* powerpc/cell: Fix cell iommu after it_page_shift changesMichael Ellerman2015-04-10
| | | | | | | | | | | | The patch to add it_page_shift incorrectly changed the increment of uaddr to use it_page_shift, rather then (1 << it_page_shift). This broke booting on at least some Cell blades, as the iommu was basically non-functional.

* powerpc/cell: Fix crash in iic_setup_cpu() after per_cpu changesMichael Ellerman2015-04-10
| | | | | | | | | | | | | The conversion from __get_cpu_var() to this_cpu_ptr() in iic_setup_cpu() is wrong. It causes an oops at boot. We need the per-cpu address of struct cpu_iic, not cpu_iic.regs->prio. Sparse noticed this, because we pass a non-iomem pointer to out_be64(), but we obviously don't check the sparse results often enough.

* powerpc: Reword the "returning from prom_init" messageMichael Ellerman2015-04-10
| | | | | | | | | | | | | | | | | | | | | | | | | We get way too many bug reports that say "the kernel is hung in prom_init", which stems from the fact that the last piece of output people see is "returning from prom_init". The kernel is almost never hung in prom_init(), it's just that it's crashed somewhere after prom_init() but prior to the console coming up. The existing message should give a clue to that, ie. "returning from" indicates that prom_init() has finished, but it doesn't seem to work. Let's try something different. This prints: Quiescing Open Firmware ... Booting Linux via __start() ... Which hopefully makes it clear that prom_init() is not the problem, and although __start() probably isn't either, it's at least the right place to begin looking.

* powerpc: Replace mem_init_done with slab_is_available()Michael Ellerman2015-04-10
| | | | | | | | | | | | | We have a powerpc specific global called mem_init_done which is "set on boot once kmalloc can be called". But that's not *quite* true. We set it at the bottom of mem_init(), and rely on the fact that mm_init() calls kmem_cache_init() immediately after that, and nothing is running in parallel. So replace it with the generic and 100% correct slab_is_available(). Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>

* powerpc/mm: Change setbat() to take a pgprot_t rather than flagsMichael Ellerman2015-04-07
| | | | | | | | | The callers of setbat() are actually passing a pgprot_t for the flags parameter. This doesn't matter unless STRICT_MM_TYPECHECKS is enabled.

| | | | | | | | | | | | | | | | | | | | | | | | The powerpc specific st_le*() and ld_le*() functions in arch/powerpc/asm/swab.h no longer have any users. They are also misleadingly named, since they always byteswap, even on a little-endian host. This patch removes them.

| * powerpc: Cleanup KVM emulated load/store endian handlingDavid Gibson2015-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sometimes the KVM code on powerpc needs to emulate load or store instructions from the guest, which can include both normal and byte reversed forms. We currently (AFAICT) handle this correctly, but some variable names are very misleading. In particular we use "is_bigendian" in several places to actually mean "is the IO the same endian as the host", but we now support little-endian powerpc hosts. This also ties into the misleadingly named ld_le*() and st_le*() functions, which in fact always byteswap, even on an LE host. This patch cleans this up by renaming to more accurate "host_swabbed", and uses the generic swab*() functions instead of the powerpc specific and misleadingly named ld_le*() and st_le*() functions.

| * powerpc: Remove arch specific byteswappers from the MXC MMC driverDavid Gibson2015-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the MXC MMUC driver is used on a Freescale MPC512x machine, it contains some additional byteswapping code (I'm assuming this is a workaround for a hardware defect). This uses the ppc specific st_le32() function, but there's no reason not to use the generic swab32() function instead. gcc is capable of generating the efficient ppc byte-reversing load/store instructions without the arch-specific helper. This patch, therefore, switches to the generic byteswap routine.

| * powerpc: Move Power Macintosh drivers to generic byteswappersDavid Gibson2015-03-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ppc has special instruction forms to efficiently load and store values in non-native endianness. These can be accessed via the arch-specific {ld,st}_le{16,32}() inlines in arch/powerpc/include/asm/swab.h. However, gcc is perfectly capable of generating the byte-reversing load/store instructions when using the normal, generic cpu_to_le*() and le*_to_cpu() functions eaning the arch-specific functions don't have much point. Worse the "le" in the names of the arch specific functions is now misleading, because they always generate byte-reversing forms, but some ppc machines can now run a little-endian kernel. To start getting rid of the arch-specific forms, this patch removes them from all the old Power Macintosh drivers, replacing them with the generic byteswappers.

| * | powerpc/powernv: Don't map M64 segments using M32DTGavin Shan2015-03-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If M64 has been supported, the prefetchable 64-bits memory resources shouldn't be mapped to the corresponding PE# via M32DT. Unfortunately, we're doing that in pnv_ioda_setup_pe_seg() wrongly. The issue was introduced by commit 262af55 ("powerpc/powernv: Enable M64 aperatus for PHB3").

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The function eeh_add_parent_pe() is used to create a PE or add one edev to its parent PE. Current code checks if PE#0 is valid for the later case. Actually, we should validate PE#0 for both cases when EEH core regards PE#0 as invalid one (without flag EEH_VALID_PE_ZERO). Otherwise, not all EEH devices can be added to its parent PE#0 for EEH on P7IOC. The patch fixes the issue by validating PE#0 for the two cases. So far, we don't have PE#0 for EEH on P7IOC, but it will show up when we enable M64 for P7IOC. The patch also makes the error message more meaningful.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Originally, EEH core probes on device_node or pci_dev to populate EEH devices and PEs, which conflicts with the fact: SRIOV VFs are usually enabled and created by PF's driver and they don't have the corresponding device_nodes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Originally, EEH probes on device_node or pci_dev and populates the corresponding eeh_dev. In the subsequent patches, EEH will probes on pci_dn and populates the corresponding eeh_dev. So we have to cache some information in pci_dn, either from device_node or SRIOV PF's enablement platform hook, to populate the eeh_dev properly. The motivation to probe pci_dn, instead of device node or pci_dev, to populate eeh_dev is SRIOV VFs are dynamically created and we don't have the corresponding device nodes for them.

Unfortunately, SRIOV VFs won't have the corresponding device nodes. pci_dn will be used in replacement with device node for SRIOV VFs. So we have to use pci_dn in PCI config accessors. The patch refactors pci_dn in following aspects to make it ready to be used in PCI config accessors as we do in subsequent patch: * pci_dn is organized as a hierarchy tree. PCI device's pci_dn is put to the child list of pci_dn of its upstream bridge or PHB. VF's pci_dn will be put to the child list of pci_dn of PF's bridge. * For one particular PCI device (VF or not), its pci_dn can be found from pdev->dev.archdata.pci_data, PCI_DN(devnode), or parent's list. The fast path (fetching pci_dn through PCI device instance) is populated during early fixup time.

| * | powerpc: book3e_64: fix the align size for paca_structKevin Hao2015-03-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All the cache line size of the current book3e 64bit SoCs are 64 bytes. So we should use this size to align the member of paca_struct. This only change the paca_struct's members which are private to book3e CPUs, and should not have any effect to book3s ones. With this, we save 192 bytes. Also change it to __aligned(size) since it is preferred over __attribute__((aligned(size))). Before: /* size: 1920, cachelines: 30, members: 46 */ /* sum members: 1667, holes: 6, sum holes: 141 */ /* padding: 112 */ After: /* size: 1728, cachelines: 27, members: 46 */ /* sum members: 1667, holes: 4, sum holes: 13 */ /* padding: 48 */ Signed-off-by: Kevin Hao <haokexin@gmail.com> Signed-off-by: Scott Wood <scottwood@freescale.com>
