* [ARM] 5382/1: unwind: Reorganise the stacktrace supportCatalin Marinas2009-02-12
| | | | | | | | | This patch changes the walk_stacktrace and its callers for easier integration of stack unwinding. The arch/arm/kernel/stacktrace.h file is also moved to arch/arm/include/asm/stacktrace.h.

* [ARM] 5388/1: Add hwcap bits for VFPv3 and VFPv3D16Catalin Marinas2009-02-12
| | | | | | | | | | The VFPv3D16 is a VFPv3 CPU configuration where only 16 double registers are present, as the VFPv2 configuration. This patch adds the corresponding hwcap bits so that applications or debuggers have more information about the supported features.

The user_vfp structure defined in asm/user.h contains 32 double registers (to cover VFPv3 and Neon hardware) and the FPSCR register.

| | | | | | | | | | | | | | | | | | | | | | | | xm_x2xx_defconfig currently supports 3 platforms: CM-X255, CM-X270 and EM-X270. Although EM-X270 is similar to CM-X2XX, it has a lot of unique features. Keeping these features in the same _defconfig increases the kernel size in the way it does not fit into CM-X2XX NOR flash.

* | x86-64: fix int $0x80 -ENOSYS returnRoland McGrath2009-02-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
