Input: wm97xx - enable sub-drivers by default
Currently the support for each WM97xx touchscreen model is compiled out
by default, meaning that the default configuration when the driver is
built is for it to support no hardware. This is suboptimal and leads to
problems like distribution kernels shipping a non-functional driver.
Change the default to support all controllers and update the help text
to reflect this.

initrd: Fix virtual/physical mix-up in overwrite test
On recent kernels, I get the following error when using an initrd:
| initrd overwritten (0x00b78000 < 0x07668000) - disabling it.
My Amiga 4000 has 12 MiB of RAM at physical address 0x07400000 (virtual
0x00000000).
The initrd is located at the end of RAM: 0x00b78000 - 0x00c00000 (virtual).
The overwrite test compares the (virtual) initrd location to the (physical)
first available memory location, which fails.
This patch converts initrd_start to a page frame number, so it can safely be
compared with min_low_pfn.
Before the introduction of discontiguous memory support on m68k
(12d810c1b8c2b913d48e629e2b5c01d105029839), min_low_pfn was just left
untouched by the m68k-specific code (zero, I guess), and everything worked
fine.

Subject: [PATCH 1/2] serial: Add flush_buffer() operation to uart_ops
Serial drivers using DMA (like the atmel_serial driver) tend to get very
confused when the xmit buffer is flushed and nobody told them. They
also tend to spew a lot of garbage since the DMA engine keeps running
after the buffer is flushed and possibly refilled with unrelated data.
This patch adds a new flush_buffer operation to the uart_ops struct,
along with a call to it from uart_flush_buffer() right after the xmit
buffer has been cleared. The driver can implement this in order to
syncronize its internal DMA state with the xmit buffer when the buffer
is flushed.
