Many binutils versions over the last year appear to silently build
assembler files with undefined constants, and able to successfully
create executables from such files.  The assembler appears to add
undefined symbols to the symbol table without any corresponding
relocation information.  Obviously this is bad news since the
resulting executable may not be what the programmer intended.
Work around the problem by forcing the linker to fail if there are
any undefined symbols in the final object(s).

Jeff Garzik notes that the previous cleanup highlights a bug:

Here's the fix..

The author apparently didn't understand that only the mach-default
include directory is included by fallback for header files only.  You
can't stick a .c file in mach-default and expect all subarchs to be able
to use it.

The correct fix is to put std_resources.c in the kernel directory and
give it its own Kconfig symbol for conditional compile so that subarchs
may choose to include it or not.

The last copy_from_user patch to the vicam driver broke compilation with
VICAM_DEBUG on.

There is also another copy_from_user missing in case VIDIOCSPICT. 

This fixes both issues.

There's a bug in the x86 code in that it sets the boot CPU to zero.

This isn't correct since some subarch's use physically indexed CPUs. 
However, subarchs have either set the boot cpu before irq_INIT() (or
just inherited the default zero from INIT_THREAD_INFO()), so it's safe
to believe current_thread_info()->cpu about the boot cpu.

This adds IOMMU support & IOMU virtual merging to the default g5 config.

This will not impair performances of machines that don't need the iommu
(the kernel will only enable it if you have more than 2Gb of RAM, though
you can explicitely enable it using a command line argument).

The current code has a subtle race where 2 hash PTEs can be inserted
for the same virtual address for a short period of time. There should
not be a stale one as the "old" one ultimately gets flushed, but the
architecture specifies that having two hash PTE is illegal and can
result in undefined behaviour.

This patch fixes it by never clearing the _PAGE_HASHPTE bit when
doing test_and_clear_{young,dirty}. That means that subsequent faults
on those pages will have a bit more overhead to "discover" that the
hash entry was indeed evicted.

It also adds a small optisation to avoid doing the atomic operation
and the hash flush in test_and_clear_dirty when the page isn't dirty
or when setting write protect while it's already set.

The new message queue interface needs the following patch to get it working
on s390 (31-bit, 64-bit and 31-bit compat).

This patch adds the TIF_SYSCALL_AUDIT option to the s390 ptrace interface.

Add POSIX mqueue support to x86-64.

Journalled quota support for ext3: The patch consists of two parts - ext3
changes and changes in generic quota code.  The main idea of the changes is
that a transaction is always started before any operation which changes quota
file and dirtifying of the quota causes its write to disk.  These two changes
assure that quota change is journalled into the same transaction as the file
change and hence after journal replay quota is consistent with the filesystem
state.  As during journal replay inodes from orphan list are deleted/truncated
we have to do quota_on before the replay of the orphan list - this problem is
solved by additional mount options to ext3 with quota file names and format.

Some changes in generic code were also needed to assure that quota structure
in file is always allocated and so ordinary quota operations (like
adding/deleting a block/inode) need only a few blocks from the transaction.

SUSv3 doesn't seem to specify one way or the other.  I don't have the POSIX
specs, and the old docs I have suggest that mq_open() creates an object
which is to be closed upon exec.

Jakub said:

  I think it is valid and required:

    http://www.opengroup.org/onlinepubs/007904975/functions/exec.html

    All open message queue descriptors in the calling process shall be
    closed, as described in mq_close()

  I'll add a new test for this into glibc testsuite.

Fix various bogons and outright lies.

	mq_notify (q, NULL)

and
	struct sigevent ev = { .sigev_notify = SIGEV_NONE };
	mq_notify (q, &ev)

are not the same thing in POSIX, yet the kernel treats them the same.  Only
the former makes the notification available to other processes immediately,
see

	http://www.opengroup.org/onlinepubs/007904975/functions/mq_notify.html

Without the patch below,

	http://sources.redhat.com/ml/libc-hacker/2004-04/msg00028.html

glibc test fails.

I looked at mq in Solaris and they behave the same in this regard as Linux
with this patch.  Kernel with this patch passes both Intel POSIX testsuite
(with testsuite fixes from Ulrich) and glibc mq testsuite.

Supersedes 1809/1

This adds support for the AMBA PL011 UART primecell, and moves the
existing AMBA UART support to indicate it covers the AMBA PL010
primecell.

Some TI cardbus bridges found in notebooks and PCI add-on cards are
uninitialized.  This means the interrupt mode and the interrupt routing
is wrong in most cases, ending up in non working PCI interrupts.

This makes the TI Yenta driver probe the PCI interrupt and adjust the
interrupt setting if no interrupts are delivered.  It's done in a safe
way, that doesn't hurt working setups.

Function 1 on two slot devices is handled differently from function 0
since both share the settings.

Okay, now while we are at fixing security holes, is there any chance we
can _finally_ get the attached patch in?

The Vicam USB driver in all Linux Kernels 2.6 mainline does not use the
copy_from_user function when copying data from userspace to kernel space,
which crosses security boundaries and allows local users to cause a denial
of service.

Already ACKed by Greg. Only complaint was inproper coding style which is done
with attached patch ;)

ciao, Marc

The directory .tmp_versions/ was deleted during make vmlinux.

This eliminated the list of modules used for moudles_install.
The effect was that the following scenario failed:

	make
	make install
	make modules_install

The solution is to only cleanup .tmp_versions when building modules.

It's very similar to a patch I submitted for the lm80 a few days ago.

Corrects isapnp_read_resources so that it gets MEM32 information properly.

This patch prevents /proc/bus/pnp/devices from requesting on-boot node
information.  Dynamic information is used instead.
