| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Treat both negative and zero return values from clk_round_rate() as errors. This is needed since subsequent patches will convert clk_round_rate()'s return value to be an unsigned type, rather than a signed type, since some clock sources can generate rates higher than (2^31)-1 Hz. Eventually, when calling clk_round_rate(), only a return value of zero will be considered a error. All other values will be considered valid rates. The comparison against values less than 0 is kept to preserve the correct behavior in the meantime.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current logic sets the kdump base to min of 2G or ppc64_rma_size/2. On PowerNV kernel the first memory block 'memory@0' can be very large, equal to the DIMM size with ppc64_rma_size value capped to 1G. Hence on PowerNV, kdump base is set to 512M resulting kdump to fail while allocating paca array. This is because, paca need its memory from RMA region capped at 256M (see allocate_pacas()). This patch lowers the kdump base cap to 128M so that kdump kernel can successfully get memory below 256M for paca allocation.

When the PTE is freed, __pte_free_tlb() calls pgtable_page_dtor() with an address to the PTE page that has been converted by page_address(). The mismatch in the PTE's page address causes pgtable_page_dtor() to access invalid memory, so resources for that PTE (such as the page lock) is not properly cleaned up. On PPC32, only SMP kernels are affected. On PPC64, only SMP kernels with 4K page size are affected. This bug was introduced by commit d614bb041209fd7cb5e4b35e11a7b2f6ee8f62b8 "powerpc: Move the pte free routines from common header". On a preempt-rt kernel, a spinlock is dynamically allocated for each PTE in pgtable_page_ctor(). When the PTE is freed, calling pgtable_page_dtor() with a mismatched page address causes a memory leak, as the pointer to the PTE's spinlock is bogus. On mainline, there isn't any immediately obvious symptoms, but the problem still exists here.

Nothing really serious going on. For outstanding issues we still have the S4 fun due to the hsw S4 duct-tape pending (seems like I need to switch into angry maintainer mode on that one). And there's the mode merging revert to make my g33 work again still pending for drm core. For that one I don't have any more clue (and it looks like no one else has a good idea either). And apparently the locking WARN fix in here also needs to be replicated for boot, still confirming that one though. * tag 'drm-intel-fixes-2013-12-02' of git://people.freedesktop.org/~danvet/drm-intel: drm/i915: Pin pages whilst allocating for dma-buf vmap() drm/i915: MI_PREDICATE_RESULT_2 is HSW only drm/i915: Make the DERRMR SRM target global GTT drm/i915: use the correct force_wake function at the PC8 code drm/i915: Fix pipe CSC post offset calculation drm/i915: Simplify DP vs. eDP detection drm/i915: Check VBT for eDP ports on VLV drm/i915: use crtc_htotal in watermark calculations to match fastboot v2 drm/i915: Pin relocations for the duration of constructing the execbuffer drm/i915: take mode config lock around crtc disable at suspend drm/i915: Prefer setting PTE cache age to 3 drm/i915/ddi: set sink to power down mode on dp disable

However, the shrinker can and will reap any object that is unbound if the allocation for the array first fails. This includes the object which we are attempting to vmap(). The solution is to mark the object's pages as pinned whilst we try the allocation to prevent the use-after-free introduced by the potential shrinkage.
