Remove GPIO and LPC from WDT reset list

2016-02-22T05:16:02+00:00

WDT reset mode must also be set to SOC mode. These changes are required so host is not interrupted when BMC is reboot. This change will keep the GPIO and LPC units from being reset during an SOC reset. The SOC reset is used to perform a BMC reboot. Signed-off-by: Norman James Signed-off-by: Joel Stanley

arm: dts: unit address should not have 0x prefix

2016-02-11T03:00:43+00:00

The implied format for most bus bindings implies the uname-address part of the unit-name should be in hex without a leading 0x. Fix the one i2c bus that did not follow this convention. Signed-off-by: Milton Miller Signed-off-by: Joel Stanley

ARM/arm64: KVM: correct PTE uncachedness check

2016-01-31T19:25:54+00:00

commit 0de58f852875a0f0dcfb120bb8433e4e73c7803b upstream. Commit e6fab5442345 ("ARM/arm64: KVM: test properly for a PTE's uncachedness") modified the logic to test whether a HYP or stage-2 mapping needs flushing, from [incorrectly] interpreting the page table attributes to [incorrectly] checking whether the PFN that backs the mapping is covered by host system RAM. The PFN number is part of the output of the translation, not the input, so we have to use pte_pfn() on the contents of the PTE, not __phys_to_pfn() on the HYP virtual address or stage-2 intermediate physical address.

ARM/arm64: KVM: test properly for a PTE's uncachedness

2016-01-31T19:25:53+00:00

commit e6fab54423450d699a09ec2b899473a541f61971 upstream. The open coded tests for checking whether a PTE maps a page as uncached use a flawed '(pte_val(xxx) & CONST) != CONST' pattern, which is not guaranteed to work since the type of a mapping is not a set of mutually exclusive bits For HYP mappings, the type is an index into the MAIR table (i.e, the index itself does not contain any information whatsoever about the type of the mapping), and for stage-2 mappings it is a bit field where normal memory and device types are defined as follows: #define MT_S2_NORMAL 0xf #define MT_S2_DEVICE_nGnRE 0x1 I.e., masking *and* comparing with the latter matches on the former, and we have been getting lucky merely because the S2 device mappings also have the PTE_UXN bit set, or we would misidentify memory mappings as device mappings. Since the unmap_range() code path (which contains one instance of the flawed test) is used both for HYP mappings and stage-2 mappings, and considering the difference between the two, it is non-trivial to fix this by rewriting the tests in place, as it would involve passing down the type of mapping through all the functions. However, since HYP mappings and stage-2 mappings both deal with host physical addresses, we can simply check whether the mapping is backed by memory that is managed by the host kernel, and only perform the D-cache maintenance if this is the case.

net: filter: make JITs zero A for SKF_AD_ALU_XOR_X

2016-01-31T19:25:50+00:00

[ Upstream commit 55795ef5469290f89f04e12e662ded604909e462 ] The SKF_AD_ALU_XOR_X ancillary is not like the other ancillary data instructions since it XORs A with X while all the others replace A with some loaded value. All the BPF JITs fail to clear A if this is used as the first instruction in a filter. This was found using american fuzzy lop. Add a helper to determine if A needs to be cleared given the first instruction in a filter, and use this in the JITs. Except for ARM, the rest have only been compile-tested.

arm/aspeed: Enable VUART driver

2016-01-30T00:34:20+00:00

This change makes use of the new VUART device driver. We need a separate compatible property for the VUART node, and a fix for the interrupt definitions. We also change the SCU setup to notify host firmware that the VUART is available. Signed-off-by: Jeremy Kerr
