Russell King 55d3b282b9 [PATCH] Serial: Mobility's 16550A ports need a helping hand
The Mobility 16550A serial ports don't behave the same as standard
16550A ports, and need a helping hand to get them going once the
transmitter has drained and been disabled.

Russell King 4ba5e35daa [PATCH] Serial: Convert 8250 revision-based bug fixes to bug bitmask
For some 8250 port types, we used to check the type of the port, and
then determine whether the chip revision means the device is buggy.
Instead, introduce a bit array, and set the appropriate bit(s) when
we discover a buggy device.

David Woodhouse 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.

Russell King 05ab301463 [PATCH] Serial: Add uart_insert_char()
Add uart_insert_char(), which handles inserting characters into the
flip buffer.  This helper function handles the correct semantics
for handling overrun in addition to inserting normal characters.

Adrian Bunk 408b664a7d [PATCH] make lots of things static
Another large rollup of various patches from Adrian which make things static
where they were needlessly exported.

Russell King 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.

Linus Torvalds 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!
