Dean Nelson b7f7b07479 sgi-xp: only build for ia64-sn2 when CONFIG_IA64_GENERIC specified
For the time being build for ia64-sn2 alone when CONFIG_IA64_GENERIC is
specified.

This eliminates a dependency of the XP/XPC drivers on having the GRU
driver insmod'd in order to insmod them, when running on an ia64-sn2
system.

On such a system the GRU driver serves no useful purpose.

Sukadev Bhattiprolu d25141a818 'kill sig -1' must only apply to caller's namespace
Currently "kill <sig> -1" kills processes in all namespaces and breaks the
isolation of namespaces.  Earlier attempt to fix this was discussed at:

	http://lkml.org/lkml/2008/7/23/148

As suggested by Oleg Nesterov in that thread, use "task_pid_vnr() > 1"
check since task_pid_vnr() returns 0 if process is outside the caller's
namespace.

Eric Sandeen 87b811c3f9 ecryptfs: fix memory corruption when storing crypto info in xattrs
When ecryptfs allocates space to write crypto headers into, before copying
it out to file headers or to xattrs, it looks at the value of
crypt_stat->num_header_bytes_at_front to determine how much space it
needs.  This is also used as the file offset to the actual encrypted data,
so for xattr-stored crypto info, the value was zero.

So, we kzalloc'd 0 bytes, and then ran off to write to that memory.
(Which returned as ZERO_SIZE_PTR, so we explode quickly).

The right answer is to always allocate a page to write into; the current
code won't ever write more than that (this is enforced by the
(PAGE_CACHE_SIZE - offset) length in the call to
ecryptfs_generate_key_packet_set).  To be explicit about this, we now send
in a "max" parameter, rather than magically using PAGE_CACHE_SIZE there.

Also, since the pointer we pass down the callchain eventually gets the
virt_to_page() treatment, we should be using a alloc_page variant, not
kzalloc (see also 7fcba05437)

Paul Mundt ce05fcc30e kernel/profile: fix profile_init() section mismatch
profile_init() calls in to alloc_bootmem() on early initialization.  While
alloc_bootmem() is __init, the reference itself is safe in that it is
tucked below a !slab_is_available() check.  So, flag profile_init() as
__ref.

Kurt Garloff 0833422274 mm: increase the default mlock limit from 32k to 64k
By default, non-privileged tasks can only mlock() a small amount of
memory to avoid a DoS attack by ordinary users.  The Linux kernel
defaulted to 32k (on a 4k page size system) to accommodate the needs of
gpg.

However, newer gpg2 needs 64k in various circumstances and otherwise
fails miserably, see bnc#329675.

Change the default to 64k, and make it more agnostic to PAGE_SIZE.

another place of code to be changed when adding a new processor type

Fixed by moving the setting of the CPU type string into the core of the
probing code and a few BUG_ON() test to ensure the CPU probing code indeed
did its job and removing multiple now redundant tests.

Ralf Baechle ba3049ed40 MIPS: Switch FPU emulator trap to BREAK instruction.
Arguably using the address error handler has always been ugly.  But with
processors that handle unaligned loads and stores in hardware the
current mechanism ceases to work so switch it to a BREAK instruction and
allocate break code 514 to the FPU emulator.

Yoichi Yuasa provided a build fix for CONFIG_BUG=n.

Ralf Baechle 076c6e4f4d MIPS: SMP: Do not initialize __cpu_number_map/__cpu_logical_map for CPU 0.
A system isn't necessarily booted on physical processor 0 as this code
assumes.  Also the array happens to be allocated in .bss so it's zero
initialized anyway.  Systems which need to override this can do so in
their mp_ops->smp_setup() method.

David Daney 566f74f6b2 MIPS: Consider value of c0_ebase when computing value of exception base.
It just so happens to be zero on all currently supported systems so this
hasn't bitten yet ...

de-ifdef'ed trap_init() implementation by me.]

Uwe Kleine-König 9c6568501c [ARM] gpio_free might sleep, arm architecture
According to the documentation gpio_free should only be called from task
context only.  To make this more explicit add a might sleep to all
implementations.

This patch changes the gpio_free implementations for the arm architecture.
 DaVinci is skipped on purpose to simplify the merge process for patches
switching it over to use gpiolib as per request by David Brownell.
