1ab54a936d [PATCH] ia64: note requirement for 8250_pnp, now that 8250_acpi is gone
We removed 8250_acpi in 2.6.17.  If we don't have PNPACPI turned on, we
won't find any ACPI serial devices, so mention this requirement in the
troubleshooting part of the documentation.

CONFIG_PNPACPI is already turned on in all the relevant defconfigs.

a51f4a81e7 [PATCH] IPMI: allow user to override the kernel IPMI daemon enable
After the previous patch to disable the kernel IPMI daemon if interrupts
were available, the issue of broken hardware was raised, and a reasonable
request to add an override was mode.  So here it is.

Allow the user to force the kernel ipmi daemon on or off.  This way,
hardware with broken interrupts or users that are not concerned with
performance can turn it on or off to their liking.

2537d36cf5 [PATCH] Add Pekka to CREDITS
Whomever said...

  "When you meet someone now who is writing a compiler or hacking a Unix
   kernel, at least you know they're not just doing it to pick up chicks."

...has obviously never met a _Linux_ kernel hacker.

Anyway, sometimes people confuse my email addresses, which is why I
really should add the proper one to CREDITS ;-).

873ef76bdc [PATCH] restore parport_pc probing on powermac
The last change for partport_pc did fix the common case for all PowerMacs,
but it broke the case for PCI multiport IO cards.  In fact, the config
option CONFIG_PARPORT_PC_SUPERIO=y lead to a hard crash when cups probed
the parport driver.  It enables the winbond and smsc probing.

Remove the PARPORT_BASE check again, parport_pc_find_nonpci_ports() will
take care of it.  All powerpc configs should have
CONFIG_PARPORT_PC_SUPERIO=n, the code did not find anything on the chrp
boards we tested it on.

Tested on a G4/466 with a PCI card:

ffc5089196 [PATCH] Create kallsyms_lookup_size_offset()
Some uses of kallsyms_lookup() do not need to find out the name of a symbol
and its module's name it belongs.  This is specially true in arch specific
code, which needs to unwind the stack to show the back trace during oops
(mips is an example).  In this specific case, we just need to retreive the
function's size and the offset of the active intruction inside it.

Adds a new entry "kallsyms_lookup_size_offset()" This new entry does
exactly the same as kallsyms_lookup() but does not require any buffers to
store any names.

It returns 0 if it fails otherwise 1.

afefdbb28a [PATCH] VFS: Make filldir_t and struct kstat deal in 64-bit inode numbers
These patches make the kernel pass 64-bit inode numbers internally when
communicating to userspace, even on a 32-bit system.  They are required
because some filesystems have intrinsic 64-bit inode numbers: NFS3+ and XFS
for example.  The 64-bit inode numbers are then propagated to userspace
automatically where the arch supports it.

Problems have been seen with userspace (eg: ld.so) using the 64-bit inode
number returned by stat64() or getdents64() to differentiate files, and
failing because the 64-bit inode number space was compressed to 32-bits, and
so overlaps occur.

This patch:

Make filldir_t take a 64-bit inode number and struct kstat carry a 64-bit
inode number so that 64-bit inode numbers can be passed back to userspace.

The stat functions then returns the full 64-bit inode number where
available and where possible.  If it is not possible to represent the inode
number supplied by the filesystem in the field provided by userspace, then
error EOVERFLOW will be issued.

Similarly, the getdents/readdir functions now pass the full 64-bit inode
number to userspace where possible, returning EOVERFLOW instead when a
directory entry is encountered that can't be properly represented.

Note that this means that some inodes will not be stat'able on a 32-bit
system with old libraries where they were before - but it does mean that
there will be no ambiguity over what a 32-bit inode number refers to.

Note similarly that directory scans may be cut short with an error on a
32-bit system with old libraries where the scan would work before for the
same reasons.

It is judged unlikely that this situation will occur because modern glibc
uses 64-bit capable versions of stat and getdents class functions
exclusively, and that older systems are unlikely to encounter
unrepresentable inode numbers anyway.

6e35aabee1 RDMA/cma: Fix device removal race
The race is as follows:

A process : cma_process_remove() calls cma_remove_id_dev(),
	    which sets id state to CMA_DEVICE_REMOVAL and
	    calls wait_event(dev_remove).

B process : cma_req_handler() had incremented dev_remove,
	    and calls cma_acquire_ib_dev() and on failure
	    calls cma_release_remove(), which does a
	    wake_up of cma_process_remove(). Then
	    cma_req_handler() calls rdma_destroy_id();

A Process : cma_remove_id_dev() gets woken and checks the
	    state of id, and since it is still (wrongly)
	    CMA_DEVICE_REMOVAL, it calls notify_user(id)
	    and if that fails, the caller - cma_process_remove()
	    calls rdma_destroy_id(id). Two processes can
	    call rdma_destroy_id(), resulting in one
	    de-referencing kfreed id_priv.

Fix is for process B to set CMA_DESTROYING in cma_req_handler()
so that process A will return instead of doing a rdma_destroy_id().

25ff3780d4 [WATCHDOG] s3c24XX nowayout
If the driver is not configured for `no way out`,
then the open method should not automatically allow
the setting of allow_close to CLOSE_STATE_ALLOW.

The setting of allow_close nullifies the use of
the magic close via the write path. It means that
in the default state, the watchdog will shut-down
even if the magic close has not been issued.

0235497f7a Add prototype for sigset_from_compat()
Duh.  I screwed up editing David Howells patch in commit
3f2e05e90e, and the actual declaration for
the sigset_from_compat() function went missing. My bad.

Olaf Hering saved the day and noticed that I'm a moron.
