The __init directives should go on the definitions of things, not the
declaration, also __init is meaningless for inline functions, so
remove it from prom.h. This allows us to get rid of a useless
#include, but most of the rest of them are useless too, so kill them
as well.
If of_i2c.c needs irq definitions, it should include linux/irq.h
directly, not assume indirect inclusion via asm/prom.h.

This patch refactors the early init parsing of the chosen node so that
architectures aren't forced to provide an empty implementation of
early_init_dt_scan_chosen_arch. Instead, if an architecture wants to
do something different, it can either use a wrapper function around
early_init_dt_scan_chosen(), or it can replace it altogether.
This patch was written in preparation to adding device tree support to
both x86 ad MIPS.

The current code allocates and manages platform_devices created from
the device tree manually. It also uses an unsafe shortcut for
allocating the platform_device and the resource table at the same
time. (which I added in the last rework; sorry).
This patch refactors the code to use platform_device_alloc() for
allocating new devices. This reduces the amount of custom code
implemented by of_platform, eliminates the unsafe alloc trick, and has
the side benefit of letting the platform_bus code manage freeing the
device data and resources when the device is freed.

The REDIRECT target and the older TProxy versions used the primary address
of the incoming interface as the default value of the --on-ip parameter.
This was unintentionally changed during the initial TProxy submission and
caused confusion among users.
Since IPv6 has no notion of primary address, we just select the first address
on the list: this way the socket lookup finds wildcard bound sockets
properly and we cannot really do better without the user telling us the
IPv6 address of the proxy.
This is implemented for both IPv4 and IPv6.

Have unhash_client_locked() remove client and associated sessions from
global hashes, but delay further dismantling till free_client().
(After unhash_client_locked(), the only remaining references outside the
destroying thread are from any connections which have xpt_user callbacks
registered.)
This will simplify locking on session destruction.

Following rfc 5661, section 18.36.4: "If the session is not successfully
created, then no changes are made to any client records on the server."
We shouldn't be confirming or incrementing the sequence id in this case.
Signed-off-by: J. Bruce Fields <bfields@redhat.com>
|

Currently we don't deal well with a client that has multiple sessions
associated with it (even simultaneously, or serially over the lifetime
of the client).
In particular, we don't attempt to keep the backchannel running after
the original session diseappears.
We will fix that soon.
Once we do that, we need the slot sequence number to be per-session;
otherwise, for example, we cannot correctly handle a case like this:
- All session 1 connections are lost.
- The client creates session 2. We use it for the backchannel
(since it's the only working choice).
- The client gives us a new connection to use with session 1.
- The client destroys session 2.
At this point our only choice is to go back to using session 1. When we
do so we must use the sequence number that is next for session 1. We
therefore need to maintain multiple sequence number streams.

The backchannel should be associated with a session, it isn't really
global to the client.
We do, however, want a pointer global to the client which tracks which
session we're currently using for client-based callbacks.
This is a first step in that direction; for now, just reshuffling of
code with no significant change in behavior.

The source address field in the transport's sock_xprt is initialized
ONLY IF the RPC application passed a pointer to a source address
during the call to rpc_create(). However, xs_bind() subsequently uses
the value of this field without regard to whether the source address
was initialized during transport creation or not.
So far we've been lucky: the uninitialized value of this field is
zeroes. xs_bind(), until recently, used only the sin[6]_addr field in
this sockaddr, and all zeroes is a valid value for this: it means
ANYADDR. This is a happy coincidence.
However, xs_bind() now wants to use the sa_family field as well, and
expects it to be initialized to something other than zero.
Therefore, the source address sockaddr field should be fully
initialized at transport create time in _every_ case, not just when
the RPC application wants to use a specific bind address.
Bruce added a workaround for this missing initialization by adjusting
commit 6bc9638a, but the "right" way to do this is to ensure that the
source address sockaddr is always correctly initialized from the
get-go.
This patch doesn't introduce a behavior change. It's simply a
clean-up of Bruce's fix, to prevent future problems of this kind. It
may look like overkill, but
a) it clearly documents the default initial value of this field,
b) it doesn't assume that the sockaddr_storage memory is first
initialized to any particular value, and
c) it will fail verbosely if some unknown address family is passed
in

eeepc-laptop provides a sysfs interface to read and control what it
calls cpufv. When WMI is enabled, the ACPI interface changes slightly
and becames a write-only control with 3 valid values.
Expose cpufv again to allow for user space utils that can extended battery
life noticably and come a little closer to parity with eeepc-laptop.
Write-only is OK for most user space apps because read status was
mostly used to prevent unneeded mode changes. Since this same check
to ignore changes to same mode also exists in the DSDT then it was
wasted ACPI call.
acpi_osi="!Windows 2009" can be used for get back eeepc-laptop's
read support of cpufv for debugging things such as behaviour
during resume.
This patch was tested with EEE PC 1005PE by monitoring powertop output while
writing values of "0", "1", and "2" and by reviewing the decompiled DSDT of
an 1201NL and comparing it to 1005PE's DSDT.

These are mousepad toggle, resolution change, screen off,

Fn-F3, F4, F7, and F9, respectively.
Also, added a new hot key for power toggles (Fn-Space on 1005PE)
and is meant to drive cpufv interface from userspace.

Function acpi_pcc_retrieve_biosdata is always called with parameters
(pcc, pcc->sinf), so we can drop the second parameter. It was
dangerous to pass the sinf array separately anyway, as its length is
checked as pcc->num_sifr, which pretty much assumed it was pcc->sinf
(or at least had the same size.)
This change makes the code slightly more compact and thus marginally
faster.

acpi_pcc_retrieve_biosdata() returns success instead of error if
HKEY.SINF is invalid. Fix this.
Furthermore, if acpi_pcc_retrieve_biosdata() returns an error
during device addition, initialization is properly reverted but value
0 is returned, which means success. This would cause a crash when
later using or removing the device, so fix this too.

After a period of RFC for this driver, I think it is ready
for inclusion in the platform-driver-x86 tree, hopefully to
be staged in the next merge window into Linus's tree.
--Vernon
------------------------------------------------------------
IBM Real-Time "SMI Free" mode driver
This driver supports the Real-Time Linux (RTL) BIOS feature.
The RTL feature allows non-fatal System Management Interrupts
(SMIs) to be disabled on supported IBM platforms and is
intended to be coupled with a user-space daemon to monitor
the hardware in a way that can be prioritized and scheduled
to better suit the requirements for the system.
The Device is presented as a special "_RTL_" table to the OS
in the Extended BIOS Data Area. There is a simple protocol
for entering and exiting the mode at runtime. This driver
creates a simple sysfs interface to allow a simple entry and
exit from RTL mode in the UFI/BIOS.
Since the driver is specific to IBM SystemX hardware (x86-
based servers) it only builds on x86 builds. To reduce the
risk of loading on the wrong hardware, the module uses DMI
information and checks a list of servers that are known to
work.

Add a software rfkill switch for the WLAN interface in the OLPC XO-1
laptop. It uses the OLPC embedded controller to cut/restore power to
the Marvell WLAN chip on the motherboard.

The hdaps driver isn't a hardware monitoring driver, so it shouldn't
live under driver/hwmon. drivers/platform/x86 seems much more
appropriate, as the driver is only useful on x86 laptops.
