9969 72 d 13 h dunkaist /kernel/trunk/ Revert the length of uglobals buffer (fix r9968)

This is a magic number again, but it is reported to work.
 
9968 72 d 16 h dunkaist /kernel/trunk/ kernel, sf9: zero data buffer for empty slots

Now sf9 doesn't read uninitialized memory when called for an empty slot.
Also, applications don't get stale data after sf9 anymore.
 
9967 73 d 14 h dunkaist /kernel/trunk/ Use process_information structure in the kernel

Copied from the userspace macros.inc
 
9964 73 d 23 h dunkaist /kernel/trunk/ Fix sf9 to ignore slot 0

It used to read uninitialized data at SLOT_BASE[0].
 
9958 74 d 17 h dunkaist / Switch to the unified (BIOS and UEFI) kernel image

The initial patch by bzt with my minor edits.

9932 220 d 21 h Doczom /kernel/trunk/ [KERNEL] cleared the code of unnecessary comments  
9930 222 d 22 h Doczom /kernel/trunk/ [KERNEL] The window subsystem has been redesigned:

-added the background_windows constant
-the draw_data array has been deleted
-APPDATA.window and WDATA.thread fields added
-minor fixes in the operation of external file system drivers
 
9926 277 d 2 h Doczom /kernel/trunk/ [KERNEL] the window subsystem was refactored, WDATA structures were expanded and magic numbers were replaced with constants  
9925 280 d 16 h Doczom /kernel/trunk/ [KERNEL] fixed a bug in rev 9917  
9917 285 d 0 h Doczom /kernel/trunk/ [KERNEL]: Replaced magic numbers with constants and cleaned code  
9911 354 d 1 h Doczom /kernel/trunk/ [KERNEL] cleaned code and added description of some functions  
9910 354 d 22 h Doczom /kernel/trunk/ [KERNEL] updated local labels in functions and other small changes  
9897 423 d 16 h dunkaist /kernel/trunk/ [kernel] Fix reading from empty board buffer (sf63.2)

Syscall 63.2, reading from the board buffer, was overwriting registers
edx and ebp when the buffer was empty. Now it sets eax and ebx according
to the kernel API.

Because of this ancient bug BOARD checks the status of sf63.2 syscall
this way:
mcall 63, 2
cmp ebx, 1
jne no_data
; when the buffer is empty, ebx is untouched, i.e. still 2, haha
; edx and ebp are destroyed, the code is lucky not to use them

By the way, the bug was found using umka tool.
 
9831 662 d 4 h dunkaist /kernel/trunk/ Rename fields in SYSCALL_STACK struct: _eax -> eax, etc
