2007-01-11[PATCH] x86-64: - Ignore long SMI interrupts in clock calibrationJack Steiner
Ensure that no SMI interrupts occur between the read of the HPET & TSC in the clock calibration loop. I noticed that a 2.66GHz system incorrectly detected the processor clock speed about 1/7 of the time: time.c: Detected 2660.005 MHz processor. (most of the time) time.c: Detected 2988.203 MHz processor. (sometime) The problem is caused by an SMI interrupt occuring in hpet_calibrate_tsc() between the read of the HPET & TSC. Prior to switching the BIOS into ACPI mode, it appears that every 27msec an SMI interrupt occurs. The SMI interrupt takes 4.8 msec to process. Note: On my test system, TICK_MIN had to be >380. I picked 5000 to minimize risk of having a value that is too small for other platforms.

2007-01-11[PATCH] i386: make apic probe function non-initVivek Goyal
o struct genapic contains pointer to probe() function which is of type __init. Hence MODPOST generates warning if kernel is compiled with CONFIG_RELOCATABLE=y for i386. WARNING: vmlinux - Section mismatch: reference to .init.text: from .data between 'apic_summit' (at offset 0xc058b504) and 'apic_bigsmp' WARNING: vmlinux - Section mismatch: reference to .init.text: from .data between 'apic_bigsmp' (at offset 0xc058b5a4) and 'cpu.4471' WARNING: vmlinux - Section mismatch: reference to .init.text: from .data between 'apic_es7000' (at offset 0xc058b644) and 'apic_default' WARNING: vmlinux - Section mismatch: reference to .init.text: from .data between 'apic_default' (at offset 0xc058b6e4) and 'interrupt' o One of the possible options is to put special case check in MODPOST to not emit warnings for this case but I think it is not a very good option in terms of maintenance. o Another option is to make probe() function non __init. Anyway this function is really small so not freeing this memory after init is not a big deal. Secondly, from a programming perspective, probably genapic should not provide pointers to functions which have been freed as genapic is non __init and is used even after initialization is complete.

2007-01-11[PATCH] i386: cpu hotplug/smpboot misc MODPOST warning fixesVivek Goyal
o Misc smpboot/cpu hotplug path cleanups. I did those to supress the warnings generated by MODPOST. These warnings are visible only if CONFIG_RELOCATABLE=y. o CONFIG_RELOCATABLE compiles the kernel with --emit-relocs option. This option retains relocation information in vmlinux file and MODPOST is quick to spit out "Section mismatch" warnings. o This patch fixes some of those warnings. Many of the functions in smpboot case are __devinit type and they in turn accesses text/data which if of type __cpuinit. Now if CONFIG_HOTPLUG=y and CONFIG_HOTPLUG_CPU=n then we end up in cases where a function in .text segment is calling another function in .init.text segment and MODPOST emits warning. WARNING: vmlinux - Section mismatch: reference to .init.text:identify_cpu from .text between 'smp_store_cpu_info' (at offset 0xc011020d) and 'do_boot_cpu' WARNING: vmlinux - Section mismatch: reference to .init.text:init_gdt from .text between 'do_boot_cpu' (at offset 0xc01102ca) and '__cpu_up' WARNING: vmlinux - Section mismatch: reference to .init.text:print_cpu_info from .text between 'do_boot_cpu' (at offset 0xc01105d0) and '__cpu_up' o It also fixes the issues where CONFIG_HOTPLUG_CPU=y and start_secondary() is calling smp_callin() which in-turn calls synchronize_tsc_ap() which is of type __init. This should have meant broken CPU hotplug.

2007-01-10 [MIPS] Alchemy: Fix PCI-memory accessAlexander Bigga
The problem was introduced in 2.6.18.3 with the casting of some 36bit-defines (PCI memory) in au1000.h to resource_size_t which may be u32 or u64 depending on the experimental CONFIG_RESOURCES_64BIT. With unset CONFIG_RESOURCES_64BIT, the pci-memory cannot be accessed because the ioremap in arch/mips/au1000/common/pci.c already used the truncated addresses. With set CONFIG_RESOURCES_64BIT, things get even worse, because PCI-scan aborts, due to resource conflict: request_resource() in arch/mips/pci/pci.c fails because the maximum iomem-address is 0xffffffff (32bit) but the pci-memory-start-address is 0x440000000 (36bit). To get pci working again, I propose the following patch: 1. remove the resource_size_t-casting from au1000.h again 2. make the casting in arch/mips/au1000/common/pci.c (it's allowed and necessary here. The 36bit-handling will be done in __fixup_bigphys_addr). With this patch pci works again like in 2.6.18.2, the gcc-compile warnings in pci.c are gone and it doesn't depend on CONFIG_EXPERIMENTAL.

2007-01-09[POWERPC] Fix bugs in the hypervisor call stats codeAnton Blanchard
There were a few issues with the HCALL_STATS code: - PURR cpu feature checks were backwards - We iterated one entry off the end of the hcall_stats array - Remove dead update_hcall_stats() function prototype I noticed one thing while debugging, and that is we call H_ENTER (to set up the MMU hashtable in early init) before we have done the cpu fixups. This means we will execute the PURR SPR reads even on a CPU that isnt capable of it. I wonder if we can move the CPU feature fixups earlier.

When we switched over to the generic BUG mechanism we forgot to change the assembly code which open-codes a WARN_ON() in enter_rtas(), so the bug table got corrupted. This patch provides an EMIT_BUG_ENTRY macro for use in assembly code, and uses it in entry_64.S. Tested with CONFIG_DEBUG_BUGVERBOSE on ppc64 but not without -- I tried to turn it off but it wouldn't go away; I suspect Aunt Tillie probably needed it. This version gets __FILE__ and __LINE__ right in the assembly version -- rather than saying include/asm-powerpc/bug.h line 21 every time which is a little suboptimal.

This will lead to a BUG_ON() if a 32-bit process attempts to make a hugepage mapping which extends above TASK_SIZE (4GB). I'm not sure if these assumptions came about because they were valid with earlier versions of the get_unmapped_area() path, or if it was always broken.

2007-01-08Revert "[PATCH] x86-64: Try multiple timer variants in check_timer"Linus Torvalds
This reverts commit b026872601976f666bae77b609dc490d1834bf77, which has been linked to several problem reports with IO-APIC and the timer. Machines either don't boot because the timer doesn't happen, or we get double timer interrupts because we end up double-routing the timer irq through multiple interfaces. See for example http://lkml.org/lkml/2006/12/16/101 http://lkml.org/lkml/2007/1/3/9 http://bugzilla.kernel.org/show_bug.cgi?id=7789 about some of the discussion. Patches to fix this cleanup exist (and have been confirmed to work fine at least for some of the affected cases) and we'll revisit it for 2.6.21, but this late in the -rc series we're better off just reverting the incomplete commit that caused the problems.

2007-01-08[ARM] Resolve fuse and direct-IO failures due to missing cache flushesRussell King
fuse does not work on ARM due to cache incoherency issues - fuse wants to use get_user_pages() to copy data from the current process into kernel space. However, since this accesses userspace via the kernel mapping, the kernel mapping can be out of date wrt data written to userspace. This can lead to unpredictable behaviour (in the case of fuse) or data corruption for direct-IO. This resolves debian bug #402876 Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

If the kernel attempts to execute a CP1 or CP2 instruction and it aborts, and a FP emulator is not loaded, we try to return as if to a user context, instead of the proper kernel context. Since the fault came from kernel mode, we must use the kernel return paths. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2007-01-05[PATCH] i386: modpost smpboot code warning fixVivek Goyal
o Currently synchronize_tsc_ap() is of type __init. It is called by smp_callin() which is of type __cpuinit. So synchronize_tsc_ap() should be of type __cpuinit. o Modpost generates warnings for i386 if CONFIG_RELOCATABLE=y and CONFIG_HOTPLUG_CPU=y WARNING: vmlinux - Section mismatch: reference to .init.data: from .text between 'start_secondary' (at offset 0xc01164dc) and 'initialize_secondary' WARNING: vmlinux - Section mismatch: reference to .init.data: from .text between 'start_secondary' (at offset 0xc01164e8) and 'initialize_secondary' o tsc is of type __initdata. It should be of type __cpuinitdata. Signed-off-by: Vivek Goyal <vgoyal@in.ibm.com> Cc: Andi Kleen <ak@suse.de> Cc: "Eric W.
