Rationales from Eric: So I just looked a little deeper and it appears architectures that do not support atomic64_t are broken. The generic atomic64 support came in 2009 to support the perf subsystem with the expectation that all architectures would implement atomic64 support. Furthermore upon inspection of the kernel atomic64_t is used in a fair number of places beyond the performance counters: block/blk-cgroup.c drivers/acpi/apei/ drivers/block/rbd.c drivers/crypto/nx/nx.h drivers/gpu/drm/radeon/radeon.h drivers/infiniband/hw/ipath/ drivers/infiniband/hw/qib/ drivers/staging/octeon/ fs/xfs/ include/linux/perf_event.h include/net/netfilter/nf_conntrack_acct.h kernel/events/ kernel/trace/ net/mac80211/key.h net/rds/ The block control group, infiniband, xfs, crypto, 802.11, netfilter. Nothing quite so fundamental as fs/namespace.c but definitely in multiplatform-code that should work, and is already broken on those architecutres. Looking at the implementation of atomic64_add_return in lib/atomic64.c the code looks as efficient as these kinds of things get. Which leads me to the conclusion that we need atomic64 support on all architectures. Signed-off-by: NFengguang Wu <fengguang.wu@intel.com> Cc: "Eric W.

The inb/outb macros for CRIS are broken from a number of points of view, missing () around parameters and they have an unprotected if statement in them. This was breaking the compile of IPMI on CRIS and thus I was being annoyed by build regressions, so I fixed them. Plus I don't think they would have worked at all, since the data values were missing "&" and the outsl had a "3" instead of a "4" for the size. From what I can tell, this stuff is not used at all, so this can't be any more broken than it was before, anyway.

With CONFIG_PARAVIRT=y and CONFIG_TRANSPARENT_HUGEPAGE=n, the build breaks because set_pmd_at() is undeclared: mm/memory.c: In function 'do_pmd_numa_page': mm/memory.c:3520: error: implicit declaration of function 'set_pmd_at' mm/mprotect.c: In function 'change_pmd_protnuma': mm/mprotect.c:120: error: implicit declaration of function 'set_pmd_at' This is because paravirt defines set_pmd_at() only when CONFIG_TRANSPARENT_HUGEPAGE=y and such a restriction is unneeded. The fix is to define it for all CONFIG_PARAVIRT configurations. Signed-off-by: NDavid Rientjes <rientjes@google.com> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

Git commit 30106c17 ("x86, hotplug: Support functions for CPU0 online/offline") alters what the call to smp_store_cpu_info() does. For BSP we should use the smp_store_boot_cpu_info() and for secondary CPU's the old variant of smp_store_cpu_info() should be used. This fixes the regression introduced by said commit.

This function is used by sparc, powerpc tile and arm64 for compat support. The patch adds a generic implementation with a wrapper for PowerPC to do the u32->int sign extension. The reason for a single patch covering powerpc, tile, sparc and arm64 is to keep it bisectable, otherwise kernel building may fail with mismatched function declarations.

Currently the __define_initcall() macro takes three arguments, fn, id and level. The level argument is exactly the same as the id argument but wrapped in quotes. To overcome this need to specify three arguments to the __define_initcall macro, where one argument is the stringification of another, we can just use the stringification macro instead.

This reverts commit 53b87cf0. It causes odd bootup problems on x86-64. Markus Trippelsdorf gets a repeatable oops, and I see a non-repeatable oops (or constant stream of messages that scroll off too quickly to read) that seems to go away with this commit reverted. So we don't know exactly what is wrong with the commit, but it's definitely problematic, and worth reverting sooner rather than later.

Use the newer idioms for setting PTRACE_O_xxx and PT_TRACE_xxx flags. Only set/clear tile-specific flags if the generic routine returns success, since otherwise we want to avoid setting any flags at all. Atomically update the ptrace flags with the new values. Eliminate the PT_TRACE_MASK_TILE bitmask and just shift PTRACE_O_MASK_TILE. Add a BUILD_BUG_ON to avoid overlapping with generic bits.
