2009-02-11x86: move pte types into pgtable*.hJeremy Fitzhardinge
pgtable*.h is intended for definitions relating to actual pagetables and their entries, so move all the definitions for (pte|pmd|pud|pgd)(val)?_t to the appropriate pgtable*.h headers. Signed-off-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com>

2009-02-11x86: rename *-defs.h to *-_types.h for consistencyJeremy Fitzhardinge
The kernel tends to call definition-only headers *_types.h, so rename the x86 page/pgtable headers accordingly. Signed-off-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com>

2009-02-09x86, pgtable.h: fix 2-level 32-bit buildIngo Molnar
- pmd_flags() needs to be available on 2-levels too - provide pud_large() wrapper as well - include page.h - it provides basic types relied on by pgtable.h Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-02-09x86, pgtable.h: macro-ify *_page() methodsIngo Molnar

2009-02-06x86-64: fix int $0x80 -ENOSYS returnRoland McGrath
One of my past fixes to this code introduced a different new bug. When using 32-bit "int $0x80" entry for a bogus syscall number, the return value is not correctly set to -ENOSYS. This only happens when neither syscall-audit nor syscall tracing is enabled (i.e., never seen if auditd ever started). Test program: /* gcc -o int80-badsys -m32 -g int80-badsys.c Run on x86-64 kernel. Note to reproduce the bug you need auditd never to have started. */ #include <errno.h> #include <stdio.h> int main (void) { long res; asm ("int $0x80" : "=a" (res) : "0" (99999)); printf ("bad syscall returns %ld\n", res); return res != -ENOSYS; } The fix makes the int $0x80 path match the sysenter and syscall paths.

Rather than hacking up the headers some more, remove asm/pgtable.h, since early_printk.c doesn't actually need it. Signed-off-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com>
2009-02-06x86: asm/io.h: unify ioremap prototypesJeremy Fitzhardinge
Impact: unify identical code asm/io_32.h and _64.h have identical prototypes for the ioremap family of functions. The 32-bit header had a more descriptive comment. Signed-off-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com>
2009-02-06x86: asm/io.h: unify virt_to_phys/phys_to_virtJeremy Fitzhardinge
Impact: unify identical code asm/io_32.h and _64.h has functionally identical definitions for virt_to_phys, phys_to_virt, page_to_phys, and the isa_* variants, so just unify them. The only slightly functional change is using phys_addr_t for the physical address argument and return val. Signed-off-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com>
2009-02-06x86: make pgd/pud/pmd/pte_none consistentJeremy Fitzhardinge
The _none test is done differently for every level of the pagetable. Standardize them by: 1: Use the native_X_val to extract the raw entry, with no need to go via paravirt_ops, diff -r 1d0646d0d319 arch/x86/include/asm/pgtable.h, and 2: Compare with 0 rather than using a boolean !, since they are actually values and not booleans.
