* MIPS: Return after handling coprocessor 2 exceptionJesper Nilsson2010-07-05
| | | | | | | | | | | | | | Breaking here dropped us to the default code which always sends a SIGILL to the current process, no matter what the CU2 notifier says. [Ralf: Currently this only hurts on Cavium and possibly some out of tree platforms.] Signed-off-by: Jesper Nilsson <jesper@jni.nu> To: linux-mips@linux-mips.org To: linux-kernel@vger.kernel.org Patchwork: http://patchwork.linux-mips.org/patch/1391/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
* MIPS: BCM47xx: Add NVRAM support devicesWaldemar Brodkorb2010-07-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When trying to netboot a Linksys WRT54GS WLAN router, the bootup fails, because of following error message: ... [ 0.424000] b44: b44.c:v2.0 [ 0.424000] b44: Invalid MAC address found in EEPROM [ 0.432000] b44 ssb0:1: Problem fetching invariants of chip,aborting [ 0.436000] b44: probe of ssb0:1 failed with error -22 ... The router uses a CFE bootloader, but most of the needed environment variables for network card initialization, are not available from CFE via printenv and even though not via cfe_getenv(). The required environment variables are saved in a special partition in flash memory. The attached patch implement nvram_getenv and enables bootup via NFS root on my router. Most of the patch is extracted from the OpenWrt subversion repository and stripped down and cleaned up to just fix this issue. [Ralf: sorted out header file inclusions. Lots of unneded headers and such that should have been included.] Signed-off-by: Waldemar Brodkorb <wbx@openadk.org> Reviewed-by: Phil Sutter <phil@nwl.cc> To: linux-mips@linux-mips.org Cc: Hauke Mehrtens <hauke@hauke-m.de> Patchwork: http://patchwork.linux-mips.org/patch/1359/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

* MIPS: Tracing: Cleanup of address space checkingWu Zhangjin2010-07-05
| | | | | | | | | | | | | | | | | | | This patch adds an inline function in_module() to check which space the instruction pointer in, kernel space or module space. Note: This will not work when the kernel space and module space are the same. If they are the same, we need to modify scripts/recordmcount.pl, ftrace_make_nop/call() and the other related parts to ensure the enabling/disabling of the calling site to _mcount is right for both kernel and module. [Ralf: It also is still incorrect for some 64-bit kernels.] Signed-off-by: Wu Zhangjin <wuzhangjin@gmail.com> Cc: linux-mips <linux-mips@linux-mips.org> Cc: David Daney <david.s.daney@gmail.com> Patchwork: http://patchwork.linux-mips.org/patch/1232/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

* MIPS: Tracing: Reduce the overhead of dynamic Function TracerWu Zhangjin2010-07-05
| | | | | | | | | | | | | | | | With the help of uasm this patch encodes the instructions of the dynamic function tracer in ftrace_dyn_arch_init() when initializing it. As a result we can remove the dynamic encoding of instructions in ftrace_make_nop()/call(), ftrace_enable_ftrace_graph_caller() and remove the macro jump_insn_encode() and at last this reduce the overhead of dynamic Function Tracer. This also is cleaner.

| | | | | | | | | | | | | | | | As documented in the GCC 4.5 docs [1] -mmcount-ra-address uses register $12 to pass the stack offset of the return address to the _mcount function. On 64-bit kernels $12 is t0 but in 32-bit kernels it is t4 so we need to use $12 instead of t0 here to be correct for both kernel types.

| * | MIPS: Use GCC __builtin_prefetch() to implement prefetch().David Daney2010-05-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | GCC's __builtin_prefetch() was introduced a long time ago, all supported GCC versions have it. Lets do what the big boys up in linux/prefetch.h do, except we use '1' as the third parameter to provoke 'PREF 0,...' and 'PREF 1,...' instead of other prefetch hints. This allows for better code generation. In theory the existing embedded asm could be optimized, but the compiler has these builtins, so there is really no point.
