[PATCH] ide: reprogram disk pio timings on resume

Add a step to the IDE PM state machine that reprograms disk PIO timings
as the first step on resume. This prevents ide deadlock on
resume-from-ram on my nforce3-based laptop.

An earlier implementation was written entirely within the amd74xx ide
driver, but Alan helpfully pointed out that this is the correct thing to
do globally. Still, I'm only calling hwif->tuneproc() for disks, based
on two things:

 - The existing state machine is already passed over for non-disk drives
 - Previous testing on my laptop shows that the hangs are related only
   to the disk - suspend/resume from a livecd showed that there's no
   need for this on the cdrom.

[PATCH] ide: backport piix fixes from libata into the legacy driver

There are three flags being set by default by the PIIX driver for speeds >
PIO 1, and one not being cleared properly on fallback to PIO0.  The most
important one is the prefetch/post write control which only works for ATA
and can do bad things with ATAPI.

The patch does its best to set the flags correctly for drivers/ide.  Its
not 100% perfect but its closer than the original.  100% perfect requires
proper IORDY handling but this isn't critical (and its not right in libata
either ..  yet)

Sergei Shtylyov <sshtylyov@ru.mvista.com> said:

    BTW, there's quite obvious error here which leads to access outside of
timings[] if somebody passes PIO mode 5 (or autotuning code finds out that
drive supports PIO mode 5). Could have been fixed while at it... Those drives
should be rare, though...

    Actually, there's one more serious issue with piix_tune_drive() -- it
doesn't actually set the drive's own transfer mode.

applies.

1.  The first BUG_ON could trigger when a PREFLUSH IO fails (it would
   fail the original barrier request which hasn't been marked REQ_STARTED
   yet).

2. the rq could have been dequeued already (same as 1).

3.  HWGROUP(drive)->rq could be NULL because of the ide_error() several
   lines earlier.

example, siimage.c does allocate it in both I/O-mapped and custom-mapped
modes).  Remove useless code from the error path of
ide_allocate_dma_engine().

[PATCH] sched: cleanup sched_group cpu_power setup

Up to now sched group's cpu_power for each sched domain is initialized
independently.  This made the setup code ugly as the new sched domains are

Make the sched group cpu_power setup code generic, by using domain child
field and new domain flag in sched_domain.  For most of the sched
domains(except NUMA), sched group's cpu_power is now computed generically
using the domain properties of itself and of the child domain.

sched groups in NUMA domains are setup little differently and hence they
don't use this generic mechanism.

[PATCH] sched: force /sbin/init off isolated cpus

Force /sbin/init off isolated cpus (unless every CPU is specified as an
isolcpu).

Users seem to think that the isolated CPUs shouldn't have much running on
them to begin with.  That's fair enough: intuitive, I guess.  It also means
that the cpu affinity masks of tasks will not include isolcpus by default,
which is also more intuitive, perhaps.

/sbin/init is spawned from the boot CPU's idle thread, and /sbin/init
starts the rest of userspace. So if the boot CPU is specified to be an
isolcpu, then prior to this patch, all of userspace will be run there.

(throw in a couple of plausible devinit -> cpuinit conversions I spotted
while we're here).

[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.

RDMA/cma: Optimize error handling

Reorganize code relating to cma_get_net_info() and rdam_create_id() to
optimize error case handling (no need to alloc memory/etc. as part of
rdma_create_id() if input parameters are wrong).

RDMA/cma: Eliminate unnecessary remove_list

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().

the setting of allow_close to CLOSE_STATE_ALLOW.

Revert Andrew Morton's patch to temporarily hack around the lack of a

be fixed in a different manner.

Also make linux/compat.h #include asm/signal.h to gain a definition of
sigset_t so that it can externally declare sigset_from_compat().

This has been compile-tested for i386, x86_64, ia64, mips, mips64, frv, ppc and
ppc64 and run-tested on frv.

[PATCH] replace cad_pid by a struct pid

There are a few places in the kernel where the init task is signaled.  The
ctrl+alt+del sequence is one them.  It kills a task, usually init, using a
cached pid (cad_pid).

This patch replaces the pid_t by a struct pid to avoid pid wrap around
problem.  The struct pid is initialized at boot time in init() and can be
modified through systctl with

/proc/sys/kernel/cad_pid

[ I haven't found any distro using it ? ]

It also introduces a small helper routine kill_cad_pid() which is used
where it seemed ok to use cad_pid instead of pid 1.

I think this is not safe.  get_pid() can be preempted after checking "pid
!= NULL".  Then the task exits, does detach_pid(), and RCU frees the pid.
