I've observed the following issues while building 2.6.37 + my devel branch. I don't believe any of them to be due to anything in my tree, so would be in 2.6.37 as well. === omap1 === arch/arm/plat-omap/built-in.o: In function `omap2_i2c_add_bus': arch/arm/plat-omap/i2c.c:169: undefined reference to `omap2_i2c_mux_pins' $ grep omap2_i2c_mux_pins arch/arm/*omap* -r arch/arm/mach-omap2/i2c.c:void __init omap2_i2c_mux_pins(int bus_id) arch/arm/plat-omap/i2c.c: omap2_i2c_mux_pins(bus_id); arch/arm/plat-omap/include/plat/i2c.h:void __init omap2_i2c_mux_pins(int bus_id); So, OMAP1 doesn't provide this symbol. === omap2 === arch/arm/plat-omap/devices.c:253: warning: âomap_init_wdtâ defined but not used arch/arm/mach-omap2/irq.c:64: warning: âintc_contextâ defined but not used arch/arm/mach-omap2/prcm.c:122: warning: âprcm_contextâ defined but not used Missing __maybe_unused or something else? It also comes with three section mismatches: WARNING: vmlinux.o(.text+0x1f4c4): Section mismatch in reference from the function omap_early_device_register() to the function .init.text:early_platform_add_devices() The function omap_early_device_register() references the function __init early_platform_add_devices(). This is often because omap_early_device_register lacks a __init annotation or the annotation of early_platform_add_devices is wrong. As early_platform_add_devices() is marked __init, so too should be omap_early_device_register(). WARNING: vmlinux.o(.text+0x1f6bc): Section mismatch in reference from the function omap_device_build_ss() to the function .init.text:early_platform_add_devices() The function omap_device_build_ss() references the function __init early_platform_add_devices(). This is often because omap_device_build_ss lacks a __init annotation or the annotation of early_platform_add_devices is wrong. This looks like omap_early_device_register() has been inlined into omap_device_build_ss(), and it doesn't look like it can be marked __init. Rather than passing an 'is_early_device' into this function, split out the common code into a separate function which takes a function pointer to the registration function. Then you can have two additional functions, one marked __init which uses omap_early_device_register() and one not marked __init using omap_device_register(). This also means that we get the init-section type checking further up the chain. WARNING: vmlinux.o(.data+0x6bd4): Section mismatch in reference from the variable h4_config to the (unknown reference) .init.data:(unknown) The variable h4_config references the (unknown reference) __initdata (unknown) If the reference is valid then annotate the variable with __init* or __refdata (see linux/init.h) or name the variable: *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console, Maybe it shouldn't be marked __initdata? === omap3 === WARNING: vmlinux.o(.text+0x1b780): Section mismatch in reference from the function sdp3430_twl_gpio_setup() to the function .init.text:omap2_hsmmc_init() The function sdp3430_twl_gpio_setup() references the function __init omap2_hsmmc_init(). This is often because sdp3430_twl_gpio_setup lacks a __init annotation or the annotation of omap2_hsmmc_init is wrong. Missing __init on sdp3430_twl_gpio_setup ? WARNING: vmlinux.o(.text+0x1f714): Section mismatch in reference from the function omap_early_device_register() to the function .init.text:early_platform_add_devices() The function omap_early_device_register() references the function __init early_platform_add_devices(). This is often because omap_early_device_register lacks a __init annotation or the annotation of early_platform_add_devices is wrong. As before. WARNING: vmlinux.o(.text+0x1f90c): Section mismatch in reference from the function omap_device_build_ss() to the function .init.text:early_platform_add_devices() The function omap_device_build_ss() references the function __init early_platform_add_devices(). This is often because omap_device_build_ss lacks a __init annotation or the annotation of early_platform_add_devices is wrong. As before. WARNING: vmlinux.o(.data+0x20670): Section mismatch in reference from the variable twl_driver to the function .init.text:twl_probe() The variable twl_driver references the function __init twl_probe() If the reference is valid then annotate the variable with __init* or __refdata (see linux/init.h) or name the variable: *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console, twl_probe shouldn't be __init ? === omap4 === Nothing apparantly new over omap3. -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
