As usual, the reason of this breakage is quite silly: in do_entIF, we
are checking for PS == 0 to see whether it was a kernel BUG() or
userspace trap.It works, unless BUG() happens in interrupt - PS is not 0 in kernel mode
due to non-zero IPL, and the things get messed up horribly then. In
this particular case it was BUG_ON(!irqs_disabled()) triggered in
run_posix_cpu_timers(), so we ended up shooting "current" with the
bursts of one SIGTRAP and three SIGILLs on every timer tick. ;-) -
Patch from Catalin Marinas
This patch calculates the AFS partition length by expanding the image
length information to the nearest erase block boundary. This
eliminates the problems with JFFS2 erasing the footer.Signed-off-by: Catalin Marinas

If CONFIG_SERIAL_8250_NR_UARTS is smaller than the array size in
asm/serial.h, we trampled on memory which wasn't ours. Take our
big boots away by limiting the number of ports initialised to the
smaller of ...NR_UARTS and the array size.Signed-off-by: Russell King

Patch from Catalin Marinas
This patch fixes the V bit setting for the ARM1020x processors. At
reset, this bit is automatically set to the value of the HIVECSINIT
input signal which just happened to be 1 but it is not mandatory.Signed-off-by: Catalin Marinas

Patch from Catalin Marinas
The new EABI gcc adds -mthumb-interwork by default, even if
-mabi=apcs-gnu is passed. This causes a warning for every compiled C
file when -march=armv4 is used. The patch adds -mno-thumb-interwork
if the option is supported. This is also useful since we don't need
any ARM/Thumb interworking in the kernelSigned-off-by: Catalin Marinas

On system boot up, there was an failure reported to boot.msg:
Trying to move old root to /initrd ... failed
According to initrd(4) man page, step #7 of BOOT-UP OPERATION
is described as below:
7. If the normal root file has directory /initrd, device
/dev/ram0 is moved from / to /initrd. Otherwise if
directory /initrd does not exist device /dev/ram0 is
unmounted.We got service calls from customers concerning about this failure message
at boot time. Many systems do not have /initrd and thus the message can be
changed in the case of non-existing /initrd so that it does not sound like
a failure of the system.Signed-off-by: Jay Lan

Currently selinux_sb_copy_data requires an entire page be allocated to
*orig when the function is called. This "requirement" is based on the fact
that we call copy_page(in_save, nosec_save) and in_save = orig when the
data is not FS_BINARY_MOUNTDATA. This means that if a caller were to call
do_kern_mount with only about 10 bytes of options, they would get passed
here and then we would corrupt PAGE_SIZE - 10 bytes of memory (with all
zeros.)Currently it appears all in kernel FS's use one page of data so this has
not been a problem. An out of kernel FS did just what is described above
and it would almost always panic shortly after they tried to mount. From
looking else where in the kernel it is obvious that this string of data
must always be null terminated. (See example in do_mount where it always
zeros the last byte.) Thus I suggest we use strcpy in place of copy_page.
In this way we make sure the amount we copy is always less than or equal to
the amount we received and since do_mount is zeroing the last byte this
should be safe for all.Signed-off-by: Eric Paris

This adds a single file, "bind", to the sysfs directory of every driver
registered with the driver core. To bind a device to a driver, write
the bus id of the device you wish to bind to that specific driver to the
"bind" file (remember to not add a trailing \n). If that bus id matches
a device on that bus, and it does not currently have a driver bound to
it, the probe sequence will be initiated with that driver and device.Note, this requires that the driver itself be willing and able to accept
that device (usually through a device id type table). This patch does
not make it possible to override the driver's id table.Signed-off-by: Greg Kroah-Hartman

The hvlpevent_queue (formally ItLpQueue) has a member called xInUseWord
which is used for serialising access to the queue. Because it's a word
(ie. 32 bit) there's a custom 32-bit version of test_and_set_bit() or
thereabouts in ItLpQueue.c.The xInUseWord is not shared with they hypervisor, so we can replace it
with a spinlock and remove the custom code.There is also another locking mechanism (ItLpQueueInProcess). This is
redundant because it's only manipulated while the lock's held. Remove it.Signed-off-by: Michael Ellerman
