The patchset adds a generic can_be_deleted callback to UserCreatableClass.
It prevents removing a usercreatable object if the callback returns false.
Backends could implement the callback if it shoudn't be removed while it's
in use.

Hi,
Here are a few patches preparing for and adding AArch64 Angel
semihosting support. I've been testing them with some simple tests from
the following repository. This series only adds support for exit, but
support for the rest of the calls will hopefully follow shortly.
http://git.linaro.org/p
This will allow the print-error-and-exit sequence to be called from a
second location in a subsequent patch. The type of the nr variable is
changed from int to uint32_t since I'm unaware of semihosting call
numbers needing more than 32 bits, even on AArch64. Also generalize
the wording of the unsup
In AArch64, Angel semihosting uses HLT instructions with a special
immediate value, 0xf000. Use a new exception type EXCP_SEMI for this,
since I'm not aware of plans for full HLT support, and EXCP_HLT is
already defined as a QEMU internal exception type. Support just the
exit call in A64 to start w
The FIS Receive Buffer and Command List Buffer pointers
should not be edited while the FIS receive engine or
Command Receive engines are running.
Currently, we attempt to re-map the buffers every time they
are adjusted, but while the AHCI engines are off, these registers
may contain stale values,
Many bits in the CMD register are supposed to be strictly read-only.
We should not be deleting them on every write.
As a side-effect: pay explicit attention to when a guest marks off
the FIS Receive or Start bits, and disable the status bits ourselves,
instead of letting them implicitly fall off.
