powerpc/xmon: Add some more elements to the existing PACA dump list
This patch adds a set of new elements to the existing PACA dump list inside an xmon session which can be listed below improving the overall xmon debug support. With this patch, a typical xmon PACA dump looks something like this. paca for cpu 0x0 @ c00000000fdc0000: possible = yes present = yes online = yes lock_token = 0x8000 (0xa) paca_index = 0x0 (0x8) kernel_toc = 0xc000000001393200 (0x10) kernelbase = 0xc000000000000000 (0x18) kernel_msr = 0xb000000000001033 (0x20) emergency_sp = 0xc00000003fff0000 (0x28) mc_emergency_sp = 0xc00000003ffec000 (0x2e0) in_mce = 0x0 (0x2e8) hmi_event_available = 0x0 (0x2ea) data_offset = 0x1fe7b0000 (0x30) hw_cpu_id = 0x0 (0x38) cpu_start = 0x1 (0x3a) kexec_state = 0x0 (0x3b) slb_shadow[0]: = 0xc000000008000000 0x40016e7779000510 slb_shadow[1]: = 0xd000000008000001 0x400142add1000510 vmalloc_sllp = 0x510 (0x1b8) slb_cache_ptr = 0x4 (0x1ba) slb_cache[0]: = 0x000000000003f000 slb_cache[1]: = 0x0000000000000001 slb_cache[2]: = 0x0000000000000003 slb_cache[3]: = 0x0000000000001000 slb_cache[4]: = 0x0000000000001000 slb_cache[5]: = 0x0000000000000000 slb_cache[6]: = 0x0000000000000000 slb_cache[7]: = 0x0000000000000000 dscr_default = 0x0 (0x58) __current = 0xc000000001331e80 (0x290) kstack = 0xc000000001393e30 (0x298) stab_rr = 0x11 (0x2a0) saved_r1 = 0xc0000001fffef5e0 (0x2a8) trap_save = 0x0 (0x2b8) soft_enabled = 0x0 (0x2ba) irq_happened = 0x1 (0x2bb) io_sync = 0x0 (0x2bc) irq_work_pending = 0x0 (0x2bd) nap_state_lost = 0x0 (0x2be) sprg_vdso = 0x0 (0x2c0) tm_scratch = 0x8000000100009033 (0x2c8) core_idle_state_ptr = (null) (0x2d0) thread_idle_state = 0x0 (0x2d8) thread_mask = 0x0 (0x2d9) subcore_sibling_mask = 0x0 (0x2da) user_time = 0x0 (0x2f0) system_time = 0x0 (0x2f8) user_time_scaled = 0x0 (0x300) starttime = 0x3f462418b5cf4 (0x308) starttime_user = 0x3f4622a57092a (0x310) startspurr = 0xd62a5718 (0x318) utime_sspurr = 0x0 (0x320) stolen_time = 0x0 (0x328) Signed-off-by: Anshuman Khandual <khandual@linux.vnet.ibm.com> [mpe: Endian swap slb_shadow before display, minor formatting] Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
