Replace acpi_in_resume with a more general hack
to check irqs_disabled() on any kmalloc() from ACPI.
While setting (system_state != SYSTEM_RUNNING) on resume
seemed more general, Andrew Morton preferred this approach.

Make acpi_os_allocate() into an inline function to
allow /proc/slab_allocators to work.
Delete some memset() that could fault on allocation failure.

cm_sbs_sem is being downed (via acpi_ac_init->acpi_lock_ac_dir) before it is
initialised, with grave results.
- Make it a mutex
- Initialise it
- Make it static
- Clean other stuff up.
Thanks to Paul Drynoff <pauldrynoff@gmail.com> for reporting and testing.

Use thread info flags to track use of debug registers and IO bitmaps.
- add TIF_DEBUG to track when debug registers are active
- add TIF_IO_BITMAP to track when I/O bitmap is used
- modify __switch_to() to use the new TIF flags

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
from Lance Ortiz.)
Fixed a problem with Serialized control methods where the
semaphore associated with the method could be over-signaled
after multiple method invocations.
Fixed two issues with the locking of the internal
namespace data structure. Both the Unload() operator and
acpi_unload_table() interface now lock the namespace during
the namespace deletion associated with the table unload
(with assistance from Linn Crosetto.)
Fixed problem reports (Valery Podrezov) integrated: -
Eliminate unnecessary memory allocation for CreateXxxxField

Fixed problem reports (Fiodor Suietov) integrated: -

Use "+m" rather than a combination of "=m" and "m" for improved clarity
and consistency.
This also fixes some inlines that incorrectly didn't tell the compiler
that they read the old value at all, potentially causing the compiler to
generate bogus code. It appear that all of those potential bugs were
hidden by the use of extra "volatile" specifiers on the data structures
in question, though.

Certain subsystems in the stack (e.g., netfilter) can break the partial
checksum on GSO packets. Until they're fixed, this patch allows this to
work by recomputing the partial checksums through the GSO mechanism.
Once they've all been converted to update the partial checksum instead of
clearing it, this workaround can be removed.

This patch adds the wrapper function skb_is_gso which can be used instead
of directly testing skb_shinfo(skb)->gso_size. This makes things a little

ok this is a real potential deadlock in a way, it takes two locks of 2
skbuffs without doing any kind of lock ordering; I think the following
patch should fix it. Just sort the lock taking order by address of the
skb.. it's not pretty but it's the best this can do in a minimally
invasive way.

"return -err" and blindly inheriting the error code in the netlink
failure exception handler causes errors codes to be returned as

The TCA_ACT_KIND attribute is used without checking its
availability when dumping actions therefore leading to a
value of 0x4 being dereferenced.
The use of strcmp() in tc_lookup_action_n() isn't safe
when fed with string from an attribute without enforcing
proper NUL termination.
Both bugs can be triggered with malformed netlink message
and don't require any privileges.

The sparc64 kernel's EXPORT_SYMBOL(_mcount) is inside an
#ifdef CONFIG_SMP. This breaks modules in non-SMP kernels
built with stack overflow checking (CONFIG_STACK_DEBUG=y),
as modules_install reports:
WARNING: /lib/modules/2.6.17/kernel/drivers/ide/ide-cd.ko needs unknown symbol _mcount
Trivially fixed by moving EXPORT_SYMBOL(_mcount) outside of
the #ifdef CONFIG_SMP.
