powerpc: Add missing headers

2022-05-08T12:15:40Z

Don't inherit headers "by chances" from asm/prom.h, asm/mpc52xx.h, asm/pci.h etc... Include the needed headers, and remove asm/prom.h when it was needed exclusively for pulling necessary headers.

The replacement of with made the include of the latter in the middle of asm includes. Fix this up with the aid of the below script and manual adjustments here and there. import sys import re if len(sys.argv) is not 3: print "USAGE: %s

mm: introduce include/linux/pgtable.h

2020-06-09T16:39:13Z

The include/linux/pgtable.h is going to be the home of generic page table manipulation functions. Start with moving asm-generic/pgtable.h to include/linux/pgtable.h and make the latter include asm/pgtable.h.

powerpc/kernel: Change retrieval of pci_dn

2017-08-31T04:26:40Z

For a PCI device it's pci_dn can be retrieved from pdev->dev.archdata.firmware_data, PCI_DN(devnode), or parent's list. Thus, we should just use the existing function pci_get_pdn_by_devfn to get the pci_dn. Signed-off-by: Bryant G. Ly Reviewed-by: Sam Bobroff Signed-off-by: Michael Ellerman

powerpc: move find_and_init_phbs() to pSeries specific code

2015-04-11T10:49:09Z

Previously, find_and_init_phbs() was used in both PowerNV and pSeries setup. However, since RTAS support has been dropped from PowerNV, we can move it into a platform-specific file. Signed-off-by: Daniel Axtens Signed-off-by: Michael Ellerman

powerpc/eeh: Remove device_node dependency

2015-03-24T02:15:53Z

The patch removes struct eeh_dev::dn and the corresponding helper functions: eeh_dev_to_of_node() and of_node_to_eeh_dev(). Instead, eeh_dev_to_pdn() and pdn_to_eeh_dev() should be used to get the pdn, which might contain device_node on PowerNV platform. Signed-off-by: Gavin Shan Signed-off-by: Benjamin Herrenschmidt

powerpc: Remove superfluous bootmem includes

2014-11-09T22:59:26Z

Lots of places included bootmem.h even when not using bootmem. Signed-off-by: Anton Blanchard Tested-by: Emil Medve Signed-off-by: Michael Ellerman

powerpc/pseries: Drop config requests in EEH accessors

2014-10-15T00:27:19Z

The pSeires EEH config accessors rely on rtas_{read, write}_config() and the condition to check if the PE's config space is blocked should be moved to those 2 functions so that config requests from kernel, userland, EEH core can be dropped to avoid recursive EEH error if necessary.

powerpc/eeh: Rename flag EEH_PE_RESET to EEH_PE_CFG_BLOCKED

2014-10-15T00:27:18Z

The flag EEH_PE_RESET indicates blocking config space of the PE during reset time. We potentially need block PE's config space other than reset time. So it's reasonable to replace it with EEH_PE_CFG_BLOCKED to indicate its usage. There are no substantial code or logic changes in this patch. Signed-off-by: Gavin Shan Signed-off-by: Michael Ellerman
