2005-08-25[ACPI] IA64-related ACPI Kconfig fixesLen Brown
Build issues were mostly in the ACPI=n case -- don't do that. Select ACPI from IA64_GENERIC. Add some missing dependencies on ACPI. Mark BLACKLIST_YEAR and some laptop-only ACPI drivers as X86-only. Let me know when you get an IA64 Laptop. Signed-off-by: Len Brown <len.brown@intel.com>

2005-08-23[IA64] Fix simulator boot (for real this time).Peter Chubb
Thanks to Stephane, we've now worked out the real cause of the `Linux will not boot on simulator' problem. Turns out it's a stack overflow because the stack pointer wasn't being initialised properly in boot_head.S (it was being initialised to the lowest instead of the highest address of the stack, so the first push started to overwrite data in the BSS).

2005-08-19[PATCH] Mobil Pentium 4 HT and the NMISteven Rostedt
I'm trying to get the nmi working with my laptop (IBM ThinkPad G41) and after debugging it a while, I found that the nmi code doesn't want to set it up for this particular CPU. Here I have: $ cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 15 model : 4 model name : Mobile Intel(R) Pentium(R) 4 CPU 3.33GHz stepping : 1 cpu MHz : 3320.084 cache size : 1024 KB physical id : 0 siblings : 2 core id : 0 cpu cores : 1 fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 3 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe pni monitor ds_cpl est tm2 cid xtpr bogomips : 6642.39 processor : 1 vendor_id : GenuineIntel cpu family : 15 model : 4 model name : Mobile Intel(R) Pentium(R) 4 CPU 3.33GHz stepping : 1 cpu MHz : 3320.084 cache size : 1024 KB physical id : 0 siblings : 2 core id : 0 cpu cores : 1 fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 3 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe pni monitor ds_cpl est tm2 cid xtpr bogomips : 6637.46 And the following code shows: $ cat linux-2.6.13-rc6/arch/i386/kernel/nmi.c [...] void setup_apic_nmi_watchdog (void) { switch (boot_cpu_data.x86_vendor) { case X86_VENDOR_AMD: if (boot_cpu_data.x86 != 6 && boot_cpu_data.x86 != 15) return; setup_k7_watchdog(); break; case X86_VENDOR_INTEL: switch (boot_cpu_data.x86) { case 6: if (boot_cpu_data.x86_model > 0xd) return; setup_p6_watchdog(); break; case 15: if (boot_cpu_data.x86_model > 0x3) return; Here I get boot_cpu_data.x86_model == 0x4. So I decided to change it and reboot. I now seem to have a working NMI. So, unless there's something know to be bad about this processor and the NMI. I'm submitting the following patch.

2005-08-19[SPARC]: Fix weak aliasesAl Viro
sparc_ksyms.c used to declare weak alias to several gcc intrinsics. It doesn't work with gcc4 anymore - it wants a declaration for the thing we are aliasing to and that's not going to happen for something like .mul, etc. Replaced with direct injection of weak alias on the assembler level - .weak <alias> followed by <alias> = <aliased>; that works on all gcc versions.

2005-08-18[IA64] Simulator bootloader fails with gcc 4Ian Wienand
After building a fresh tree with gcc 4 I can't boot the simulator as the bootloader loader dies with loading /home/ianw/kerntest/kerncomp//build/sim_defconfig/vmlinux... failed to read phdr After some investigation I believe this is do with differences between the alignment of variables on the stack between gcc 3 and 4 and the ski simulator. If you trace through with the simulator you can see that the disk_stat structure value returned from the SSC_WAIT_COMPLETION call seems to be only half loaded. I guess it doesn't like the alignment of the input. Signed-off-by: Ian Wienand <ianw@gelato.unsw.edu.au> Signed-off-by: Tony Luck <tony.luck@intel.com>

2005-08-17[ARM] 2850/1: Remove duplicate UART I/O mapping from s3c2410_iodescDimitry Andric
Patch from Dimitry Andric This patch removes the initial UART I/O mapping from s3c2410_iodesc, since the same mapping is already done in the function s3c24xx_init_io in the file arch/arm/mach-s3c2410/cpu.c, through the s3c_iodesc array. I'm not sure if duplicate mappings do any harm, but it's simply redundant. Also, in s3c2440.c the UART I/O mapping is NOT done. Additionally, I put a comma behind the last mapping, to ease copy/pasting stuff around, and make the style consistent with s3c2440.c and other files.

2005-08-16[PATCH] iSeries build with newer assemblers and compilersStephen Rothwell
Paulus suggested that we put xLparMap in its own .c file so that we can generate a .s file to be included into head.S. This doesn't get around the problem of having it at a fixed address, but it makes it more palatable. It would be good if this could be included in 2.6.13 as it solves our build problems with various versions of binutils and gcc. In particular, it allows us to build an iSeries kernel on Debian unstable using their biarch compiler. This has been built and booted on iSeries and built for pSeries and g5.

2005-08-16[IA64]: SN fix bus->sysdata pointer and memory cleanupsPrarit Bhargava
The main issue is that bus_fixup calls may potentially call functions that require a valid bus->sysdata pointer.
