For i386, __range_not_ok is a better name than __range_ok, since it returns 0 when it is in fact okay. Other than that, both versions does not need the word size specifiers, and we remove them. Signed-off-by:

In putuser_32.S and putuser_64.S, replace things like .quad, .long, and explicit references to [r|e]ax for the apropriate macros in asm/asm.h. Signed-off-by:

In putuser_64.S, do it the i386 way, and replace the code in beginning and end of functions with macros, since it's always the same thing. Save lines. Signed-off-by:

Instead of operating over a register we need to put back into normal state afterwards (the memory position), just sub from rbx, which is trashed anyway. We can save a few instructions. Also, this is the i386 way. Signed-off-by:

Instead of clobbering r8, clobber rbx, which is the i386 way. Signed-off-by:

Glauber Costa authored
Follow the pattern, and define a single put_user_x, instead of defining macros for all available sizes. Exception is put_user_8, since the "A" constraint does not give us enough power to specify which register (a or d) to use in the 32-bit common case. Signed-off-by:

Clobber it in the inline asm macros, and let the compiler do this for us. Signed-off-by:

Switch .long and .quad with _ASM_PTR in getuser*.S. Signed-off-by:
-
Glauber Costa authored
There are situations in which the architecture wants to use the register that represents its word-size, whatever it is. For those, introduce __ASM_REG in asm.h, along with the first users _ASM_AX and _ASM_DX. They have users waiting for it, namely the getuser functions. Signed-off-by:

The instructions access registers, so the size is unambiguous. Signed-off-by:

This is for consistency with i386. Signed-off-by:

Glauber Costa authored
Instead of doing a sub after the addition, use the offset directly at the memory operand of the mov instructions. This is the way i386 do. Signed-off-by:

Glauber Costa authored
Since the instructions refer to registers, they'll be able to figure it out. Signed-off-by:

Glauber Costa authored
There's really no reason to clobber r8 or pass the address in rcx. We can safely use only two registers (which we already have to touch anyway) to do the job. Signed-off-by:

delay_32.c, delay_64.c are now equal, and are integrated into delay.c. Signed-off-by:

For x86_64, we can't just use %0, as it would generate a mul against rdx, which is not really what we want (note the ">> 32" in x86_64 version). Using a u64 variable with a shift in i386 generates bad code, so the solution is to explicitly use %%edx in inline assembly for both. Signed-off-by:

This way we achieve the same code for both arches. Signed-off-by:

Glauber Costa authored
This is for consistency with i386. We call use_tsc_delay() at tsc initialization for x86_64, so we'll be always using it. Signed-off-by:

Reorder headers and collect globals in traps_32.c and traps_64.c Code size and data size are unaffected by the changes. Code itself is changed due to different ordering of data and bss. The bss segment changed size due to a change in the packing of the variables. Signed-off-by:

Rename the paravirtualized calculate_cpu_khz to calibrate_tsc. In all cases, we actually calibrate_tsc and use that as the cpu_khz value. Signed-off-by:

Merge the tsc calibration code for the 32bit and 64bit kernel. The paravirtualized calculate_cpu_khz for 64bit now points to the correct tsc_calibrate code as in 32bit. Original native_calculate_cpu_khz for 64 bit is now called as calibrate_cpu. Also moved the recalibrate_cpu_khz function in the common file. Note that this function is called only from powernow K7 cpu freq driver. Signed-off-by:

Move the basic global variable definitions and sched_clock handling in the common "tsc.c" file. - Unify notsc kernel command line handling for 32 bit and 64bit. - Functional changes for 64bit. - "tsc_disabled" is updated if "notsc" is passed at boottime. - Fallback to jiffies for sched_clock, incase notsc is passed on commandline.
