2008-01-30x86: spinlock_32/64 match the jump labels and symbolsThomas Gleixner
Match the jump labels in the 32/64 variants and switch the 64bit version to symbols, so the functions are almost identical except for the operand size now. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-01-30x86: use immediates instead of RW_LOCK_BIAS_STRThomas Gleixner
Use immediate instead of the RW_LOCK_BIAS_STR. Makes the code more readable and gets rid of the string constant. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-01-30x86: fix asm constraints in spinlock_32/64.hThomas Gleixner
Use the correct constraints for the spinlock assembler functions. read (modify) write functions need "+m" instead of "=m" Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-01-30x86: consolidate spinlock.hGlauber de Oliveira Costa
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: Glauber de Oliveira Costa <gcosta@redhat.com> Signed-off-by: Steven Rostedt <rostedt@goodmis.org> Acked-by: Jeremy Fitzhardinge <jeremy@xensource.com> Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2008-01-30x86: irqflags consolidationGlauber de Oliveira Costa
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.

2008-01-30x86: remove extern declarations for code, data, bss resourcesBernhard Walle
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.

2008-01-30x86: remove dead code in ia32-emuCyrill Gorcunov
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.

2008-01-30x86: mtrr use type bool [RESEND AGAIN]Paul Jimenez
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.

2008-01-30x86: pci-calgary_64.c: make a variable staticAdrian Bunk
"debugging" is a horrible name for a global variable - thankfully it can become static. Also put it out of __read_mostly so that gcc no longer has to emit it at all.

Prepare for merging <asm/alternative_{32,64}.h> by making the 32- and 64-bit versions textually identical. This involves: - removing arbitrary header inclusion differences - reorganizing the 32-bit version slightly to match the 64-bit version - using <asm/asm.h> to unify the assembly code - renaming struct paravirt_patch to struct paravirt_patch_site in the 64-bit version to match the 32-bit version; there are no references to struct paravirt_patch elsewhere in the tree.

2008-01-30x86: make i8259_64 more _32-likePaul Jimenez
Howdy! Here's a simple janitorish patch for you: This patch mainly hinges around two includes and their ramifications: #include <i8259.h> which provides cached_{slave,master}_mask #include <io_ports.h> which provides PIC_{MASTER,SLAVE}_{IMR,CMD} Adding these two includes and using those half dozen or so definitions removed 140+ lines of diffs between i8259_32.c and i8259_64.c, thus making it easier for the real substantitive differences between them to show up, and hopefully therefore making it easier to eventually merge the two. All the warnings that checkpatch.pl throws (missing spaces after commas and >80 character lines) exist intentionally to match i8259_32.c.
