618c169b57 usb: rework attach/detach workflow
Add separate detach callback to USBPortOps, split
uhci/ohci/musb/usbhub attach functions into two.

Move common code to the usb_attach() function, only
the hardware-specific bits remain in the attach/detach
callbacks.

Keep track of the port it is attached to for each usb device.

a980a065fb usb: move USB_REQ_{GET,SET}_CONFIGURATION handling to common code
This patch adds fields to the USBDevice struct for the current
speed (hard-wired to full speed for now) and current device
configuration.  Also a init function is added which inializes
these fields.  This allows USB_REQ_{GET,SET}_CONFIGURATION
handling to be moved to common code.

For most drivers the conversion is trivial ad they support a single
configuration only anyway.  One exception is bluetooth where some
device-specific setup code runs after get/set configuration.  The
other is usb-net which actually has two configurations so the
the code to check for the active configuration has been adapted.

f29783f72e usb serial: use new descriptor infrastructure.
Switch the usb serial drivers (serial, braille) over to the
new descriptor infrastructure.

Note that this removes the freely configurable vendor and product id
properties.  I think the only reason this was configurable is that the
only difference between the serial and the braille device is the
vendor+product id.  Of course the serial and braille devices keep their
different IDs, but they can't be overritten from the command line any
more.

37fb59d303 usb: data structs and helpers for usb descriptors.
This patch adds hw/usb-desc.[ch] files.  They carry data structures
for various usb descriptors and helper functions to generate usb
packets from the structures.

The intention is to have a internal representation of the device
desription which is more usable than the current char array blobs,
so we can have common code handle common usb device emulation using
the device description.

The usage of this infrastructure is optional for usb drivers as there
are cases such as pass-through where it probably isn't very useful.

8aaf42ed0f slirp: fix unaligned access in bootp code
Slirp code tries to be smart an avoid data copy by using pointer to
the data. This solution leads to unaligned access, in this case
preq_addr, which is a 32-bit long structure. There is no real point
of avoiding data copy in a such case, as the value itself is smaller
or the same size as a pointer.

The patch replaces pointers to the preq_addr structure by the strcture
itself, and use the address 0.0.0.0 if no address has been requested
(this is not a valid address in such a request). It compares it with
htonl(0L) for correctness reasons, in case a code checker look for such
mistakes. It also uses memcpy() for copying the data, which takes care
of alignement issues.

This fixes an unaligned access on IA64 host while requesting a DHCP
address.

0f11f25a00 tcg/arm: improve constant loading
Improve constant loading in two ways:
- On all ARM versions, it's possible to load 0xffffff00 = -0x100 using
  the mvn rd, #0. Fix the conditions.
- On <= ARMv6 versions, where movw and movt are not available, load the
  constants using mov and orr with rotations depending on the constant
  to load. This is very useful for example to load constants where the
  low byte is 0. This reduce the generated code size by about 7%.

Also fix the coding style at the same time.

829a49274f target-sh4: improve TLB
SH4 is using 16-bit instructions which means most of the constants are
loaded through a constant pool at the end of the subroutine. The same
memory page is therefore accessed in exec and read mode.

With the current implementation, a QEMU TLB entry is set to read or
read/write mode after an UTLB search and to exec mode after an ITLB
search, which causes a lot of TLB exceptions to switch from read or
read/write to exec and vice versa.

This patch optimizes that by already setting the QEMU TLB entry in read
or read/write mode when an UTLB entry is copied into ITLB (during an
ITLB miss). This improve the emulation speed by about 14%.

c69806ab82 tcg/arm: fix branch target change during code retranslation
QEMU uses code retranslation to restore the CPU state when an exception
happens. For it to work the retranslation must not modify the generated
code. This is what is currently implemented in ARM TCG.

However on CPU that don't have icache/dcache/memory synchronised like
ARM, this requirement is stronger and code retranslation must not modify
the generated code "atomically", as the cache line might be flushed
at any moment (interrupt, exception, task switching), even if not
triggered by QEMU. The probability for this to happen is very low, and
depends on cache size and associativiy, machine load, interrupts, so the
symptoms are might happen randomly.

This requirement is currently not followed in tcg/arm, for the
load/store code, which basically has the following structure:
  1) tlb access code is written
  2) conditional fast path code is written
  3) branch is written with a temporary target
  4) slow path code is written
  5) branch target is updated
The cache lines corresponding to the retranslated code is not flushed
after code retranslation as the generated code is supposed to be the
same. However if the cache line corresponding to the branch instruction
is flushed between step 3 and 5, and is not flushed again before the
code is executed again, the branch target is wrong. In the guest, the
symptoms are MMU page fault at a random addresses, which leads to
kernel page fault or segmentation faults.

The patch fixes this issue by avoiding writing the branch target until
it is known, that is by writing only the branch instruction first, and
later only the offset.

This fixes booting linux guests on ARM hosts (tested: arm, i386, mips,
mipsel, sh4, sparc).

3ebe80c299 linux-user: Fix incorrect NaN detection in ARM nwfpe emulation
The code in the linux-user ARM nwfpe emulation was incorrectly
checking only for quiet NaNs when it should have been checking
for any kind of NaN. This is probably because the code in
question was taken from the Linux kernel, whose copy of the
softfloat library had been modified so that float*_is_nan()
returned true for all NaNs, not just quiet ones. The qemu
equivalent function is float*_is_any_nan(), so use that.
NB that this code is really obsolete since nobody uses FPE
for actual arithmetic now; this is just cleanup following
the recent renaming of the NaN related functions.
