* x86: don't use word-size specifiers on getuser_64.Glauber Costa2008-07-09

* x86: don't clobber r8 nor use rcx.Glauber Costa2008-07-09
| | | | | | | | | | 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.

* x86: explicitly use edx in const delay function.Glauber Costa2008-07-09
| | | | | | | | | | | | | | 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.

* sysfs: add /sys/firmware/memmapBernhard Walle2008-07-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds /sys/firmware/memmap interface that represents the BIOS (or Firmware) provided memory map. The tree looks like: /sys/firmware/memmap/0/start (hex number) end (hex number) type (string) ... /1/start end type With the following shell snippet one can print the memory map in the same form the kernel prints itself when booting on x86 (the E820 map). --------- 8< -------------------------- #!/bin/sh cd /sys/firmware/memmap for dir in * ; do start=$(cat $dir/start) end=$(cat $dir/end) type=$(cat $dir/type) printf "%016x-%016x (%s)\n" $start $[ $end +1] "$type" done --------- >8 -------------------------- That patch only provides the needed interface: 1. The sysfs interface. 2. The structure and enumeration definition. 3. The function firmware_map_add() and firmware_map_add_early() that should be called from architecture code (E820/EFI, for example) to add the contents to the interface. If the kernel is compiled without CONFIG_FIRMWARE_MEMMAP, the interface does nothing without cluttering the architecture-specific code with #ifdef's. The purpose of the new interface is kexec: While /proc/iomem represents the *used* memory map (e.g. modified via kernel parameters like 'memmap' and 'mem'), the /sys/firmware/memmap tree represents the unmodified memory map provided via the firmware. So kexec can: - use the original memory map for rebooting, - use the /proc/iomem for setting up the ELF core headers for kdump case that should only represent the memory of the system. The patch has been tested on i386 and x86_64.

* x86_32: remove __PAGE_KERNEL(_EXEC)Jeremy Fitzhardinge2008-07-08
| | | | | | | | | | | | | | | | | | | | | | | | | From: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com> Older x86-32 processors do not support global mappings (PGD), so must only use it if the processor supports it. The _PAGE_KERNEL* flags always have _PAGE_KERNEL set, since logically we always want it set. This is OK even on processors which do not support PGD, since all _PAGE flags are masked with __supported_pte_mask before being turned into a real in-pagetable pte. On 32-bit systems, __supported_pte_mask is initialized to not contain _PAGE_GLOBAL, and it is then added if the CPU is found to support it. The x86-32 code used to use __PAGE_KERNEL/__PAGE_KERNEL_EXEC for this purpose, but they're now redundant and can be removed.

This makes 32- and 64-bit code consistent, and removes some special cases where __PAGE_KERNEL* did not have _PAGE_GLOBAL set, causing confusion as a result of the inconsistencies.
