2014-11-03block/iscsi: use sector_limits_lun2qemu throughout iscsi_refresh_limitsPeter Lieven
As Max pointed out there is a hidden cast from int64_t to int for all limits. So use the newly introduced sector_limits_lun2qemu for all limits received from the target.

Copy the max_xfer_len from the BlockLimits VPD or use the maximum value fitting in the CDB. The helper function sector_limits_lun2qemu is introduced to convert and cap the limits from the VPD to the maximum power of two fitting in an integer; integer is the range for nb_sectors throughout the block layer.

2014-11-03util: introduce MIN_NON_ZEROPeter Lieven
at least in block layer we have the case of limits being defined for a BlockDriverState. However, in this context often zero (0) has the special meanining of undefined which means no limit. If two of those limits are combined and the minimum is needed the minimum function should only return zero if both parameters are zero.

2014-10-28libcacard: Lock NSS cert db when selecting an applet on an emulated cardRay Strode
When a process in a guest uses an emulated smartcard, libcacard running on the host passes the PIN from the guest to the PK11_Authenticate NSS function. The first time PK11_Authenticate is called the passed in PIN is used to unlock the certificate database. Subsequent calls to PK11_Authenticate will transparently succeed, regardless of the passed in PIN. This is a convenience for applications provided by NSS. Of course, the guest may have many applications using the one emulated smart card all driven from the same host QEMU process. That means if a user enters the right PIN in one program in the guest, and then enters the wrong PIN in another program in the guest, the wrong PIN will still successfully unlock the virtual smartcard. This commit forces the NSS certificate database to be locked anytime an applet is selected on an emulated smartcard by calling vcard_emul_logout.

2014-10-24target-arm: correctly UNDEF writes to FPINST/FPINST2 from EL0Peter Maydell
The ARM ARM requires that the FPINST and FPINST2 VFP control registers are not accessible to code at EL0. We were already correctly implementing this for reads of these registers; add the missing check for the write code path.

2014-10-24target-arm: Report a valid L1Ip field in CTR_EL0 for CPU type "any"Peter Maydell
For the CPU type "any" (only used with linux-user) we were reporting the L1Ip field as 0b00, which is reserved. Change this field to 0b10 instead, indicating a VIPT icache as the comment describes.

2014-10-24target-arm: Correct sense of the DCZID DZP bitPeter Maydell
The DZP bit in the DCZID system register should be set if the control bits which prohibit use of the DC ZVA instruction have been set (it stands for Data Zero Prohibited). However we had the sense of the test inverted; fix this so that the bit reads correctly. To avoid this regressing the behaviour of the user-mode emulator, we must set the DZE bit in the SCTLR for that config so that userspace continues to see DZP as zero (it was getting the correct result by accident previously).

2014-10-24arm/virt: enable PSCI emulation support for system emulationRob Herring
Now that we have PSCI emulation, enable it for the virt platform. This simplifies the virt machine a bit now that PSCI no longer needs to be a KVM only feature.

2014-10-24target-arm: add emulation of PSCI calls for system emulationRob Herring
Add support for handling PSCI calls in system emulation. Both version 0.1 and 0.2 of the PSCI spec are supported. Platforms can enable support by setting the "psci-conduit" QOM property on the cpus to SMC or HVC emulation and having a PSCI binding in their dtb.
