eae936e21b [PATCH] serial: update NEC VR4100 series serial support
- Changed the return value of unknown type to NULL.

- Deleted the NULL check of dev_id in siu_interrupt().

- Deleted the NULL check of port->membase in siu_shutdown().

- Added the NULL check of port->membase to siu_startup().

- Removed early_uart_ops. Now using vr41xx_siu standerd one.

- Changed KSEG1ADDR() in siu_console_setup() to ioremap().

- When uart_add_one_port() failed, changed to set NULL to port->dev.

857dde2e79 When we detect that a 16550 was in fact part of a NatSemi SuperIO chip
with high-speed mode enabled, we switch it to high-speed mode so that
baud_base becomes 921600. However, we also need to multiply the baud
divisor by 8 at the same time, in case it's already in use as a console.

f1fc3990e2 [PATCH] serial_cs device identification fix
serial_cs's vendor/device identification got broken by Yum Rayan's change
'[PATCH] serial_cs: Reduce stack usage in serial_event()' - it changed buf
type from u_short* to char*, breaking device manufacturer & card number
retrieval.  Due to this my modem stopped from being recognized as special
case.

Code will work much better if we'll rely on first_tuple's parser instead of
doing parse ourselves.  Code also looks simpler after change.

This patch reduces the stack usage of the function serial_event() in
serial_cs from 2212 to 228.  I used a patched version of gcc 3.4.3 on i386
with -fno-unit-at-a-time disabled.

This patch is only compile tested.

587897f51f [PATCH] ARM: 2654/1: i.MX UART initialization sets and honors UFCR value
Patch from Sascha Hauer

This patch adds UCFR_RFDIV setting into i.MX serial driver.
This is required, if loader does not fully agree with Linux kernel
about UART setup manner. Linux only blindly expected some values until
now. This should enable to use even serial ports not recognized by
boot-loader as for example third UART found in the bluethoot module.
Patch also enables to detect original setup baudrate in more cases.

623f41eb92 [SPARC64]: In sunsu driver, make sure to fully init chip for kbd/ms
We were forgetting to call sunsu_change_speed().  The reason
that replugging in the mouse cable "fixes things" is that
causes a BREAK interrupt which in turn caused a call to
sunsu_change_speed() which would get the chip setup properly.

23907eb8c2 [PATCH] serial: fix comments in 8250.c
Fix the formatting of some comments in 8250.c, and add a note that the
register_serial / unregister_serial shouldn't be used in new code.

We do this here in preference to adding to linux/serial.h, since that is used
by a number of non-8250 drivers which pretend to be 8250.  It is not known
whether it would be appropriate to do so.

614a7d6a76 [PATCH] fix up newly added jsm driver
- plug various leaks and use after frees in the remove and
   initialization failure path (some still left)
 - remove useless global list of boards and use pci_set_drvdata instead
 - unobsfucate init path by merging functions together
 - kill various totally useless state variables
 - .. probably more I forgot

Note that the tty part still generates lots of sparse warnings and there's
still a totally useless layer of function pointer indirections, but maybe
someone else will fix that bit up.

1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
