When isolating for migration, migration starts at the start of a zone
which is not necessarily pageblock aligned. Further, it stops isolating
when COMPACT_CLUSTER_MAX pages are isolated so migrate_pfn is generally
not aligned. This allows isolate_migratepages() to call pfn_to_page() on
an invalid PFN which can result in a crash. This was originally reported
against a 3.0-based kernel with the following trace in a crash dump.

It was also reported by Herbert van den Bergh against 3.1-based kernel
with the following snippet from the console log.
BUG: unable to handle kernel paging request at 01c00008
IP: [<c0522399>] isolate_migratepages+0x119/0x390
*pdpt = 000000002f7ce001 *pde = 0000000000000000
It is expected that it also affects 3.2.x and current mainline.
The problem is that pfn_valid is only called on the first PFN being
checked and that PFN is not necessarily aligned. Lets say we have a case
like this
H = MAX_ORDER_NR_PAGES boundary
| = pageblock boundary
m = cc->migrate_pfn
f = cc->free_pfn
o = memory hole
H------|------H------|----m-Hoooooo|ooooooH-f----|------H
The migrate_pfn is just below a memory hole and the free scanner is beyond
the hole. When isolate_migratepages started, it scans from migrate_pfn to
migrate_pfn+pageblock_nr_pages which is now in a memory hole. It checks
pfn_valid() on the first PFN but then scans into the hole where there are
not necessarily valid struct pages.
This patch ensures that isolate_migratepages calls pfn_valid when
necessary.

Herbert Poetzl reported a performance regression since 2.6.39. The test
is a simple dd read, but with big block size. The reason is:
T1: ra (A, A+128k), (A+128k, A+256k)
T2: lock_page for page A, submit the 256k
T3: hit page A+128K, ra (A+256k, A+384). the range isn't submitted
because of plug and there isn't any lock_page till we hit page A+256k
because all pages from A to A+256k is in memory
T4: hit page A+256k, ra (A+384, A+ 512). Because of plug, the range isn't
submitted again.
T5: lock_page A+256k, so (A+256k, A+512k) will be submitted. The task is
waitting for (A+256k, A+512k) finish.
There is no request to disk in T3 and T4, so readahead pipeline breaks.
We really don't need block plug for generic_file_aio_read() for buffered
I/O. The readahead already has plug and has fine grained control when I/O
should be submitted. Deleting plug for buffered I/O fixes the regression.
One side effect is plug makes the request size 256k, the size is 128k
without it. This is because default ra size is 128k and not a reason we
need plug here.
Vivek said:
: We submit some readahead IO to device request queue but because of nested
: plug, queue never gets unplugged. When read logic reaches a page which is
: not in page cache, it waits for page to be read from the disk
: (lock_page_killable()) and that time we flush the plug list.
:
: So effectively read ahead logic is kind of broken in parts because of
: nested plugging. Removing top level plug (generic_file_aio_read()) for
: buffered reads, will allow unplugging queue earlier for readahead.

In function pre_handler_kretprobe(), the allocated kretprobe_instance
object will get leaked if the entry_handler callback returns non-zero.
This may cause all the preallocated kretprobe_instance objects exhausted.
This issue can be reproduced by changing
samples/kprobes/kretprobe_example.c to probe "mutex_unlock". And the fix
is straightforward: just put the allocated kretprobe_instance object back
onto the free_instances list.

KDFONTOP(GET) currently fails with EIO when being run in a 32bit userland
with a 64bit kernel if the font width is not 8.
This is because of the setting of the KD_FONT_FLAG_OLD flag, which makes
con_font_get return EIO in such case.
This flag should *not* be set for KDFONTOP, since it's actually the whole
point of this flag (see comment in con_font_set for instance).

Fix a race condition that shows in conjunction with xip_file_fault() when
two threads of the same user process fault on the same memory page.
In this case, the race winner will install the page table entry and the
unlucky loser will cause an oops: xip_file_fault calls vm_insert_pfn (via
vm_insert_mixed) which drops out at this check:
retval = -EBUSY;
if (!pte_none(*pte))
goto out_unlock;
The resulting -EBUSY return value will trigger a BUG_ON() in
xip_file_fault.
This fix simply considers the fault as fixed in this case, because the
race winner has successfully installed the pte.

Do not reconfigure the PLL in case it has been configured already
with the requested parameters.
In case of different PLL configuration do only the needed changes.
This can save considerable amount of time since we can avoid the
defined protocol (with delays) for the PLL configuration.

__kuser_cmpxchg64 has a return path using bx lr to get back to the caller.
This is actually ok since the code in question is predicated on
CONFIG_CPU_32v6K, but for the sake of consistency using the usr_ret
macro is probably better.

The recent changes in Realtek auto-parser added the new "Bass Speaker"
and "CLFE" mixer elements which should be tracked as vmaster slaves,
too.

The usb/ch9.h will be installed to /usr/include/linux,
and be used from user space.
But le16_to_cpu() is only defined for kernel code.
Without this patch, user space compile will be broken.

KDFONTOP(GET) currently fails with EIO when being run in a 32bit userland
with a 64bit kernel if the font width is not 8.
This is because the compatibility layer introduced by e9216651 ("tty:
handle VT specific compat ioctls in vt driver") forces the addition of the
KD_FONT_FLAG_OLD flag, which makes con_font_get return EIO in such case.
This flag should *not* be set for KDFONTOP, since it's actually the whole
point of this flag (see comment in con_font_set for instance).

The code looks like:
if (tty->driver->subtype == PTY_TYPE_MASTER) {
...
if (tty->driver == ptm_driver)
But the second if is superfluous because only the ptm_driver is of
PTY_TYPE_MASTER subtype.
Also we can remove the #if now because devpts_pty_kill is defined as
an empty function for non-CONFIG_UNIX98_PTYS configs.
