The DRR scheduler requires that items on the active list are work
conserving, i.e. do not hold on to skbs for throttling purposes, etc.
Attaching e.g. tbf renders DRR useless because all other classes on the
active list are delayed as well.
So, warn users that this configuration won't work as expected; we
already do this in couple of other qdiscs, see e.g.
commit b00355db3f88d96810a60011a30cfb2c3469409d
('pkt_sched: sch_hfsc: sch_htb: Add non-work-conserving warning handler')
The 'const' change is needed to avoid compiler warning ("discards 'const'
qualifier from pointer target type").

In skb_checksum complete, if we need to compute the checksum for the
packet (via skb_checksum) save the result as CHECKSUM_COMPLETE.

Also, added csum_complete_sw flag to distinguish between software and

Currently when the first checksum in a packet is validated using
CHECKSUM_COMPLETE, ip_summed is overwritten to be CHECKSUM_UNNECESSARY
so that any subsequent checksums in the packet are not correctly
validated.
This patch adds csum_valid flag in sk_buff and uses that to indicate
validated checksum instead of setting CHECKSUM_UNNECESSARY. The bit
is set accordingly in the skb_checksum_validate_* functions. The flag
is checked in skb_checksum_complete, so that validation is communicated
between checksum_init and checksum_complete sequence in TCP and UDP.

The majority of these changes are cleanups and fixes across all drivers.
Redundant error messages are removed and more PWM controllers set the
.can_sleep flag to signal that they can't be used in atomic context.
Support is added for the Broadcom Kona family of SoCs and the Intel LPSS
driver can now probe PCI devices in addition to ACPI devices. Upon shut-
down, the pwm-backlight driver will now power off the backlight. It also
uses the new descriptor-based GPIO API for more concise GPIO handling.
A large chunk of these changes also converts platforms to use the lookup
mechanism rather than relying on the global number space to reference
PWM devices. This is largely in preparation for more unification and
cleanups in future patches. Eventually it will allow the legacy PWM API
to be removed.

and set the residual length to the unused part of the allocation length.
Add a helper function that command handlers (INQUIRY, READ CAPACITY,

residual for commands that don't use the full initiator allocation in the
handlers for READ CAPACITY, READ CAPACITY(16), INQUIRY, MODE SENSE and
REPORT LUNS.

The macro 'A' used in internal BPF interpreter:
#define A regs[insn->a_reg]
was easily confused with the name of classic BPF register 'A', since
'A' would mean two different things depending on context.
This patch is trying to clean up the naming and clarify its usage in the
following way:
- A and X are names of two classic BPF registers
- BPF_REG_A denotes internal BPF register R0 used to map classic register A
in internal BPF programs generated from classic
- BPF_REG_X denotes internal BPF register R7 used to map classic register X
in internal BPF programs generated from classic
- internal BPF instruction format:
struct sock_filter_int {
__u8 code; /* opcode */
__u8 dst_reg:4; /* dest register */
__u8 src_reg:4; /* source register */
__s16 off; /* signed offset */
__s32 imm; /* signed immediate constant */
};
- BPF_X/BPF_K is 1 bit used to encode source operand of instruction
In classic:
BPF_X - means use register X as source operand
BPF_K - means use 32-bit immediate as source operand
In internal:
BPF_X - means use 'src_reg' register as source operand
BPF_K - means use 32-bit immediate as source operand

Adds two trace events which supply the same info that initcall_debug
provides, but via ftrace instead of dmesg. The existing initcall_debug
calls require the pm_print_times_enabled var to be set (either via
sysfs or via the kernel cmd line). The new trace events provide all the
same info as the initcall_debug prints but with less overhead, and also
with coverage of device prepare and complete device callbacks.
These events replace the device_pm_report_time event (which has been
removed). device_pm_callback_start is called first and provides the device
and callback info. device_pm_callback_end is called after with the
device name and error info. The time and pid are gathered from the trace
data headers.

The kernel has no concept of capabilities with respect to inodes; inodes
exist independently of namespaces. For example, inode_capable(inode,
CAP_LINUX_IMMUTABLE) would be nonsense.
This patch changes inode_capable to check for uid and gid mappings and
renames it to capable_wrt_inode_uidgid, which should make it more
obvious what it does.

"The largest piece is a long-overdue rewrite of the xdr code to remove
some annoying limitations: for example, there was no way to return
ACLs larger than 4K, and readdir results were returned only in 4k
chunks, limiting performance on large directories.
Also:
- part of Neil Brown's work to make NFS work reliably over the
loopback interface (so client and server can run on the same
machine without deadlocks). The rest of it is coming through
other trees.
- cleanup and bugfixes for some of the server RDMA code, from

This patch adds iWARP Port Mapper (IWPM) Version 2 support. The iWARP
Port Mapper implementation is based on the port mapper specification
section in the Sockets Direct Protocol paper -
http://www.rdmaconsortium.org/home/draft-pinkerton-iwarp-sdp-v1.0.pdf
Existing iWARP RDMA providers use the same IP address as the native
TCP/IP stack when creating RDMA connections. They need a mechanism to
claim the TCP ports used for RDMA connections to prevent TCP port
collisions when other host applications use TCP ports. The iWARP Port
Mapper provides a standard mechanism to accomplish this. Without this
service it is possible for RDMA application to bind/listen on the same
port which is already being used by native TCP host application. If
that happens the incoming TCP connection data can be passed to the
RDMA stack with error.
The iWARP Port Mapper solution doesn't contain any changes to the
existing network stack in the kernel space. All the changes are
contained with the infiniband tree and also in user space.
The iWARP Port Mapper service is implemented as a user space daemon
process. Source for the IWPM service is located at
http://git.openfabrics.org/git?p=~tnikolova/libiwpm-1.0.0/.git;a=summary
The iWARP driver (port mapper client) sends to the IWPM service the
local IP address and TCP port it has received from the RDMA
application, when starting a connection. The IWPM service performs a
socket bind from user space to get an available TCP port, called a
mapped port, and communicates it back to the client. In that sense,
the IWPM service is used to map the TCP port, which the RDMA
application uses to any port available from the host TCP port
space. The mapped ports are used in iWARP RDMA connections to avoid
collisions with native TCP stack which is aware that these ports are
taken. When an RDMA connection using a mapped port is terminated, the
client notifies the IWPM service, which then releases the TCP port.
The message exchange between the IWPM service and the iWARP drivers
(between user space and kernel space) is implemented using netlink
sockets.
1) Netlink interface functions are added: ibnl_unicast() and
ibnl_mulitcast() for sending netlink messages to user space
2) The signature of the existing ibnl_put_msg() is changed to be more
generic
3) Two netlink clients are added: RDMA_NL_NES, RDMA_NL_C4IW
corresponding to the two iWarp drivers - nes and cxgb4 which use
the IWPM service
4) Enums are added to enumerate the attributes in the netlink
messages, which are exchanged between the user space IWPM service
and the iWARP drivers

The per_cpu buffers are created one per possible CPU. But these do
not mean that those CPUs are online, nor do they even exist.
With the addition of the ring buffer polling, it assumes that the
caller polls on an existing buffer. But this is not the case if
the user reads trace_pipe from a CPU that does not exist, and this
causes the kernel to crash.
Simple fix is to check the cpu against buffer bitmask against to see
if the buffer was allocated or not and return -ENODEV if it is
not.
More updates were done to pass the -ENODEV back up to userspace.
