Analyze and fix the following issue in the Linux kernel code: [Blackfin] arch: a rather old performance improvement for the signal handling code
Problem Details: This is a rather old performance improvement for the signal handling code, which was originally only committed on the 2007R1 branch as a workaround for what we suspected to be a hardware bug. There's no point in constructing a sigreturn stub on the stack and flushing caches; we can just make signal ha...

Analyze and fix the following issue in the Linux kernel code: x86: handle BIOSes which terminate e820 with CF=1 and no SMAP
Problem Details: The proper way to terminate the e820 chain is with %ebx == 0 on the last legitimate memory block. However, several BIOSes don't do that and instead return error (CF = 1) when trying to read off the end of the list. For this error return, %eax doesn't necessarily return the SMAP signature -- correctly...
