Re: Fixed kernel entry point suggestion

[Adil Hafeez <adilhafeez80@gmail.com>]

What about placing the jump instruction just after reserved space, like this

 

        .text
        /*
         * Reserved space for exception handlers.
         * Necessary for machines which link their kernels at KSEG0.
         */
        .fill   0x400

        /* The following two symbols are used for kernel profiling. */
        EXPORT(stext)
        EXPORT(_stext)
=>     j kernel_entry
        __INIT

I disassembled vmlinux binary and now jump instruction is placed after reserved space

But certainly not _before_ .text. Also, it shouldn't move the reserved
space, it would need "align" instead of "space" afterwards.
