2012-12-18xtensa: add device trees supportMax Filippov7-25/+164
Device trees allow specification of hardware topology and device parameters at runtime instead of hard-coding them in platform setup code. This allows running single binary kernel on a range of compatible boards. New boot parameters tag BP_TAG_FDT is allocated and a pointer to flat device tree is passed in it. Note that current interrupt mapping scheme uses single cell for interrupt identification. That means that IRQ numbers used in DTS must be CPU internal IRQ numbers, not external. It is possible to extend interrupt identification to two cells, and use second cell to tell external IRQ numbers form internal. That would allow to use single DTS on multiple boards with different mapping of external IRQ numbers. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com> Signed-off-by: Chris Zankel <chris@zankel.net>

2012-12-18xtensa: add s32c1i sanity checkMax Filippov3-0/+135
Add a brief sanity test of S32C1I functionality. This instruction is needed by the kernel and userland as part of the base ABI (including GCC atomic builtins, certain threading packages, future atomic support in the C++ standard, etc). However, correct operation of this instruction requires some cooperation by hardware external to the processor (such as bus bridge, bus fabric, or memory controller). Minimally exercising this mechanism and reporting explicit status early in the boot process is helpful to chip vendors using the Linux kernel as a benchmark of correctness of hardware. As it turns out, S32C1I is not exercised by the kernel and by uClibc based userland as of early June 2008. This is expected to change soon as both incorporate more recent open source developments.

2012-12-18h8300: select generic atomic64_t supportFengguang Wu1-0/+1
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: Fengguang Wu <fengguang.wu@intel.com> Cc: "Eric W.

2012-12-18CRIS: fix I/O macrosCorey Minyard1-6/+33
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: David Rientjes <rientjes@google.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
