* ARM: davinci: Replace HTTP links with HTTPS onesAlexander A. Klimov2020-07-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

* ARM: 8532/1: uncompress: mark putc as inlineArnd Bergmann2016-02-221-1/+1
| | | | | | | | | | | | | | | | | | | When CONFIG_DEBUG_ICEDCC is set, we don't use the platform specific putc() function, but use icedcc_putc() instead, so putc is unused and causes a compile time warning: In file included from ../arch/arm/boot/compressed/misc.c:28:0: arch/arm/mach-rpc/include/mach/uncompress.h:79:13: warning: 'putc' defined but not used [-Wunused-function] arch/arm/mach-w90x900/include/mach/uncompress.h:30:13: warning: 'putc' defined but not used [-Wunused-function] On most platforms, this does not happen, because putc is defined as 'static inline' so the compiler will automatically drop it when it's unused. This changes the remaining seven platforms to behave the same way. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The tnetv107x support does not compile, and seems to have been broken for a while with nobody caring to fix it. So far everyone I asked said it's probably dead and completely unused and will never again be needed in a future kernel release, so let's delete it. If someone finds a use for this code later and is able to get it to work again, we can always revert the removal.

This makes it easier to use the gpio driver on other platforms as it breaks dependency on mach-davinci. Latencies for gpio_get/set APIs will increase. On measurement, latency was found to have increased by 18 microsecond with gpiolib API as compared to inline APIs. Measurement was done on DA850 EVM for gpio_get_value() API by taking the printk timing across the call with interrupts disabled. inline gpio API with interrupt disabled [ 29.734337] before gpio_get [ 29.736847] after gpio_get Time difference 0.00251 gpio library with interrupt disabled [ 272.876763] before gpio_get [ 272.879291] after gpio_get Time difference 0.002528 Latency increased by (0.002528 - 0.00251) = 18 microsecond.
