| * powerpc: Fix vio_bus_probe oops on probe errorBrian King2008-08-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When CMO is enabled and booted on a non CMO system and the VIO device's probe function fails, an oops can result since vio_cmo_bus_remove is called when it should not. This fixes it by avoiding the vio_cmo_bus_remove call on platforms that don't implement CMO. cpu 0x0: Vector: 300 (Data Access) at [c00000000e13b3d0] pc: c000000000020d34: .vio_cmo_bus_remove+0xc0/0x1f4 lr: c000000000020ca4: .vio_cmo_bus_remove+0x30/0x1f4 sp: c00000000e13b650 msr: 8000000000009032 dar: 0 dsisr: 40000000 current = 0xc00000000e0566c0 paca = 0xc0000000006f9b80 pid = 2428, comm = modprobe enter ? for help [c00000000e13b6e0] c000000000021d94 .vio_bus_probe+0x2f8/0x33c [c00000000e13b7a0] c00000000029fc88 .driver_probe_device+0x13c/0x200 [c00000000e13b830] c00000000029fdac .__driver_attach+0x60/0xa4 [c00000000e13b8c0] c00000000029f050 .bus_for_each_dev+0x80/0xd8 [c00000000e13b980] c00000000029f9ec .driver_attach+0x28/0x40 [c00000000e13ba00] c00000000029f630 .bus_add_driver+0xd4/0x284 [c00000000e13baa0] c0000000002a01bc .driver_register+0xc4/0x198 [c00000000e13bb50] c00000000002168c .vio_register_driver+0x40/0x5c [c00000000e13bbe0] d0000000003b3f1c .ibmvfc_module_init+0x70/0x109c [ibmvfc] [c00000000e13bc70] c0000000000acf08 .sys_init_module+0x184c/0x1a10 [c00000000e13be30] c000000000008748 syscall_exit+0x0/0x40 Signed-off-by: Brian King <brking@linux.vnet.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
| * powerpc/ibmebus: Restore "name" sysfs attribute on ibmebus devicesJoachim Fenkes2008-08-201-12/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recent of_platform changes made of_bus_type_init() overwrite the bus type's .dev_attrs list, meaning that the "name" attribute that ibmebus devices previously had is no longer present. This is a user-visible regression which breaks the userspace eHCA support, since the eHCA userspace driver relies on the name attribute to check for valid adapters. This fixes it by providing the "name" attribute in the generic OF device code instead. Tested on POWER.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Based on an original patch from Christoph Hellwig <hch@lst.de>. Currently, there is a possible reference-after-free in the spusched code - contexts may be freed after we have released their state_mutex in spusched_tick and find_victim. This change takes a reference to the context before releasing the mutex, so that the context doesn't get destroyed. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
| | * powerpc/spufs: fix npc setting for NOSCHED contextsJeremy Kerr2008-08-131-7/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, spu_run ignores the npc argument for contexts created with SPU_CREATE_NOSCHED. While this is correct for isolated contexts, there's no need to enforce the npc restriction on non-isolated NOSCHED contexts. This means that NOSCHED contexts can only ever run with an entry point of 0x0. This change to spu_run_init allows setting of the npc (and, while we're at it, the privcntl) for non-isolated NOSCHED contexts. This allows us to run NOSCHED contexts from any entry point.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the firmware page size used for collaborative memory overcommit is 4k, but the kernel is using 64k pages, the page loaning is currently broken as it only marks the first 4k page of each 64k page as loaned.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The intent of "flush_tlbs" is to invalidate all TLB entries by doing a TLB invalidate instruction for all pages in the address range 0 to 0x00400000. A loop counter is set up at the high value and decremented by page size. However, the loop is only done once as the sense of the conditional branch at the loop end does not match the setup/decrement. This fixes it to do the whole range by correcting the branch condition. Signed-off-by: Rocky Craig <rocky.craig@hp.com> Signed-off-by: Paul Mackerras <paulus@samba.org>

|/ / | | | | | | | | | | | | | | | | | | | | | | | | When we fork, init_new_context() improperly resets the vdso_base of the new context to 0. That means that the new process loses access to the vdso for signal trampolines. The initialization should be unnecessary anyway as the context on a fresh mm should be 0 in the first place and binfmt_elf will initialize that value for a newly loaded process.

It's also used by early boot ioremap (before mem_init_done). However, the way ioremap uses it is incorrect as it passes it the protection flags in the "linux PTE" form while htab_bolt_mapping() expects them in the hash table format. This is made more confusing by the fact that some of those flags are actually in the same position in both cases. This fixes it all by making htab_bolt_mapping() take normal linux protection flags instead, and use a little helper to convert them to htab flags. Callers can now use the usual PAGE_* definitions safely.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we have an ISA memory hole (ie, a PCI window that allows us to generate PCI memory cycles at low PCI address) mixed with other resources using a different CPU <=> PCI mapping, we must not keep the ISA hole in the bridge resource list. If we do, things might start trying to allocate device resources in there and will get the PCI addresses wrong. This fixes it by arranging to remove the ISA memory hole resource in this case. This fixes various cases of PCMCIA breakage on PowerBooks using the MPC106 "grackle" bridge.

These are copied back to user space with the assumption that every value has been set by the rtas call, which turns out to be not always true. Thus userspace can see random values and think the call failed when in fact it succeeded, but for some reason didn't set one of the return values. This fixes the problem by zeroing out the return value fields of the rtas args struct before processing the rtas call.

| * powerpc: Allow non-hcall return values for lparcfg writesNathan Fontenot2008-07-301-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The code to handle writes to /proc/ppc64/lparcfg incorrectly assumes that the return code from the helper routines to update processor or memory entitlement return a hcall return value. It then assumes any non-hcall return value is bad and sets the return code for the write to be -EIO. The update_[mp]pp routines can return values other than a hcall return value. This patch removes the automatic setting of any return code that is not an hcall return value from these routines to -EIO.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | add simple-bus compatible property to soc nodes for 83xx/85xx platforms that were missing them. Add same to platform probe code. This fixes SoC device drivers (such as talitos) to succeed in matching devices present in the soc node. also update mpc836x_rdk dts to new SEC bindings (overlooked in commit 3fd4473: powerpc/fsl: update crypto node definition and device tree instances).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The CPM2 BRG setup functions cpm_setbrg and cpm2_fastbrg don't support external clocks. This patch adds a new exported __cpm2_setbrg function that takes the clock rate and clock source as extra parameters, and moves cpm_setbrg and cpm2_fastbrg to include/asm-powerpc/cpm2.h where they become inline wrappers around __cpm2_setbrg.

| | * powerpc: rtc_cmos_setup: assign interrupts only if there is i8259 PICAnton Vorontsov2008-07-281-6/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | i8259 PIC is disabled on MPC8610HPCD boards, thus currently rtc-cmos driver fails to probe. To fix the issue, we lookup the device tree for "chrp,iic" and "pnpPNP,000" compatible devices, and if not found we do not assign RTC IRQ and assuming that i8259 was disabled. Though this patch fixes RTC on some boards (and surely should not break any other), the whole approach is still broken. We can't easily fix this though, because old device trees do not specify i8259 interrupts for the cmos rtc node.
