From: Jaswinder Singh Rajput Date: Thu, 8 Jan 2009 10:13:26 +0000 (+0530) Subject: x86: rename all fields of mpf_intel mpf_X to X X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1eb1b3b65dc3e3ffcc6a60e115c085c0c11c1077;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git x86: rename all fields of mpf_intel mpf_X to X Impact: cleanup, solve 80 columns wrap problems It would be cleaner to rename all the mpf->mpf_X fields to mpf->X - that alone would give 4 characters per usage site. (we already know that it's an 'mpf' entity - no need to duplicate that in the field too) Signed-off-by: Jaswinder Singh Rajput Signed-off-by: Ingo Molnar --- diff --git a/arch/x86/include/asm/mpspec_def.h b/arch/x86/include/asm/mpspec_def.h index 187dc920193..4a7f96d7c18 100644 --- a/arch/x86/include/asm/mpspec_def.h +++ b/arch/x86/include/asm/mpspec_def.h @@ -26,16 +26,16 @@ /* Intel MP Floating Pointer Structure */ struct mpf_intel { - char mpf_signature[4]; /* "_MP_" */ - unsigned int mpf_physptr; /* Configuration table address */ - unsigned char mpf_length; /* Our length (paragraphs) */ - unsigned char mpf_specification;/* Specification version */ - unsigned char mpf_checksum; /* Checksum (makes sum 0) */ - unsigned char mpf_feature1; /* Standard or configuration ? */ - unsigned char mpf_feature2; /* Bit7 set for IMCR|PIC */ - unsigned char mpf_feature3; /* Unused (0) */ - unsigned char mpf_feature4; /* Unused (0) */ - unsigned char mpf_feature5; /* Unused (0) */ + char signature[4]; /* "_MP_" */ + unsigned int physptr; /* Configuration table address */ + unsigned char length; /* Our length (paragraphs) */ + unsigned char specification; /* Specification version */ + unsigned char checksum; /* Checksum (makes sum 0) */ + unsigned char feature1; /* Standard or configuration ? */ + unsigned char feature2; /* Bit7 set for IMCR|PIC */ + unsigned char feature3; /* Unused (0) */ + unsigned char feature4; /* Unused (0) */ + unsigned char feature5; /* Unused (0) */ }; #define MPC_SIGNATURE "PCMP" diff --git a/arch/x86/kernel/mpparse.c b/arch/x86/kernel/mpparse.c index 6cea941c4db..8385d4e7e15 100644 --- a/arch/x86/kernel/mpparse.c +++ b/arch/x86/kernel/mpparse.c @@ -597,9 +597,9 @@ static void __init __get_smp_config(unsigned int early) } printk(KERN_INFO "Intel MultiProcessor Specification v1.%d\n", - mpf->mpf_specification); + mpf->specification); #if defined(CONFIG_X86_LOCAL_APIC) && defined(CONFIG_X86_32) - if (mpf->mpf_feature2 & (1 << 7)) { + if (mpf->feature2 & (1 << 7)) { printk(KERN_INFO " IMCR and PIC compatibility mode.\n"); pic_mode = 1; } else { @@ -610,7 +610,7 @@ static void __init __get_smp_config(unsigned int early) /* * Now see if we need to read further. */ - if (mpf->mpf_feature1 != 0) { + if (mpf->feature1 != 0) { if (early) { /* * local APIC has default address @@ -620,16 +620,16 @@ static void __init __get_smp_config(unsigned int early) } printk(KERN_INFO "Default MP configuration #%d\n", - mpf->mpf_feature1); - construct_default_ISA_mptable(mpf->mpf_feature1); + mpf->feature1); + construct_default_ISA_mptable(mpf->feature1); - } else if (mpf->mpf_physptr) { + } else if (mpf->physptr) { /* * Read the physical hardware table.
