0d2aac4ab1 target/arm/kvm: Do not silently remove PMU
kvm_arch_init_vcpu() used to remove PMU when it is not available even
if the CPU model needs one. It is semantically incorrect, and may
continue execution on a misbehaving host that advertises a CPU model
while lacking its PMU. Keep the PMU when the CPU model needs one, and
let kvm_arm_vcpu_init() fail if the KVM implementation mismatches with
our expectation.

8deba2f36e hw/arm/smmuv3: Assert input to oas2bits() is valid
Coverity has spotted a possible problem with the OAS handling
(CID 1558464), where the error return of oas2bits() -1 is not
checked, which can cause an overflow in oas value.

oas2bits() is only called with valid inputs, harden the function
to assert that.

546d574b11 hw/char/bcm2835_aux: Fix assert when receive FIFO fills up
When a bare-metal application on the raspi3 board reads the
AUX_MU_STAT_REG MMIO register while the device's buffer is
at full receive FIFO capacity
(i.e. `s->read_count == BCM2835_AUX_RX_FIFO_LEN`) the
assertion `assert(s->read_count < BCM2835_AUX_RX_FIFO_LEN)`

The ptem variable in ppc6xx_tlb_pte_check() is used only once,
simplify by removing it as the value is already clear itself without
adding a local name for it.

5a902297ee target/ppc/mmu_common.c: Remove local name for a constant
The mmask local variable is a less descriptive local name for a
constant. Drop it and use the constant directly in the two places it
is needed.

625b58fde8 target/ppc : Update VSX storage access insns to use tcg_gen_qemu _ld/st_i128.
Updated many VSX instructions to use tcg_gen_qemu_ld/st_i128, instead of using
tcg_gen_qemu_ld/st_i64 consecutively.
Introduced functions {get,set}_vsr_full to facilitate the above & for future use.

bf15bf0a1d target/ppc: Move get/set_avr64 functions to vmx-impl.c.inc.
Those functions are used to ld/st data to and from Altivec registers,
in 64 bits chunks, and are only used in vmx-impl.c.inc file,
hence the clean-up movement.
