Again, instead of magic constants in the code, declare an enum and be a little bit more explicit. Both in the translations definition and in the loops etc. Signed-off-by:

p2 is already incremented like this few lines below, so do the same for p1. This makes the code easier to follow. Signed-off-by:

The indentation is completely broken in con_get_unimap(). Reorder the code using "if (!cond) continue;"s so that the code makes sense. Switch also the "p" assignment and add a short path using goto. This makes the code readable again. Reviewed-by:

The indentation was completely broken in con_set_unimap(). Reorder the code using 'if (!cond) continue;'s so that the code makes sense. Not that it is perfect now, but it can be followed at least. More cleanup to come. And remove all those useless whitespaces at the EOLs too. Reviewed-by:

It is preferred to use sizeof(*pointer) instead of sizeof(type). First, the type of the variable can change and one needs not change the former (unlike the latter). Second, the latter is error-prone due to (u16), (u16 *), and (u16 **) mixture here. Reviewed-by:

The newly allocated p->uni_pgdir[n] is initialized to NULLs right after a kmalloc_array() allocation. Combine these two using kcalloc(). Reviewed-by:

The code currently does shift, OR, and AND logic directly in the code. It is not much obvious what happens there. Therefore define four macros for that purpose and use them in the code. We use GENMASK() so that it is clear which bits serve what purpose: - UNI_GLYPH: bits 0.. 5 - UNI_ROW: bits 6..10 - UNI_DIR: bits 11..31 Signed-off-by:

Unicode letters are composed as a bit shifts and sums of three values. Use "|" and not "+" for these bit operations. The former is indeed more appropriate. Reviewed-by:

Some lines combine more statements on one line. This makes the code hard to follow. Do it properly in the "one line = one statement" fashion. Reviewed-by:

- int use_unicode -> bool: it's used as bool at some places already, so make it explicit. - int glyph -> u16: every caller passes a u16 in. So make it explicit too. And remove a negative check from inverse_translate() as it never could be negative. Reviewed-by:

This commit changes !CONFIG_CONSOLE_TRANSLATIONS definitions to real (inline) functions. So the commit: * makes type checking much stronger, * removes the need of many parentheses and casts, and * makes the code more readable. Reviewed-by:

The extern keyword is not needed for function declarations. Remove it, so that the consolemap header conforms to other tty headers. Reviewed-by:

Fix invalid indentation and demystify the code by removing superfluous "else"s. The "else"s are unneeded as they always follow an "if"-true branch containing a "return". The code is now way more readable. Reviewed-by:

The code uses constants for sizes of dictionary substructures on many places. Define 3 macros and use them in the code, so that loop bounds, local variables and the dictionary always match. (And the loop bounds are obvious now too.) Reviewed-by:

struct uni_pagedir contains 32 unicode page directories, so the name of the structure is a bit misleading. Rename the structure to uni_pagedict, so it looks like this: struct uni_pagedict -> 32 page dirs -> 32 rows -> 64 glyphs Signed-off-by: -

The bluetooth code uses our bitmap infrastructure for the two bits (!) of connection setup flags, and in the process causes odd problems when it converts between a bitmap and just the regular values of said bits. It's completely pointless to do things like bitmap_to_arr32() to convert a bitmap into a u32. It shoudln't have been a bitmap in the first place. The reason to use bitmaps is if you have arbitrary number of bits you want to manage (not two!), or if you rely on the atomicity guarantees of the bitmap setting and clearing. The code could use an "atomic_t" and use "atomic_or/andnot()" to set and clear the bit values, but considering that it then copies the bitmaps around with "bitmap_to_arr32()" and friends, there clearly cannot be a lot of atomicity requirements. So just use a regular integer. In the process, this avoids the warnings about erroneous use of bitmap_from_u64() which were triggered on 32-bit architectures when conversion from a u64 would access two words (and, surprise, surprise, only one word is needed - and indeed overkill - for a 2-bit bitmap). That was always problematic, but the compiler seems to notice it and warn about the invalid pattern only after commit 0a97953f ("lib: add bitmap_{from,to}_arr64") changed the exact implementation details of 'bitmap_from_u64()', as reported by Sudip Mukherjee and Stephen Rothwell.
