2012-11-15powerpc: Move initial mfspr LPCR out of __init_LPCRMichael Neuling

2012-11-15powerpc: Add relocation on exception vector handlersMichael Neuling
POWER8/v2.07 allows exceptions to be taken with the MMU still on. A new set of exception vectors is added at 0xc000_0000_0000_4xxx. When the HW takes us here, MSR IR/DR will be set already and we no longer need a costly RFID to turn the MMU back on again. The original 0x0 based exception vectors remain for when the HW can't leave the MMU on. Examples of this are when we can't trust the current MMU mappings, like when we are changing from guest to hypervisor (HV 0 -> 1) or when the MMU was off already. In these cases the HW will take us to the original 0x0 based exception vectors with the MMU off as before. This uses the new macros added previously too implement these new execption vectors at 0xc000_0000_0000_4xxx. We exit these exception vectors using mflr/blr (rather than mtspr SSR0/RFID), since we don't need the costly MMU switch anymore. This moves the __end_interrupts marker down past these new 0x4000 vectors since they will need to be copied down to 0x0 when the kernel is not at 0x0.

2012-11-15powerpc: Add new macros needed for relocation on exceptionsMichael Neuling
POWER8/v2.07 allows exceptions to be taken with the MMU still on. A new set of exception vectors is added at 0xc000_0000_0000_4xxx. When the HW takes us here, MSR IR/DR will be set already and we no longer need a costly RFID to turn the MMU back on again. The original 0x0 based exception vectors remain for when the HW can't leave the MMU on. Examples of this are when we can't trust the current the MMU mappings, like when we are changing from guest to hypervisor (HV 0 -> 1) or when the MMU was off already. In these cases the HW will take us to the original 0x0 based exception vectors with the MMU off as before. The below macros are copies of the macros used at the 0x0 offset but modified to handle the MMU being on. In these macros we use the link register to jump to the secondary handlers rather than using RFID (RFID was also use to turn on the MMU).

2012-11-15powerpc/ptrace: Enable hardware breakpoint upon re-registeringAravinda Prasad
On powerpc, ptrace will disable hardware breakpoint request once the breakpoint is hit. It is the responsibility of the caller to set it again. However, when the caller sets the hardware breakpoint again using ptrace(PTRACE_SET_DEBUGREG, child_pid, 0, addr), the hardware breakpoint is not enabled. While gdb's approach is to unregister and re-register the hardware breakpoint every time the breakpoint is hit - which is working fine, this could affect other programs trying to re-register hardware breakpoint without unregistering. This patch enables hardware breakpoint if the caller is re-registering.

2012-11-15powerpc: Use asm-generic/bitops/le.hAkinobu Mita
The only difference between powerpc and asm-generic le-bitops is test_bit_le(). Usually all bitops require a long aligned bitmap. But powerpc test_bit_le() can take an unaligned address. There is no special callsite of test_bit_le() that needs unaligned access in powerpc as far as I can see. So convert to use asm-generic/bitops/le.h for powerpc.

2012-11-15powerpc/hw-breakpoint: Use generic hw-breakpoint interfaces for new PPC ↵K.Prasad
ptrace flags PPC_PTRACE_GETHWDBGINFO, PPC_PTRACE_SETHWDEBUG and PPC_PTRACE_DELHWDEBUG are PowerPC specific ptrace flags that use the watchpoint register. While they are targeted primarily towards BookE users, user-space applications such as GDB have started using them for BookS too. This patch enables the use of generic hardware breakpoint interfaces for these new flags. Apart from the usual benefits of using generic hw-breakpoint interfaces, these changes allow debuggers (such as GDB) to use a common set of ptrace flags for their watchpoint needs and allow more precise breakpoint specification (length of the variable can be specified).

2012-11-15powerpc/rtas_flash: Eliminate possible double freeJulia Lawall
The function initialize_flash_pde_data is only called four times. All four calls are in the function rtas_flash_init, and on the failure of any of the calls, remove_flash_pde is called on the third argument of each of the calls. There is thus no need for initialize_flash_pde_data to call remove_flash_pde on the same argument. remove_flash_pde kfrees the data field of its argument, and does not clear that field, so this amounts ot a possible double free. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r@ identifier f,free,a; parameter list[n] ps; type T; expression e; @@ f(ps,T a,...) { ... when any when != a = e if(...) { ... free(a); ... return ...; } ... when any } @@ identifier r.f,r.free; expression x,a; expression list[r.n] xs; @@ * x = f(xs,a,...); if (...) { ... free(a); ... return ...; } // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2012-11-15powerpc/pnv: Avoid bogus outputGavin Shan
There're couples of functions defined to print debugging messages during initializing P7IOC. However, we got bogus output from those functions like pe_info(). The problem here is that the message level (the first parameter to printk()) isn't printable and that caused the bogus output. The patch fixes the issue by merging __pe_printk() to the macro define_pe_printk_level() so that we can pass the message level directly to printk().

2012-11-15powerpc/xmon: Fallback to printk() in xmon_printf() if udbg is not setupMichael Ellerman
It is possible to configure a kernel which has xmon enabled, but has no udbg backend to provide IO.

Currently xmon_depth_to_print is static and global, but it's only ever used in xmon_show_stack(). At least with a modern compiler it's inlined, so there's no point in it being static, we could #define it but it's only used in one place. By reworking the logic we can drop count and just decrement the max value as a loop counter. Also switch to a while loop so we actually print no more than 64 frames as you'd expect based on the variable name.
