Make the handling of the hugetlb-backed shm file's name counter SMP-safe.

(What stops hugetlb_zero_setup() racing with umount?)

From: "Kenneth Chen" <kenneth.w.chen@intel.com>

Even though there is a CONFIG_MAX_RAW_DEVS option, it doesn't actually
increase the number of raw devices beyond 256 because during the char
registration, it uses the standard register_chrdev() interface which has
hard coded 256 minor in it.  Here is a patch that fix this problem by using
register_chrdev_region() and cdev_(init/add/del) functions.

From: Andy Whitcroft <andyw@uk.ibm.com>

The vsyscall implementation for ia32 provides two different vsyscall pages;
one to use int80 and the other to use sysenter.  Each includes a common
signal trailer.  The kernel requires the alignment of routines in this
trailer be consistent in both copies.  However this is not enforced at
compile time.  Failure to maintain this alignment typically leads to an
obscure SIGSEGV in init during boot.  This critical alignment requirement
is not well documented.

Below is a patch to better document the alignment requirements and to
enforce the requirement.

tape driver fixes:
 - Link from ccw device to class device in sysfs.
 - Cosmetic changes.
 - Add copyright statements.

From: Martin Schwidefsky <schwidefsky@de.ibm.com>

Fix for z/VM monitor stream:
 - Add try_module_get and module_put to the [un]register functions.
 - Some code beautification.

From: Martin Schwidefsky <schwidefsky@de.ibm.com>

dasd driver fixes:
 - Remove additional dasd attributes for a ccw-device if the discipline
   (=driver) gets unloaded.
 - Fix race of dasd_generic_offline against dasd_open.
 - Remove irq_exit calls from diag interrupt handler. The irq_enter/
   irq_exit is done in the external interrupt handler.

network driver fixes:
 - Use SET_NETDEV_DEV to create the link from the network device to the
   physical device. Remove link from physical to network device.
 - Remove some unnecessary casts in netiucv.
 - Add missing strings to dev_stat_names & dev_event_names.
 - Add missing preempt_disable/preempt_enable pairs in iucv.
 - Allow to change the peer username in netiucv.

Common i/o layer fixes:
 - Improve blacklist argument parsing.
 - Fix device recognition for devices where SenseID fails.
 - Don't try to set a device online that has no driver.
 - Chain a release ccw to the unconditional reserve ccw for forced online.
 - Fix irb accumulation for pure status pending with eswf set.
 - Fix rc handling in qdio_shutdown.
 - Improve retry behavious for busy conditions on qdio.
 - Fix activity check in ccw_device_start/read_dev_chars and read_conf_data.

s390 core changes:
 - Merge 31 and 64 bit NR_CPUS config option. Default to 32 cpus.
 - Remove unused system calls from compat_linux.c.
 - Add statfs64 and fstatfs64. Reserve system call number for
   remap_file_pages.
 - Merge do_signal32 into do_signal.
 - Don't remove the per bit and the program mask from the user psw
   due to a signal.
 - Fix a problem with gdb and interrupted system calls.
 - Fix single stepping of interrupted system calls.
 - Fix compiler warnings in bitops.h.

bitops.c was a bit of a mess wrt formatting so run it through Lindent.  No

When I converted the use of PCI_DMA_foo constants to DMA_foo constants, I
forgot that it's PCI_DMA_FROMDEVICE and DMA_FROM_DEVICE.  The following
fixes that.

From: Tom Rini <trini@kernel.crashing.org>

include/asm-ppc/dma-mapping.h was made to be a 'real' header recently and
therefore missed out on the updates that davem did to all of the other
versions.  This updates <asm-ppc/dma-mapping.h> to match what's expected
now.

From: Tom Rini <trini@kernel.crashing.org>

When Dave Miller updated <asm-ppc/pci.h> for the _for_device and _for_cpu
portions of the PCI DMA API, he assumed that on PPC32 consistent_sync*
would also need to be changed for device or cpu.  This is not the case, so
what this does is the pci_*_for_{cpu,device} calls call
consistent_sync{,page} again.

Fix a cut & paste error in forward porting from 2.4, we don't reference

Fix memory corruption in the HT init on x86-64 recently introduced by me.

Fix from from Suresh B. Siddha.

 - Chen Yang's fix to work with NGROUPS
 - Chen Yang's fix to handle file deletion
 - Remove TCGETS handling and return  -ENOTTY for unknown ioctl code.
 - Removed InterMezzo from BROKEN state

The proc_rtas_init call in procfs was removed (replaced with an
initcall) but the prototype was still hiding. Kill it.

Tested on Epox 8K9A3+ and 4PCA3+ by Tomi Orava <Tomi.Orava@ncircle.nullnet.fi>.

It was tested by a few people and has been in -mm since 2.6.4-rc2-mm1.

ATAPI multi-lun support has been broken for a long time.

It used to be that "(drive->id->last_id & 0x7) + 1" was used as
shost->max_lun and the "hdXlun=" kernel parameter could be used to
override this value.

However it was far from optimal:
- people played with "hdXlun=" and then complained about multiple instances
  of the same device (most ATAPI drives respond to each LUN)
- probably some devices return 7 not 0 in id->last_id (=> 7 x same device)

This patch from Willem Riede <wrlk@riede.org> fixes it w/o need
for "hdXlun=" option.  It was tested by Willem on ATAPI PD/CD drive.

wait_task_inactive is now only used in two non-time-critical places: the
ptrace code to guarantee a schedule and kthread_bind so we can change
the thread CPU.  Unfortunately with preempt, the code as stands has a
race: we might return because the thread is preempted, not because it
actually reached schedule().  The ptrace code (probably) doesn't care,
but the kthread code does.

This patch simplifies the (now over-optimized) code, and does a yield()
for the preemption case.

RX skbs are always considered maximally sized, until actual reception
of the RX frame occurs.  So, update this driver to always map and
unmap a maximally sized skb.  This fixes this driver on several
non-x86 platforms.
