2013-01-16powerpc: Add missing NULL terminator to avoid boot panic on PPC40xGabor Juhos
commit e6449c9b2d90c1bd9a5985bf05ddebfd1631cd6b upstream. The missing NULL terminator can cause a panic on PPC405 boards during boot: Linux/PowerPC load: console=ttyS0,115200 root=/dev/mtdblock1 rootfstype=squashfs,jffs2 noinitrd init=/etc/preinit Finalizing device tree... flat tree at 0x6a5160 bootconsole [udbg0] enabled Page fault in user mode with in_atomic() = 1 mm = (null) NIP = c0275f50 MSR = fffffffe Oops: Weird page fault, sig: 11 [#1] PowerPC 40x Platform Modules linked in: NIP: c0275f50 LR: c0275f60 CTR: c0280000 REGS: c0275eb0 TRAP: 636f7265 Not tainted (3.7.1) MSR: fffffffe <VEC,VSX,EE,PR,FP,ME,SE,BE,IR,DR,PMM,RI> CR: c06a6190 XER: 00000001 TASK = c02662a8[0] 'swapper' THREAD: c0274000 GPR00: c0275ec0 c000c658 c027c4bf 00000000 c0275ee0 c000a0ec c020a1a8 c020a1f0 GPR08: c020f631 c020f404 c025f078 c025f080 c0275f10 Call Trace: ---[ end trace 31fd0ba7d8756001 ]--- Kernel panic - not syncing: Attempted to kill the idle task! The panic happens since commit 9597abe00c1bab2aedce6b49866bf6d1e81c9eed (sections: fix section conflicts in arch/powerpc), however the root cause of this is that the NULL terminator were not added in commit a4f740cf33f7f6c164bbde3c0cdbcc77b0c4997c (of/flattree: Add of_flat_dt_match() helper function).

2012-10-17powerpc/eeh: Lock module while handling EEH eventGavin Shan
commit feadf7c0a1a7c08c74bebb4a13b755f8c40e3bbc upstream. The EEH core is talking with the PCI device driver to determine the action (purely reset, or PCI device removal). During the period, the driver might be unloaded and in turn causes kernel crash as follows: EEH: Detected PCI bus error on PHB#4-PE#10000 EEH: This PCI device has failed 3 times in the last hour lpfc 0004:01:00.0: 0:2710 PCI channel disable preparing for reset Unable to handle kernel paging request for data at address 0x00000490 Faulting instruction address: 0xd00000000e682c90 cpu 0x1: Vector: 300 (Data Access) at [c000000fc75ffa20] pc: d00000000e682c90: .lpfc_io_error_detected+0x30/0x240 [lpfc] lr: d00000000e682c8c: .lpfc_io_error_detected+0x2c/0x240 [lpfc] sp: c000000fc75ffca0 msr: 8000000000009032 dar: 490 dsisr: 40000000 current = 0xc000000fc79b88b0 paca = 0xc00000000edb0380 softe: 0 irq_happened: 0x00 pid = 3386, comm = eehd enter ? for help [c000000fc75ffca0] c000000fc75ffd30 (unreliable) [c000000fc75ffd30] c00000000004fd3c .eeh_report_error+0x7c/0xf0 [c000000fc75ffdc0] c00000000004ee00 .eeh_pe_dev_traverse+0xa0/0x180 [c000000fc75ffe70] c00000000004ffd8 .eeh_handle_event+0x68/0x300 [c000000fc75fff00] c0000000000503a0 .eeh_event_handler+0x130/0x1a0 [c000000fc75fff90] c000000000020138 .kernel_thread+0x54/0x70 1:mon> The patch increases the reference of the corresponding driver modules while EEH core does the negotiation with PCI device driver so that the corresponding driver modules can't be unloaded during the period and we're safe to refer the callbacks.

2012-01-12powerpc: Fix unpaired probe_hcall_entry and probe_hcall_exitLi Zhong
commit e4f387d8db3ba3c2dae4d8bdfe7bb5f4fe1bcb0d upstream. Unpaired calling of probe_hcall_entry and probe_hcall_exit might happen as following, which could cause incorrect preempt count. __trace_hcall_entry => trace_hcall_entry -> probe_hcall_entry => get_cpu_var => preempt_disable __trace_hcall_exit => trace_hcall_exit -> probe_hcall_exit => put_cpu_var => preempt_enable where: A => B and A -> B means A calls B, but => means A will call B through function name, and B will definitely be called. -> means A will call B through function pointer, so B might not be called if the function pointer is not set. So error happens when only one of probe_hcall_entry and probe_hcall_exit get called during a hcall. This patch tries to move the preempt count operations from probe_hcall_entry and probe_hcall_exit to its callers. Reported-by: Paul E.

The driver for the Freescale P3060 QDS got added by commit 96cc017c5b ("[...] Add support for P3060QDS board"). Its Kconfig entry selects MPC8xxx_GPIO. But at the time that driver got added MPC8xxx_GPIO was already renamed to GPIO_MPC8XXX, by commit c68308dd50c ("gpio: move mpc8xxx/512x gpio driver to drivers/gpio"). So make this driver select GPIO_MPC8XXX. Signed-off-by: Paul Bolle <pebolle@tiscali.nl> Acked-by: Wolfram Sang <w.sang@pengutronix.de> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

2011-11-16powerpc/ps3: Fix lost SMP IPIsGeoff Levand
Fixes the PS3 bootup hang introduced in 3.0-rc1 by: commit 317f394160e9beb97d19a84c39b7e5eb3d7815a sched: Move the second half of ttwu() to the remote cpu Move the PS3's LV1 EOI call lv1_end_of_interrupt_ext() from ps3_chip_eoi() to ps3_get_irq() for IPI messages. If lv1_send_event_locally() is called between a previous call to lv1_send_event_locally() and the coresponding call to lv1_end_of_interrupt_ext() the second event will not be delivered to the target cpu. The PS3's SMP IPIs are implemented using lv1_send_event_locally(), so if two IPI messages of the same type are sent to the same target in a relatively short period of time the second IPI event can become lost when lv1_end_of_interrupt_ext() is called from ps3_chip_eoi().

2011-10-31powerpc: add export.h to files making use of EXPORT_SYMBOLPaul Gortmaker
With module.h being implicitly everywhere via device.h, the absence of explicitly including something for EXPORT_SYMBOL went unnoticed. Since we are heading to fix things up and clean module.h from the device.h file, we need to explicitly include these files now. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>

2011-10-13powerpc/85xx: Setup secondary cores PIR with hard SMP idKumar Gala
Normally logical and hard cpu ID are the same, however in same cases like on the P3060 they may differ. Where the logical is 0..5, the hard id goes 0,1,4..7. This can causes issues for places we utilize PIR to index into array like in debug exception handlers for finding the exception stack. Move to setting up PIR with hard_smp_processor_id fixes the issue. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2011-10-11powerpc/85xx: clean up FPGA device tree nodes for Freecsale QorIQ boardsTimur Tabi
Standarize and document the FPGA nodes used on Freescale QorIQ reference boards. There are different kinds of FPGAs used on the boards, but only two are currently standard: "pixis", "ngpixis", and "qixis". Although there are minor differences among the boards that have one kind of FPGA, most of the functionality is the same, so it makes sense to create common compatibility strings. We also need to update the P1022DS platform file, because the compatible string for its PIXIS node has changed. This means that older kernels are not compatible with newer device trees. This is not a real problem, however, since that particular function doesn't work anyway. When the DIU is active, the PIXIS is in "indirect mode", and so cannot be accessed as a memory-mapped device.

There's only p2041rdb board for official release, but the p2041 silicon on the board can be converted to p2040 silicon without XAUI and L2 cache function, then the board becomes p2040rdb board. so we use the file name p2041_rdb.c to handle P2040RDB board and P2041RDB board which is also consistent with the board name under U-Boot. During the rename we make few other minor changes to the device tree: * Move USB phy setting into p2041si.dtsi as its SoC not board defined * Convert PCI clock-frequency to decimal to be more readable Signed-off-by: Mingkai Hu <Mingkai.hu@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

Therefore, there's no point in keeping a global variable that indicates which mode we're supposed to use.

2011-09-29powerpc: Fix device-tree matching for Apple U4 bridgeBenjamin Herrenschmidt
Apple Quad G5 has some oddity in it's device-tree which causes the new generic matching code to fail to relate nodes for PCI-E devices below U4 with their respective struct pci_dev. This breaks graphics on those machines among others. This fixes it using a quirk which copies the node pointer from the host bridge for the root complex, which makes the generic code work for the children afterward.
