.

Problem:
In the function __migrate_task(), deactivate_task() followed by
activate_task() is used to move the task from one run queue to
another. This has two undesirable effects:
1. The task's priority is recalculated. (Nowhere else in the
scheduler code is the priority recalculated for a change of CPU.)
2. The task's time stamp is set to the current time. At the very least,
this makes the adjustment of the time stamp before the call to
deactivate_task() redundant but I believe the problem is more serious
as the time stamp now holds the time of the queue change instead of
the time at which the task was woken. In addition, unless dest_rq is
the same queue as "current" is on the time stamp could be inaccurate
due to inter CPU drift.
Solution:
Replace the call to activate_task() with one to __activate_task().

It's useful to be able to turn off CONFIG_HOTPLUG for compile-coverage testing

It's only turnable offable if CONFIG_EMBEDDED anyway. So let's make those

Several issues noticed/fixed:
- We cannot reliably block in link_pipe() while holding both input and output
mutexes. So do preparatory checks before locking down both mutexes and doing
the link.
- The ipipe->nrbufs vs i check was bad, because we could have dropped the
ipipe lock in-between. This causes us to potentially look at unknown
buffers if we were racing with someone else reading this pipe.

[PATCH] Only the first two bits in bio->bi_rw and rq->flags match
[PATCH] blktrace: readahead support
[PATCH] blktrace: fix barrier vs sync typo
The following patch gets rid of CONFIG_TSI108_BRIDGE. I add UPIO_TSI to
handle IIR and IER register in serial_in and serial_out.
(1) the reason to rewrite serial_in:
TSI108 rev Z1 version ERRATA. Reading the UART's Interrupt
Identification Register (IIR) clears the Transmit Holding Register
Empty (THRE) and Transmit buffer Empty (TEMP) interrupts even if they
are not enabled in the Interrupt Enable Register (IER). This leads to
loss of the interrupts. Interrupts are not cleared when reading UART
registers as 32-bit word.
(2) the reason to rewrite serial_out:
Check for UART_IER_UUE bit in the autoconfig routine. This section
of autoconfig is excluded for Tsi108/109 because bits 7 and 6 are
reserved for internal use. They are R/W bits. In addition to
incorrect identification, changing these bits (from 00) will make
Tsi108/109 UART non-functional.

The patch below fixes serial console hangs as seen on IP22
machines. Typically, while booting, the machine hangs for ~1 minute
displaying "INIT: ", then the same thing happens again when init
enters in the designated runlevel and finally the getty process on
ttyS0 hangs indefinitely (though strace'ing it helps).
strace (-e raw=ioctl, otherwise the ioctl() translation is utterly
bogus) reveals that getty hangs on ioctl() 0x540f which happens to be
TCSETSW (I saw it hang on another console ioctl() but couldn't
reproduce that one).
A diff between ip22zilog and sunzilog revealed the following
differences:
1. the channel A flag being set on up.port.flags instead of up.flags
2. the channel A flag being set on what is marked as being channel B
3. sunzilog has a call to uart_update_timeout(port, termios->c_cflag, baud);
at the end of sunzilog_set_termios(), which ip22zilog lacks (on
purpose ?)
The patch below addresses point 1 and fixes the serial console hangs
just fine. However point 2 should be investigated by someone familiar
with the IP22 Zilog; it's probably OK as is but even if it is, a
comment in ip22zilog.c is badly needed.
Point 3 is left as an exercise for whoever feels like digging into
ip22zilog :)
These are the main obvious differences between ip22zilog and
sunzilog. Newer versions of sunzilog (Linus's git tree as of today)
are more close to ip22zilog as the sbus_{write,read}b have been
changed into simple {write,read}b, which shrinks the diff by a fair
amount. Resyncing both drivers should be doable in a few hours time
now for someone familiar with the IP22 Zilog hardware.

Linux mutexes and the debug code that that reference
acpi_os_get_thread_id() are happy with 0.
But the AML mutexes in exmutex.c expect a unique non-zero
number for each thread - as they track this thread_id
to permit the mutex re-entrancy defined by the ACPI spec.

Added the ACPI_PACKED_POINTERS_NOT_SUPPORTED macro to
support C compilers that do not allow the initialization
of address pointers within packed structures - even though
the hardware itself may support misaligned transfers. Some
of the debug data structures are packed by default to
minimize size.
Added an error message for the case where
acpi_os_get_thread_id() returns zero. A non-zero value is
required by the core ACPICA code to ensure the proper
operation of AML mutexes and recursive control methods.
The DSDT is now the only ACPI table that determines whether
the AML interpreter is in 32-bit or 64-bit mode. Not really
a functional change, but the hooks for per-table 32/64
switching have been removed from the code. A clarification
to the ACPI specification is forthcoming in ACPI 3.0B.
Fixed a possible leak of an Owner ID in the error
path of tbinstal.c acpi_tb_init_table_descriptor() and
migrated all table OwnerID deletion to a single place in
acpi_tb_uninstall_table() to correct possible leaks when using
the acpi_tb_delete_tables_by_type() interface (with assistance

semaphore associated with the method could be over-signaled
after multiple method invocations.

Currently struct scsi_cmnd has various fields that are used to backup
original data after the corresponding fields have been overridden for
EH commands. This means drivers can easily get at it and misuse it.
Due to the old_ naming this doesn't happen for most of them, but two
that have different names have been used wrong a lot (see previous
patch). Another downside is that they unessecarily bloat the scsi_cmnd
size.
This patch moves them onstack in scsi_send_eh_cmnd to fix those two
issues aswell as allowing future EH fixes like moving the EH command
submissions to use SG lists like everything else.
