Introduce unregister_/register_kprobes() for kprobe batch registration. This

Prohibit users from probing preempt_schedule(). One way of prohibiting the
user from probing functions is by marking such functions with __kprobes. But
this method doesn't work for those functions, which are already marked to
different section like preempt_schedule() (belongs to __sched section). So we
use blacklist approach to refuse user from probing these functions.In blacklist approach we populate the blacklisted function's starting address
and its size in kprobe_blacklist structure. Then we verify the user specified
address against start and end of the blacklisted function. So any attempt to
register probe on blacklisted functions will be rejected.[akpm@linux-foundation.org: build fix]

This patch extends the sm501 mfd with 8250 uart support. We're currently
doing this in the board specific r2d-1 code already, but it would be nice to
do move things into the mfd since it's more chip specific than board specific.Signed-off-by: Magnus Damm

Updates to the i.MX SPI controller driver:
1) Some comments changed and/or added.
2) End of transfers is now managed on TXFIFO empty interrupt after the
last write to TXFIFO. This speeds interrupt execution by removing
the wait for TXFIFO to become empty. On TXFIFO empty interrupt the
handler needs only to poll for the end of the ongoing transaction
(SPI_CONTROL_XCH) to close the transfer.
(2.1) Write only transfers are closed flushing RXFIFO.
(2.2) Read transfers are closed reading trailing bytes from RXFIFO.
(2.3) Read transfers where RXFIFO overrun occurred are closed by
flushing RXFIFO and aborting the message.3) Fifos are now flushed via SPI disable after the end of ongoing
transaction.Signed-off-by: Andrea Paterniani

Turn CONFIG_DMI into a selectable option if EMBEDDED is defined, in
order to be able to remove the DMI table scanning code if it's not
needed, and then reduce the kernel code size.With CONFIG_DMI (i.e before) :
text data bss dec hex filename
1076076 128656 98304 1303036 13e1fc vmlinuxWithout CONFIG_DMI (i.e after) :
text data bss dec hex filename
1068092 126308 98304 1292704 13b9a0 vmlinuxResult:

Thomas Koeller had reported an issue where a device that had been making use
of the UART_BUG_TXEN code in the 8250 driver was mistakenly being caught by
the backup timer test, causing the device to work improperly.To fix this, tighten the test requirements to enable the backup timer
workaround.The backup timer is really meant to catch UARTs that don't re-assert the THRE
interrupt. The expectation is that they do initially assert THRE. This patch
clarifies the test.Signed-off-by: Alex Williamson

Russell King noticed this one: We have to avoid replacing B0 when we pick a
baud rate for a "hung up" port. Ugly but the proper fix is in the tty layer

We try and write the correct speed back but the serial midlayer already
mangles the speed on us and that means if we request B0 we report back B9600
when we should not. For now we'll hack around this in the drivers and serial
code, pending a better long term solution.Signed-off-by: Alan Cox
