The thing is that 'cscope.el' does not allow setting the command line

It turns out the cscope designers already thought of this. The

moves the "-q" and "-k" options from the 'cmd_cscope' to the
'cmd_cscope-file', echoing them into the top of the files listing.

[PATCH] kbuild: modpost needs to cope with new glibc elf header on sparc

on sparc:
Current assign_irq_vector() will panic if interrupt vectors is running
out. But I think how to handle the case of lack of interrupt vectors
should be handled by the caller of this function. For example, some
PCI devices can raise the interrupt signal via both MSI and I/O
APIC. So even if the driver for these device fails to allocate a
vector for MSI, the driver still has a chance to use I/O APIC based
interrupt. But currently there is no chance for these driver to use
I/O APIC based interrupt because kernel will panic when
assign_irq_vector() fails to allocate interrupt vector.
The following patch changes assign_irq_vector() for ia64 to return
-ENOSPC on error instead of panic (as i386 and x86_64 versions do).

[IPV4]: multicast API "join" issues
This patch corrects a few problems with the IP_ADD_MEMBERSHIP
socket option:
1) The existing code makes an attempt at reference counting joins when
using the ip_mreqn/imr_ifindex interface. Joining the same group
on the same socket is an error, whatever the API. This leads to
unexpected results when mixing ip_mreqn by index with ip_mreqn by
address, ip_mreq, or other API's. For example, ip_mreq followed by
ip_mreqn of the same group will "work" while the same two reversed
will not.
Fixed to always return EADDRINUSE on a duplicate join and
removed the (now unused) reference count in ip_mc_socklist.
2) The group-search list in ip_mc_join_group() is comparing a full
ip_mreqn structure and all of it must match for it to find the
group. This doesn't correctly match a group that was joined with
ip_mreq or ip_mreqn with an address (with or without an index). It
also doesn't match groups that are joined by different addresses on
the same interface. All of these are the same multicast group,
which is identified by group address and interface index.
Fixed the check to correctly match groups so we don't get
duplicate group entries on the ip_mc_socklist.
3) The old code allocates a multicast address before searching for
duplicates requiring it to free in various error cases. This
patch moves the allocate until after the search and
igmp_max_memberships check, so never a need to allocate, then free
an entry.

The sequence number we store in the sequence id is the last one we received
from the client. So on the next operation we'll check that the client gives
us the next higher number.
We increment sequence id's at the last moment, in encode, so that we're sure
of knowing the right error return. (The decision to increment the sequence id
depends on the exact error returned.)
However on the *first* use of a sequence number, if we set the sequence number
to the one received from the client and then let the increment happen on
encode, we'll be left with a sequence number one to high.
For that reason, ENCODE_SEQID_OP_TAIL only increments the sequence id on
*confirmed* stateowners.
This creates a problem for open reclaims, which are confirmed on first use.
Therefore the open reclaim code, as a special exception, *decrements* the
sequence id, cancelling out the undesired increment on encode. But this
prevents the sequence id from ever being incremented in the case where
multiple reclaims are sent with the same openowner. Yuch!
We could add another exception to the open reclaim code, decrementing the
sequence id only if this is the first use of the open owner.
But it's simpler by far to modify the meaning of the op_seqid field: instead
of representing the previous value sent by the client, we take op_seqid, after
encoding, to represent the *next* sequence id that we expect from the client.
This eliminates the need for special-case handling of the first use of a
stateowner.
