2010-10-14powerpc/85xx: add cache-sram supportHarninder Rai
It adds cache-sram support in P1/P2 QorIQ platforms as under: * A small abstraction over powerpc's remote heap allocator * Exports mpc85xx_cache_sram_alloc()/free() APIs * Supports only one contiguous SRAM window * Drivers can do the following in Kconfig to use these APIs "select FSL_85XX_CACHE_SRAM if MPC85xx" * Required SRAM size and the offset where SRAM should be mapped must be provided at kernel command line as : cache-sram-size=<value> cache-sram-offset=<offset> Signed-off-by: Harninder Rai <harninder.rai@freescale.com> Signed-off-by: Vivek Mahajan <vivek.mahajan@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

2010-10-14oprofile/fsl emb: Don't set MSR[PMM] until after clearing the interrupt.Scott Wood
On an arch 2.06 hypervisor, a pending perfmon interrupt will be delivered to the hypervisor at any point the guest is running, regardless of MSR[EE]. In order to reflect this interrupt, the hypervisor has to mask the interrupt in PMGC0 -- and set MSRP[PMMP] to intercept futher guest accesses to the PMRs to detect when to unmask (and prevent the guest from unmasking early, or seeing inconsistent state). This has the side effect of ignoring any changes the guest makes to MSR[PMM], so wait until after the interrupt is clear, and thus the hypervisor should have cleared MSRP[PMMP], before setting MSR[PMM]. The counters wil not actually run until PMGC0[FAC] is cleared in pmc_start_ctrs(), so this will not reduce the effectiveness of PMM.

2010-10-14powerpc: Fix invalid page flags in create TLB CAM path for PTE_64BITPaul Gortmaker
There exists a four line chunk of code, which when configured for 64 bit address space, can incorrectly set certain page flags during the TLB creation. It turns out that this is code which isn't used, but might still serve a purpose. Since it isn't obvious why it exists or why it causes problems, the below description covers both in detail. For powerpc bootstrap, the physical memory (at most 768M), is mapped into the kernel space via the following path: MMU_init() | + adjust_total_lowmem() | + map_mem_in_cams() | + settlbcam(i, virt, phys, cam_sz, PAGE_KERNEL_X, 0); On settlbcam(), the kernel will create TLB entries according to the flag, PAGE_KERNEL_X. settlbcam() { ... TLBCAM[index].MAS1 = MAS1_VALID | MAS1_IPROT | MAS1_TSIZE(tsize) | MAS1_TID(pid); ^ These entries cannot be invalidated by the kernel since MAS1_IPROT is set on TLB property. ... if (flags & _PAGE_USER) { TLBCAM[index].MAS3 |= MAS3_UX | MAS3_UR; TLBCAM[index].MAS3 |= ((flags & _PAGE_RW) ? MAS3_UW : 0); } For classic BookE (flags & _PAGE_USER) is 'zero' so it's fine. But on boards like the the Freescale P4080, we want to support 36-bit physical address on it. So the following options may be set: CONFIG_FSL_BOOKE=y CONFIG_PTE_64BIT=y CONFIG_PHYS_64BIT=y As a result, boards like the P4080 will introduce PTE format as Book3E. As per the file: arch/powerpc/include/asm/pgtable-ppc32.h * #elif defined(CONFIG_FSL_BOOKE) && defined(CONFIG_PTE_64BIT) * #include <asm/pte-book3e.h> So PAGE_KERNEL_X is __pgprot(_PAGE_BASE | _PAGE_KERNEL_RWX) and the book3E version of _PAGE_KERNEL_RWX is defined with: (_PAGE_BAP_SW | _PAGE_BAP_SR | _PAGE_DIRTY | _PAGE_BAP_SX) Note the _PAGE_BAP_SR, which is also defined in the book3E _PAGE_USER: #define _PAGE_USER (_PAGE_BAP_UR | _PAGE_BAP_SR) /* Can be read */ So the possibility exists to wrongly assign the user MAS3_U<RWX> bits to kernel (PAGE_KERNEL_X) address space via the following code fragment: if (flags & _PAGE_USER) { TLBCAM[index].MAS3 |= MAS3_UX | MAS3_UR; TLBCAM[index].MAS3 |= ((flags & _PAGE_RW) ? MAS3_UW : 0); } Here is a dump of the TLB info from Simics with the above code present: ------ L2 TLB1 GT SSS UUU V I Row Logical Physical SS TLPID TID WIMGE XWR XWR F P V ----- ----------------- ------------------- -- ----- ----- ----- --- --- - - - 0 c0000000-cfffffff 000000000-00fffffff 00 0 0 M XWR XWR 0 1 1 1 d0000000-dfffffff 010000000-01fffffff 00 0 0 M XWR XWR 0 1 1 2 e0000000-efffffff 020000000-02fffffff 00 0 0 M XWR XWR 0 1 1 Actually this conditional code was used for two legacy functions: 1: support KGDB to set break point. KGDB already dropped this; now uses its core write to set break point. 2: io_block_mapping() to create TLB in segmentation size (not PAGE_SIZE) for device IO space. This use case is also removed from the latest PowerPC kernel. However, there may still be a use case for it in the future, like large user pages, so we can't remove it entirely. As an alternative, we match on all bits of _PAGE_USER instead of just any bits, so the case where just _PAGE_BAP_SR is set can't sneak through. With this done, the TLB appears without U having XWR as below: ------- L2 TLB1 GT SSS UUU V I Row Logical Physical SS TLPID TID WIMGE XWR XWR F P V ----- ----------------- ------------------- -- ----- ----- ----- --- --- - - - 0 c0000000-cfffffff 000000000-00fffffff 00 0 0 M XWR 0 1 1 1 d0000000-dfffffff 010000000-01fffffff 00 0 0 M XWR 0 1 1 2 e0000000-efffffff 020000000-02fffffff 00 0 0 M XWR 0 1 1 Signed-off-by: Tiejun Chen <tiejun.chen@windriver.com> Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

2010-10-13powerpc/pseries/xics: Use cpu_possible_mask rather than cpu_all_maskNishanth Aravamudan
Current firmware only allows us to send IRQs to the first processor or all processors. We currently check to see if the passed in mask is equal to the all_mask, but the firmware is only considering whether the request is for the equivalent of the possible_mask. Thus, we think the request is for some subset of CPUs and only assign IRQs to the first CPU (on systems without irqbalance running) as evidenced by /proc/interrupts. By using possible_mask instead, we account for this and proper interleaving of interrupts occurs.

2010-10-13powerpc/pseries: Partition migration in the kernelNathan Fontenot
Enable partition migration in the kernel. To do this a new sysfs file, /sys/kernel/mobility/migration, is created. In order to initiate a migration the stream id (generated by the HMC managing the system) is written to this file. After a migration occurs, and what is the majority of this code, the device tree needs to be updated for the new system the partition is running on. This is done via the ibm,update-nodes and ibm,update-properties rtas calls which return information regarding which nodes and properties of the device tree are to be added/removed/updated.

2010-10-05modules: Fix module_bug_list list corruption raceLinus Torvalds
With all the recent module loading cleanups, we've minimized the code that sits under module_mutex, fixing various deadlocks and making it possible to do most of the module loading in parallel. However, that whole conversion totally missed the rather obscure code that adds a new module to the list for BUG() handling. That code was doubly obscure because (a) the code itself lives in lib/bugs.c (for dubious reasons) and (b) it gets called from the architecture-specific "module_finalize()" rather than from generic code. Calling it from arch-specific code makes no sense what-so-ever to begin with, and is now actively wrong since that code isn't protected by the module loading lock any more. So this commit moves the "module_bug_{finalize,cleanup}()" calls away from the arch-specific code, and into the generic code - and in the process protects it with the module_mutex so that the list operations are now safe. Future fixups: - move the module list handling code into kernel/module.c where it belongs. - get rid of 'module_bug_list' and just use the regular list of modules (called 'modules' - imagine that) that we already create and maintain for other reasons.

The notifiers may be called at any time, so the notifier_block cannot be in init memory. Signed-off-by: David Daney <ddaney@caviumnetworks.com> To: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/1592/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2010-10-04MIPS: Calculate VMLINUZ_LOAD_ADDRESS based on the length of vmlinux.binShmulik Ladkani
Fix VMLINUZ_LOAD_ADDRESS calculation to be based on the length of vmlinux.bin, the actual uncompressed kernel binary. Previously it was based on the length of KBUILD_IMAGE (the unstripped ELF vmlinux), which is bigger than vmlinux.bin. As a result, vmlinuz was loaded into a memory address higher then actually needed - a problem for small memory platforms.

2010-10-04MIPS: Alchemy: Resolve prom section mismatchesManuel Lauss
The function prom_init_cmdline() references the variable __initdata arcs_cmdline. The function prom_get_ethernet_addr() references the variable __initdata arcs_cmdline. Annotate prom_init_cmdline() as __init, unexport and annotate prom_get_ethernet_addr() since it's no longer called from within driver code.
