Linus Torvalds 7f81890687 x86: don't use 'access_ok()' as a range check in get_user_pages_fast()
It's really not right to use 'access_ok()', since that is meant for the
normal "get_user()" and "copy_from/to_user()" accesses, which are done
through the TLB, rather than through the page tables.

Why? access_ok() does both too few, and too many checks.  Too many,
because it is meant for regular kernel accesses that will not honor the
'user' bit in the page tables, and because it honors the USER_DS vs
KERNEL_DS distinction that we shouldn't care about in GUP.  And too few,
because it doesn't do the 'canonical' check on the address on x86-64,
since the TLB will do that for us.

So instead of using a function that isn't meant for this, and does
something else and much more complicated, just do the real rules: we
don't want the range to overflow, and on x86-64, we want it to be a
canonical low address (on 32-bit, all addresses are canonical).

Rainer Weikusat 39c58f37a1 ide-cd: prevent null pointer deref via cdrom_newpc_intr
With 2.6.30, the error handling code in cdrom_newpc_intr was changed
to deal with partial request failures by normally completing the 'good'
parts of a request and only 'error' the last (and presumably,
incompletely transferred) bio associated with a particular
request. In order to do this, ide_complete_rq is called over
ide_cd_error_cmd() to partially complete the rq. The block layer
does partial completion only for requests with bio's and if the
rq doesn't have one (eg 'GPCMD_READ_DISC_INFO') the request is
completed as a whole and the drive->hwif->rq pointer set to NULL
afterwards. When calling ide_complete_rq again to report
the error, this null pointer is derefenced, resulting in a kernel
crash.

This fixes http://bugzilla.kernel.org/show_bug.cgi?id=13399.

Frederic Weisbecker c85a17e226 tracing/urgent: fix unbalanced ftrace_start_up
Perfcounter reports the following stats for a wide system
profiling:

 #
 # (2364 samples)
 #
 # Overhead  Symbol
 # ........  ......
 #
    15.40%  [k] mwait_idle_with_hints
     8.29%  [k] read_hpet
     5.75%  [k] ftrace_caller
     3.60%  [k] ftrace_call
     [...]

This snapshot has been taken while neither the function tracer nor
the function graph tracer was running.
With dynamic ftrace, such results show a wrong ftrace behaviour
because all calls to ftrace_caller or ftrace_graph_caller (the patched
calls to mcount) are supposed to be patched into nop if none of those
tracers are running.

The problem occurs after the first run of the function tracer. Once we
launch it a second time, the callsites will never be nopped back,
unless you set custom filters.
For example it happens during the self tests at boot time.
The function tracer selftest runs, and then the dynamic tracing is
tested too. After that, the callsites are left un-nopped.

This is because the reset callback of the function tracer tries to
unregister two ftrace callbacks in once: the common function tracer
and the function tracer with stack backtrace, regardless of which
one is currently in use.
It then creates an unbalance on ftrace_start_up value which is expected
to be zero when the last ftrace callback is unregistered. When it
reaches zero, the FTRACE_DISABLE_CALLS is set on the next ftrace
command, triggering the patching into nop. But since it becomes
unbalanced, ie becomes lower than zero, if the kernel functions
are patched again (as in every further function tracer runs), they
won't ever be nopped back.

Note that ftrace_call and ftrace_graph_call are still patched back
to ftrace_stub in the off case, but not the callers of ftrace_call
and ftrace_graph_caller. It means that the tracing is well deactivated
but we waste a useless call into every kernel function.

This patch just unregisters the right ftrace_ops for the function
tracer on its reset callback and ignores the other one which is
not registered, fixing the unbalance. The problem also happens
is .30

Krzysztof Helt 4b19828968 fbdev: do not allow VESA modes without compiled-in drivers
Do not accept VESA modes by the "vga=" kernel parameter if there is no
frame buffer driver compiled-in to handle it.

Also, there is a comment added to the Kconfig description after Werner
Lemberg's suggestion

FUJITA Tomonori dbe6f18691 dma-mapping: mark dma_sync_single and dma_sync_sg as deprecated
dma_sync_single() and dma_sync_sg() have been described as "Backwards
compat, remove in 2.7.x" for a long time (since 2.6.5).

This marks dma_sync_single() and dma_sync_sg() as deprecated so the users
get notified before removing them.

We're about to make DMA_nnBIT_MASK() emit `deprecated' warnings.  Convert the
remaining stragglers which are visible to the x86_64 build.

Dirk Eibach a90b037583 char: moxa, prevent opening unavailable ports
In moxa.c there are 32 minor numbers reserved for each device.  The number
of ports actually available per device is stored in
moxa_board_conf->numPorts.  This number is not considered in moxa_open().
Opening a port that is not available results in a kernel oops.  This patch
adds a test to moxa_open() that prevents opening unavailable ports.

Mike Frysinger 0b9ce5a201 istallion: add missing __devexit marking
The remove member of the pci_driver stli_pcidriver uses __devexit_p(), so
the remove function itself should be marked with __devexit.  Even more so
considering the probe function is marked with __devinit.

Oleg Nesterov befca96779 ptrace: wait_task_zombie: do not account traced sub-threads
The bug is ancient.

If we trace the sub-thread of our natural child and this sub-thread exits,
we update parent->signal->cxxx fields.  But we should not do this until
the whole thread-group exits, otherwise we account this thread (and all
other live threads) twice.

Add the task_detached() check.  No need to check thread_group_empty(),
wait_consider_task()->delay_group_leader() already did this.

Atsushi Nemoto e6229bec25 rtc: make rtc_update_irq callable with irqs enabled
The rtc_update_irq() might be called with irqs enabled, if a interrupt
handler was registered without IRQF_DISABLED.  Use
spin_lock_irqsave/spin_unlock_irqrestore instead of spin_lock/spin_unlock.

Also update kerneldoc and drivers which do extra work to follow the
current interface spec, as suggestted by David Brownell.

Anton Vorontsov 575c5807f6 spi_mpc8xxx: s/83xx/8xxx/g
Since we renamed the file, we might want to rename the file internals too.

Though we don't bother with changing platform driver name and platform
module alias.  The stuff is legacy and hopefully we'll remove it soon.

Anton Vorontsov b9b9af11fe spi_mpc83xx: split mpc83xx_spi_work() into two routines
mpc83xx_spi_work() is quite large, with up to five indentation levels and
is quite difficult to read.

So, split the function in two parts:
1. mpc83xx_spi_work() now only traverse queued spi messages;
2. mpc83xx_spi_do_one_msg() only manages single messages.

There should be no functional changes.
