-Subject: [PATCH] util/cacheinfo: fix crash when compiling with uClibc
-
-uClibc defines _SC_LEVEL1_ICACHE_LINESIZE and _SC_LEVEL1_DCACHE_LINESIZE
-but the corresponding sysconf calls returns -1, which is a valid result,
-meaning that the limit is indeterminate.
-
-Handle this situation using the fallback values instead of crashing due
-to an assertion failure.

-Subject: [PATCH] target/arm/arm-semi: fix SYS_OPEN to return nonzero
- filehandle
-
-According to the specification "Semihosting for AArch32 and Aarch64",
-the SYS_OPEN operation should return:
-
- - A nonzero handle if the call is successful
- - -1 if the call is not successful
-
-So, it should never return 0.
-
-Prior to commit 35e9a0a8ce4b ("target/arm/arm-semi: Make semihosting
-code hand out its own file descriptors"), the guest fd matched to the
-host fd. It returned a nonzero handle on success since the fd 0 is
-already used for stdin.
-
-Now that the guest fd is the index of guestfd_array, it starts from 0.
-
-I noticed this issue particularly because Trusted Firmware-A built with
-PLAT=qemu is no longer working. Its io_semihosting driver only handles
-a positive return value as a valid filehandle.
-
-Basically, there are two ways to fix this:
-
-  - Use (guestfd - 1) as the index of guestfs_arrary. We need to insert
-    increment/decrement to convert the guestfd and the array index back
-    and forth.
-
-  - Keep using guestfd as the index of guestfs_array. The first entry
-    of guestfs_array is left unused.
-
-I thought the latter is simpler. We end up with wasting a small piece
-of memory for the unused first entry of guestfd_array, but this is
-probably not a big deal.
-
