2012-12-06target-mips: Fix incorrect shift for SHILO and SHILOVPetar Jovanovic
helper_shilo has not been shifting an accumulator value correctly for negative values in 'shift' field. Minor optimization for shift=0 case. This change also adds tests that will trigger issue and check for regressions.

Hotplugging them simply doesn't work, so tag them accordingly to avoid users trying and then crashing qemu.

2012-11-28virtio-scsi: Fix subtle (guest) endian bugDavid Gibson
The virtio-scsi config space is, by specification, in guest endian (which is ill-defined, but there you go). In virtio_scsi_get_config() we set up all the fields in there, using stl_raw(). Which is a problem for the max_channel and max_target fields, which are 16-bit, not 32-bit. For little-endian targets we get away with it by accident, since the first two bytes will still be correct, and the extra two bytes written (with zeroes) will be overwritten correctly by the next store. But for big-endian guests, this means the max_target field ends up as zero, which means the guest will only recognize a single disk on the virtio-scsi bus. This patch fixes the problem.

2012-11-28virtio-scsi: Fix some endian bugs with virtio-scsiDavid Gibson
The virtio-scsi specification does not specify the correct endianness for fields in the request structure. It's therefore best to assume that it is "guest native" endian since that's the (stupid and poorly defined) norm in virtio. However, the qemu device for virtio-scsi has no byteswaps at all, and so will break if the guest has different endianness from the host. This patch fixes it by adding tswap() calls for the sense_len and resid fields in the request structure. In theory status_qualifier needs swaps as well, but that field is never actually touched. The tag field is a uint64_t, but since its value is completely arbitrary, it might as well be uint8_t[8] and so it does not need swapping.

2012-11-27rtc: Only call rtc_set_cmos when Register B SET flag is disabled.Alex Horn
This bug occurs when the SET flag of Register B is enabled. When an RTC data register (i.e. any of the ten time/calender CMOS bytes) is set, the data is (as expected) correctly stored in the cmos_data array. However, since the SET flag is enabled, the function rtc_set_time is not invoked. As a result, the field base_rtc in RTCState remains uninitialized. This causes a problem on subsequent writes which can end up overwriting data. To see this, consider writing data to Register A after having written data to any of the RTC data registers; the following figure illustrates the call stack for the Register A write operation: +- cmos_io_port_write +-- check_update_timer +---- get_next_alarm +------ rtc_update_time In rtc_update_time, get_guest_rtc calculates the wrong time and overwrites the previously written RTC data register values.
