In 8250.c original ns16550 autoconfig code, we change the divisor latch when
we goto to high speed mode, we're assuming the previous speed is legacy. This
some times is not true.

For example in a system with both CONFIG_SERIAL_8250 and
CONFIG_SERIAL_8250_PNP set, in this case, the code (autoconfig) will be called
twice, one in serial8250_init/probe() and the other is from
serial_pnp_probe. When serial_pnp_probe calls the autoconfig for NS16550A,
it's already in high speed mode, change the divisor latch (quot << 3) in this
case will make the UART console garbled.

For any reason if the NS16550A was not work in high speed mode (e.g. we hold
NS16550A from going to high speed mode in autoconfig_16550a()), now we are
resume from suspend, we should also set the uartclk to the correct
value. Otherwise it is still the old 1843200 and that will bring issues.

seems there's no longer need for using con_buf/conf_buf_mtx
as vcs_read/vcs_write buffer for user's data.

The do_con_write function, that was the other user of this,
is currently using its own kmalloc-ed buffer.

Not sure when this got changed, as I was able to find this code
in 2.6.9, but it's already gone as far as current git history
goes - 2.6.12-rc2.

AFAICS there's a behaviour change with the current change.
The lseek is not completely mutually exclusive with the
vcs_read/vcs_write - the file->f_pos might get updated
via lseek callback during the vcs_read/vcs_write processing.

I tried to find out if the prefered behaviour is to keep
this in sync within read/write/lseek functions, but I did
not find any pattern on different places.

I guess if user end up calling write/lseek from different
threads she should know what she's doing. If needed we
could use dedicated fd mutex/buffer.

there's a race between vcs's lseek handler and VC release.

The lseek handler does not hold console_lock and touches
VC's size info. If during this the VC got released, there's
an access violation.

The inline assembly differences for v6 vs. v7 in the hvc_dcc
driver are purely optimizations. On a v7 processor, an mrc with
the pc sets the condition codes to the 28-31 bits of the register
being read. It just so happens that the TX/RX full bits the DCC
driver is testing for are high enough in the register to be put
into the condition codes. On a v6 processor, this "feature" isn't
implemented and thus we have to do the usual read, mask, test
operations to check for TX/RX full.

Since we already test the RX/TX full bits before calling
__dcc_getchar() and __dcc_putchar() we don't actually need to do
anything special for v7 over v6. The only difference is in
hvc_dcc_get_chars(). We would test RX full, poll RX full, and
then read a character from the buffer, whereas now we will test
RX full, read a character from the buffer, and then test RX full
again for the second iteration of the loop. It doesn't seem
possible for the buffer to go from full to empty between testing
the RX full and reading a character. Therefore, replace the v7
versions with the v6 versions and everything works the same.

Without marking the asm __dcc_getstatus() volatile my compiler
decides it can cache the value of __ret in a register and then
check the value of it continually in hvc_dcc_put_chars() (I had
to replace get_wait/put_wait with 1 and fixup the branch
otherwise my disassembler barfed on __dcc_(get|put)char).

00000000 <hvc_dcc_put_chars>:
   0:   ee103e11        mrc     14, 0, r3, cr0, cr1, {0}

  38:   e12fff1e        bx      lr

As you can see, the value of the mrc is checked against
DCC_STATUS_TX (bit 29) and then stored in r3 for later use.
Marking the asm volatile produces the following:

00000000 <hvc_dcc_put_chars>:
   0:   e3a03000        mov     r3, #0  ; 0x0

  10:   1afffffc        bne     8 <hvc_dcc_put_chars+0x8>
  14:   e7d10003        ldrb    r0, [r1, r3]
  18:   ee10fe11        mrc     14, 0, pc, cr0, cr1, {0}
  1c:   2afffffd        bcs     18 <hvc_dcc_put_chars+0x18>
  20:   ee000e15        mcr     14, 0, r0, cr0, cr5, {0}
  24:   e2833001        add     r3, r3, #1      ; 0x1
  28:   e1530002        cmp     r3, r2
  2c:   bafffff5        blt     8 <hvc_dcc_put_chars+0x8>
  30:   e1a00002        mov     r0, r2
  34:   e12fff1e        bx      lr

which looks better and actually works. Mark all the inline
assembly in this file as volatile since we don't want the
compiler to optimize away these statements or move them around
in any way.

On some platforms, we need to restore the console speed on resume even
it was not suspended (no_console_suspend), and on others we don't have
to do that.

So don't care about the "console_suspend_enabled" and unconditionally
reset the console speed if it is a console.

This is actually a redo of ba15ab0e (Set proper console speed on resume
if console suspend is disabled) from Deepak Saxena.  I also tried to
investigate more to find out if this change will break others, here is
what I've found out:

commit 891b9dd1
Author: Jason Wang <jason77.wang@gmail.com>
    serial-core: restore termios settings when resume console ports

commit ca2e71aa
Author: Jason Wang <jason77.wang@gmail.com>
    serial-core: skip call set_termios/console_start when no_console_suspend

commit 4547be78
Author: Stanislav Brabec <sbrabec@suse.cz>
    serial-core: resume serial hardware with no_console_suspend

commit ba15ab0e
Author: Deepak Saxena <dsaxena@laptop.org>
    Set proper console speed on resume if console suspend is disabled

from ba15ab0e, we learned that, even if the console suspend is disabled
(when no_console_suspend is set), we may still need to "reset the port
to the state it was in before we suspended."

Then with 4547be78, this piece of code is removed.

And then Jason Wang added that back in ca2e71aa and 891b9dd1, to fix
some breakage on OMAP3EVM platform. From ca2e71aa we learned that the
"set_termios" things is actually needed by both console is suspended
and not suspended.

That's why I removed the console_suspended_enabled condition, and only
call console_start() when we actually suspeneded it.

I also noticed in this thread:
http://marc.info/?t=129079257100004&r=1&w=2, which talked about on
some platforms, UART HW will be cut power whether or not we set
no_console_suspend, and then on resume it does not work quite well. I
have a similar HW, and this patch fixed this issue, don't know if this
patch also works on their platforms.

[Update: Stanislav tested this patch on Zaurus and reported it improves the
situation. Thanks.]

OMAP can do also dynamic idling so wake-up enable register should be set
also while system is running. If UART_OMAP_WER is not set, then for instance
the RX activity cannot wake up the UART port that is sleeping.

This RX wake-up feature was working when the 8250 driver was used instead
of omap-serial. Reason for this is that the 8250 doesn't set the
UART_OMAP_WER and then arch/arm/mach-omap2/pm34xx.c ends up saving and
restoring the reset default which is the same than value
OMAP_UART_WER_MOD_WKUP here.

Fix this by moving the conditional UART_OMAP_WER write from serial_omap_pm
into serial_omap_startup where wake-up bits are set unconditionally.

Allow non-ARM SMP processors to use the SMP_ON_UP feature.  CPUs

Then check for ARM11MPCore, which fails the MPIDR check.  Lastly check
the MPIDR reports multiprocessing extensions and that the CPU is part of
a multiprocessing system.
