It was added "#include " to ARM's "" as it uses uint_{16,32}t in 'struct bug_frame'. 2. It was added '#define BUG_FRAME_STRUCT' which means that ARM hasn't been switched to generic implementation yet. 3. It was added '#define BUG_FRAME_STRUCT' which means that x86 hasn't been switched to generic implementation yet. 4. BUGFRAME_* and _start_bug_frame[], _stop_bug_frame_*[] were removed for ARM & x86 to deal with compilation errors such as: redundant redeclaration of ... 5. Remove BUG_DISP_WIDTH, BUG_LINE_LO_WIDTH, BUG_LINE_HI_WIDTH from x86's to not to produce #undef for them and #define again with the same values as in . These #undef and #define will be anyway removed in the patch [2] 6. Remove from and as nothing from are used in <*/cpufreq.c> In the following two patches x86 and ARM archictectures will be switched fully: [1] xen/arm: switch ARM to use generic implementation of bug.h [2] xen/x86: switch x86 to use generic implemetation of bug.h Signed-off-by: Oleksii Kurochko Reviewed-by: Jan Beulich --- Changes in V8: * remove from and as nothing from are used in <*/cpufreq.c> * update the commit message --- Changes in V7: * Remove #undef {BUG_DISP_WIDTH, BUG_LINE_LO_WIDTH, BUG_LINE_HI_WIDTH} from ARM and x86: * for ARM was created separate patch where the defines are removed as unused. * for x86, the defines were removed now not to produce #undef of them to= remove them again in the following-up patch * Update commit message * Add Reviewed-by: Jan Beulich --- Changes in V6: - change the inclusion order of . - add #undef of BUG_DISP_WIDTH, BUG_LINE_LO_WIDTH for ARM & x86 as they were introduced unconditionally in . - update the commit message --- Changes in V5: - Nothing changed --- Changes in V4: - defines BUG_DISP_WIDTH, BUG_LINE_LO_WIDTH, BUG_LINE_HI_WIDTH were moved = into "ifndef BUG_FRAME_STRUCT" in as they are specific for 'struc= t bug_frame' and so should co-exist together.
