serial: 8250: Keep 8250.<xxxx> module options functional after driver rename
With commit
835d844d1 (8250_pnp: do pnp probe before legacy probe), the
8250 driver was renamed to 8250_core. This means any existing usage of
the 8259.<xxxx> module parameters or as a kernel command line switch is
now broken, as the 8250_core driver doesn't parse options belonging to
something called "8250".
To solve this, we redefine the module options in a dummy function using
a redefined MODULE_PARAM_PREFX when built into the kernel. In the case
where we're building as a module, we provide an alias to the old 8250
name. The dummy function prevents compiler errors due to global variable
redefinitions that happen as part of the module_param_ macro expansions.

tty/8250_pnp: serial port detection regression since v3.7
The InsydeH2O BIOS (version dated 09/12/2011) has the following in
its pnp resouces for its serial ports:
$ cat /sys/bus/pnp/devices/00:0b/resources
state = active
io disabled
irq disabled
We do not check if the resources are disabled, and create a bogus
ttyS* device. Since commit

Note, the BIOS can also be upgraded, fixing this problem, but for people
who can't do that, this fix is needed.

http://marc.info/?l=linux-serial&m=

Looking back at that thread there were two issues in the original patch.
1) The I/O ports for the UARTs are within BAR2 not BAR0. This can been seen in the original post.
2) A serial quirk isn't needed as these cards have no memory in BAR0 which makes pci_plx9050_init just return.
This patch fixes the 4 port support to use BAR2, removes the bogus quirk and adds support for the 8 port card.

keys: fix race with concurrent install_user_keyrings()
This fixes CVE-2013-1792.
There is a race in install_user_keyrings() that can cause a NULL pointer
dereference when called concurrently for the same user if the uid and
uid-session keyrings are not yet created. It might be possible for an
unprivileged user to trigger this by calling keyctl() from userspace in
parallel immediately after logging in.
Assume that we have two threads both executing lookup_user_key(), both
looking for KEY_SPEC_USER_SESSION_KEYRING.
THREAD A THREAD B
=============================== ===============================
==>call install_user_keyrings();
if (!cred->user->session_keyring)
==>call install_user_keyrings()
...
user->uid_keyring = uid_keyring;
if (user->uid_keyring)
return 0;
<==
key = cred->user->session_keyring [== NULL]
user->session_keyring = session_keyring;
atomic_inc(&key->usage); [oops]
At the point thread A dereferences cred->user->session_keyring, thread B
hasn't updated user->session_keyring yet, but thread A assumes it is
populated because install_user_keyrings() returned ok.
The race window is really small but can be exploited if, for example,
thread B is interrupted or preempted after initializing uid_keyring, but
before doing setting session_keyring.
This couldn't be reproduced on a stock kernel. However, after placing
systemtap probe on 'user->session_keyring = session_keyring;' that
introduced some delay, the kernel could be crashed reliably.
Fix this by checking both pointers before deciding whether to return.
Alternatively, the test could be done away with entirely as it is checked
inside the mutex - but since the mutex is global, that may not be the best
way.

xen: arm: mandate EABI and use generic atomic operations.
Rob Herring has observed that
c81611c4e96f "xen: event channel arrays are
xen_ulong_t and not unsigned long" introduced a compile failure when building
without CONFIG_AEABI:
/tmp/ccJaIZOW.s: Assembler messages:
/tmp/ccJaIZOW.s:831: Error: even register required -- `ldrexd r5,r6,[r4]'
Will Deacon pointed out that this is because OABI does not require even base
registers for 64-bit values. We can avoid this by simply using the existing
atomic64_xchg operation and the same containerof trick as used by the cmpxchg
macros. However since this code is used on memory which is shared with the
hypervisor we require proper atomic instructions and cannot use the generic
atomic64 callbacks (which are based on spinlocks), therefore add a dependency
on !GENERIC_ATOMIC64. Since we already depend on !CPU_V6 there isn't much
downside to this.
While thinking about this we also observed that OABI has different struct
alignment requirements to EABI, which is a problem for hypercall argument
structs which are shared with the hypervisor and which must be in EABI layout.
Since I don't expect people to want to run OABI kernels on Xen depend on
CONFIG_AEABI explicitly too (although it also happens to be enforced by the
!GENERIC_ATOMIC64 requirement too).

ksm: fix m68k build: only NUMA needs pfn_to_nid
A CONFIG_DISCONTIGMEM=y m68k config gave
mm/ksm.c: In function `get_kpfn_nid':
mm/ksm.c:492: error: implicit declaration of function `pfn_to_nid'
linux/mmzone.h declares it for CONFIG_SPARSEMEM and CONFIG_FLATMEM, but
expects the arch's asm/mmzone.h to declare it for CONFIG_DISCONTIGMEM
(see arch/mips/include/asm/mmzone.h for example).
Or perhaps it is only expected when CONFIG_NUMA=y: too much of a maze,
and m68k got away without it so far, so fix the build in mm/ksm.c.

dmi_scan: fix missing check for _DMI_ signature in smbios_present()
Commit
9f9c9cbb6057 ("drivers/firmware/dmi_scan.c: fetch dmi version
from SMBIOS if it exists") hoisted the check for "_DMI_" into
dmi_scan_machine(), which means that we don't bother to check for
"_DMI_" at offset 16 in an SMBIOS entry. smbios_present() may also call
dmi_present() for an address where we found "_SM_", if it failed further
validation.
Check for "_DMI_" in smbios_present() before calling dmi_present().

Revert parts of "hlist: drop the node parameter from iterators"
Commit
b67bfe0d42ca ("hlist: drop the node parameter from iterators")
did a lot of nice changes but also contains two small hunks that seem to
have slipped in accidentally and have no apparent connection to the
intent of the patch.
This reverts the two extraneous changes.

idr: remove WARN_ON_ONCE() on negative IDs
idr_find(), idr_remove() and idr_replace() used to silently ignore the
sign bit and perform lookup with the rest of the bits. The weird behavior
has been changed such that negative IDs are treated as invalid. As the
behavior change was subtle, WARN_ON_ONCE() was added in the hope of
determining who's calling idr functions with negative IDs so that they can
be examined for problems.
Up until now, all two reported cases are ID number coming directly from
userland and getting fed into idr_find() and the warnings seem to cause
more problems than being helpful. Drop the WARN_ON_ONCE()s.
