The documentation is a little iffy as to whether these are actual MMRs, but reading them on the hardware works, and the previous version of this logic (the SDH) had PID[4567]. So add it for RSI too. Signed-off-by: NMike Frysinger <vapier@gentoo.org>

Looks like the copying of MMR defines from the SDH block missed updating the addresses of the RSI_PID# registers. So tweak them to reflect the actual hardware. Signed-off-by: NMike Frysinger <vapier@gentoo.org>

The bf52x/bf54x have the incorrect addresses for USB_EP_NI7_RXINTERVAL and USB_EP_NI7_TXCOUNT, so adjust those. Further, the bf54x header puts the USB defines in the wrong place, so shuffle them back to the right grouping. Signed-off-by: NMike Frysinger <vapier@gentoo.org>

This code was mostly developed against a BF54x, so some BF537-specific issues were missed. The PPI block starts at PPI_CONTROL, not PPI_STATUS (which is the reverse of the EPPI block). The MDMA block starts at MDMA_NEXT_DESC_PTR, not MDMA_CONFIG. Seems the sim does not catch misreads here so that'll need to get fixed. The gptimer block is mostly 32bit regs, not 16bit. Use the gptimer struct to figure that out rather than hardcoding it locally. Signed-off-by: NMike Frysinger <vapier@gentoo.org>

32bit and 64bit on x86 are tested and working. The rest I have looked at closely and I can't find any problems. setns is an easy system call to wire up. It just takes two ints so I don't expect any weird architecture porting problems. While doing this I have noticed that we have some architectures that are very slow to get new system calls. cris seems to be the slowest where the last system calls wired up were preadv and pwritev. avr32 is weird in that recvmmsg was wired up but never declared in unistd.h. frv is behind with perf_event_open being the last syscall wired up. On h8300 the last system call wired up was epoll_wait. On m32r the last system call wired up was fallocate. mn10300 has recvmmsg as the last system call wired up. The rest seem to at least have syncfs wired up which was new in the 2.6.39. v2: Most of the architecture support added by Daniel Lezcano <dlezcano@fr.ibm.com> v3: ported to v2.6.36-rc4 by: Eric W. Biederman <ebiederm@xmission.com> v4: Moved wiring up of the system call to another patch v5: ported to v2.6.39-rc6 v6: rebased onto parisc-next and net-next to avoid syscall conflicts. v7: ported to Linus's latest post 2.6.39 tree. > arch/blackfin/include/asm/unistd.h | 3 ++- > arch/blackfin/mach-common/entry.S | 1 + Acked-by: NMike Frysinger <vapier@gentoo.org> Oh - ia64 wiring looks good.

The software division functions never had unwinding annotations added. Currently, when a division by zero occurs the backtrace shown will stop at Ldiv0 or some completely unrelated function. Add unwinding annotations in hopes of getting a more useful backtrace when a division by zero occurs.

The style that we normally use in asm-generic is to test the macro itself for existence, so in asm-generic, do: #ifndef find_next_zero_bit_le extern unsigned long find_next_zero_bit_le(const void *addr, unsigned long size, unsigned long offset); #endif and in the architectures, write static inline unsigned long find_next_zero_bit_le(const void *addr, unsigned long size, unsigned long offset) #define find_next_zero_bit_le find_next_zero_bit_le This adds the #define for each of the optimized find bitops in the architectures.

由 Daniel Lezcano 提交于
The ns_cgroup is an annoying cgroup at the namespace / cgroup frontier and leads to some problems: * cgroup creation is out-of-control * cgroup name can conflict when pids are looping * it is not possible to have a single process handling a lot of namespaces without falling in a exponential creation time * we may want to create a namespace without creating a cgroup The ns_cgroup was replaced by a compatibility flag 'clone_children', where a newly created cgroup will copy the parent cgroup values. The userspace has to manually create a cgroup and add a task to the 'tasks' file. This patch removes the ns_cgroup as suggested in the following thread: https://lists.linux-foundation.org/pipermail/containers/2009-June/018616.html The 'cgroup_clone' function is removed because it is no longer used. This is a userspace-visible change. Commit 45531757 ("cgroup: notify ns_cgroup deprecated") (merged into 2.6.27) caused the kernel to emit a printk warning users that the feature is planned for removal. Since that time we have heard from XXX users who were affected by this. Signed-off-by: NDaniel Lezcano <daniel.lezcano@free.fr> Signed-off-by: NSerge E.

Commit b87cf80a added support for ARAT (Always Running APIC timer) on AMD processors that are not affected by erratum 400. This erratum is present on certain processor families and prevents APIC timer from waking up the CPU when it is in a deep C state, including C1E state. Determining whether a processor is affected by this erratum may have some corner cases and handling these cases is somewhat complicated. In the interest of simplicity we won't claim ARAT support on processor families below 0x12 and will go back to broadcasting timer when going idle.

This patch provides a shim between the kernel-internal cleancache API (see Documentation/mm/cleancache.txt) and the Xen Transcendent Memory ABI (see http://oss.oracle.com/projects/tmem). Xen tmem provides "hypervisor RAM" as an ephemeral page-oriented pseudo-RAM store for cleancache pages, shared cleancache pages, and frontswap pages. Tmem provides enterprise-quality concurrency, full save/restore and live migration support, compression and deduplication. A presentation showing up to 8% faster performance and up to 52% reduction in sectors read on a kernel compile workload, despite aggressive in-kernel page reclamation ("self-ballooning") can be found at: http://oss.oracle.com/projects/tmem/dist/documentation/presentations/TranscendentMemoryXenSummit2010.pdfSigned-off-by: NDan Magenheimer <dan.magenheimer@oracle.com> Reviewed-by: NJeremy Fitzhardinge <jeremy@goop.org> Cc: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com> Cc: Matthew Wilcox <matthew@wil.cx> Cc: Nick Piggin <npiggin@kernel.dk> Cc: Mel Gorman <mel@csn.ul.ie> Cc: Rik Van Riel <riel@redhat.com> Cc: Jan Beulich <JBeulich@novell.com> Cc: Chris Mason <chris.mason@oracle.com> Cc: Andreas Dilger <adilger@sun.com> Cc: Ted Ts'o <tytso@mit.edu> Cc: Mark Fasheh <mfasheh@suse.com> Cc: Joel Becker <joel.becker@oracle.com> Cc: Nitin Gupta <ngupta@vflare.org>
