sys/arm/arm genassym.c swtch.S
sys/arm/include asmacros.h atomic.h sysarch.h
Log:
Improve ARM_TP_ADDRESS and RAS area.
De-hardcode usage of ARM_TP_ADDRESS and RAS local storage, and move this
special purpose page to a more convenient place i.e. after the vectors high
page, more towards the end of address space. Previous location (0xe000_0000)
caused grief if KVA was to go beyond the default limit.
Note that ARM world rebuilding is required after this change since the
location of ARM_TP_ADDRESS is shared between kernel and userland.
