2011-06-15alpha: fix several security issuesDan Rosenberg1-4/+7
Fix several security issues in Alpha-specific syscalls. Untested, but mostly trivial. 1. Signedness issue in osf_getdomainname allows copying out-of-bounds kernel memory to userland. 2. Signedness issue in osf_sysinfo allows copying large amounts of kernel memory to userland. 3. Typo (?) in osf_getsysinfo bounds minimum instead of maximum copy size, allowing copying large amounts of kernel memory to userland. 4. Usage of user pointer in osf_wait4 while under KERNEL_DS allows privilege escalation via writing return value of sys_wait4 to kernel memory.

2011-06-14x86 idle: APM requires pm_idle/default_idle unconditionally when a moduleAndy Whitcroft1-2/+2
[ Also from Ben Hutchings <ben@decadent.org.uk> and Vitaliy Ivanov <vitalivanov@gmail.com> ] Commit 06ae40ce073d ("x86 idle: EXPORT_SYMBOL(default_idle, pm_idle) only when APM demands it") removed the export for pm_idle/default_idle unless the apm module was modularised and CONFIG_APM_CPU_IDLE was set. But the apm module uses pm_idle/default_idle unconditionally, CONFIG_APM_CPU_IDLE only affects the bios idle threshold. Adjust the export accordingly.

2011-06-14ARM: mach-shmobile: Mackerel USB platform data updateMagnus Damm1-65/+160
This patch updates the board specific USB support code for the sh7372 Mackerel board. With this patch applied port CN22 is driven by the recently added renesas_usbhs driver using the first USB controller included in sh7372 aka USBHS0. Hotplugging of USBHS0 unfortunately has to be handled by software polling. The sh7372 SoC itself obviously supports hotplug notification by IRQ but on the Mackerel board this IRQ happens to be used for the touch screen. Also fix the pinmux configuration to avoid setting up unused pins and fix minor spelling errors. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2011-06-14m68k: use kernel processor defines for conditional optimizationsGreg Ungerer4-23/+19
Older m68k-linux compilers will include pre-defined symbols that confuse what processor it is being targeted for. For example gcc-4.1.2 will pre-define __mc68020__ even if you specify the target processor as -m68000 on the gcc command line. Newer versions of gcc have this corrected. In a few places the m68k code uses defined(__mc68020__) for optimizations that include instructions that are specific to the CPU 68020 and above. When compiling with older compilers this will be true even when we have selected to compile for the older 68000 processors. Switch to using the kernel processor defines, CONFIG_M68020 and friends.

2011-06-14m68knommu: create config options for CPU classesGreg Ungerer1-7/+45
There are 3 families of CPU core types that we support in the m68knommu architecture branch. They are . traditional 68000 . CPU32 (a 68020 core derivative without MMU or bitfield instructions) . ColdFire It will be useful going forward to have a CONFIG_ option defined for each type. We already have one for ColdFire (CONFIG_COLDFIRE), so add for the other 2 families, CONFIG_M68000 and CONFIG_MCPU32. Signed-off-by: Greg Ungerer <gerg@uclinux.org>

2011-06-09exec: delay address limit change until point of no returnMathias Krause2-2/+0
Unconditionally changing the address limit to USER_DS and not restoring it to its old value in the error path is wrong because it prevents us using kernel memory on repeated calls to this function. This, in fact, breaks the fallback of hard coded paths to the init program from being ever successful if the first candidate fails to load. With this patch applied switching to USER_DS is delayed until the point of no return is reached which makes it possible to have a multi-arch rootfs with one arch specific init binary for each of the (hard coded) probed paths. Since the address limit is already set to USER_DS when start_thread() will be invoked, this redundancy can be safely removed.

This patch fixes the following build failure: drivers/built-in.o: In function `early_init_dt_check_for_initrd': /home/florian/dev/kernel/x86/linux-2.6-x86/drivers/of/fdt.c:571: undefined reference to `early_init_dt_setup_initrd_arch' make: *** [.tmp_vmlinux1] Error 1 which happens as soon as we enable initrd support on a x86 devicetree platform such as Intel CE4100.

Commit af3e4fd37a "ARM: 6859/1: Add writethrough dcache support for ARM926EJS processor" broke Thumb2 compilation by omitting to maintain the wide encoding for the added branch instructions which made the ARM926EJ-S record smaller than expected, breaking the record walk code.
