2014-02-05pcihp: remove unused AcpiPciHpPciStatus.device_present fieldIgor Mammedov
Remove now unused 'device_present' field wich was obsoleted by patch "pcihp: reduce number of device check events" Signed-off-by: Igor Mammedov <imammedo@redhat.com> Reviewed-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2014-02-05pcihp: make pci_read() mmio calback compatible with legacy ACPI hotplugIgor Mammedov
due to recent change introduced by: "pcihp: reduce number of device check events" 'up' field is cleared right after it's read. This is incompatible with legacy BIOS ACPI code where PCNF ACPI method reads this field 32 times. To make pci_read mmio callback compatible with legacy 'up' behavior, pcihp code will need to know in which mode it runs add 'legacy_piix' field to AcpiPciHpState structure and alter register behavior accordingly.

2014-02-05pcihp: reduce number of device check eventsMichael S. Tsirkin
PIIX created a made-up value for the UP register since it was read by guest 32 times for each interrupt. There's no reason to do this for the new PCIHP: register is only read once for each interrupt, so clean up code by making read act as an interrupt acknowledgement: the new UP register clear on read. In this way we cut down the number of bus rescans by a factor of 32, and drop a bunch of code that's now unused. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>

2014-02-03linux-user: Fix trampoline code for CRISStefan Weil
__put_user can write bytes, words (2 bytes) or longwords (4 bytes). Here obviously words should have been written, but bytes were written, so values like 0x9c5f were truncated to 0x5f. Fix this by changing retcode from uint8_t to to uint16_t in target_signal_frame and also in the unused rt_signal_frame. This problem was reported by static code analysis (smatch).

This implements a subset of the AdvSIMD shift operations (namely all the none saturating or narrowing ones). The actual shift generation code itself is common for both the scalar and vector cases but wrapped with either vector element iteration or the fp reg access. The rounding operations need to take special care to correctly reflect the result of adding rounding bits on high bits as the intermediates do not truncate.
