We shoud use core id bits instead of max cores, in case later with AMD downcores Quad core Opteron. [ tglx: arch/x86 adaptation ] Signed-off-by:

We need to store core id bits to cpuinfo_x86 in early_identify_cpu. So we use it to create acpiid_to_node array in k8topolgy.c Signed-off-by:

Contrary to the comment "newer gccs do it by default", newer gcc versions default to -maccumulate-outgoing-args only with CONFIG_CC_OPTIMIZE_FOR_SIZE=n, and then only with some CPU settings. Measured with an i386 defconfig, gcc 4.2.1 and kernel 2.6.23-rc1 ("orig" is the plain kernel, "changed is with -maccumulate-outgoing-args removed): $ ls -la vmlinux* -rwxrwxr-x 1 bunk bunk 6269713 2007-07-24 22:19 vmlinux.changed -rwxrwxr-x 1 bunk bunk 6425361 2007-07-24 22:19 vmlinux.orig $ size vmlinux.* text data bss dec hex filename 4493465 504108 614400 5611973 55a1c5 vmlinux.changed 4646160 504108 614400 5764668 57f63c vmlinux.orig $ That's a 2.5% size increase that does for sure hurt small systems. If the stack unwinder ever comes back and needs this as indicated in the comment, adding it to the cflags when the user enabled the unwinder should be a better option.

4 socket quad core, 8 socket quad core will do apic ID lifting for BSP. But io-apic regs for ExtINT still use 0 as dest. so when we enable apic error vector in BSP, we will get one APIC error. CPU: L1 I Cache: 64K (64 bytes/line), D cache 64K (64 bytes/line) CPU: L2 Cache: 512K (64 bytes/line) CPU 0/4 -> Node 0 CPU: Physical Processor ID: 1 CPU: Processor Core ID: 0 SMP alternatives: switching to UP code ACPI: Core revision 20070126 enabled ExtINT on CPU#0 ESR value after enabling vector: 00000000, after 0000000c APIC error on CPU0: 0c(08) ENABLING IO-APIC IRQs Synchronizing Arb IDs. So move enable_IO_APIC from setup_IO_APIC into setup_local_APIC and call it before enabling the ACPI error vector. [ tglx: arch/x86 adaptation ] Signed-off-by:

Using a variable name, which is the same as a macro name is not really smart. Change the variable names and fixup all users. Signed-off-by:

The cli and sti instructions need to be replaced by paravirt hooks. For the i386 architecture, this is already done. The code requirements aren't much different from x86_64 POV, so this part is consolidated in the common header Signed-off-by:

This patch consolidates the irqflags include files containing common paravirt definitions. The native definition for interrupt handling, halt, and such, are the same for 32 and 64 bit, and they are kept in irqflags.h. the differences are split in the arch-specific files. The syscall function, irq_enable_sysexit, has a very specific i386 naming, and its name is then changed to a more general one. Signed-off-by:

This patch removes the extern struct resource declarations for data_resource, code_resource and bss_resource on x86 and declares that three structures as static as done on other architectures like IA64. On i386, these structures are moved to setup_32.c (from e820_32.c) because that's code that is not specific to e820 and also required on EFI systems. That makes the "extern" reference superfluous. On x86_64, data_resource, code_resource and bss_resource are passed to e820_reserve_resources() as arguments just as done on i386 and IA64. That also avoids the "extern" reference and it's possible to make it static. Signed-off-by:

Remove useless second time checking of fsave argument in save_i387_ia32() routine. It's possible the compiler is doing the same but that is much better to remove the dead code explicitly. Signed-off-by:

This is a janitorish patch to 1) remove private TRUE/FALSE #def's in favor of using the standard enum from linux/stddef.h and 2) switch the variables holding those values to type 'bool' (from linux/types.h) since it both seems more appropriate and allows for potentially better optimization. As a truly minor aside, I removed a couple of comments documenting a 'do_safe' parameter that seems to no longer exist. Signed-off-by:
