the lock is already held when ipic_set_irq_type is called.

I'm also not convinced that ipic_set_irq_type should be changing the
handler at all.  There seem to be several controllers that don't and
several that do.  Those that do would break what appears to be a common
usage of calling set_irq_chip_and_handler followed by set_irq_type, if a
non-standard handler were to be used.  OTOH, irq_create_of_mapping()
doesn't set the handler, but only calls set_irq_type().

[POWERPC] Support feature fixups in vdso's

This patch reworks the feature fixup mecanism so vdso's can be fixed up.
The main issue was that the construct:

        .long   label  (or .llong on 64 bits)

will not work in the case of a shared library like the vdso. It will
generate an empty placeholder in the fixup table along with a reloc,
which is not something we can deal with in the vdso.

The idea here (thanks Alan Modra !) is to instead use something like:

1:
        .long   label - 1b

That is, the feature fixup tables no longer contain addresses of bits of
code to patch, but offsets of such code from the fixup table entry
itself. That is properly resolved by ld when building the .so's. I've
modified the fixup mecanism generically to use that method for the rest
of the kernel as well.

Another trick is that the 32 bits vDSO included in the 64 bits kernel
need to have a table in the 64 bits format. However, gas does not
support 32 bits code with a statement of the form:

        .llong  label - 1b  (Or even just .llong label)

That is, it cannot emit the right fixup/relocation for the linker to use
to assign a 32 bits address to an .llong field. Thus, in the specific
case of the 32 bits vdso built as part of the 64 bits kernel, we are
using a modified macro that generates:

        .long   0xffffffff
        .llong  label - 1b

Note that is assumes that the value is negative which is enforced by
the .lds (those offsets are always negative as the .text is always
before the fixup table and gas doesn't support emiting the reloc the
other way around).

[PATCH] Remove __must_check for device_for_each_child()

Eliminate more __must_check madness.

The return code from device_for_each_child() depends on the values
which the helper function returns.  If the helper function always
returns zero, it's utterly pointless to check the return code from
device_for_each_child().

The only code which knows if the return value should be checked is
the caller itself, so forcing the return code to always be checked
is silly.  Hence, remove the __must_check annotation.

[POWERPC] Simplify stolen time calculation

In calculating stolen time, we were trying to actually account for time
spent in the hypervisor.  We don't really have enough information to do
that accurately, so don't try.  Instead, we now calculate stolen time as
time that the current cpu thread is not actually dispatching instructions.
On chips without a PURR, we cannot do this, so stolen time will always
be zero.  On chips with a PURR, this is merely the difference between
the elapsed PURR values and the elapsed TB values.

This gives us much more sane vaules from tools such as mpstat, even if
they are still a bit strange e.g. 2 busy threads on one cpu will both
appear to have 50% user time and 50% stolen time while 1 busy thread on
a cpu will look like 100% user on one of them and 100% idle on the other.

Gerrit Renker [Wed, 11 Oct 2006 15:26:54 +0000 (16:26 +0100)]
[DCCP]: Fix Oops in DCCPv6

I think I got the cause for the Oops observed in
http://www.mail-archive.com/dccp@vger.kernel.org/msg00578.html

The problem is always with applications listening on PF_INET6 sockets. Apart
from the mentioned oops, I observed another one one, triggered at irregular
intervals via timer interrupt:

    run_timer_softirq -> dccp_keepalive_timer
                      -> inet_csk_reqsk_queue_prune
                      -> reqsk_free
                      -> dccp_v6_reqsk_destructor

The latter function is the problem and is also the last function to be called
in said kernel panic.

In any case, there is a real problem with allocating the right request_sock
which is what this patch tackles.

It fixes the following problem:
 - application listens on PF_INET6
 - DCCPv4 packet comes in, is handed over to dccp_v4_do_rcv, from there
   to dccp_v4_conn_request

Now: socket is PF_INET6, packet is IPv4. The following code then furnishes the
connection with IPv6 - request_sock operations:

   req = reqsk_alloc(sk->sk_prot->rsk_prot);

The first problem is that all further incoming packets will get a Reset since
the connection can not be looked up.

The second problem is worse:
 --> reqsk_alloc is called instead of inet6_reqsk_alloc
 --> consequently inet6_rsk_offset is never set (dangling pointer)
 --> the request_sock_ops are nevertheless still dccp6_request_ops
 --> destructor is called via reqsk_free
 --> dccp_v6_reqsk_destructor tries to free random memory location (inet6_rsk_offset not set)
 --> panic

I have tested this for a while, DCCP sockets are now handled correctly in all
three scenarios (v4/v6 only/v4-mapped).

Commiter note: I've added the dccp_request_sock_ops forward declaration to keep
               the tree building and to reduce the size of the patch for 2.6.19,
               later I'll move the functions to the top of the affected source
               code to match what we have in the TCP counterpart, where this
               problem hasn't existed in the first place, dumb me not to have
               done the same thing on DCCP land 8)

[PATCH] ibmveth: Fix index increment calculation

The recent commit 751ae21c6cd1493e3d0a4935b08fb298b9d89773 introduced a bug
in the producer/consumer index calculation in the ibmveth driver -
incautious use of the post-increment ++ operator resulted in an increment
being immediately reverted.  This patch corrects the logic.

Without this patch, the driver oopses almost immediately after activation
on at least some machines.

[PATCH] drivers/ide/pci/generic.c: re-add the __setup("all-generic-ide",...)

The change from __setup() to module_param_named() requires users to prefix
the option with "generic.".

This patch re-adds the __setup() additionally to the module_param_named().

Usually it would make sense getting rid of such an obsolete __setup() at
some time, but considering that drivers/ide/ is slowly approaching a RIP
status it's already implicitely scheduled for removal.

This patch fixes kernel Bugzilla #7353.
