2010-10-24KVM: x86 emulator: Add wrappers for easily defining opcodesAvi Kivity
Once 'struct opcode' grows, its initializer will become more complicated. Wrap the simple initializers in a D() macro, and replace the empty initializers with an even simpler N macro. Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
2010-10-24KVM: x86 emulator: introduce 'struct opcode'Avi Kivity
This will hold all the information known about the opcode. Currently, this is just the decode flags. Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
2010-10-24KVM: x86 emulator: drop parentheses in repreat macrosAvi Kivity

2010-10-24KVM: x86 emulator: Add IRET instructionMohammed Gamal
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.

2010-10-24KVM: x86 emulator: simplify Group 1 decodingAvi Kivity
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: Avi Kivity <avi@redhat.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
2010-10-24KVM: x86 emulator: mix decode bits from opcode and group decode tablesAvi Kivity
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: Avi Kivity <avi@redhat.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
2010-10-24KVM: x86 emulator: add Undefined decode flagAvi Kivity

2010-10-24KVM: x86 emulator: Make group storage bits separate from operand bitsAvi Kivity
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: Avi Kivity <avi@redhat.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>

2010-10-24KVM: x86 emulator: fix handling for unemulated instructionsAvi Kivity
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: Avi Kivity <avi@redhat.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>

2010-10-23block: fix use-after-free bug in blk throttle codeJens Axboe
blk_throtl_exit() frees the throttle data hanging off the queue in blk_cleanup_queue(), but blk_put_queue() will indirectly dereference this data when calling blk_sync_queue() which in turns calls throtl_shutdown_timer_wq(). Fix this by moving the freeing of the throttle data to when the queue is truly being released, and post the call to blk_sync_queue().

2010-10-23Revert "tty: Add a new file /proc/tty/consoles"Linus Torvalds
This reverts commit f4a3e0bceb57466c31757f25e4e0ed108d1299ec. Jiri Sladby points out that the tty structure we're using may already be gone, and Al Viro doesn't hold back in complaining about the random loading of 'filp->private_data' which doesn't have to be a pointer at all, nor does checking the magic field for TTY_MAGIC prove anything. Belated review by Al: "a) global variable depending on stdin of the last opener? Affecting output of read(2)? Really? b) iterator is broken; list should be locked in ->start(), unlocked in ->stop() and *NOT* unlocked/relocked in ->next() c) ->show() ought to do nothing in case of ->device == NULL, instead of skipping those in ->next()/->start() d) regardless of the merits of the bright idea about asterisk at that line in output *and* regardless of (a), the implementation is not only atrociously ugly, it's actually very likely to be a roothole. Verifying that Cthulhu knows what number happens to be address of a tty_struct by blindly dereferencing memory at that address... Ouch. Please revert that crap." And Christoph pipes in and NAK's the approach of walking fd tables etc too. So it's pretty unanimous.
