-Subject: [PATCH 2/4] tg3: APE heartbeat changes
-
-In ungraceful host shutdown or driver crash case BMC connectivity is
-lost. APE firmware is missing the driver state in this
-case to keep the BMC connectivity alive.
-This patch has below change to address this issue.
-
-Heartbeat mechanism with APE firmware. This heartbeat mechanism
-is needed to notify the APE firmware about driver state.
-
-This patch also has the change in wait time for APE event from
-1ms to 20ms as there can be some delay in getting response.
-
-v2: Drop inline keyword as per David suggestion.

+Subject: [PATCH 3/4] powerpc/mm/radix: Fix checkstops caused by invalid tlbiel
+
+In tlbiel_radix_set_isa300() we use the PPC_TLBIEL() macro to
+construct tlbiel instructions. The instruction takes 5 fields, two of
+which are registers, and the others are constants. But because it's
+constructed with inline asm the compiler doesn't know that.
+
+We got the constraint wrong on the 'r' field, using "r" tells the
+compiler to put the value in a register. The value we then get in the
+macro is the *register number*, not the value of the field.
+
+That means when we mask the register number with 0x1 we get 0 or 1
+depending on which register the compiler happens to put the constant
+in, eg:
+
+  li      r10,1
+  tlbiel  r8,r9,2,0,0
+
+  li      r7,1
+  tlbiel  r10,r6,0,0,1
+
+If we're unlucky we might generate an invalid instruction form, for
+example RIC=0, PRS=1 and R=0, tlbiel r8,r7,0,1,0, this has been
+observed to cause machine checks:
+
+  Oops: Machine check, sig: 7 [#1]
+  CPU: 24 PID: 0 Comm: swapper
+  NIP:  00000000000385f4 LR: 000000000100ed00 CTR: 000000000000007f
+  REGS: c00000000110bb40 TRAP: 0200
+  MSR:  9000000000201003 <SF,HV,ME,RI,LE>  CR: 48002222  XER: 20040000
+  CFAR: 00000000000385d0 DAR: 0000000000001c00 DSISR: 00000200 SOFTE: 1
+
+If the machine check happens early in boot while we have MSR_ME=0 it
+will escalate into a checkstop and kill the box entirely.
+
+To fix it we could change the inline asm constraint to "i" which
+tells the compiler the value is a constant. But a better fix is to just
+pass a literal 1 into the macro, which bypasses any problems with inline
+asm constraints.
