2020-06-27serial: samsung: Minor whitespace cleanupsKrzysztof Kozlowski
Make the code slightly more readable by removing unneeded line breaks, adding missing line breaks and white spaces. This also fixes few strict checkpatch suggestions: CHECK: spaces preferred around that '-' (ctx:VxV) CHECK: Unbalanced braces around else statement CHECK: Lines should not end with a '(' Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org> Link: https://lore.kernel.org/r/20200617152856.18086-1-krzk@kernel.org Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2020-06-24vt_ioctl: eliminate use of uival and ucvalJiri Slaby
They were used for the first parameter of put_user. But put_user accepts constants in the parameter and also determines the type only by the second parameter. So we can safely drop these helpers and simplify the code a bit. Including the removal of set_int label.

2020-06-24vt_ioctl: eliminate ret & breaks in vt_ioctlJiri Slaby
This is still a leftover from BKL, when we locked it around vt_ioctl's code. We can return instead of breaks in the switch loop. And we can return in case of errors too.

2020-06-24vt: redefine world of cursor macrosJiri Slaby
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. And use it all over the places. * Define few more masks and bits which will be used in next patches instead of magic constants. * Define CUR_MAKE to build up cursor value.

2020-06-24vt: make tc write more obvious in vc_con_write_normalJiri Slaby
Nested ternary operators spread over 4 lines are really evil for reading. Turn the outer one to proper 'if'. Now, we see, there is a common path, so the code can be simplified. This way, the code is understandable now. Checked using symbolic execution (klee), that the old and new behaviors are the same.

2020-06-24vc: move normal char processing from do_con_writeJiri Slaby
vc_con_write_normal now handles the complex normal characters processing. It is no longer a part of do_con_write. So this patch makes do_con_write pretty clean and obvious.

2020-06-24vc: extract detecting control characters from do_con_writeJiri Slaby
Move the control characters detection to a separate function dubbed vc_is_control. It makes the 14 subexpressions a "bit" more readable. And also simplifies next patches. It moves also CTRL_ACTION and CTRL_ALWAYS to this new function, as they are used exclusively here. While at it, these are converted to static const variables. And we use "& BIT()" instead of ">>" and "& 1". Checked using symbolic execution (klee), that the old and new behaviors are the same.

2020-06-24vt: move rescan_last_byte label earlierJiri Slaby
This removes duplicated initialization of variables (after reordering 'c' initialization). It will also allow for eliminating whole translation into a separate function in the next patch. Note that vc_state, vc_utf etc. are checked with every rescan now. But they are immutable for non-control characters where rescan might be only necessary.

2020-06-24vt: separate unicode handling into vc_translate_unicodeJiri Slaby
do_con_write is complicated enough. Extract unicode handling to a separate function. For do_con_write, 249 LOCs lowered to 183 lines. Use diff -w -b to see the difference is neligible -- mostly whitespace and use of 'return's instead of 'continue's.

2020-06-24vt: move vc_translate to vt.c and rename itJiri Slaby
vc_translate is used only in vt.c, so move the definition from a header there. Also, it used to be a macro, so be modern and make a static inline from it. This makes the code actually readable. And as a preparation for next patches, rename it to vc_translate_ascii. vc_translate will be a wrapper for both unicode and this one.

2020-06-24vt: get rid of VT10.ID macrosJiri Slaby

2020-06-24vt: use tty_insert_flip_string in respond_stringJiri Slaby
Pass the length of a string to respond_string and use tty_insert_flip_string instead of a loop with tty_insert_flip_char. This simplifies the processing on the tty side. The added strlens are optimized during constant folding and propagation and the result are proper constants in assembly.

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.)

2020-06-24vt: deduplicate setGx codeJiri Slaby
The code for setting G0 and G1 is duplicated -- for each of them. Move the code to a separate function (vc_setGx) and distinguish the two cases by a parameter.

2020-06-24vc: switch state to boolJiri 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.)

2020-06-24vc: separate stateJiri Slaby
There are two copies of some members of struct vc_data. This is because we need to save them and restore later. Move these memebers to a separate structure called vc_state. So now instead of members like: vc_x, vc_y and vc_saved_x, vc_saved_y we have state and saved_state (of type: struct vc_state) containing state.x, state.y and saved_state.x, saved_state.y This change: * makes clear what is saved & restored * eases save & restore by using memcpy (see save_cur and restore_cur) Finally, we document the newly added struct vc_state using kernel-doc.

2020-06-22samples: watch_queue: build sample program for target architectureMasahiro Yamada
This userspace program includes UAPI headers exported to usr/include/. 'make headers' always works for the target architecture (i.e. the same architecture as the kernel), so the sample program should be built for the target as well. Kbuild now supports 'userprogs' for that. I also guarded the CONFIG option by 'depends on CC_CAN_LINK' because $(CC) may not provide libc. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2020-06-22Revert "Makefile: install modules.builtin even if CONFIG_MODULES=n"Masahiro Yamada
This reverts commit e0b250b57dcf403529081e5898a9de717f96b76b, which broke build systems that need to install files to a certain path, but do not set INSTALL_MOD_PATH when invoking 'make install'. $ make INSTALL_PATH=/tmp/destdir install mkdir: cannot create directory ‘/lib/modules/5.8.0-rc1+/’: Permission denied Makefile:1342: recipe for target '_builtin_inst_' failed make: *** [_builtin_inst_] Error 1 While modules.builtin is useful also for CONFIG_MODULES=n, this change in the behavior is quite unexpected. Maybe "make modules_install" can install modules.builtin irrespective of CONFIG_MODULES as Jonas originally suggested. Anyway, that commit should be reverted ASAP.
