| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 1fcf7ce0c602 (arm: kvm: implement CPU PM notifier) added support for CPU power-management, using a cpu_notifier to re-init KVM on a CPU that entered CPU idle. The code assumed that a CPU entering idle would actually be powered off, loosing its state entierely, and would then need to be reinitialized. It turns out that this is not always the case, and some HW performs CPU PM without actually killing the core. In this case, we try to reinitialize KVM while it is still live. It ends up badly, as reported by Andre Przywara (using a Calxeda Midway): [ 3.663897] Kernel panic - not syncing: unexpected prefetch abort in Hyp mode at: 0x685760 [ 3.663897] unexpected data abort in Hyp mode at: 0xc067d150 [ 3.663897] unexpected HVC/SVC trap in Hyp mode at: 0xc0901dd0 The trick here is to detect if we've been through a full re-init or not by looking at HVBAR (VBAR_EL2 on arm64). This involves implementing the backend for __hyp_get_vectors in the main KVM HYP code (rather small), and checking the return value against the default one when the CPU notifier is called on CPU_PM_EXIT.

| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The testcase data is usable by any platform. This patch moves it into the drivers/of directory so it can be included by any architecture. Using the test cases requires manually adding #include <testcases.dtsi> to the end of the boards .dtsi file and enabling CONFIG_OF_SELFTEST. Not pretty though. A useful project would be to make the testcase code easier to execute. Signed-off-by: Grant Likely <grant.likely@linaro.org>

A scheduled cgroup change drops xattr.h inclusion from cgroup.h and breaks compilation of these three files. Add explicit slab.h includes to the three files. A pending cgroup patch depends on this change and it'd be great if this can be routed through cgroup/for-3.14-fixes branch.

Biggest change is the stage-2 attributes used for for hyp mode which were wrong. I've killed some bits in a couple of DT files which turned out not to be required, and a few other fixes. One fix touches code outside of arch/arm, which is related to sorting out the DMA masks correctly. There is a long standing issue with the conversion from PFNs to addresses where people assume that shifting an unsigned long left by PAGE_SHIFT results in a correct address. This is not the case with C: the integer promotion happens at assignment after evaluation. This fixes the recently introduced dma_max_pfn() function, but there's a number of other places where we try this directly on an unsigned long in the mm code" * 'fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-arm: ARM: 7957/1: add DSB after icache flush in __flush_icache_all() Fix uses of dma_max_pfn() when converting to a limiting address ARM: 7955/1: spinlock: ensure we have a compiler barrier before sev ARM: 7953/1: mm: ensure TLB invalidation is complete before enabling MMU ARM: 7952/1: mm: Fix the memblock allocation for LPAE machines ARM: 7950/1: mm: Fix stage-2 device memory attributes ARM: dts: fix spdif pinmux configuration

In such a case, a waiting CPU may be woken up before the lock has been unlocked, leading to extremely poor performance. This patch reworks the dsb_sev() function to make use of the dsb() macro and ensure ordering against the unlock.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During __v{6,7}_setup, we invalidate the TLBs since we are about to enable the MMU on return to head.S. Unfortunately, without a subsequent dsb instruction, the invalidation is not guaranteed to have completed by the time we write to the sctlr, potentially exposing us to junk/stale translations cached in the TLB. This patch reworks the init functions so that the dsb used to ensure completion of cache/predictor maintenance is also used to ensure completion of the TLB invalidation.

But even after all these fixes, there is still one case where the limit check done with ARCH_LOW_ADDRESS_LIMIT for low memory fails. Russell pointed out the issue with 32 bit LPAE machines in below thread. https://lkml.org/lkml/2014/1/28/364 Since on some LPAE machines where memory start address is beyond 4GB, the low memory marker in memblock will be set to default ARCH_LOW_ADDRESS_LIMIT which is wrong. We can fix this by letting architectures set the ARCH_LOW_ADDRESS_LIMIT using another export similar to memblock_set_current_limit() but am not sure whether its worth the trouble. Tell me if you think otherwise. Rather am just trying to fix that one broken case using memblock_virt_alloc() in setup code since the memblock.current_limit is updated appropriately makes it work on all ARM 32 bit machines.

We were using the stage-1 memory attributes for stage-2 mappings causing device mappings to be mapped as normal memory. Add the S2 equivalent defines for memory attributes and fix the comments explaining the defines while at it. Add a prot_pte_s2 field to the mem_type struct and fill out the field for device mappings accordingly.
