2019-06-20x86/mm: Rework ioremap resource mapping determinationLianbo Jiang1-26/+45
On ioremap(), __ioremap_check_mem() does a couple of checks on the supplied memory range to determine how the range should be mapped and in particular what protection flags should be used. Generalize the procedure by introducing IORES_MAP_* flags which control different aspects of the ioremapping and use them in the respective helpers which determine which descriptor flags should be set per range.

2019-06-20x86/e820, ioport: Add a new I/O resource descriptor IORES_DESC_RESERVEDLianbo Jiang1-1/+1
When executing the kexec_file_load() syscall, the first kernel needs to pass the e820 reserved ranges to the second kernel because some devices (PCI, for example) need them present in the kdump kernel for proper initialization. But the kernel can not exactly match the e820 reserved ranges when walking through the iomem resources using the default IORES_DESC_NONE descriptor, because there are several types of e820 ranges which are marked IORES_DESC_NONE, see e820_type_to_iores_desc(). Therefore, add a new I/O resource descriptor called IORES_DESC_RESERVED to mark exactly those ranges. It will be used to match the reserved resource ranges when walking through iomem resources.

2019-06-20x86/mm: Create a workarea in the kernel for SME early encryptionThomas Lendacky2-2/+45
In order for the kernel to be encrypted "in place" during boot, a workarea outside of the kernel must be used. This SME workarea used during early encryption of the kernel is situated on a 2MB boundary after the end of the kernel text, data, etc. sections (_end). This works well during initial boot of a compressed kernel because of the relocation used for decompression of the kernel. But when performing a kexec boot, there's a chance that the SME workarea may not be mapped by the kexec pagetables or that some of the other data used by kexec could exist in this range. Create a section for SME in vmlinux.lds.S. Position it after "_end", which is after "__end_of_kernel_reserve", so that the memory will be reclaimed during boot and since this area is all zeroes, it compresses well. This new section will be part of the kernel image, so kexec will account for it in pagetable mappings and placement of data after the kernel. Here's an example of a kernel size without and with the SME section: without: vmlinux: 36,501,616 bzImage: 6,497,344 100000000-47f37ffff : System RAM 1e4000000-1e47677d4 : Kernel code (0x7677d4) 1e47677d5-1e4e2e0bf : Kernel data (0x6c68ea) 1e5074000-1e5372fff : Kernel bss (0x2fefff) with: vmlinux: 44,419,408 bzImage: 6,503,136 880000000-c7ff7ffff : System RAM 8cf000000-8cf7677d4 : Kernel code (0x7677d4) 8cf7677d5-8cfe2e0bf : Kernel data (0x6c68ea) 8d0074000-8d0372fff : Kernel bss (0x2fefff) Signed-off-by: Tom Lendacky <thomas.lendacky@amd.com> Signed-off-by: Borislav Petkov <bp@suse.de> Reviewed-by: Baoquan He <bhe@redhat.com> Reviewed-by: Dave Hansen <dave.hansen@intel.com> Tested-by: Lianbo Jiang <lijiang@redhat.com> Cc: Andy Lutomirski <luto@kernel.org> Cc: Brijesh Singh <brijesh.singh@amd.com> Cc: "H.

2019-06-20x86/mm: Identify the end of the kernel area to be reservedThomas Lendacky3-2/+17
The memory occupied by the kernel is reserved using memblock_reserve() in setup_arch(). Currently, the area is from symbols _text to __bss_stop. Everything after __bss_stop must be specifically reserved otherwise it is discarded. This is not clearly documented. Add a new symbol, __end_of_kernel_reserve, that more readily identifies what is reserved, along with comments that indicate what is reserved, what is discarded and what needs to be done to prevent a section from being discarded.

2019-06-20powerpc/pci/of: Fix OF flags parsing for 64bit BARsAlexey Kardashevskiy1-0/+2
When the firmware does PCI BAR resource allocation, it passes the assigned addresses and flags (prefetch/64bit/...) via the "reg" property of a PCI device device tree node so the kernel does not need to do resource allocation. The flags are stored in resource::flags - the lower byte stores PCI_BASE_ADDRESS_SPACE/etc bits and the other bytes are IORESOURCE_IO/etc. Some flags from PCI_BASE_ADDRESS_xxx and IORESOURCE_xxx are duplicated, such as PCI_BASE_ADDRESS_MEM_PREFETCH/PCI_BASE_ADDRESS_MEM_TYPE_64/etc. When parsing the "reg" property, we copy the prefetch flag but we skip on PCI_BASE_ADDRESS_MEM_TYPE_64 which leaves the flags out of sync. The missing IORESOURCE_MEM_64 flag comes into play under 2 conditions: 1. we remove PCI_PROBE_ONLY for pseries (by hacking pSeries_setup_arch() or by passing "/chosen/linux,pci-probe-only"); 2. we request resource alignment (by passing pci=resource_alignment= via the kernel cmd line to request PAGE_SIZE alignment or defining ppc_md.pcibios_default_alignment which returns anything but 0). Note that the alignment requests are ignored if PCI_PROBE_ONLY is enabled. With 1) and 2), the generic PCI code in the kernel unconditionally decides to: - reassign the BARs in pci_specified_resource_alignment() (works fine) - write new BARs to the device - this fails for 64bit BARs as the generic code looks at IORESOURCE_MEM_64 (not set) and writes only lower 32bits of the BAR and leaves the upper 32bit unmodified which breaks BAR mapping in the hypervisor. This fixes the issue by copying the flag. This is useful if we want to enforce certain BAR alignment per platform as handling subpage sized BARs is proven to cause problems with hotplug (SLOF already aligns BARs to 64k).

The reset line of the RTL8211F PHY is routed to the GPIOZ_15 pad. Describe this in the device tree so the PHY framework can bring the PHY into a known state when initializing it. GPIOZ_15 doesn't support driving the output HIGH (to take the PHY out of reset, only output LOW to reset the PHY is supported). The datasheet states it's an "3.3V input tolerant open drain (OD) output pin". Instead there's a pull-up resistor on the board to take the PHY out of reset. The GPIO itself will be set to INPUT mode to take the PHY out of reset and LOW to reset the PHY, which is achieved with the flags (GPIO_ACTIVE_LOW | GPIO_OPEN_DRAIN).

2019-06-20arm64: dts: meson: use the generic Ethernet PHY reset GPIO bindingsMartin Blumenstingl11-47/+53
The snps,reset-gpio bindings are deprecated in favour of the generic "Ethernet PHY reset" bindings. Replace snps,reset-gpio from the &ethmac node with reset-gpios in the ethernet-phy node. The old snps,reset-active-low property is now encoded directly as GPIO flag inside the reset-gpios property. snps,reset-delays-us is converted to reset-assert-us and reset-deassert-us. reset-assert-us is the second cell from snps,reset-delays-us while reset-deassert-us was the third cell. Instead of blindly copying the old values (which seems strange since they gave the PHY one second to come out of reset) over this also updates the delays based on the datasheets: - the Realtek RTL8211F PHY needs a 10ms assert delay (the datasheet mentions: "For a complete PHY reset, this pin must be asserted low for at least 10ms") and a 30ms deassert delay (the datasheet mentions: "Wait for a further 30ms (for internal circuits settling time) before accessing the PHY register". This applies to the following boards: GXBB NanoPi K2, GXBB Odroid-C2, GXBB Vega S95 variants, GXBB Wetek variants, GXL P230, GXM Khadas VIM2, GXM Nexbox A1, GXM Q200, GXM RBox Pro boards. - the ICPlus IP101GR PHY needs a 10ms assert delay (the datasheet mentions: "Trst | Reset period | 10ms") and a deassert delay of 10ms as well (the datasheet mentions: "Tclk_MII_rdy | MII/RMII clock output ready after reset released | 10ms"). This applies to the GXBB Nexbox A95X board. - the Micrel KSZ9031 seems to require a 100us delay but use the same (seemingly safe) values from RTL8211F due to lack of a board to verify this. This applies to the GXBB P200 board. The GXBB P201 board is left out from this conversion because it doesn't have a dedicated PHY node (because it's not clear which PHY is used on that board).

2019-06-20arm64: dts: meson: g12a: x96-max: fix the Ethernet PHY reset lineMartin Blumenstingl1-3/+4
The Odroid-N2 schematics show that the following pins are used for the reset and interrupt lines: - GPIOZ_14 is the PHY interrupt line - GPIOZ_15 is the PHY reset line The GPIOZ_14 and GPIOZ_15 pins are special. The datasheet describes that they are "3.3V input tolerant open drain (OD) output pins". This means the GPIO controller can drive the output LOW to reset the PHY. To release the reset it can only switch the pin to input mode. The output cannot be driven HIGH for these pins. This requires configuring the reset line as GPIO_OPEN_DRAIN because otherwise the PHY will be stuck in "reset" state (because driving the pin HIGH seems to result in the same signal as driving it LOW). The reset line works together with a pull-up resistor (R143 in the Odroid-N2 schematics). The SoC can drive GPIOZ_14 LOW to assert the PHY reset. However, since the SoC can't drive the pin HIGH (to release the reset) we switch the mode to INPUT and let the pull-up resistor take care of driving the reset line HIGH. Switch to GPIOZ_15 for the PHY reset line instead of using GPIOZ_14 (which actually is the interrupt line). Move from the "snps" specific resets to the MDIO framework's reset-gpios because only the latter honors the GPIO flags. Use the GPIO flags (GPIO_ACTIVE_LOW | GPIO_OPEN_DRAIN) to match with the pull-up resistor because this will: - drive the output LOW to reset the PHY (= active low) - switch the pin to INPUT mode so the pull-up will take the PHY out of reset Fixes: 51d116557b2044 ("arm64: dts: meson-g12a-x96-max: Add Gigabit Ethernet Support") Reviewed-by: Neil Armstrong <narmstrong@baylibre.com> Signed-off-by: Martin Blumenstingl <martin.blumenstingl@googlemail.com> Signed-off-by: Kevin Hilman <khilman@baylibre.com>

The LLVM Target parser currently does not allow to specify the security extension as part of -march (see also LLVM Bug 40186 [0]). When trying to use Clang with LLVM's integrated assembler, this leads to build errors such as this: clang-8: error: the clang compiler does not support '-Wa,-march=armv7-a+sec' Use ".arch_extension sec" to enable the security extension in a more portable fasion. Also make sure to use ".arch armv7-a" in case a v6/v7 multi-platform kernel is being built. Note that this is technically not exactly the same as the old code checked for availabilty of the security extension by calling as-instr. However, there are already other sites which use ".arch_extension sec" unconditionally, hence de-facto we need an assembler capable of ".arch_extension sec" already today (arch/arm/mm/proc-v7.S). The arch extension "sec" is available since binutils 2.21 according to its documentation [1].

2019-06-19s390: fix stfle zero paddingHeiko Carstens1-7/+14
The stfle inline assembly returns the number of double words written (condition code 0) or the double words it would have written (condition code 3), if the memory array it got as parameter would have been large enough. The current stfle implementation assumes that the array is always large enough and clears those parts of the array that have not been written to with a subsequent memset call. If however the array is not large enough memset will get a negative length parameter, which means that memset clears memory until it gets an exception and the kernel crashes. To fix this simply limit the maximum length. Move also the inline assembly to an extra function to avoid clobbering of register 0, which might happen because of the added min_t invocation together with code instrumentation. The bug was introduced with commit 14375bc4eb8d ("[S390] cleanup facility list handling") but was rather harmless, since it would only write to a rather large array. It became a potential problem with commit 3ab121ab1866 ("[S390] kernel: Add z/VM LGR detection"). Since then it writes to an array with only four double words, while some machines already deliver three double words. As soon as machines have a facility bit within the fifth double a crash on IPL would happen.

2019-06-19s390: replace defconfig with performance_defconfigHeiko Carstens2-768/+514
Replace defconfig with performance_defconfig. defconfig had some more or less random debug options enabled, where nobody knows why anymore. Just remove the old defconfig and replace it with performance_defconfig, which reduces the number of configs to maintain. A config with debugging options enabled is debug_defconfig which is supposed to be rather close to performance_defconfig except that is has debug options enabled.

2019-06-19ARM: dts: hip04: Update coresight DT bindingsLeo Yan1-9/+9
CoreSight DT bindings have been updated, thus the old compatible strings are obsolete and the drivers will report warning if DTS uses these obsolete strings. This patch switches to the new bindings for CoreSight dynamic funnel and static replicator, so can dismiss warning during initialisation.
