Ths patch adds IRET instruction (opcode 0xcf). Currently, only IRET in real mode is emulated. Protected mode support is to be added later if needed. Signed-off-by:

This patch fixes a bug in a nested hypervisor that heavily switches between real-mode and long-mode. The problem is fixed by syncing back efer into the guest vmcb on emulated vmexit. Signed-off-by:

Move operand decoding to the opcode table, keep lock decoding in the group table. This allows us to get consolidate the four variants of Group 1 into one group. Signed-off-by:

Allow bits that are common to all members of a group to be specified in the opcode table instead of the group table. This allows some simplification of the decode tables. Signed-off-by:

Add a decode flag to indicate the instruction is invalid. Will come in useful later, when we mix decode bits from the opcode and group table. Signed-off-by:

Avi Kivity authored
Currently group bits are stored in bits 0:7, where operand bits are stored. Make group bits be 0:3, and move the existing bits 0:3 to 16:19, so we can mix group and operand bits. Signed-off-by:

If an instruction is present in the decode tables but not in the execution switch, it will be emulated as a NOP. An example is IRET (0xcf). Fix by adding default: labels to the execution switches. Signed-off-by:

kvm reloads the host's fs and gs blindly, however the underlying segment descriptors may be invalid due to the user modifying the ldt after loading them. Fix by using the safe accessors (loadsegment() and load_gs_index()) instead of home grown unsafe versions. This is CVE-2010-3698. KVM-Stable-Tag. Signed-off-by:

This patch reverts the driver to enabling/disabling the NFC interrupt mask rather than enabling/disabling the system interrupt. This cleans up the driver so that it doesn't rely on interrupts being disabled within the interrupt handler. For i.MX21 we keep the current behaviour, that is calling enable_irq/disable_irq_nosync to enable/disable interrupts. This patch is based on earlier work by John Ogness. Signed-off-by:

Put the original syscall number into ->regs[0] when we leave syscall with error. Use it in restart logics. Everything else will have it 0 since we pass through SAVE_SOME on all the ways in. Note that in places like bad_stack and inllegal_syscall we leave it 0 - it's not restartable. Signed-off-by:

The i2c_imx_trx_complete() function is using wait_event_interruptible_timeout() to wait for the I2C controller to signal that it has completed an I2C bus operation. If the process that causes the I2C operation receives a signal, the wait will be interrupted, returning an error. It is better to let the I2C operation finished before handling the signal (i.e. returning into userspace). It is safe to use wait_event_timeout() instead, because the timeout will allow the process to exit if the I2C bus hangs. It's also better to allow the I2C operation to finish, because unacknowledged I2C operations can cause the I2C bus to hang. Signed-off-by:
