Merge remote-tracking branch 'remotes/pmaydell/tags/pull-misc-20150120' into staging
Miscellaneous cross-tree patches: * load/store helper cleanup * drop TARGET_HAS_ICE define and checks * scripts/qapi-types.py: Add dummy member to empty structs * cpu_ldst.h: Don't define helpers if MMU_MODE*_SUFFIX not defined # gpg: Signature made Tue 20 Jan 2015 15:43:38 GMT using RSA key ID 14360CDE # gpg: Good signature from "Peter Maydell <peter.maydell@linaro.org>" * remotes/pmaydell/tags/pull-misc-20150120: cpu_ldst.h: Don't define helpers if MMU_MODE*_SUFFIX not defined cpu_ldst.h, cpu-all.h, bswap.h: Update documentation on ld/st accessors cpu_ldst_template.h: Drop unused cpu_ldfq/stfq/ldfl/stfl accessors cpu_ldst.h: Drop unused _raw macros, saddr() and laddr() cpu_ldst_template.h: Use ld*_p directly rather than via ld*_raw macros cpu_ldst.h: Use inline functions for usermode cpu_ld/st accessors cpu_ldst.h: Remove unused very short ld*/st* defines cpu_ldst.h: Drop unused ld/st*_kernel defines target-mips: Don't use _raw load/store accessors linux-user/main.c (m68k): Use get_user_u16 rather than lduw in cpu_loop linux-user/vm86.c: Use cpu_ldl_data &c rather than plain ldl &c bsd-user/elfload.c: Don't use ldl() or ldq_raw() linux-user/elfload.c: Don't use _raw accessor functions target-sparc: Don't use {ld, st}*_raw functions monitor.c: Use ld*_p() instead of ld*_raw() cpu_ldst.h: Remove unused ldul_ macros exec.c: Drop TARGET_HAS_ICE define and checks scripts/qapi-types.py: Add dummy member to empty structs Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
