2019-08-16ia64: remove support for machvecsChristoph Hellwig
The only thing remaining of the machvecs is a few checks if we are running on an SGI UV system. Replace those with the existing is_uv_system() check that has been rewritten to simply check the OEM ID directly. That leaves us with a generic kernel that is as fast as the previous DIG/ZX1/UV kernels, but can support all hardware. Support for UV and the HP SBA IOMMU is now optional based on new config options.

Add support for compaction for VMware balloon. Since unlike the virtio balloon, we also support huge-pages, which are not going through compaction, we keep these pages in vmballoon and handle this list separately. We use the same lock to protect both lists, as this lock is not supposed to be contended. Doing so also eliminates the need for the page_size lists. We update the accounting as needed to reflect inflation, deflation and migration to be reflected in vmstat.

2019-05-24misc: remove redundant 'default n' from Kconfig-sBartlomiej Zolnierkiewicz
'default n' is the default value for any bool or tristate Kconfig setting so there is no need to write it explicitly. Also since commit f467c5640c29 ("kconfig: only write '# CONFIG_FOO is not set' for visible symbols") the Kconfig behavior is the same regardless of 'default n' being present or not: ... One side effect of (and the main motivation for) this change is making the following two definitions behave exactly the same: config FOO bool config FOO bool default n With this change, neither of these will generate a '# CONFIG_FOO is not set' line (assuming FOO isn't selected/implied). That might make it clearer to people that a bare 'default n' is redundant. ...

2019-05-02clocksource/drivers/tcb_clksrc: Stop depending on atmel_tclibAlexandre Belloni
atmel_tclib is probed too late in the boot process to be able to use the TCB as the boot clocksource. This is an issue for SoCs without the PIT (sams70, samv70 and samv71 families) as they simply currently can't boot. Get rid of the atmel_tclib dependency and probe everything on our own using the correct device tree binding. This also allows getting rid of ATMEL_TCB_CLKSRC_BLOCK and makes the driver a bit more flexible as the TCB is not hardcoded in the kernel anymore.

The IIO driver supports the chip's features more fully, e.g. the ability to power down the output or choose one of the available powerdown modes. There is an oddity with the misc driver in that it initializes the SPI slave to SPI_MODE_0, in contradiction to the datasheet which specifies that data is latched in on the falling edge, implying that SPI_MODE_1 or SPI_MODE_2 must be used. Another oddity is that Kconfig and the MODULE_DESCRIPTION() claim the chip has 16-bit resolution although it actually has 12-bit.

2017-06-03drivers/misc: add Aspeed LPC snoop driverRobert Lippert
This driver enables the LPC snoop hardware on the ASPEED BMC which generates an interrupt upon every write to an I/O port by the host. This is typically used to monitor BIOS boot progress by listening to well-known debug port 80h. The functionality in this commit just saves all snooped values to a circular 2K buffer in the kernel, subsequent commits can act on the values to do things with them.

2017-03-17auxdisplay: charlcd: Extract character LCD core from misc/panelGeert Uytterhoeven
Extract the character LCD core from the Parallel port LCD/Keypad Panel driver in the misc subsystem, and convert it into a subdriver in the auxdisplay subsystem. This allows the character LCD core to be used by other drivers later. Compilation is controlled by its own Kconfig symbol CHARLCD, which is to be selected by its users, but can be enabled manually for compile-testing. All functions changed their prefix from "lcd_" to "charlcd_", and gained a "struct charlcd *" parameter to operate on a specific instance. While the driver API thus is ready to support multiple instances, the current limitation of a single display (/dev/lcd has a single misc minor assigned) is retained. No functional changes intended.

2017-03-17drivers/misc: Add Aspeed LPC control driverCyril Bur
In order to manage server systems, there is typically another processor known as a BMC (Baseboard Management Controller) which is responsible for powering the server and other various elements, sometimes fans, often the system flash. The Aspeed BMC family which is what is used on OpenPOWER machines and a number of x86 as well is typically connected to the host via an LPC (Low Pin Count) bus (among others). The LPC bus is an ISA bus on steroids. It's generally used by the BMC chip to provide the host with access to the system flash (via MEM/FW cycles) that contains the BIOS or other host firmware along with a number of SuperIO-style IOs (via IO space) such as UARTs, IPMI controllers. On the BMC chip side, this is all configured via a bunch of registers whose content is related to a given policy of what devices are exposed at a per system level, which is system/vendor specific, so we don't want to bolt that into the BMC kernel. This started with a need to provide something nicer than /dev/mem for user space to configure these things. One important aspect of the configuration is how the MEM/FW space is exposed to the host (ie, the x86 or POWER). Some registers in that bridge can define a window remapping all or portion of the LPC MEM/FW space to a portion of the BMC internal bus, with no specific limits imposed in HW. I think it makes sense to ensure that this window is configured by a kernel driver that can apply some serious sanity checks on what it is configured to map. In practice, user space wants to control this by flipping the mapping between essentially two types of portions of the BMC address space: - The flash space. This is a region of the BMC MMIO space that more/less directly maps the system flash (at least for reads, writes are somewhat more complicated). - One (or more) reserved area(s) of the BMC physical memory. The latter is needed for a number of things, such as avoiding letting the host manipulate the innards of the BMC flash controller via some evil backdoor, we want to do flash updates by routing the window to a portion of memory (under control of a mailbox protocol via some separate set of registers) which the host can use to write new data in bulk and then request the BMC to flash it. There are other uses, such as allowing the host to boot from an in-memory flash image rather than the one in flash (very handy for continuous integration and test, the BMC can just download new images). It is important to note that due to the way the Aspeed chip lets the kernel configure the mapping between host LPC addresses and BMC ram addresses the offset within the window must be a multiple of size. Not doing so will fragment the accessible space rather than simply moving 'zero' upwards. This is caused by the nature of HICR8 being a mask and the way host LPC addresses are translated.

2017-01-25misc: sram: Integrate protect-exec reserved sram area typeDave Gerlach
Introduce a new "protect-exec" reserved sram area type which is makes use of the the existing functionality provided for the "pool" sram region type for use with the genalloc framework and with the added requirement that it be maintained as read-only and executable while allowing for an arbitrary number of drivers to share the space. This introduces a common way to maintain a region of sram as read-only and executable and also introduces a helper function, sram_exec_copy, which allows for copying data to this protected region while maintaining locking to avoid conflicts between multiple users of the same space. A region of memory that is marked with the "protect-exec" flag in the device tree also has the requirement of providing a page aligned block of memory so that the page attribute manipulation does not affect surrounding regions. Also, selectively enable this only for builds that support set_memory_* calls, for now just ARM, through the use of Kconfig.
