2008-02-07vmcoreinfo: fix the configuration dependenciesKen'ichi Ohmichi
This patch fixes the configuration dependencies in the vmcoreinfo data. i386's "node_data" is defined in arch/x86/mm/discontig_32.c, and x86_64's one is defined in arch/x86/mm/numa_64.c.

2008-02-07Introduce flags for reserve_bootmem()Bernhard Walle
This patchset adds a flags variable to reserve_bootmem() and uses the BOOTMEM_EXCLUSIVE flag in crashkernel reservation code to detect collisions between crashkernel area and already used memory. This patch: Change the reserve_bootmem() function to accept a new flag BOOTMEM_EXCLUSIVE. If that flag is set, the function returns with -EBUSY if the memory already has been reserved in the past. This is to avoid conflicts. Because that code runs before SMP initialisation, there's no race condition inside reserve_bootmem_core().

Pavel Emelyanov reported that his networking card did not work and bisected it down to: " The commit 093af8d7f0ba3c6be1485973508584ef081e9f93 x86_32: trim memory by updating e820 broke my e1000 card: on loading driver says that e1000: probe of 0000:04:03.0 failed with error -5 and the interface doesn't appear. " on a 32-bit kernel, base will overflow when try to do PAGE_SHIFT, and highest_addr will always less 4G. So use pfn instead of address to avoid the overflow when more than 4g RAM is installed on a 32-bit kernel. Many thanks to Pavel Emelyanov for reporting and testing it.

This change broke recovery of exceptions in iret: commit 72fe4858544292ad64600765cb78bc02298c6b1c Author: Glauber de Oliveira Costa <gcosta@redhat.com> x86: replace privileged instructions with paravirt macros The ENTRY(native_iret) macro adds alignment padding before the iretq instruction, so "iret_label" no longer points exactly at the instruction. It was sloppy to leave the old "iret_label" label behind when replacing its nearby use. Removing it would have revealed the other use of the label later in the file, and upon noticing that use, anyone exercising the minimum of attention to detail expected of anyone touching this subtle code would realize it needed to change as well.

This patch eliminates numbers in LDT allocation code trying to make it clear to understand from where these numbers come.

2008-02-04x86: remove misleading comments in trampoline_*.SPavel Machek
Both trampolines actually *do* set up stack. (Is the "we jump into compressed/head.S" comment still true?) Signed-off-by: Pavel Machek <pavel@suse.cz> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2008-02-04x86: remove long dead cyrix mtrr codeHarvey Harrison
cyrix_arr_init was #if 0 all the way back to at least v2.6.12. This was the only place where arr3_protected was set to anything but zero. Eliminate this variable.

2008-02-04x86: unify CPU feature string namesH. Peter Anvin
Move the CPU feature string names to a separate file (common to 32 and 64 bits); additionally, make <asm/cpufeature.h> includable by host code in preparation for including the CPU feature strings in the boot code.

2008-02-04x86: cpuid, msr: use inode mutex instead of big kernel lockH. Peter Anvin
Instead of grabbing the BKL on seek, use the inode mutex in the style of generic_file_llseek(). Signed-off-by: H. Peter Anvin <hpa@zytor.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2008-02-04x86: cpuid: allow querying %ecx-sensitive CPUID levelsH. Peter Anvin
After /dev/*/cpuid was introduced, Intel changed the semantics of the CPUID instruction to be sentitive to %ecx as well as %eax. This patch allows querying of %ecx-sensitive levels by placing the %ecx value in the upper 32 bits of the file position (lower 32 bits always were used for the %eax value.) Signed-off-by: H.

2008-02-04x86: rename module scx200_32 to scx200Sam Ravnborg
The module scx200 were renamed to scx200_32 by the merge of the 32 and 64 bit x86 arch trees. Keep the _32 prefix on the .c file as it is 32 bit specific and fix the module name in the Makefile.

2008-02-04x86: restore correct module name for apmSam Ravnborg
The apm module were renamed to apm_32 during the merge of 32 and 64 bit x86 which is unfortunate. As apm is 32 bit specific we like to keep the _32 in the filename but the module should be named apm.
