2011-08-23x86-32, vdso: On system call restart after SYSENTER, use int $0x80Gravatar H. Peter Anvin 1-1/+1
When we enter a 32-bit system call via SYSENTER or SYSCALL, we shuffle the arguments to match the int $0x80 calling convention. This was probably a design mistake, but it's what it is now. This causes errors if the system call as to be restarted. For SYSENTER, we have to invoke the instruction from the vdso as the return address is hardcoded. Accordingly, we can simply replace the jump in the vdso with an int $0x80 instruction and use the slower entry point for a post-restart.

2011-08-20sparc: Allow handling signals when stack is corrupted.Gravatar David S. Miller 8-233/+468
If we can't push the pending register windows onto the user's stack, we disallow signal delivery even if the signal would be delivered on a valid seperate signal stack. Add a register window save area in the signal frame, and store any unsavable windows there. On sigreturn, if any windows are still queued up in the signal frame, try to push them back onto the stack and if that fails we kill the process immediately. This allows the debug/tst-longjmp_chk2 glibc test case to pass. Signed-off-by: David S. Miller <davem@davemloft.net>

2011-08-17xen/x86: replace order-based range checking of M2P table by linear oneGravatar Jan Beulich 3-8/+12
The order-based approach is not only less efficient (requiring a shift and a compare, typical generated code looking like this mov eax, [machine_to_phys_order] mov ecx, eax shr ebx, cl test ebx, ebx jnz ... whereas a direct check requires just a compare, like in cmp ebx, [machine_to_phys_nr] jae ... ), but also slightly dangerous in the 32-on-64 case - the element address calculation can wrap if the next power of two boundary is sufficiently far away from the actual upper limit of the table, and hence can result in user space addresses being accessed (with it being unknown what may actually be mapped there). Additionally, the elimination of the mistaken use of fls() here (should have been __fls()) fixes a latent issue on x86-64 that would trigger if the code was run on a system with memory extending beyond the 44-bit boundary.

2011-08-15sparc32: unbreak arch_write_unlock()Gravatar Mikael Pettersson 1-2/+9
The sparc32 version of arch_write_unlock() is just a plain assignment. Unfortunately this allows the compiler to schedule side-effects in a protected region to occur after the HW-level unlock, which is broken. E.g., the following trivial test case gets miscompiled: #include <linux/spinlock.h> rwlock_t lock; int counter; void foo(void) { write_lock(&lock); ++counter; write_unlock(&lock); } Fixed by adding a compiler memory barrier to arch_write_unlock(). The sparc64 version combines the barrier and assignment into a single asm(), and implements the operation as a static inline, so that's what I did too.

2011-08-15sparc64: remove unnecessary macros from spinlock_64.hGravatar Mikael Pettersson 1-6/+0
The sparc64 spinlock_64.h contains a number of operations defined first as static inline functions, and then as macros with the same names and parameters as the functions. Maybe this was needed at some point in the past, but now nothing seems to depend on these macros (checked with a recursive grep looking for ifdefs on these names). Other archs don't define these identity-macros. So this patch deletes these unnecessary macros. Compile-tested with sparc64_defconfig.

2011-08-11ARM: mmp: Also start timer 1 on boot.Gravatar Lennert Buytenhek 1-6/+9
Currently, arch-mmp/time.c uses timer 0 both as a clocksource timer and as a clockevent timer, the latter by setting up a comparator interrupt to match on 'current_time + delta'. This is problematic if delta is small enough, as that can lead to 'current_time + delta' already being in the past when comparator setup has finished, leading to the requested event not triggering. As there is also a silicon issue that requires stopping a timer's counter while writing to one of its match registers, we'll switch to using two separate timers -- timer 0 as clockevent timer, which we'll start and stop on every invocation of ->set_next_event(), and timer 1 as clocksource timer, which will be free-running. This first patch enables timer 1 on boot, so that we can use it as clocksource timer.

2011-08-10x86-64: Rework vsyscall emulation and add vsyscall= parameterGravatar Andy Lutomirski 9-89/+90
There are three choices: vsyscall=native: Vsyscalls are native code that issues the corresponding syscalls. vsyscall=emulate (default): Vsyscalls are emulated by instruction fault traps, tested in the bad_area path. The actual contents of the vsyscall page is the same as the vsyscall=native case except that it's marked NX. This way programs that make assumptions about what the code in the page does will not be confused when they read that code. vsyscall=none: Trying to execute a vsyscall will segfault.

Programs that for some reason don't want to use the vdso should still be able to call getcpu without relying on the slow emulated vsyscall. It costs almost nothing to expose it as a real syscall.

2011-08-10omap: timer: Set dmtimer used as clocksource in autoreload modeGravatar Hemant Pedanekar 1-1/+2
If CONFIG_OMAP_32K_TIMER is not selected and dmtimer is used as clocksource, the timer stops counting once overflow occurs as it was not set in autoreload mode. This results into timekeeping failure: for example, 'sleep 1' at the shell after the timer counter overflow would hang. This patch sets up autoreload when starting the clocksource timer which fixes the above issue. Signed-off-by: Hemant Pedanekar <hemantp@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

2011-08-10OMAP: hwmod: fix build break on non-OMAP4 multi-OMAP2 buildsGravatar Paul Walmsley 1-1/+24
Builds for multi-OMAP2 (e.g., OMAP2420 with OMAP2430) with CONFIG_ARCH_OMAP4=n fail with the following errors: arch/arm/mach-omap2/built-in.o: In function `_enable_module': arch/arm/mach-omap2/omap_hwmod.c:701: undefined reference to `omap4_cminst_module_enable' arch/arm/mach-omap2/built-in.o: In function `_disable_module': arch/arm/mach-omap2/omap_hwmod.c:726: undefined reference to `omap4_cminst_module_disable' arch/arm/mach-omap2/built-in.o: In function `_wait_target_disable': arch/arm/mach-omap2/omap_hwmod.c:1179: undefined reference to `omap4_cminst_wait_module_idle' This is probably due to the preprocessor directives in arch/arm/plat-omap/include/plat/cpu.h that convert some cpu_is_omap*() expressions from preprocessor directives into something that is only resolvable during runtime, if multiple OMAP2 build targets are selected.
