 $ man ./qemu.1 | grep Tibor
        by Tibor "TS" SchA~Xtz.

This patch allows utf8 in man/pod docs.

Initially it was split into two parts and sent on 2012-02-02.
Resending it again (3rd time) now in merged form.  If any
other generalizations of $(POD2MAN) are needed it can be done
in a separate patch.  Current form of $(POD2MAN) is choosen
to be able to easily change it if some implementation does
not support utf8 or resulting output has issues with local
man(1) program/macros.

First, add @documentencoding in scripts/texi2pod.pl:

Currently our texi2pod ignores @documentencoding even if it is set
properly in *.texi files.  This results in a mojibake in documents
generated from qemu.pod (which is generated from qemu-doc.texi by
texi2pod), because the rest of the tools assumes ASCII encoding.

This patch recognizes first @documentencoding in input and places
it at the beginning of output as =encoding directive.

Second, run pod2man with --utf8 option to enable utf8 in manpages:

This option makes no difference for manpages which contains only
ascii chars.  But for manpages with actual UTF8 characters (qemu
docs contains these), this change allows to see real characters
instead of mojibakes or substitutes.

w64: Fix data type of next_tb and tcg_qemu_tb_exec

next_tb is the numeric value of a tcg target (= QEMU host) address.

Using tcg_target_ulong instead of unsigned long shows this and makes
the code portable for hosts with an unusual size of long (w64).

The type cast '(long)(next_tb & ~3)' was not needed (casting
unsigned long to long does not change the bits, and nor does
casting long to pointer for most (= all non w64) hosts.
It is removed here.

Macro or function tcg_qemu_tb_exec is used to set next_tb.
The function also returns next_tb. Therefore tcg_qemu_tb_exec
must return a tcg_target_ulong.

hw/pxa2xx.c: Fix handling of pxa2xx_i2c variable offset within region

The pxa2xx I2C controller can have its registers at an arbitrary offset
within the MemoryRegion it creates. We use this to create two controllers,
one which covers a region of size 0x10000 with registers starting at an
offset 0x1600 into that region, and a second one which covers a region
of size just 0x100 with the registers starting at the base of the region.

The implementation of this offsetting uses two qdev properties, "offset"
(which sets the offset which must be subtracted from the address to
get the offset into the actual register bank) and "size", which is the
size of the MemoryRegion. We were actually using "offset" for two
purposes: firstly the required one of handling the registers not being
at the base of the MemoryRegion, and secondly as a workaround for a
deficiency of QEMU. Until commit 5312bd8b3, if a MemoryRegion was mapped
at a non-page boundary, the address passed into the read and write
functions would be the offset from the start of the page, not the
offset from the start of the MemoryRegion. So when calculating the value
to set the "offset" qdev property we included a rounding to a page
boundary.

Following commit 5312bd8b3 MemoryRegion read/write functions are now
correctly passed the offset from the base of the region, and our
workaround now means we're subtracting too much from addresses, resulting
in warnings like "pxa2xx_i2c_read: Bad register 0xffffff90".
The fix for this is simply to remove the rounding to a page boundary;
this allows us to slightly simplify the expression since
  base - (base & (~region_size)) == base & region_size

The qdev property "offset" itself must remain because it is still
performing its primary job of handling register banks not being at
the base of the MemoryRegion.
