* [PATCH] asm/signal.h unificationAl Viro2005-05-04
| | | | | | | | | | | | | | | | | New file - asm-generic/signal.h. Contains declarations of __sighandler_t, __sigrestore_t, SIG_DFL, SIG_IGN, SIG_ERR and default definitions of SIG_BLOCK, SIG_UNBLOCK and SIG_SETMASK. asm-*/signal.h switched to including it. The only exception is asm-parisc/signal.h that wants its own declaration of __sighandler_t; that one is left as-is. asm-ppc64/signal.h required one more thing - unlike everybody else it used __sigrestorer_t instead of usual __sigrestore_t. PPC64 switched to common spelling. Signed-off-by: Al Viro <viro@parcelfarce.linux.theplanet.co.uk> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] misc verify_area cleanupsJesper Juhl2005-05-01
| | | | | | | | | | | | | | | | | | There were still a few comments left refering to verify_area, and two functions, verify_area_skas & verify_area_tt that just wrap corresponding access_ok_skas & access_ok_tt functions, just like verify_area does for access_ok - deprecate those. There was also a few places that still used verify_area in commented-out code, fix those up to use access_ok. After applying this one there should not be anything left but finally removing verify_area completely, which will happen after a kernel release or two.

* [PATCH] move SA_xxx defines to linux/signal.hStas Sergeev2005-05-01
| | | | | | | | | | | | | | | | | | | The attached patch moves the IRQ-related SA_xxx flags (namely, SA_PROBE, SA_SAMPLE_RANDOM and SA_SHIRQ) from all the arch-specific headers to linux/signal.h. This looks like a left-over after the irq-handling code was consolidated. The code was moved to kernel/irq/*, but the flags are still left per-arch. Right now, adding a new IRQ flag to the arch-specific header, like this patch does: http://cvs.sourceforge.net/viewcvs.py/*checkout*/alsa/alsa-driver/utils/patches/pcsp-kernel-2.6.10-03.diff?rev=1.1 no longer works, it breaks the compilation for all other arches, unless you add that flag to all the other arch-specific headers too. So I think such a clean-up makes sense. Signed-off-by: Stas Sergeev <stsp@aknet.ru> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

* [PATCH] Increase number of e820 entries hard limit from 32 to 128Venkatesh Pallipadi2005-05-01
| | | | | | | | | | | | | | | | | | | | | | | | | | The specifications that talk about E820 map doesn't have an upper limit on the number of e820 entries. But, today's kernel has a hard limit of 32. With increase in memory size, we are seeing the number of E820 entries reaching close to 32. Patch below bumps the number upto 128. The patch changes the location of EDDBUF in zero-page (as it comes after E820). As, EDDBUF is not used by boot loaders, this patch should not have any effect on bootloader-setup code interface. Patch covers both i386 and x86-64. Tested on: * grub booting bzImage * lilo booting bzImage with EDID info enabled * pxeboot of bzImage Side-effect: bss increases by ~ 2K and init.data increases by ~7.5K on all systems, due to increase in size of static arrays.

* [PATCH] i386: fix hpet for systems that don't support legacy replacementjohn stultz2005-05-01
| | | | | | | | | | | | | | | Currently the i386 HPET code assumes the entire HPET implementation from the spec is present. This breaks on boxes that do not implement the optional legacy timer replacement functionality portion of the spec. This patch, which is very similar to my x86-64 patch for the same issue, fixes the problem allowing i386 systems that cannot use the HPET for the timer interrupt and RTC to still use the HPET as a time source. I've tested this patch on a system systems without HPET, with HPET but without legacy timer replacement, as well as HPET with legacy timer replacement.

* [PATCH] CPUID bug and inconsistency fixH. Peter Anvin2005-05-01
| | | | | | | | | | | | | | The recent support for K8 multicore was misported from x86-64 to i386, due to an unnecessary inconsistency between the CPUID code. Sure, there is are no x86-64 VIA chips yet, but it should happen eventually. This patch fixes the i386 bug as well as makes x86-64 match i386 in the handing of the CPUID array. Signed-off-by: H.

* [PATCH] check nmi watchdog is brokenJack F Vogel2005-05-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | A bug against an xSeries system showed up recently noting that the check_nmi_watchdog() test was failing. I have been investigating it and discovered in both i386 and x86_64 the recent change to the routine to use the cpu_callin_map has uncovered a problem. Prior to that change, on an SMP box, the test was trivally passing because all cpu's were found to not yet be online, but now with the callin_map they are discovered, it goes on to test the counter and they have not yet begun to increment, so it announces a CPU is stuck and bails out. On all the systems I have access to test, the announcement of failure is also bougs... by the time you can login and check /proc/interrupts, the NMI count is happily incrementing on all CPUs. Its just that the test is being done too early. I have tried moving the call to the test around a bit, and it was always too early. I finally hit on this proposed solution, it delays the routine via a late_initcall(), seems like the right solution to me.

* [PATCH] i386/x86_64 segment register access updateH. J. Lu2005-05-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The new i386/x86_64 assemblers no longer accept instructions for moving between a segment register and a 32bit memory location, i.e., movl (%eax),%ds movl %ds,(%eax) To generate instructions for moving between a segment register and a 16bit memory location without the 16bit operand size prefix, 0x66, mov (%eax),%ds mov %ds,(%eax) should be used. It will work with both new and old assemblers. The assembler starting from 2.16.90.0.1 will also support movw (%eax),%ds movw %ds,(%eax) without the 0x66 prefix. I am enclosing patches for 2.4 and 2.6 kernels here. The resulting kernel binaries should be unchanged as before, with old and new assemblers, if gcc never generates memory access for unsigned gsindex; asm volatile("movl %%gs,%0" : "=g" (gsindex)); If gcc does generate memory access for the code above, the upper bits in gsindex are undefined and the new assembler doesn't allow it.

* [PATCH] x86_64: add support for Intel dual-core detection and displayingAndi Kleen2005-04-16
| | | | | | | | | | | | | | | | | | | | | Appended patch adds the support for Intel dual-core detection and displaying the core related information in /proc/cpuinfo. It adds two new fields "core id" and "cpu cores" to x86 /proc/cpuinfo and the "core id" field for x86_64("cpu cores" field is already present in x86_64). Number of processor cores in a die is detected using cpuid(4) and this is documented in IA-32 Intel Architecture Software Developer's Manual (vol 2a) (http://developer.intel.com/design/pentium4/manuals/index_new.htm#sdm_vol2a) This patch also adds cpu_core_map similar to cpu_sibling_map.

* [PATCH] i386: Use loaddebug macro consistentlyRoland McGrath2005-04-16
| | | | | | | | | | | | | | | | This moves the macro loaddebug from asm-i386/suspend.h to asm-i386/processor.h, which is the place that makes sense for it to be defined, removes the extra copy of the same macro in arch/i386/kernel/process.c, and makes arch/i386/kernel/signal.c use the macro in place of its expansion. This is a purely cosmetic cleanup for the normal i386 kernel. However, it is handy for Xen to be able to just redefine the loaddebug macro once instead of also changing the signal.c code.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-16
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
