In the new decode, our asimd_imm_const() function returns a 64-bit value rather than a 32-bit one, which means we don't need to treat cmode=14 op=1 as a special case in the decoder (it is the only encoding where the two halves of the 64-bit value are different).

2020-06-01target/mips: Support variable page sizeHuacai Chen1-0/+5
Traditionally, MIPS use 4KB page size, but Loongson prefer 16KB page size in system emulator. So, let's define TARGET_PAGE_BITS_VARY and TARGET_PAGE_BITS_MIN to support variable page size.

2020-05-27i386: Fix x86_cpu_load_model() error API violationMarkus Armbruster1-10/+17
The Error ** argument must be NULL, &error_abort, &error_fatal, or a pointer to a variable containing NULL. Passing an argument of the latter kind twice without clearing it in between is wrong: if the first call sets an error, it no longer points to NULL for the second call. x86_cpu_load_model() is wrong that way. Harmless, because its @errp is always &error_abort. To fix, cut out the @errp middleman.

2020-05-27s390x/cpumodel: Fix harmless misuse of visit_check_struct()Markus Armbruster1-1/+1
Commit e47970f51d "s390x/cpumodel: Fix query-cpu-model-FOO error API violations" neglected to change visit_check_struct()'s Error ** argument along with the others. If visit_check_struct() failed, we'd take the success path. Fortunately, it can't fail here: qobject_input_check_struct() checks we consumed the whole dictionary, and to get here, we did. Fix it anyway.
