The old code was: - kernel_code.start = virt_to_phys(_text); - kernel_code.end = virt_to_phys(__init_begin - 1); - kernel_data.start = virt_to_phys(_sdata); - kernel_data.end = virt_to_phys(_end - 1); If I look at one of my kernels: c0008000 T _text c0b5b000 R __end_rodata ... exception and unwind tables live here ... c0c00000 T __init_begin c0e00000 D _sdata c0e68870 D _edata c0e68870 B __bss_start c0e995d4 B __bss_stop c0e995d4 B _end So the original covers _text..__init_begin-1 which includes the exception and unwind tables. Your version above omits these, which leaves them exposed. -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 40Mbps down 10Mbps up. Decent connectivity at last!
