| * s390/bpf,jit: fix address randomizationHeiko Carstens2013-09-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add misssing braces to hole calculation. This resulted in an addition instead of an substraction. Which in turn means that the jit compiler could try to write out of bounds of the allocated piece of memory. This bug was introduced with aa2d2c73 "s390/bpf,jit: address randomize and write protect jit code".

| * | kconfig: do not allow more than one symbol to have 'option modules'Yann E. MORIN2013-09-052-0/+7

Since this does not make much sense, only allow at most one symbol to control tristates. Note: it is still possible to have more than one symbol that control tristates, but indirectly: config MOD1 bool "mod1" select MODULES config MOD2 bool "mod2" select MODULES config MODULES bool option modules Signed-off-by: "Yann E.

| * | kconfig: do not special-case 'MODULES' symbolYann E. MORIN2013-09-052-13/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the 'MODULES' symbol is hard-coded to be the default symbol that enables/disables tristates, if no other symbol was declared with 'option modules'. While this used to be needed for the Linux kernel, we now have an explicit 'option modules' attached to the 'MODULES' symbol (since cset 11097a036), so we no longer need to special-case it in the kconfig code. Furthermore, kconfig is extensively used out of the Linux kernel, and other projects may have another meaning for a symbol named 'MODULES'. This patch changes the way we enable/disable tristates: if a symbol was found with 'option modules' attached to it, then that symbol controls enabling tristates. Otherwise, tristates are disabled, even if a symbol named 'MODULES' exists. Signed-off-by: "Yann E.

| * | modules: do not depend on kconfig to set 'modules' option to symbol MODULESYann E. MORIN2013-08-151-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the MODULES symbol is special-cased in different places in the kconfig language. For example, if no symbol is defined to enable tristates, then kconfig looks up for a symbol named 'MODULES', and forces the 'modules' option onto that symbol. This causes problems as such: - since MODULES is special-cased, reading the configuration with KCONFIG_ALLCONFIG set will forcibly set MODULES to be 'valid' (ie. it has a valid value), when no such value was previously set. So MODULES defaults to 'n' unless it is present in KCONFIG_ALLCONFIG - other third-party projects may decide that 'MODULES' plays a different role for them This has been exposed by cset #cfa98f2e: kconfig: do not override symbols already set and reported by Stephen in: http://marc.info/?l=linux-next&m=137592137915234&w=2 As suggested by Sam, we explicitly define the MODULES symbol to be the tristate-enabler. This will allow us to drop special-casing of MODULES in the kconfig language, later. (Note: this patch is not a fix to Stephen's issue, just a first step).

| * | kconfig: silence warning when parsing auto.conf when a symbol has changed typeYann E. MORIN2013-08-151-3/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a symbol changes type from tristate to bool, and was previously set to 'm', a subsequent silentoldconfig would warn about inconsistency, such as: include/config/auto.conf:3014:warning: symbol value 'm' invalid for HOTPLUG_PCI_PCIE Seen by Linus with the merge in aa8032b (sequence to reproduce by Michal): git checkout 1fe0135 make mrproper make allmodconfig make silentoldconfig git checkout aa8032b make allmodconfig make silentoldconfig Since HOTPLUG_PCI_PCIE changed from tristate to bool in aa8032b, it was previously set to 'm' in auto.conf by the first allmodconfig+silentoldconfig, but then was set to 'y' by the second allmodconfig. Then the second silentoldconfig prints the warning. The warning in this case is a spurious warning, which happens at the time kconfig tries to detect symbols that have changed, to touch the empty header files in include/config used for dependency-tracking by make. Silence the warning when we read the old auto.conf file, since it is perfectly legit that a symbol changed type since the previous call.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Script `config' relies on extensions of `GNU sed', and is thus not working on all Unixes: - in-place edition of files (-i), which can be replaced with a temporary file; - extended-regexps (-r), which can be split into basic regexps; - single-line calls to `a' command, while some implementations require a leading newline before the parameter. Rewrite calls to `sed' to comply with POSIX interface, and move them to helper functions. Signed-off-by: Clement Chauplannaz <chauplac@gmail.com> Tested-by: "Yann E.

The device has many fields that go beyond what is reasonable to report or modify using the existing 'POWER_SUPPLY_PROP_*' properties so the driver exports the register fields via sysfs. They are prefixed by 'f_' (for 'field') to make it easier to distinguish between a register field and a "normal" sysfs file exported by the power_supply infrastructure. Signed-off-by: Mark A.

This slows down the boot process and increases the overall resource usage if the hypervisor has shared processors. This fixes both by implementing a "default" idle that will cede to the hypervisor when possible, in a very simple way without all the bells and whisles of cpuidle.

Then a fix for a regression causing preempt count being off (patch causing this went in v3.12). Lastly are the fixes to make Xen PVHVM guests use PV ticketlocks (Xen PV already does). The enablement of that was supposed to be part of the x86 spinlock merge in commit 816434ec4a67 ("The biggest change here are paravirtualized ticket spinlocks (PV spinlocks), which bring a nice speedup on various benchmarks...") but unfortunatly it would cause hang when booting Xen PVHVM guests. Yours truly got all of the bugs fixed last week and they (six of them) are included in this pull. Bug-fixes: - Boot on ARM without using Xen unconditionally - On Xen ARM don't run cpuidle/cpufreq - Fix regression in balloon driver, preempt count warnings - Fixes to make PVHVM able to use pv ticketlock. - Revert Xen PVHVM disabling pv ticketlock (aka, re-enable pv ticketlocks)" * tag 'stable/for-linus-3.12-rc0-tag-two' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip: xen/spinlock: Don't use __initdate for xen_pv_spin Revert "xen/spinlock: Disable IRQ spinlock (PV) allocation on PVHVM" xen/spinlock: Don't setup xen spinlock IPI kicker if disabled. xen/smp: Update pv_lock_ops functions before alternative code starts under PVHVM xen/spinlock: We don't need the old structure anymore xen/spinlock: Fix locking path engaging too soon under PVHVM. xen/arm: disable cpuidle and cpufreq when linux is running as dom0 xen/p2m: Don't call get_balloon_scratch_page() twice, keep interrupts disabled for multicalls ARM: xen: only set pm function ptrs for Xen guests

Then later in the bootup cycle change the unlock_kick and lock_spinning to the Xen specific - without re patching. That meant that for the core of the kernel we would be running with the baremetal version of unlock_kick and lock_spinning while for modules we would have the proper Xen specific slowpaths. As most of the module uses some API from the core kernel that ended up with slowpath lockers waiting forever to be kicked (b/c they would be using the Xen specific slowpath logic). And the kick never came b/c the unlock path that was taken was the baremetal one. On PV we do not have the problem as we initialise before the alternative code kicks in. The fix is to make the updating of the pv_lock_ops function be done before the alternative code starts patching. Note that this patch fixes issues discovered by commit f10cd522c5fbfec9ae3cc01967868c9c2401ed23. ("xen: disable PV spinlocks on HVM") wherein it mentioned PV spinlocks cannot possibly work with the current code because they are enabled after pvops patching has already been done, and because PV spinlocks use a different data structure than native spinlocks so we cannot switch between them dynamically. The first problem is solved by this patch. The second problem has been solved by commit 816434ec4a674fcdb3c2221a6dffdc8f34020550 (Merge branch 'x86-spinlocks-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip) P.S. There is still the commit 70dd4998cb85f0ecd6ac892cc7232abefa432efb (xen/spinlock: Disable IRQ spinlock (PV) allocation on PVHVM) to revert but that can be done later after all other bugs have been fixed.
