2020-06-27serial: 8250_ingenic: Switch to use platform_get_irq()Andy Shevchenko

2020-06-27serial: kgdboc: Fix bad line wrapping in commentDouglas Anderson
In commit a4912303ac6f ("serial: kgdboc: Allow earlycon initialization to be deferred") it looks like Daniel really took Linus's new suggestion about not needing to wrap at 80 columns to heart and he jammed two full lines of comments into one line. Either that or he just somehow accidentally deleted a carriage return when doing final edits on the patch. In either case let's make it look prettier.

2020-06-27serial: serial-tegra: reduce irq-latency after rx errorsRandolph Maaßen
Since dev_err() calls can lead to synchronous writes to another serial console these calls can provide significant latency during irq-handling in tegra_uart_isr(). With this latency another interrupt is likely to apper during handling of the first interrupt, which might lock up the kernel completely. These errors are reported to the error counters so converting the dev_err() to dev_dbg() is appropriate.

The cursor code used to use magic constants, ANDs, ORs, and some macros. Redefine all this to make some sense. In particular: * Drop CUR_DEFAULT, which is CUR_UNDERLINE. CUR_DEFAULT was used only for cur_default variable initialization, so use CUR_UNDERLINE there to make obvious what's the default. * Drop CUR_HWMASK. Instead, define CUR_SIZE() which explains it more.

2020-06-24vt: convert vc_tab_stop to bitmapJiri Slaby
vc_tab_stop is used as a bitmap, but defined as an unsigned int array. Switch it to bitmap and convert all users to the bitmap interface. Note the difference in behavior! We no longer mask the top 24 bits away from x, hence we do not wrap tabs at 256th column. Instead, we silently drop attempts to set a tab behind 256 columns. And we will also seek by '\t' to the rightmost column, when behind that boundary. I do not think the original behavior was desired and that someone relies on that. If this turns out to be the case, we can change the added 'if's back to masks here and there instead... (Or we can increase the limit as fb consoles now have 240 chars here. And they could have more with higher than my resolution, of course.)

2020-06-24vc: switch state to boolJiri Slaby
The code currently uses bitfields to store true-false values. Switch all of that to bools. Apart from the cleanup, it saves 20B of code as many shifts, ANDs, and ORs became simple movzb's.

2020-06-24vt: introduce enum vc_intensity for intensityJiri Slaby
Introduce names (en enum) for 0, 1, and 2 constants. We now have VCI_HALF_BRIGHT, VCI_NORMAL, and VCI_BOLD instead. Apart from the cleanup, 1) the enum allows for better type checking, and 2) this saves some code. No more fiddling with bits is needed in assembly now. (OTOH, the structure is larger.)
