x86: remove SEGMENT_IS_FLAT_CODE

2008-10-13T08:21:32Z

There are no users in the kernel. Signed-off-by: Glauber Costa Signed-off-by: Ingo Molnar

x86: use user_mode macro

2008-10-13T08:21:23Z

Instead of using SEGMENT_IS_KERNEL_CODE, use the "user_mode" macro, which can play the same role. Delete the former, since it now lacks any user. Signed-off-by: Glauber Costa Signed-off-by: Ingo Molnar

x86: consolidate header guards

2008-07-22T19:31:34Z

This patch is the result of an automatic script that consolidates the format of all the headers in include/asm-x86/. The format: 1. No leading underscore. Names with leading underscores are reserved. 2. Pathname components are separated by two underscores. So we can distinguish between mm_types.h and mm/types.h. 3. Everything except letters and numbers are turned into single underscores. Signed-off-by: Vegard Nossum

x86: unify and correct the GDT_ENTRY() macro

2008-07-17T18:29:24Z

Merge the GDT_ENTRY() macro between arch/x86/boot/pm.c and arch/x86/kernel/acpi/sleep.c and put the new one in . While we're at it, correct the bitmasks for the limit and flags. The new version relies on using ULL constants in order to cause type promotion rather than explicit casts; this avoids having to include in . Signed-off-by: H. Peter Anvin

x86: move x86_64 gdt closer to i386

2008-07-08T10:48:16Z

i386 and x86_64 used two different schemes for maintaining the gdt. With this patch, x86_64 initial gdt table is defined in a .c file, same way as i386 is now. Also, we call it "gdt_page", and the descriptor, "early_gdt_descr". This way we achieve common naming, which can allow for more code integration.

x86: don't set up early exception handlers for external interrupts

2008-04-17T15:41:29Z

All of early setup runs with interrupts disabled, so there is no need to set up early exception handlers for vectors >= 32 This saves some minor text size. Signed-off-by: Andi Kleen Cc: mingo@elte.hu Signed-off-by: Thomas Gleixner Signed-off-by: Ingo Molnar

x86: early_idt_handler improvements, 64-bit

2008-01-30T12:33:06Z

It's not too pretty, but I found this made the "PANIC: early exception" messages become much more reliably useful: 1. print the vector number, 2. print the %cs value, 3. handle error-code-pushing vs non-pushing vectors.

x86 setup: initialize LDTR and TR to make life easier to Intel VT

2008-01-30T12:33:02Z

Intel VT doesn't like to engage when the protected-mode state isn't fully initialized. Make life easier for it by initializing LDTR (to null) and TR (to a dummy hunk of low memory which will never actually be touched.) Signed-off-by: H.

x86: : boot GDT entries are 32/64-independent

2008-01-30T12:33:01Z

The boot GDT entries are common between 32- and 64-bit mode, so move them to common code instead of having two identical copies. Signed-off-by: H. Peter Anvin Signed-off-by: Ingo Molnar Signed-off-by: Thomas Gleixner
