2010-10-05[PATCH 2/2] IPS driver: disable CPU turboJesse Barnes
The undocumented interface we're using for reading CPU power seems to be overreporting power. Until we figure out how to correct it, disable CPU turbo and power reporting to be safe. This will keep the CPU within default limits and still allow us to increase GPU frequency as needed.

2010-10-05intel_ips -- ensure we do not enable gpu turbo mode without driver linkageAndy Whitcroft
Both when polling the current turbo status (in poll_turbo_status mode) and when handling thermal events (in ips_irq_handler) the current status of GPU turbo is updated to match the hardware status. However if during driver initialisation we were unable aquire linkage to the i915 driver enabling GPU turbo will lead to an oops on the first attempt to determine GPU busy status. Ensure that we do not enable GPU turbo unless we have driver linkage.

2010-10-05wait: using uninitialized member of wait queueEvgeny Kuznetsov
The "flags" member of "struct wait_queue_t" is used in several places in the kernel code without beeing initialized by init_wait(). "flags" is used in bitwise operations. If "flags" not initialized then unexpected behaviour may take place. Incorrect flags might used later in code. Added initialization of "wait_queue_t.flags" with zero value into "init_wait". Signed-off-by: Evgeny Kuznetsov <EXT-Eugeny.Kuznetsov@nokia.com> [ The bit we care about does end up being initialized by both prepare_to_wait() and add_to_wait_queue(), so this doesn't seem to cause actual bugs, but is definitely the right thing to do -Linus ] Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2010-10-05modules: Fix module_bug_list list corruption raceLinus Torvalds
With all the recent module loading cleanups, we've minimized the code that sits under module_mutex, fixing various deadlocks and making it possible to do most of the module loading in parallel. However, that whole conversion totally missed the rather obscure code that adds a new module to the list for BUG() handling. That code was doubly obscure because (a) the code itself lives in lib/bugs.c (for dubious reasons) and (b) it gets called from the architecture-specific "module_finalize()" rather than from generic code. Calling it from arch-specific code makes no sense what-so-ever to begin with, and is now actively wrong since that code isn't protected by the module loading lock any more. So this commit moves the "module_bug_{finalize,cleanup}()" calls away from the arch-specific code, and into the generic code - and in the process protects it with the module_mutex so that the list operations are now safe. Future fixups: - move the module list handling code into kernel/module.c where it belongs. - get rid of 'module_bug_list' and just use the regular list of modules (called 'modules' - imagine that) that we already create and maintain for other reasons.

2010-10-05omap: iommu-load cam register before flushing the entryHari Kanigeri
The flush_iotlb_page is not loading the cam register before flushing the cam entry. This causes wrong entry to be flushed out from the TLB, and if the entry happens to be a locked TLB entry it would lead to MMU faults. The fix is to load the cam register with the address to be flushed before flushing the TLB entry.

2010-10-05xen: do not set xenstored_ready before xenbus_probe on hvmStefano Stabellini
Register_xenstore_notifier should guarantee that the caller gets notified even if xenstore is already up. Therefore we revert "do not notify callers from register_xenstore_notifier" and set xenstored_read at the right time for PV on HVM guests too. In fact in case of PV on HVM guests xenstored is ready only after the platform pci driver has completed the initialization, so do not set xenstored_ready before the call to xenbus_probe(). This patch fixes a shutdown_event watcher registration bug that causes "xm shutdown" not to work properly.

2010-10-04ARM: 6386/1: flush_ptrace_access: invalidate correct I-cache aliasWill Deacon
copy_to_user_page can be used by access_process_vm to write to an executable page of a process using a mapping acquired by kmap. For systems with I-cache aliasing, flushing the I-cache using the Kernel mapping may leave stale data in the I-cache if the user mapping is of a different colour. This patch introduces a flush_icache_alias function to flush.c, which calls flush_icache_range with a mapping of the specified colour. flush_ptrace_access is then modified to call this new function instead of coherent_kern_range in the case of an aliasing I-cache and a non-aliasing D-cache.

2010-10-04ARM: 6385/1: setup: detect aliasing I-cache when D-cache is non-aliasingWill Deacon
Currently, the Kernel assumes that if a CPU has a non-aliasing D-cache then the I-cache is also non-aliasing. This may not be true on ARM cores from v6 onwards, which may have aliasing I-caches but non-aliasing D-caches. This patch adds a cpu_has_aliasing_icache function, which is called from cacheid_init and adds CACHEID_VIPT_I_ALIASING to the cacheid when appropriate. A utility macro, icache_is_vipt_aliasing(), is also provided. Signed-off-by: Will Deacon <will.deacon@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2010-10-04ARM: Allow SMP kernels to boot on UP systemsRussell King
UP systems do not implement all the instructions that SMP systems have, so in order to boot a SMP kernel on a UP system, we need to rewrite parts of the kernel. Do this using an 'alternatives' scheme, where the kernel code and data is modified prior to initialization to replace the SMP instructions, thereby rendering the problematical code ineffectual. We use the linker to generate a list of 32-bit word locations and their replacement values, and run through these replacements when we detect a UP system.
