* 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.

* MIPS: Tracing: Fix argument passing of the 32bit support with gcc 4.5Wu Zhangjin2010-07-05
| | | | | | | | | | | | | | | | 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.

After it was pointed out the the range on io_apics was inclusive I changed my global variable to match. That was a big mistake. Inclusive semantics without a range start cannot describe the case when no gsi's are allocated. Describing the case where no gsi's are allocated is important in sfi.c and mpparse.c so that we can assign gsi numbers instead of blindly copying the gsi assignments the BIOS has done as we do in the acpi case. To keep from getting the global variable confused with the gsi range end rename it gsi_top. To allow describing the case where no gsi's are allocated have gsi_top be one place the highest gsi number seen in the system.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to my schematics, on Lite5200 board ethernet phy uses address 0 (all ADDR lines are pulled down). With this change I can talk to onboard phy (LXT971) and correctly use autonegotiation.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When going to standby mode mpc code maps the whole soc5200 node to access warious MBAR registers. However as of_iomap uses 'reg' property of device node, only small part of MBAR is getting mapped. Thus pm code gets oops when trying to access high parts of MBAR. As a way to overcome this, make mpc52xx_pm_prepare() explicitly map whole MBAR (0xc0000).

It avoids enabling the IDE interface on the Avanti family, since none has IDE. It enables the Enhanced Parallel Port v1.9 feature. Signed-off-by: Morten H.

FLASH: kernel bug...flash list header addr above 4GB The code in question has a comment that the flash list should be in the kernel data and therefore under 4GB: /* NOTE: the "first" block list is a global var with no data * blocks in the kernel data segment. We do this because * we want to ensure this block_list addr is under 4GB. */ Unfortunately the Kconfig option is marked tristate which means the variable may not be in the kernel data and could be above 4GB. Instead of relying on the data segment being below 4GB, use the static data buffer allocated by the kernel for use by rtas. Since we don't use the header struct directly anymore, convert it to a simple pointer.
