Pull powerpc updates from Michael Ellerman: "Highlights include: - Support for the kexec_file_load() syscall, which is a prereq for secure and trusted boot. - Prevent kernel execution of userspace on P9 Radix (similar to SMEP/PXN). - Sort the exception tables at build time, to save time at boot, and store them as relative offsets to save space in the kernel image & memory. - Allow building the kernel with thin archives, which should allow us to build an allyesconfig once some other fixes land. - Build fixes to allow us to correctly rebuild when changing the kernel endian from big to little or vice versa. - Plumbing so that we can avoid doing a full mm TLB flush on P9 Radix. - Initial stack protector support (-fstack-protector). - Support for dumping the radix (aka. Linux) and hash page tables via debugfs. - Fix an oops in cxl coredump generation when cxl_get_fd() is used. - Freescale updates from Scott: "Highlights include 8xx hugepage support, qbman fixes/cleanup, device tree updates, and some misc cleanup." - Many and varied fixes and minor enhancements as always.

mm: use vmf->address instead of of vmf->virtual_address

2016-12-15T00:04:09Z

Every single user of vmf->virtual_address typed that entry to unsigned long before doing anything with it so the type of virtual_address does not really provide us any additional safety. Just use masked vmf->address which already has the appropriate type. Link: http://lkml.kernel.org/r/1479460644-25076-3-git-send-email-jack@suse.cz Signed-off-by: Jan Kara Acked-by: Kirill A.

powerpc: Make selects of IBM_EMAC_* depend on IBM_EMAC

2016-12-01T11:07:16Z

We have a bunch of Kconfig symbols which select various IBM_EMAC_* symbols. These all cause warnings when IBM_EMAC is not selected. eg. warning: (PPC_CELL_NATIVE && BLUESTONE && CANYONLANDS && GLACIER && EIGER && 440EPX && 440GRX && 440GX && 460SX && 405EX) selects IBM_EMAC_RGMII which has unmet direct dependencies (NETDEVICES && ETHERNET && NET_VENDOR_IBM) So make them all depend on IBM_EMAC being enabled first.

powerpc/cell: Drop select of MEMORY_HOTPLUG

2016-12-01T11:07:14Z

SPU_FS selects MEMORY_HOTPLUG, which is problematic because MEMORY_HOTPLUG is user selectable, meaning we can end up with a broken .config where MEMORY_HOTPLUG is enabled but its dependencies are not, leading to build breakages. The select of MEMORY_HOTPLUG for SPU_FS was added back in 2006, in commit 4da30d15b6d5 ("[POWERPC] spufs: fix memory hotplug dependency"). However we reworked the spufs code and removed the dependency on memory hotplug in 2007 in commit 78bde53e351b ("[POWERPC] spufs: remove need for struct page for SPEs"). So drop the select as it's no longer needed and causes problems. Signed-off-by: Michael Ellerman

powerpc: Change places using CONFIG_KEXEC to use CONFIG_KEXEC_CORE instead.

2016-11-30T12:15:11Z

Commit 2965faa5e03d ("kexec: split kexec_load syscall from kexec core code") introduced CONFIG_KEXEC_CORE so that CONFIG_KEXEC means whether the kexec_load system call should be compiled-in and CONFIG_KEXEC_FILE means whether the kexec_file_load system call should be compiled-in. These options can be set independently from each other. Since until now powerpc only supported kexec_load, CONFIG_KEXEC and CONFIG_KEXEC_CORE were synonyms. That is not the case anymore, so we need to make a distinction. Almost all places where CONFIG_KEXEC was being used should be using CONFIG_KEXEC_CORE instead, since kexec_file_load also needs that code compiled in.

fs: Replace CURRENT_TIME with current_time() for inode timestamps

2016-09-28T01:06:21Z

CURRENT_TIME macro is not appropriate for filesystems as it doesn't use the right granularity for filesystem timestamps. Use current_time() instead. CURRENT_TIME is also not y2038 safe. This is also in preparation for the patch that transitions vfs timestamps to use 64 bit time and hence make them y2038 safe. As part of the effort current_time() will be extended to do range checks. Hence, it is necessary for all file system timestamps to use current_time(). Also, current_time() will be transitioned along with vfs to be y2038 safe. Note that whenever a single call to current_time() is used to change timestamps in different inodes, it is because they share the same time granularity.

powerpc: Remove all usages of NO_IRQ

2016-09-20T10:57:12Z

NO_IRQ has been == 0 on powerpc for just over ten years (since commit 0ebfff1491ef ("[POWERPC] Add new interrupt mapping core and change platforms to use it")). It's also 0 on most other arches. Although it's fairly harmless, every now and then it causes confusion when a driver is built on powerpc and another arch which doesn't define NO_IRQ. There's at least 6 definitions of NO_IRQ in drivers/, at least some of which are to work around that problem. So we'd like to remove it. This is fairly trivial in the arch code, we just convert: if (irq == NO_IRQ) to if (!irq) if (irq != NO_IRQ) to if (irq) irq = NO_IRQ; to irq = 0; return NO_IRQ; to return 0; And a few other odd cases as well. At least for now we keep the #define NO_IRQ, because there is driver code that uses NO_IRQ and the fixes to remove those will go via other trees. Note we also change some occurrences in PPC sound drivers, drivers/ps3, and drivers/macintosh. Signed-off-by: Michael Ellerman
