uc: Handle freeing of multiple address spaces 2018-02-18 21:36:50 -05:00

exec: convert ram_list to QLIST 
QLIST has RCU-friendly primitives, so switch to it.

Backports commit 0d53d9fe8a0dcb849bc7c9836e9e6a287f9aa787 from qemu

exec.c: Don't set cpu->as until cpu_address_space_init 
Rather than setting cpu->as unconditionally in cpu_exec_init
(and then having target-i386 override this later), don't set
it until the first call to cpu_address_space_init.

This requires us to initialise the address space for
both TCG and KVM (KVM doesn't need the AS listener but
it does require cpu->as to be set).

For target CPUs which don't set up any address spaces (currently
everything except i386), add the default address_space_memory
in qemu_init_vcpu().

Backports commit 56943e8cc14b7eeeab67d1942fa5d8bcafe3e53f from qemu

fG! 1bef32fff6 Fix huge memory leak on uc_mem_protect() (#787) 
A memory region is allocated inside split_region() that was only freed in error case but not on success case, leading to huge memory leak if the region size was significant.

Ahmed Samy 02e6c14e12 x86: add MSR API via reg API (#755) 
Writing / reading to model specific registers should be as easy as
calling a function, it's a bit stupid to write shell code and run them
just to write/read to a MSR, and even worse, you need more than just a
shellcode to read...

So, add a special register ID called UC_X86_REG_MSR, which should be
passed to uc_reg_write()/uc_reg_read() as the register ID, and then a
data structure which is uc_x86_msr (12 bytes), as the value (always), where:
	Byte	Value		Size
	0	MSR ID		4
	4       MSR val		8
