scsi-generic scsi_read_complete() should not -both- call the client complete callback with SCSI_REASON_DATA -and- call scsi_command_complete(). The former will cause the client to queue a new read or write request, while the later will free the request data structure, thus causing the new read or write request to use a freed/stale structure when it completes. This patch fixes the bug, fixing a crash with scsi-generic & RHEL5.5 installer.

If the input to a Neon float comparison is a quiet NaN, the ARM ARM specifies that we should raise InvalidOp if the comparison is GE or GT but not for EQ. (Signaling NaNs raise InvalidOp regardless). This means only EQ should use the _quiet version of the comparison function. We implement this by cleaning up the comparison helpers to call the appopriate versions of the softfloat simple comparison functions (float32_le and friends) rather than the generic float32_compare functions. This makes them simple enough that they are clearer opencoded rather than macroised. Signed-off-by: NPeter Maydell <peter.maydell@linaro.org> Signed-off-by: NAurelien Jarno <aurelien@aurel32.net>

The Neon versions of int-float conversions must use the "standard FPSCR" rather than the default FPSCR. Implement this by having the helper functions take a pointer to the appropriate float_status value rather than simply taking a pointer to the entire CPUState, and making translate.c pass a pointer to vfp.fp_status or vfp.standard_fp_status appropriately for whether the instruction being translated is Neon or VFP.

On ARM the architecture mandates that when an output denormal is flushed to zero we must set the FPSCR UFC (underflow) bit, so map softfloat's float_flag_output_denormal accordingly. Signed-off-by: NPeter Maydell <peter.maydell@linaro.org> Signed-off-by: NAurelien Jarno <aurelien@aurel32.net>

Add a new float_flag_output_denormal which is set when the result of a floating point operation would be denormal but is flushed to zero because we are in flush_to_zero mode. This is necessary because some architectures signal this condition as an underflow and others signal it as an inexact result.

If an op with dead outputs is not removed, because it has side effects or has multiple output and only one dead, mark the registers as dead instead of saving them. This avoid a few register spills on TCG targets with low register count, especially with div2 and mul2 ops, or when a qemu_ld* result is not used (prefetch emulation for example).

tb_invalidate_page_range() was intended to be used to invalidate an area of a TB which the guest explicitly flushes from i-cache. However, QEMU detects writes to code areas where TBs have been generated, so his has never been useful. Delete the function, adjust callers.

Early ppc64 CPUs include a hack to partially simulate the ppc32 segment registers, by translating writes to them into writes to the SLB. This is not used by any current Linux kernel, but it is used by the openbios used in the qemu mac99 model. Commit 81762d6d, cleaning up the SLB handling introduced a bug in this code, breaking the openbios currently in qemu. Specifically, there was an off by one error bitshuffling the register format used by mtsr into the format needed for the SLB load, causing the flag bits to end up in the wrong place. This caused the storage keys to be wrong under openbios, meaning that the translation code incorrectly thought a legitimate access was a permission violation. This patch fixes the bug, at the same time it fixes some build bug in the MMU debugging code (only exposed when DEBUG_MMU is enabled).

While trying out the > 64GB guest RAM patch, I hit some virtual address limitations of my host system, which resulted in mmap failing. Unfortunately, qemu didn't tell me about this failure, but just used the NULL pointer happily, resulting in either segmentation faults or other fun errors. To spare other users from tracing this down, let's print a nice message instead so the user can figure out what's wrong from there. Signed-off-by: NAlexander Graf <agraf@suse.de>

the s390 memory detection has a 16bit field that specifies the amount of increments. This patch adopts the memory size to always fit into that scheme.

the current s390x qemu memory layout is 0x1000000: guest start 0x80000000: qemu binary which limits the amount of available memory to <2GB.

The s390x virtio bus keeps management information on virtio after the top of the guest's RAM. We need to be able to tell the guest the size of its RAM (without virtio stuff), but also be able to trap when the guest accesses RAM outside of its scope (including virtio stuff). So we need a variable telling us the size of the virtio stuff, so we can calculate the highest available RAM address from that. While at it, also increase the maximum number of virtio pages, so we play along well with more recent kernels that spawn a ridiculous number of virtio console adapters.
