2011-03-03virtio-net: Fix lduw_p() pointer argument of wrong sizeStefan Hajnoczi
A pointer to a size_t variable was passed as the void * pointer to lduw_p() in virtio_net_receive(). Instead of acting on the 16-bit value this caused failure on big-endian hosts. Avoid this issue in the future by using stw_p() instead. In general we should use ld*_p() for loading from target memory and st*_p() for storing to target memory anyway, not the other way around. Also tighten up a correct use of lduw_p() when stw_p() should be used instead in virtio_net_get_config().

2011-03-03target-sh4: move intr_at_halt out of cpu_halted()Aurelien Jarno
All targets except SH4 have the same cpu_halted() routine, and it has only one caller. It is therefore a good candidate for inlining. The difference is the handling of the intr_at_halt, which is necessary to ignore SR.BL when sleeping. Move intr_at_halt handling out of it, by setting this variable while executing the sleep instruction, and clearing it when the CPU has been woken-up by an interrupt, whatever the state of SR.BL. Also rename this variable in_sleep. Cc: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

VMSTATE_PCIE_AER_ERRS is indeed useful for other emulation drivers. Move it to hw/hw.h under the name of VMSTATE_STRUCT_VARRAY_POINTER_UINT16. Also add VMSTATE_STRUCT_VARRAY_POINTER_INT32 which is more or less the same as _UINT16 macro, except the fact it uses int32_t internally.

2011-02-25HACKING: Update status of format checkingStefan Weil
Hopefully all functions with printf like arguments now use format checking. This was tested with default build configuration on linux and windows hosts (including some cross compilations), so chances are good that there remain few (if any) functions without format checking. Therefore the last comment in HACKING is no longer valid but misleading.

However sd.c was missing the state change to sd_sendingdata_state for these commands, with the effect that the Linux driver would either hang indefinitely waiting for nonexistent data (pl181) or read zeroes and provoke a qemu warning message (omap).

The frequency is pre-calculated every 500ms, based on the last 10 updates per 64x64 rect.
