Hauke Petersen	e7fbaf3815	cpu: removed NAKED attribute from ISRs ... - removed the __attribute__((naked)) from ISRs - removed ISR_ENTER() and ISR_EXIT() macros Rationale: Cortex-Mx MCUs save registers R0-R4 automatically on calling ISRs. The naked attribute tells the compiler not to save any other registers. This is fine, as long as the code in the ISR is not nested. If nested, it will use also R4 and R5, which will then lead to currupted registers on exit of the ISR. Removing the naked will fix this.	2014-10-30 19:33:32 +01:00
