2012-11-15powerpc: Fix CONFIG_RELOCATABLE=y CONFIG_CRASH_DUMP=n buildAnton Blanchard1-1/+1
If we build a kernel with CONFIG_RELOCATABLE=y CONFIG_CRASH_DUMP=n, the kernel fails when we run at a non zero offset. It turns out we were incorrectly wrapping some of the relocatable kernel code with CONFIG_CRASH_DUMP.

2012-11-15powerpc/ptrace: Enable hardware breakpoint upon re-registeringAravinda Prasad1-0/+4
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 Mita1-54/+1
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.Prasad2-4/+90
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 Lawall1-3/+1
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 <[email protected]> Signed-off-by: Benjamin Herrenschmidt <[email protected]>
2012-11-15powerpc/pnv: Avoid bogus outputGavin Shan1-14/+11
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 Ellerman1-2/+8
It is possible to configure a kernel which has xmon enabled, but has no udbg backend to provide IO. This can make xmon rather confusing, as it produces no output, blocks for two seconds, and then returns. As a last resort we can instead try to printk(), which may deadlock or otherwise crash, but tries quite hard not to.

2012-11-15powerpc/xmon: Fiddle xmon_depth_to_print logic in xmon_show_stack()Michael Ellerman1-5/+3
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.

2012-11-15powerpc/xmon: Merge start.c into nonstdio.cMichael Ellerman4-26/+15
The routines in start.c are only ever called from nonstdio.c, so if we move them in there they can become static which is nice. I suspect the idea behind the separation was that start.c could be replaced in order to build xmon in userland. If anyone still cares about doing that we could handle that with an ifdef or two.

I'm reviving an old patch from 2009 that adds support for GXT4000P and GXT6500P adapter to the gxt4500 driver. See threads at http://marc.info/?l=linux-fbdev-devel&m=124345080216952&w=2 and https://lists.ozlabs.org/pipermail/linuxppc-dev/2009-June/072672.html for more details. This patch adds support for GXT4000P and GXT6500P cards found on some IBM pSeries machines. GXT4000P/6000P and GXT4500P/6500P couples are identical from software's point of view and are based on the same Raster Engine (RC1000), except for a different reference clock for the PLL. GXT6x00P models are equipped with an additional Geometry Engine (GT1000) but this driver doesn't use it.

This patch moves the notification chain for updates to the device tree from the powerpc/pseries code to the base OF code. This makes this functionality available to all architectures. Additionally the notification chain is updated to allow notifications for property add/remove/update. To make this work a pointer to a new struct (of_prop_reconfig) is passed to the routines in the notification chain. The of_prop_reconfig property contains a pointer to the node containing the property and a pointer to the property itself. In the case of property updates, the property pointer refers to the new property.
