platform/chrome: wilco_ec: Include asm/unaligned instead of linux/ path

2020-02-11T08:10:36Z

It seems that we shouldn't try to include the include/linux/ path to unaligned functions. Just include asm/unaligned.h instead so that we don't run into compilation warnings like below.

platform/chrome: cros_ec: Match implementation with headers

2020-02-03T16:14:50Z

The 'cros_ec' core driver is the common interface for the cros_ec transport drivers to do the shared operations to register, unregister, suspend, resume and handle_event. The interface is provided by including the header 'include/linux/platform_data/cros_ec_proto.h', however, instead of have the implementation of these functions in cros_ec_proto.c, it is in 'cros_ec.c', which is a different kernel module. Apart from being a bad practice, this can induce confusions allowing the users of the cros_ec protocol to call these functions. The register, unregister, suspend, resume and handle_event functions *should* only be called by the different transport drivers (i2c, spi, lpc, etc.), so make this a bit less confusing by moving these functions from the public in-kernel space to a private include in platform/chrome, and then, the interface for cros_ec module and for the cros_ec_proto module is clean.

platform/x86: intel_menlow: switch to use helpers

2020-01-31T18:30:40Z

This switches the intel_menlow driver to use deci_kelvin_to_celsius() and celsius_to_deci_kelvin() in instead of helpers in . This is preparation for centralizing the kelvin to/from Celsius conversion helpers in . This also removes a trailing space, while we're at it.

platform/x86: asus-wmi: switch to use helpers

2020-01-31T18:30:40Z

The asus-wmi driver doesn't implement the thermal device functionality directly, so including just for DECI_KELVIN_TO_CELSIUS() is a bit odd. This switches the asus-wmi driver to use deci_kelvin_to_millicelsius() in . The format string is changed from %d to %ld due to function returned type.

mm, tree-wide: rename put_user_page() to unpin_user_page()

2020-01-31T18:30:38Z

In order to provide a clearer, more symmetric API for pinning and unpinning DMA pages. This way, pin_user_pages*() calls match up with unpin_user_pages*() calls, and the API is a lot closer to being self-explanatory.

goldish_pipe: convert to pin_user_pages() and put_user_page()

2020-01-31T18:30:37Z

1. Call the new global pin_user_pages_fast(), from pin_goldfish_pages(). 2. As required by pin_user_pages(), release these pages via put_user_page(). In this case, do so via put_user_pages_dirty_lock(). That has the side effect of calling set_page_dirty_lock(), instead of set_page_dirty(). This is probably more accurate. As Christoph Hellwig put it, "set_page_dirty() is only safe if we are dealing with a file backed page where we have reference on the inode it hangs off." [1] Another side effect is that the release code is simplified because the page[] loop is now in gup.c instead of here, so just delete the local release_user_pages() entirely, and call put_user_pages_dirty_lock() directly, instead.
