This patch allows to use a "real" SCSI tape with qemu using
"-drive /dev/sgX,if=scsi".
It allows to decode correctly transfer length when the type of the
device is a tape.
Some issues remain when the application reading the tape tries to go
beyond the end of the stream (but they must be corrected at the SCSI
controller level).
RedHat 9 shipped glibc 2.3. Modern versions of glibc do not have the aio thread
exit issue that the comment references. This patch adjusts the check to only
limit aio_init on glibc versions < 2.4.

Refactor AIO to allow multiple AIO implementations
This patch refactors the AIO layer to allow multiple AIO implementations. It's
only possible because of the recent signalfd() patch.
Right now, the AIO infrastructure is pretty specific to the block raw backend.
For other block devices to implement AIO, the qemu_aio_wait function must
support registration. This patch introduces a new function,
qemu_aio_set_fd_handler, which can be used to register a file descriptor to be
called back. qemu_aio_wait() now polls a set of file descriptors registered
with this function until one becomes readable or writable.
This patch should allow the implementation of alternative AIO backends (via a
thread pool or linux-aio) and AIO backends in non-traditional block devices
(like NBD).

LSI SCSI: raise UDC on infinite loop (Marcelo Tosatti)
Raise UDC (Unexpected Disconnect) when a large enough number of
instructions has been executed by the SCRIPTS processor. This "solution"
is much simpler than temporarily interrupting execution.
This remedies the situation with Windows which downloads SCRIPTS code
that busy loops on guest main memory. Their drivers _do_ handle UDC
appropriately (at least XP and 2003).
It would be nicer to actually detect infinite loops, but until then,
this bandaid seems acceptable.
Since the situation seems to be rare enough, raise the number
of instructions to 10000 (previously 1000).
Three people other than myself had success with this patch.
Swap only altered elements of the grouplist in getgroups() (Kirill Shutemov).
getgroups() returns the number of supplementary group IDs, so it's
unnessary to swap the entire array. It can dramatically speed up
the syscall: on recent Linux kernels NGROUPS_MAX=65536.

From Igor V. Kovalenko:
This openbios-grubfs-ext2fs-block.patch fixes a problem where inode
pointer is truncated to 32bit integer and then sign-extended to 64bit
integer while passing second pointer argument to ext2_rdfsb.

r233: Fix virtual to physical address translation (Igor Kovalenko)
r234: Implement itlb/dtlb directed writes (Igor Kovalenko)
r235: Fix warnings that would be caused by ld flag --warn-common
r236: Enable ld flag --warn-common
r237: Use the firmware device introduced in Qemu SVN r5256
misc tiny patches:
* add a 'check' target to the Makefile
* split code in crt.s to create the _exit syscall; also use the value of
main() as exit status
According to linux kernel sources, register a3 is set in case of failure
(and cleared in case of success) while register v0 contains the result
(or -errno in case of error).
The convention was not followed which results in weird behaviour.
[PATCH] usb-serial: Fix data corruption with usb serial emulation
* Remove the unused send_buf variable and its constant.
* Fix a math error
The variables recv_ptr and recv_used are not large enough to hold
the constant 384, which causes data corruption when the pointer is
reset with: s->recv_ptr = (s->recv_ptr + len) % RECV_BUF;

16550A UART: RHR irq enable bit also masks the Rx timeout irq.
The "Rx timeout" (aka. Character Timeout Indication) has no separate mask
bit in the IER register and according to the specs reading RHR is the only
way to reset the irq. However on the hardware (tested on OMAP2 UART which
is an extended 16550A) the RHR_IT bit in IER disables the irc, too. Linux
bluetooth serial dongle driver for N800 depends on this behavior.
The protocol_name "file" was added to the block driver when async IO was
introduced. This can be used to select that a file is treated as a raw
device instead of probing for the type. However, protocols are not subject
to path interpretation which cases qcow2 images with raw base images to not
function is the path was specified relatively.
The fix is simply to remove the protocol_name from the raw block driver. The
proper way to force the use of a raw block format is to use the format= option
with -drive.

Right now, kvm keeps the memory allocation split, so we can
handle different areas in different ways. This schema works with qemu
too, so it appears to be the common ground.
This patch proposes using this common ground for everyone, by spliting
raw qemu.

Make page_find() return 0 for too-large addresses (Eduardo Habkost)
On some cases, such as under KVM, tb_invalidate_phys_page_range()
may be called for large addresses, when qemu is configured to more than
4GB of RAM.
On these cases, qemu was crashing because it was using an index too
large for l1_map[], that supports only 32-bit addresses when compiling
without CONFIG_USER_ONLY.
Right now, we sprinkle #if defined(QEMU_IMG) && defined(QEMU_NBD) all over the
code. It's ugly and causes us to have to build multiple object files for
linking against qemu and the tools.
This patch introduces a new file, qemu-tool.c which contains enough for
qemu-img, qemu-nbd, and QEMU to all share the same objects.
This also required getting qemu-nbd to be a bit more Windows friendly. I also
changed the Windows block-raw to use normal IO instead of overlapping IO since
we don't actually do AIO yet on Windows. I changed the various #if 0's to
#if WIN32_AIO to make it easier for someone to eventually fix AIO on Windows.
After this patch, there are no longer any #ifdef's related to qemu-img and
qemu-nbd.

according to the alpha arch reference, the literal field of an operate
instruction is unsigned:
If bit <12> of the instruction is 1, an 8-bit zero-extended literal
constant is formed by bits
<20:13> of the instruction. The l teral is interpreted as a positive
integer bet ween 0 and 255
and is zero-extended to 64 bits.
This patch fixes the mis-interpretation of the literal field.
