tabort_syscall runs with RI=1, so a nested recoverable machine check will load the paca into r13 and overwrite what we loaded it with, because exceptions returning to privileged mode do not restore r13.

hmi.c functions are unused unless sibling_subcore_state is nonzero, and that in turn happens only if KVM is in use. So move the code to arch/powerpc/kvm/, putting it under CONFIG_KVM_BOOK3S_HV_POSSIBLE rather than CONFIG_PPC_BOOK3S_64. The sibling_subcore_state is also included in struct paca_struct only if KVM is supported by the kernel.

When booting from an OpenFirmware which supports it, we use the "ibm,client-architecture-support" firmware call to communicate our capabilities to firmware. The format of the structure we pass to firmware is specified in PAPR (Power Architecture Platform Requirements), or the public version LoPAPR (Linux on Power Architecture Platform Reference). Referring to table 244 in LoPAPR v1.1, option vector 5 contains a 4 byte field at bytes 17-20 for the "Platform Facilities Enable". This is followed by a 1 byte field at byte 21 for "Sub-Processor Represenation Level". Comparing to the code, there we have the Platform Facilities options (OV5_PFO_*) at byte 17, but we fail to pad that field out to its full width of 4 bytes. This means the OV5_SUB_PROCESSORS option is incorrectly placed at byte 18. Fix it by adding zero bytes for bytes 18, 19, 20, and comment the bytes to hopefully make it clearer in future. As far as I'm aware nothing actually consumes this value at this time, so the effect of this bug is nil in practice. It does mean we've been incorrectly setting bit 15 of the "Platform Facilities Enable" option for the past ~3 1/2 years, so we should avoid allocating that bit to anything else in future.

This patch leverages 'struct pci_host_bridge' from the PCI subsystem in order to free the pci_controller only after the last reference to its devices is dropped (avoiding an oops in pcibios_release_device() if the last reference is dropped after pcibios_free_controller()). The patch relies on pci_host_bridge.release_fn() (and .release_data), which is called automatically by the PCI subsystem when the root bus is released (i.e., the last reference is dropped). Those fields are set via pci_set_host_bridge_release() (e.g. in the platform-specific implementation of pcibios_root_bridge_prepare()). It introduces the 'pcibios_free_controller_deferred()' .release_fn() and it expects .release_data to hold a pointer to the pci_controller. The function implictly calls 'pcibios_free_controller()', so an user must *NOT* explicitly call it if using the new _deferred() callback. The functionality is enabled for pseries (although it isn't platform specific, and may be used by cxl). Details on not-so-elegant design choices: - Use 'pci_host_bridge.release_data' field as pointer to associated 'struct pci_controller' so *not* to 'pci_bus_to_host(bridge->bus)' in pcibios_free_controller_deferred(). That's because pci_remove_root_bus() sets 'host_bridge->bus = NULL' (so, if the last reference is released after pci_remove_root_bus() runs, which eventually reaches pcibios_free_controller_deferred(), that would hit a null pointer dereference). The cxl/vphb.c code calls pci_remove_root_bus(), and the cxl folks are interested in this fix.

When cxl removes a vPHB, it's possible that the pci_controller may be freed before all references to the devices on the vPHB have been released. This in turn causes an invalid memory access when the devices are eventually released, as pcibios_release_device() attempts to call the phb's release_device hook. In cxl_pci_vphb_remove(), remove the existing call to pcibios_free_controller(). Instead, use pcibios_free_controller_deferred() to free the pci_controller after all devices have been released. Export pci_set_host_bridge_release() so we can do this. Cc: stable@vger.kernel.org Signed-off-by: NAndrew Donnellan <andrew.donnellan@au1.ibm.com> Reviewed-by: NMatthew R.

This is an entirely new driver instead of yet another set of patches to sb_edac.c because: 1) Mapping from PCI devices to socket/memory controller is significantly different. Skylake scatters devices on a socket across a number of PCI buses. 2) There is an extra level of interleaving via the "mcroute" register that would be a little messy to squeeze into the old driver. 3) Validation is getting too expensive. Changes to sb_edac need to be checked against Sandy Bridge, Ivy Bridge, Haswell, Broadwell and Knights Landing.

When building gccgo in userspace, errno.h gets parsed and the go include file sysinfo.go is generated. Since EREFUSED is defined to the same value as ECONNREFUSED, and ECONNREFUSED is defined later on in errno.h, this leads to go complaining that EREFUSED isn't defined yet. Fix this trivial problem by moving the define of EREFUSED down after ECONNREFUSED in errno.h (and clean up the indenting while touching this line).

The kernel test robot reported a usercopy failure in the new hardened sanity checks, due to a page-crossing copy of the FPU state into the task structure. This happened because the kernel test robot was testing with SLOB, which doesn't actually do the required book-keeping for slab allocations, and as a result the hardening code didn't realize that the task struct allocation was one single allocation - and the sanity checks fail. Since SLOB doesn't even claim to support hardening (and you really shouldn't use it), the straightforward solution is to just make the usercopy hardening code depend on the allocator supporting it.
