2015-08-14mirror: Fix coroutine reentranceKevin Wolf
This fixes a regression introduced by commit dcfb3beb ("mirror: Do zero write on target if sectors not allocated"), which was reported to cause aborts with the message "Co-routine re-entered recursively". The cause for this bug is the following code in mirror_iteration_done(): if (s->common.busy) { qemu_coroutine_enter(s->common.co, NULL); } This has always been ugly because - unlike most places that reenter - it doesn't have a specific yield that it pairs with, but is more uncontrolled. What we really mean here is "reenter the coroutine if it's in one of the four explicit yields in mirror.c". This used to be equivalent with s->common.busy because neither mirror_run() nor mirror_iteration() call any function that could yield. However since commit dcfb3beb this doesn't hold true any more: bdrv_get_block_status_above() can yield. So what happens is that bdrv_get_block_status_above() wants to take a lock that is already held, so it adds itself to the queue of waiting coroutines and yields. Instead of being woken up by the unlock function, however, it gets woken up by mirror_iteration_done(), which is obviously wrong. In most cases the code actually happens to cope fairly well with such cases, but in this specific case, the unlock must already have scheduled the coroutine for wakeup when mirror_iteration_done() reentered it. And then the coroutine happened to process the scheduled restarts and tried to reenter itself recursively. This patch fixes the problem by pairing the reenter in mirror_iteration_done() with specific yields instead of abusing s->common.busy.

2015-08-13target-mips: simplify LWL/LDL mask generationAurelien Jarno
The LWL/LDL instructions mask the GPR with a mask depending on the address alignement. It is currently computed by doing: mask = 0x7fffffffffffffffull >> (t1 ^ 63) It's simpler to generate it by doing: mask = ~(-1 << t1) It uses one TCG instruction less, and it avoids a 32/64-bit constant loading which can take a few instructions on RISC hosts.

2015-08-13piix: Document coreboot-specific RAM size config registerEduardo Habkost
The existing i440fx initialization code sets a PCI config register that isn't documented anywhere in the Intel 440FX datasheet. Register 0x57 is DRAMC (DRAM Control) and has nothing to do with the RAM size. This was implemented in commit ec5f92ce6ac8ec09056be77e03c941be188648fa because old coreboot code tried to read registers 0x5a-0x5f,0x56,0x57 to get the RAM size from QEMU, but I couldn't find out why coreboot did that. I assume it was a mistake, and the original code was supposed to be reading the DRB[0-7] registers (offsets 0x60-0x67). Document that coreboot-specific register offset in a macro and a comment, for future reference.
