2012-03-02perf/x86/kvm: Fix Host-Only/Guest-Only counting with SVM disabledJoerg Roedel
It turned out that a performance counter on AMD does not count at all when the GO or HO bit is set in the control register and SVM is disabled in EFER. This patch works around this issue by masking out the HO bit in the performance counter control register when SVM is not enabled. The GO bit is not touched because it is only set when the user wants to count in guest-mode only. So when SVM is disabled the counter should not run at all and the not-counting is the intended behaviour.

git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu IOMMU fixes for Linux 3.3-rc5 All the fixes are for the OMAP IOMMU driver. The first patch is the biggest one. It fixes the calls of the function omap_find_iovm_area() in the omap-iommu-debug module which expects a 'struct device' parameter since commit fabdbca instead of an omap_iommu handle. The omap-iommu-debug code still passed the handle to the function which caused a crash. The second patch fixes a NULL pointer dereference in the OMAP code and the third patch makes sure that the omap-iommu is initialized before the omap-isp driver, which relies on the iommu. The last patch is only a workaround until defered probing is implemented. * tag 'iommu-fixes-v3.3-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: ARM: OMAP: make iommu subsys_initcall to fix builtin omap3isp iommu/omap: fix NULL pointer dereference iommu/omap: fix erroneous omap-iommu-debug API calls

2012-02-24[S390] memory hotplug: prevent memory zone interleaveGerald Schaefer
This fixes a kernel oops with CONFIG_DEBUG_VM triggered by a VM_BUG_ON(bad_range()): kernel BUG at mm/page_alloc.c:748. With memory hotplug on System z, it is possible that the memory online/offline state is preserved over a system restart, e.g. there may be offline memory blocks in ZONE_DMA or ZONE_NORMAL. So far, the offline memory range has always been added to ZONE_MOVABLE during system start, so that it was possible to have ZONE_MOVABLE interleave with ZONE_DMA or ZONE_NORMAL. This patch fixes that by checking for zone overlap before adding memory.

There's an s390x assembly wrapper that truncates all the register values to 32-bits and this then calls compat_sys_keyctl() - but the latter only exists if CONFIG_KEYS_COMPAT is enabled, and the s390 Kconfig doesn't enable it.

In commit 54321242afe ("Disable interrupts early in Program Check"), we switched from enabling to disabling interrupts in program_check_common. Whereas ENABLE_INTS leaves r3 untouched, if lockdep is enabled DISABLE_INTS calls into lockdep code and will clobber r3. That means we pass a bogus struct pt_regs* into program_check_exception() and all hell breaks loose. So load our regs pointer into r3 after we call DISABLE_INTS.

2012-02-21sys_poll: fix incorrect type for 'timeout' parameterLinus Torvalds
The 'poll()' system call timeout parameter is supposed to be 'int', not 'long'. Now, the reason this matters is that right now 32-bit compat mode is broken on at least x86-64, because the 32-bit code just calls 'sys_poll()' directly on x86-64, and the 32-bit argument will have been zero-extended, turning a signed 'int' into a large unsigned 'long' value. We could just introduce a 'compat_sys_poll()' function for this, and that may eventually be what we have to do, but since the actual standard poll() semantics is *supposed* to be 'int', and since at least on x86-64 glibc sign-extends the argument before invocing the system call (so nobody can actually use a 64-bit timeout value in user space _anyway_, even in 64-bit binaries), the simpler solution would seem to be to just fix the definition of the system call to match what it should have been from the very start. If it turns out that somebody somehow circumvents the user-level libc 64-bit sign extension and actually uses a large unsigned 64-bit timeout despite that not being how poll() is supposed to work, we will need to do the compat_sys_poll() approach.

2012-02-21OMAP3 EVM: remove out-of-bounds array access of gpio_ledsArnout Vandecappelle (Essensium/Mind)
Otherwise we can get the following warning on some compilers: arch/arm/mach-omap2/board-omap3evm.c:384:11: warning: array subscript is above array bounds The omap3evm BSP enables a GPIO LED on the twl4030 chip. However, the static gpio_leds array doesn't have an entry for it. This is most likely a copy-and-paste error, because it has been in there since the first commit of the omap3evm BSP (53c5ec31).

2012-02-21ARM/audit: include audit header and fix audit archEric Paris
Both bugs being fixed were introduced in: 29ef73b7a823b77a7cd0bdd7d7cded3fb6c2587b Include linux/audit.h to fix below build errors: CC arch/arm/kernel/ptrace.o arch/arm/kernel/ptrace.c: In function 'syscall_trace': arch/arm/kernel/ptrace.c:919: error: implicit declaration of function 'audit_syscall_exit' arch/arm/kernel/ptrace.c:921: error: implicit declaration of function 'audit_syscall_entry' arch/arm/kernel/ptrace.c:921: error: 'AUDIT_ARCH_ARMEB' undeclared (first use in this function) arch/arm/kernel/ptrace.c:921: error: (Each undeclared identifier is reported only once arch/arm/kernel/ptrace.c:921: error: for each function it appears in.) make[1]: *** [arch/arm/kernel/ptrace.o] Error 1 make: *** [arch/arm/kernel] Error 2 This part of the patch is: Reported-by: Axel Lin <axel.lin@gmail.com> Reported-by: Peter Ujfalusi <peter.ujfalusi@ti.com> (They both provided patches to fix it) This patch also (at the request of the list) fixes the fact that ARM has both LE and BE versions however the audit code was called as if it was always BE. If audit userspace were to try to interpret the bits it got from a LE system it would obviously do so incorrectly. Fix this by using the right arch flag on the right system.

2012-02-21ARM: OMAP: fix voltage domain build errors with PM_OPP disabledRussell King
The voltage domain code wants the voltage tables, which are in the opp*.c files. These files aren't built when PM_OPP is disabled, causing the following build errors at link time: twl-common.c:(.init.text+0x2e48): undefined reference to `omap34xx_vddmpu_volt_data' twl-common.c:(.init.text+0x2e4c): undefined reference to `omap34xx_vddcore_volt_data' twl-common.c:(.init.text+0x2e5c): undefined reference to `omap36xx_vddmpu_volt_data' twl-common.c:(.init.text+0x2e60): undefined reference to `omap36xx_vddcore_volt_data' twl-common.c:(.init.text+0x2830): undefined reference to `omap44xx_vdd_mpu_volt_data' twl-common.c:(.init.text+0x283c): undefined reference to `omap44xx_vdd_iva_volt_data' twl-common.c:(.init.text+0x2844): undefined reference to `omap44xx_vdd_core_volt_data' Acked-by: Kevin Hilman <khilman@ti.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
