Value:

{     \
        __asm__ volatile (      \
        "la     $8, 1f\n\t"     \
        "lui    $9, 0x8000\n\t" \
        "or     $8, $9\n\t"     \
        "jr     $8\n\t"         \
        " nop\n\t"              \
        "1:\n\t"                \
        : : : "$8", "$9");      \
        sceKernelIcacheClearAll(); \
}

Set the $pc register to a kernel memory address.

When the PSP's kernel library stubs are called, they expect to be accessed from the kernel's address space. Use this function to set $pc to the kernel address space, before calling a kernel library stub.
