+available.  Tests based on a variety of T- and F-statistics (including
+T-statistics based on regression parameters from linear and survival models
+as well as those based on correlation parameters) are included.  When probing
+hypotheses with T-statistics, users may also select a potentially faster null
+distribution which is multivariate normal with mean zero and variance
+covariance matrix derived from the vector influence function.  Results are
+reported in terms of adjusted P-values, confidence regions and test statistic

+Libpfm4 helps convert from an event name, expressed as a string, to the event
+encoding that is either the raw event as documented by the hardware vendor or
+the OS-specific encoding.  In the latter case, the library is able to prepare
+the OS-specific data structures needed by the kernel to setup the event.

-Subject: [PATCH] multiboot: bss_end_addr can be zero
-
-The multiboot spec (https://www.gnu.org/software/grub/manual/multiboot/),
-section 3.1.3, allows for bss_end_addr to be zero.
-
-A zero bss_end_addr signifies there is no .bss section.
