  • e1000: Do not reinit pci config space to 0 ...
    4a794a62 
    pci_register_device already mallocs the pci config space buffer filled
with zeroes.

Doing this again breaks some default config space writes like
setting the subsystem vendor id and subsystem device id.

  • AIO deletion race fix ...
    79d5ca56 
    When deleting an fd event there is a chance the object doesn't get
deleted, but only ->deleted set positive and deleted somewhere later.

Now, if we create a handler for the fd again before the actual
deletion occurs, we end up writing data into an object that has
->deleted set, which is obviously wrong.

I see two ways to fix this:

1. Don't return ->deleted objects in the search
2. Unset ->deleted in the search

This patch implements 1. which feels safer to do. It fixes AIO issues
I've seen with curl, as libcurl unsets fd event listeners pretty
frequently.

  • reset state for load_linux ...
    d6ecb036 
    The linux loader is just an option rom like any other, just with
some special requirements. Right now, our option rom resetting
mechanism is not being applied to it. As a result, users using
-kernel will not be able to successfully reboot their machines

This patch fixes it by saving all the data we generated in
the load_linux() function, to be used later by the option rom
resetting mechanism.

  • register reset handler for option_roms ...
    e28f9884 
    Currently, boot options are not preserved across a system reset.
option roms can modify themselves, or can for instance restore the real
int 0x19 vector after they tried to boot from it.

To properly do that, we need a reset handler registered to deal with option
roms. This patch is based on current version on qemu-kvm.git

  • Drop CONFIG_GDBSTUB ...
    322f9d01 
    This is no user-flippable switch, and no arch makes use of disabling
gdbstub support. So it's pointless to keep the related #ifdefs and
configure hunks around - and risking breakages like 711c410fdd again.

  • Fix disassembler memory accesses ...
    e612a1f7 
    Sparc disassembler wants to check previous addresses for some stuff
and this may actually cause faults to be generated to the guest if the
address is close to page start, because of the function used for the
memory access.

Fix by changing ldub_code to cpu_memory_rw_debug, which doesn't trigger
exceptions.

    0087375e 
    We already print a directory prefix in non-verbose mode, so there's no
point printing a messages when recursive make enters/leaves a directory.
