By not enabling NORETRY by default these paths can run the shrinker and take memory from the system (but not from our own inactive lists because our shrinker can not run whilst we hold the struct mutex) and this may allow the system to survive a little longer whilst our drivers consume all available memory.

* | | | | | | | | mm: add new 'read_cache_page_gfp()' helper functionLinus Torvalds2010-01-272-32/+70
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's a simplified 'read_cache_page()' which takes a page allocation flag, so that different paths can control how aggressive the memory allocations are that populate a address space. In particular, the intel GPU object mapping code wants to be able to do a certain amount of own internal memory management by automatically shrinking the address space when memory starts getting tight. This allows it to dynamically use different memory allocation policies on a per-allocation basis, rather than depend on the (static) address space gfp policy. The actual new function is a one-liner, but re-organizing the helper functions to the point where you can do this with a single line of code is what most of the patch is all about.

It causes a big boot delay because the firmware is not available. See http://marc.info/?l=linux-kernel&m=126267290920060 It also renders the reload sysfs attribute useless. Fixing this is too intrusive for an -rc5 kernel. Thus I'd like to restore the microcode loading behaviour of kernel 2.6.32.

Unequivocally setting the bit in nodes_parsed is insufficient since existing code, such as acpi_get_nodes(), assumes all nodes in the map have online address ranges. In fact, all code using nodes_parsed assumes such nodes represent an address range of online memory. nodes_possible_map is created by unioning nodes_parsed and cpu_nodes_parsed; the former represents nodes with online memory and the latter represents memoryless nodes. We now set the bit for hotpluggable nodes in cpu_nodes_parsed so that it also gets set in nodes_possible_map. [ hpa: Haicheng Li points out that this makes the naming of the variable cpu_nodes_parsed somewhat counterintuitive. However, leave it as is in the interest of keeping the pure bug fix patch small. ] Signed-off-by: David Rientjes <rientjes@google.com> Tested-by: Haicheng Li <haicheng.li@linux.intel.com> LKML-Reference: <alpine.DEB.2.00.1001201152040.30528@chino.kir.corp.google.com> Cc: <stable@kernel.org> Signed-off-by: H.

Static code analysis revealed a potential problem: the intercept_funcs jump table was defined to contain (0x48 >> 2) entries, but we only checked for code > 0x48 which would cause an off-by-one array overflow if code == 0x48. Use the compiler and ARRAY_SIZE to automatically set the limits.

A simple fix is to allow each fd to only trigger one gsi: triggering a storm of interrupts in guest is likely useless anyway, and we can do it by binding a single gsi to many interrupts if we really want to.

The vcpu can pick up the IRR and inject the interrupt before setting the TMR, and perhaps even EOI it, causing incorrect behaviour. The race is really insignificant since it can only occur on the first interrupt (usually following interrupts will not change TMR), but it's better closed than open. Fixed by reordering setting the TMR vs IRR. Cc: stable@kernel.org Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
