compat: backport seq_file's user namespace addition

adb37c4, which as per linux-next may get to
v3.7-rc1, introduced adding a user namespace to a
struct seq_file. For older kernels with CONFIG_USER_NS
support just access the user_name space via the struct
file. For kernels without CONFIG_USER_NS pass the
init_user_ns. There is a special case to handle for
kernels with CONFIG_USER_NS prior to v2.6.38 --
see commit

userns: Make seq_file's user namespace accessible
struct file already has a user namespace associated with it
in file->f_cred->user_ns, unfortunately because struct
seq_file has no struct file backpointer associated with
it, it is difficult to get at the user namespace in seq_file
context. Therefore add a helper function seq_user_ns to return
the associated user namespace and a user_ns field to struct
seq_file to be used in implementing seq_user_ns.

coredump: remove VM_ALWAYSDUMP flag
The motivation for this patchset was that I was looking at a way for a
qemu-kvm process, to exclude the guest memory from its core dump, which
can be quite large. There are already a number of filter flags in
/proc/<pid>/coredump_filter, however, these allow one to specify 'types'
of kernel memory, not specific address ranges (which is needed in this
case).
Since there are no more vma flags available, the first patch eliminates
the need for the 'VM_ALWAYSDUMP' flag. The flag is used internally by
the kernel to mark vdso and vsyscall pages. However, it is simple
enough to check if a vma covers a vdso or vsyscall page without the need
for this flag.
The second patch then replaces the 'VM_ALWAYSDUMP' flag with a new
'VM_NODUMP' flag, which can be set by userspace using new madvise flags:
'MADV_DONTDUMP', and unset via 'MADV_DODUMP'. The core dump filters
continue to work the same as before unless 'MADV_DONTDUMP' is set on the
region.
The qemu code which implements this features is at:
http://people.redhat.com/~jbaron/qemu-dump/qemu-dump.patch
In my testing the qemu core dump shrunk from 383MB -> 13MB with this
patch.
I also believe that the 'MADV_DONTDUMP' flag might be useful for
security sensitive apps, which might want to select which areas are
dumped.
This patch:
The VM_ALWAYSDUMP flag is currently used by the coredump code to
indicate that a vma is part of a vsyscall or vdso section. However, we
can determine if a vma is in one these sections by checking it against
the gate_vma and checking for a non-NULL return value from
arch_vma_name(). Thus, freeing a valuable vma bit.

coredump: add VM_NODUMP, MADV_NODUMP, MADV_CLEAR_NODUMP
Since we no longer need the VM_ALWAYSDUMP flag, let's use the freed bit
for 'VM_NODUMP' flag. The idea is is to add a new madvise() flag:
MADV_DONTDUMP, which can be set by applications to specifically request
memory regions which should not dump core.
The specific application I have in mind is qemu: we can add a flag there
that wouldn't dump all of guest memory when qemu dumps core. This flag
might also be useful for security sensitive apps that want to absolutely
make sure that parts of memory are not dumped. To clear the flag use:
MADV_DODUMP.

userns: Add kuid_t and kgid_t and associated infrastructure in uidgid.h
Start distinguishing between internal kernel uids and gids and
values that userspace can use. This is done by introducing two
new types: kuid_t and kgid_t. These types and their associated
functions are infrastructure are declared in the new header
uidgid.h.
Ultimately there will be a different implementation of the mapping
functions for use with user namespaces. But to keep it simple
we introduce the mapping functions first to separate the meat
from the mechanical code conversions.
Export overflowuid and overflowgid so we can use from_kuid_munged
and from_kgid_munged in modular code.

The uidgid.h header file is provided for older kernels and for
newer kernels we use include_next trick. The only difference
here is that compat-3.5.c now exports overflowuid and
overflowgid in the case that CONFIG_UID16 was not defined
given that on older kernels these were not exported although
linux/highuid.h always has historically provided the extern
declaration for them.
Apart from all this we also force inclusion of uidgid.h
within the compat framework now given that in newer
kernels its expected to be included by many header files
and modules without them having included it in upstream
code already.

PCI: Add accessors for PCI Express Capability
The PCI Express Capability (PCIe spec r3.0, sec 7.8) comes in two
versions, v1 and v2. In v1 Capability structures (PCIe spec r1.0 and
r1.1), some fields are optional, so the structure size depends on the
device type.
This patch adds functions to access this capability so drivers don't
have to be aware of the differences between v1 and v2. Note that these
new functions apply only to the "PCI Express Capability," not to any of
the other "PCI Express Extended Capabilities" (AER, VC, ACS, MFVC, etc.)
Function pcie_capability_read_word/dword() reads the PCIe Capabilities
register and returns the value in the reference parameter "val". If
the PCIe Capabilities register is not implemented on the PCIe device,
"val" is set to 0.
Function pcie_capability_write_word/dword() writes the value to the
specified PCIe Capability register.
Function pcie_capability_clear_and_set_word/dword() sets and/or clears bits
of a PCIe Capability register.

This is not yet upstream into a public release but based on
star alignments I can confidently say this will be part
of the v3.7-rc1 release unless Linus throws a shit fit over
it.
Worth mentioning is that the pci_dev->pcie_flags_reg
is not available on older kernels so we had to write
a pcie_flags_reg() helper. Additionally a lot of pci_reg.h
updates were made into the respective header file as they
were introduced.

etherdevice: introduce eth_broadcast_addr
A lot of code has either the memset or an inefficient copy

$ git describe --contains

v3.4-rc1~3^2~24
This is used by the 3.6-rcX radeon DRM driver (radeon_sa.c) and will
probably be used by other drivers in the near future.
__wake_up_all_locked() is a preprocessor macro around __wake_up_locked()
which gained a 3rd parameter in 3.4.
That's why I backported the new __wake_up_locked() as
compat_wake_up_locked() to avoid name conflicts.
This new function uses the internal __wake_up_common() function
which needed a backport too. I backported it as
compat_wake_up_common() as __wake_up_common() was made available
in kernels between 2.6.28 <= x <= 2.6.30 through wait.h and
dropped after 2.6.30. Renaming fixes build problems of compat
for those kernels.

workqueue: use mod_delayed_work() instead of cancel + queue
Convert delayed_work users doing cancel_delayed_work() followed by
queue_delayed_work() to mod_delayed_work().
Most conversions are straight-forward. Ones worth mentioning are,
* drivers/edac/edac_mc.c: edac_mc_workq_setup() converted to always
use mod_delayed_work() and cancel loop in
edac_mc_reset_delay_period() is dropped.
* drivers/platform/x86/thinkpad_acpi.c: No need to remember whether
watchdog is active or not. @fan_watchdog_active and related code
dropped.
* drivers/power/charger-manager.c: Seemingly a lot of
delayed_work_pending() abuse going on here.
[delayed_]work_pending() are unsynchronized and racy when used like
this. I converted one instance in fullbatt_handler(). Please
conver the rest so that it invokes workqueue APIs for the intended
target state rather than trying to game work item pending state
transitions. e.g. if timer should be modified - call
mod_delayed_work(), canceled - call cancel_delayed_work[_sync]().
* drivers/thermal/thermal_sys.c: thermal_zone_device_set_polling()
simplified. Note that round_jiffies() calls in this function are
meaningless. round_jiffies() work on absolute jiffies not delta
delay used by delayed_work.
v2: Tomi pointed out that __cancel_delayed_work() users can't be
safely converted to mod_delayed_work(). They could be calling it
from irq context and if that happens while delayed_work_timer_fn()
is running, it could deadlock. __cancel_delayed_work() users are
dropped.

compat: fix glibc >= 2.14 requirement
This project uses the vanilla kernels from the Ubuntu

there are a few files which are binary in the kernel

to us here are the ones required to build external modules.
An example:

compat: backport ndo_get_stats64 addition
The net_device_ops data structure gets a new ndo_get_stats64
callback through two patches. For newer kernels that actually do
have the net_device_ops data structure we have no other option
but to #ifdef that code. For older kernels that do not have the
net_device_ops we stuff the new callback into this compat
module / header files and make netdev_attach_ops() ignore it.
And again -- for newer kernels just #ifdef that stuff out.
This is an example of a complex data structure series of
changes through different sets of collateral evolutions.
If we can figure out a way to not requre #ifdef changes
for *newer* kernels that *do* have the net_device_ops it
would be great. One way to likely accomplish this is to
redefine the net_device_ops data structure through a define
for all kernels and make it out own and in our own
netdev_attach_ops() routine handle the differences.
If this would be possible (needs to be proven but I think
Ozan has already proven this) I'm hopeful we'll eventually
be able to replace net_device_ops() collateral evolutions with
0 lines required to be changed on upstream code!
There are two patches that added ndo_get_stats64, fortunately
both were implemented during the 2.6.36 deveopment cycle.

net: Enable 64-bit net device statistics on 32-bit architectures
Use struct rtnl_link_stats64 as the statistics structure.
On 32-bit architectures, insert 32 bits of padding after/before each
field of struct net_device_stats to make its layout compatible with
struct rtnl_link_stats64. Add an anonymous union in net_device; move
stats into the union and add struct rtnl_link_stats64 stats64.
Add net_device_ops::ndo_get_stats64, implementations of which will
return a pointer to struct rtnl_link_stats64. Drivers that implement
this operation must not update the structure asynchronously.
Change dev_get_stats() to call ndo_get_stats64 if available, and to
return a pointer to struct rtnl_link_stats64. Change callers of
dev_get_stats() accordingly.

net: fix 64 bit counters on 32 bit arches
There is a small possibility that a reader gets incorrect values on 32
bit arches. SNMP applications could catch incorrect counters when a
32bit high part is changed by another stats consumer/provider.
One way to solve this is to add a rtnl_link_stats64 param to all
ndo_get_stats64() methods, and also add such a parameter to
dev_get_stats().
Rule is that we are not allowed to use dev->stats64 as a temporary
storage for 64bit stats, but a caller provided area (usually on stack)
Old drivers (only providing get_stats() method) need no changes.

compat: backport u64_stats_sync
This was added as of v2.6.36. This is just a set of static inlines
we we can easily backport this for older kernels. For newer kernels
we just ignore this and include the respective kernel's header.

net: Introduce u64_stats_sync infrastructure
To properly implement 64bits network statistics on 32bit or 64bit hosts,
we provide one new type and four methods, to ease conversions.
Stats producer should use following template granted it already got an
exclusive access to counters (include/linux/u64_stats_sync.h contains
some documentation about details)
u64_stats_update_begin(&stats->syncp);
stats->bytes64 += len;
stats->packets64++;
u64_stats_update_end(&stats->syncp);
While a consumer should use following template to get consistent
snapshot :
u64 tbytes, tpackets;
unsigned int start;
do {
start = u64_stats_fetch_begin(&stats->syncp);
tbytes = stats->bytes64;
tpackets = stats->packets64;
} while (u64_stats_fetch_retry(&stats->lock, syncp));

wl1251: fix oops on early interrupt
commit
f380f2c4a12e913356bd49f8790ec1063c4fe9f8 upstream.
This driver disables interrupt just after requesting it and enables it
later, after interface is up. However currently there is a time window
between request_irq() and disable_irq() where if interrupt arrives, the
driver oopses because it's not yet ready to process it. This can be
reproduced by inserting the module, associating and removing the module
multiple times.
Eliminate this race by setting IRQF_NOAUTOEN flag before request_irq().

raw_spin_unlock_irqrestore() -- but given that the
old version was used in older kernels I see no reasons
why implement this with the new one the new one just
does some typechecking. If someone wants to optimize
this further -- be my guest. The irq_to_desc() call
was also not available on older kernels so we provide
a local translation as I see the desc being accessed

Using NLMSG_GOODSIZE results in multiple pages being used as
nlmsg_new() will automatically add the size of the netlink

Rename leds external interface led_brightness_set() to led_set_brightness().
This is the second phase of the change to reduce confusion between the

now the external interface is led_set_brightness(). The first phase renamed
the internal interface led_set_brightness() to __led_set_brightness().
