Subrata Modak reported that building a CONFIG_RELOCATABLE kernel with CONFIG_ISERIES enabled gives the following warnings: WARNING: 4 bad relocations c00000000007216e R_PPC64_ADDR16_HIGHEST __ksymtab+0x00000000009dcec8 c000000000072172 R_PPC64_ADDR16_HIGHER __ksymtab+0x00000000009dcec8 c00000000007217a R_PPC64_ADDR16_HI __ksymtab+0x00000000009dcec8 c00000000007217e R_PPC64_ADDR16_LO __ksymtab+0x00000000009dcec8 The reason is that decrementer_iSeries_masked is using LOAD_REG_IMMEDIATE to get the address of a kernel symbol, which creates relocations that aren't handled by the kernel relocator code. Instead of reading the tb_ticks_per_jiffy variable, we can just set the decrementer to its maximum value (0x7fffffff) and that will work just as well. In fact timer_interrupt sets the decrementer to that value initially anyway, and we are sure to get into timer_interrupt once interrupts are reenabled because we store 1 to the decrementer interrupt flag in the lppaca (LPPACADECRINT(r12) here).
