* x86: convert cpuinfo_x86 array to a per_cpu arrayMike Travis2007-10-19
| | | | | | | | | | | | | | | | | | | | | | | | | | cpu_data is currently an array defined using NR_CPUS. This means that we overallocate since we will rarely really use maximum configured cpus. When NR_CPU count is raised to 4096 the size of cpu_data becomes 3,145,728 bytes. These changes were adopted from the sparc64 (and ia64) code. An additional field was added to cpuinfo_x86 to be a non-ambiguous cpu index. This corresponds to the index into a cpumask_t as well as the per_cpu index. It's used in various places like show_cpuinfo(). cpu_data is defined to be the boot_cpu_data structure for the NON-SMP case.

* i386: do not BUG_ON() when MSR is unknownStephane Eranian2007-10-19
| | | | | | | | | | | | | | | Here is a small patch to change the behavior of the PMU msr allocator to avoid BUG_ON() when the MSR is unknwon. Instead, it now returns ok, which means "I do not manage". The current allocator is not yet managing the full set of PMU registers (e.g., GLOBAL_* on Core 2).

* x86: acpi use cpu_physical_idMike Travis2007-10-19
| | | | | | | | | | | | | | | | | | | | | | | This is from an earlier message from Christoph Lameter: processor_core.c currently tries to determine the apicid by special casing for IA64 and x86. The desired information is readily available via cpu_physical_id() on IA64, i386 and x86_64.

* x86: convert cpu_llc_id to be a per cpu variableMike Travis2007-10-19
| | | | | | | | | | | | | | | | | Convert cpu_llc_id from a static array sized by NR_CPUS to a per_cpu variable. This saves sizeof(cpu_llc_id) * NR unused cpus. Access is mostly from startup and CPU HOTPLUG functions. Note there's an additional change of the type of cpu_llc_id from int to u8 for ARCH i386 to correspond with the same type in ARCH x86_64.

* x86: convert cpu_to_apicid to be a per cpu variableMike Travis2007-10-19
| | | | | | | | | | | | | | | | | | | | | | | This patch converts the x86_cpu_to_apicid array to be a per cpu variable. This saves sizeof(apicid) * NR unused cpus. Access is mostly from startup and CPU HOTPLUG functions. MP_processor_info() is one of the functions that require access to the x86_cpu_to_apicid array before the per_cpu data area is setup. For this case, a pointer to the __initdata array is initialized in setup_arch() and removed in smp_prepare_cpus() after the per_cpu data area is initialized. A second change is included to change the initial array value of ARCH i386 from 0xff to BAD_APICID to be consistent with ARCH x86_64.

* x86, vsyscall: fix the oops crash with __pa_vsymbol()Siddha, Suresh B2007-10-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | Appended patch fixes an oops while changing the vsyscall sysctl. I am sure no one tested this code before integrating into mainline :( BTW, using ioremap() in vsyscall_sysctl_change() to get the virtual address of a kernel symbol sounds like an over kill.. I wonder if we can define a simple __va_vsymbol() which will return directly the kernel direct mapping. comments in the code which says gcc has trouble with __va(__pa()) sounds bogus to me. __pa() on a vsyscall address will not work anyhow :( And also, the whole nop out syscall in vsyscall page infrastructure (vsyscall_sysctl_change()) is added to make some attacks difficult, and yet I don't see this nop out being done by default. This area requires more cleanups? Fix an oops with __pa_vsymbol(). VSYSCALL_FIRST_PAGE is a fixmap index. We want the starting virtual address of the vsyscall page and not the index.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While we were reviewing pageattr_32/64.c for unification, Thomas Gleixner noticed the following serious SMP bug in global_flush_tlb(): down_read(&init_mm.mmap_sem); list_replace_init(&deferred_pages, &l); up_read(&init_mm.mmap_sem); this is SMP-unsafe because list_replace_init() done on two CPUs in parallel can corrupt the list. This bug has been introduced about a year ago in the 64-bit tree: commit ea7322decb974a4a3e804f96a0201e893ff88ce3 Author: Andi Kleen <ak@suse.de> Date: Thu Dec 7 02:14:05 2006 +0100 [PATCH] x86-64: Speed and clean up cache flushing in change_page_attr down_read(&init_mm.mmap_sem); - dpage = xchg(&deferred_pages, NULL); + list_replace_init(&deferred_pages, &l); up_read(&init_mm.mmap_sem); the xchg() based version was SMP-safe, but list_replace_init() is not. So this "cleanup" introduced a nasty bug. why this bug never become prominent is a mystery - it can probably be explained with the (still) relative obscurity of the x86_64 architecture. the safe fix for now is to write-lock init_mm.mmap_sem.

| | | | | | | | | | | | | | | | | | | | | | | | Do not use *alloc_bootmem_low*(), because ARCH_LOW_ADDRESS_LIMIT is 4GB and this results in boot failures if all of the physical memory in the machine is above 4GB. Signed-off-by: David S. Miller <davem@davemloft.net>
| * | [SPARC64]: Implement atomic backoff.David S. Miller2007-10-17
| |/ | | | | | | | | | | | | | | | | | | When the cpu count is high and contention hits an atomic object, the processors can synchronize such that some cpus continually get knocked out and cannot complete the atomic update. So implement an exponential backoff when SMP. Signed-off-by: David S. Miller <davem@davemloft.net>
