e67aa27a61 intel-agp: Fix i830 mask variable that changed with G33 support
The mask on i830 should be 0x70 always, later chips 0xF0 should be okay.

248bdd5efc pci: fix unterminated pci_device_id lists
Fix a couple drivers that do not correctly terminate their pci_device_id
lists.  This results in garbage being spewed into modules.pcimap when the
module happens to not have 28 NULL bytes following the table, and/or the
last PCI ID is actually truncated from the table when calculating the
modules.alias PCI aliases, cause those unfortunate device IDs to not
auto-load.

4191ba26da mspec: handle shrinking virtual memory areas
The shrinking of a virtual memory area that is mmap(2)'d to a memory
special file (device drivers/char/mspec.c) can cause a panic.

If the mapped size of the vma (vm_area_struct) is very large, mspec allocates
a large vma_data structure with vmalloc(). But such a vma can be shrunk by
an munmap(2).  The current driver uses the current size of each vma to
deduce whether its vma_data structure was allocated by kmalloc() or vmalloc().
So if the vma was shrunk it appears to have been allocated by kmalloc(),
and mspec attempts to free it with kfree().  This results in a panic.

This patch avoids the panic (by preserving the type of the allocation) and
also makes mspec work correctly as the vma is split into pieces by the
munmap(2)'s.

All vma's derived from such a split vma share the same vma_data structure that
represents all the pages mapped into this set of vma's.  The mpec driver
must be made capable of using the right portion of the structure for each
member vma.  In other words, it must index into the array of page addresses
using the portion of the array that represents the current vma. This is
enabled by storing the vma group's vm_start in the vma_data structure.

The shared vma_data's are not protected by mm->mmap_sem in the fork() case
so the reference count is left as atomic_t.

f629307c85 tty: termios locking functions break with new termios type
I ran into a few problems.

n_tty_ioctl() for instance:

drivers/char/tty_ioctl.c:799: error: $,1rxstruct termios$,1ry has no
member named $,1rxc_ispeed$,1ry

This is calling the copy interface that is supposed to be using
a termios2 when the new interfaces are defined, however:

	case TIOCGLCKTRMIOS:
		if (kernel_termios_to_user_termios((struct termios __user *)arg, real_tty->termios_locked))
			return -EFAULT;
		return 0;

This is going to write over the end of the userspace
structure by a few bytes, and wasn't caught by you yet
because the i386 implementation is simply copy_to_user()
which does zero type checking.

3b2b64fd31 Do not use the ia64 clocksource on non-ia64 architectures
The HPET clocksource in drivers/char/hpet.c was written as generic code
for ia64, but it is not yet ready to replace the native HPET clocksource
implementations that the i386/x86-64 architectures use.

On x86[-64], trying to register this clocksource results in potentially
multiple hpet-based clocksources being registered, and if the ia64 one
is chosen on x86_64 some users have experienced hangs.

Eventually all three architectures may end up using the same code, but
that is not the case right now.

42fd552e86 fix serial buffer memory leak
Patch c5c34d4862 (tty: flush flip buffer on
ldisc input queue flush) introduces a race condition which can lead to memory
leaks.

The problem can be triggered when tcflush() is called when data are being
pushed to the line discipline driver by flush_to_ldisc().

flush_to_ldisc() releases tty->buf.lock when calling the line discipline
receive_buf function. At that poing tty_buffer_flush() kicks in and sets both
tty->buf.head and tty->buf.tail to NULL. When flush_to_ldisc() finishes, it
restores tty->buf.head but doesn't touch tty->buf.tail. This corrups the
buffer queue, and the next call to tty_buffer_request_room() will allocate a
new buffer and overwrite tty->buf.head. The previous buffer is then lost
forever without being released.

(Thanks to Laurent for the above text, for finding, disgnosing and reporting
the bug)

- Use tty->flags bits for the flush status.

- Wait for the flag to clear again before returning

- Fix the doc error noted

- Fix flush of empty queue leaving stale flushpending

80cd69203c ipmi: Fix mem leak in try_init_dmi()
This is only called at init time and only happens if the BIOS screws
something up, so the leak is slight and it is probably not worth sending to
2.6.22.x.  The driver would not initialize the interface in the case, and I
have no reports of this happening.  I have booted and run tests on a system
with this patch.  Note that the original patch was munged by the mailer,
here's a new one.

If we ever hit the "default:" case in the switch in try_init_dmi(),
then we'll leak the storage allocated with kzalloc() and assigned
to 'info'.

647e50f383 [WATCHDOG] Fix pcwd_init_module crash
Fix for the problem detected by Ingo Molnar:
enabling CONFIG_PCWATCHDOG=y crashes bzImage bootup.

The reason for this can be found in drivers/makefile
We first do:
obj-y                           += char/
and later we do:
obj-y                           += base/ block/ misc/ mfd/ net/ media/

So if we put a platform or isa or usb bus driver in char/watchdog
(which is called from the Makefile in drivers/char/Makefile)
then we didn't have the different device drivers initialized yet
(they are in drivers/base and drivers/usb and ...)

This fix makes sure that we compile the watchdog drivers after
drivers/base, drivers/misc, drivers/pci and drivers/usb.
We also do the compile after hwmon because in the future the
watchdog temperature support will use the hwmon system.

a51b34593f agp: don't lock pages
AGP should not need to lock pages. They are not protecting any race
because there is no lock_page calls, only SetPageLocked.

This is causing hangs with d00806b183.

190644e180 Fix "use after free" / "double free" bug in ati_create_gatt_pages / ati_free_gatt_pages
Hi,

Coverity spotted a "use after free" bug in
drivers/char/agp/ati-agp.c::ati_create_gatt_pages().

The same one that was in
  drivers/char/agp/amd-k7-agp.c::amd_create_gatt_pages()

The problem is this:
       If "entry = kzalloc(sizeof(struct ati_page_map), GFP_KERNEL);"
fails, then there's a loop in the function to free all entries
allocated so far and break out of the allocation loop. That in itself
is pretty sane, but then the (now freed) 'tables' is assigned to
ati_generic_private.gatt_pages and 'retval' is set to -ENOMEM which
causes ati_free_gatt_pages(); to be called at the end of the function.
The problem with this is that ati_free_gatt_pages() will then loop
'ati_generic_private.num_tables' times and try to free each entry in
tables[] - this is bad since tables has already been freed and
furthermore it will call kfree(tables) at the end - a double free.

This patch removes the freeing loop in ati_create_gatt_pages() and
instead relies entirely on the call to ati_free_gatt_pages() to free
everything we allocated in case of an error. It also sets
ati_generic_private.num_tables to the actual number of entries
allocated instead of just using the value passed in from the caller -
this ensures that ati_free_gatt_pages() will only attempt to free
stuff that was actually allocated.

Note: I'm in no way intimate with this code and I have no way to
actually test this patch (besides compile test it), so while I've
tried to be careful in reading the code and make sure the patch
does the right thing an ACK from someone who actually knows the
code in-depth would be very much appreciated.
