Gunnar Beutner	54fb5637e7	Kernel: Add missing .globl definitions ... This ensures that we can properly take the address of these symbols in other code.	2021-07-23 22:13:43 +02:00
Gunnar Beutner	f2be1f9326	Kernel: Fix the variable declaration for some linker script symbols ... Despite what the declaration would have us believe these are not "u8*". If they were we wouldn't have to use the & operator to get the address of them and then cast them to "u8*"/FlatPtr afterwards.	2021-07-22 22:27:11 +02:00
Brian Gianforcaro	1cffecbe8d	Kernel: Push ARCH specific ifdef's down into RegisterState functions ... The non CPU specific code of the kernel shouldn't need to deal with architecture specific registers, and should instead deal with an abstract view of the machine. This allows us to remove a variety of architecture specific ifdefs and helps keep the code slightly more portable. We do this by exposing the abstract representation of instruction pointer, stack pointer, base pointer, return register, etc on the RegisterState struct.	2021-07-19 08:46:55 +02:00
Tom	dce18958b6	Kernel: Fix safe_memset not setting the last few bytes in some cases ... Because the remainder variable will always be 0 unless a fault happened we should not use it to decide if we have nothing left to memset when finishing the fast path. This caused not all bytes to be zeroed if the size was not an exact multiple of sizeof(size_t). Fixes #8352	2021-07-04 18:54:16 +02:00
