+Subject: [PATCH 1/1] libsanitizer: Remove cyclades from libsanitizer
+
+The Linux kernel has removed the interface to cyclades from
+the latest kernel headers[1] due to them being orphaned for the
+past 13 years.
+
+libsanitizer uses this header when compiling against glibc, but
+glibcs itself doesn't seem to have any references to cyclades.
+
+Further more it seems that the driver is broken in the kernel and
+the firmware doesn't seem to be available anymore.
+
+As such since this is breaking the build of libsanitizer (and so the
+GCC bootstrap[2]) I propose to remove this.

9.3.0: cut 2 patchset

One new patch:

One old patch is split in two:
- 04_all_default-ssp-fix.patch
+ 04_all_nossp-on-nostdlib.patch
+ 27_all_default_ssp-buffer-size.patch
to separate two independent fixes.

9.3.0: increase expmed cache size from 10^3 to 10^6

Without this patch is takes dev-libs/xxhash 1-2 hours
to compile. With this patch - TODO measurements.

It workarounds deficiency of synth_mult() which evics
cache entries as it calculates optimal multiplication
algorithm. xxhash is especially hevyweight as it's a
64-bit multiplication of large prime constants.

9.3.0: split 04_all_default-ssp-fix.patch in two

No functional change should happen. gcc-10 got rid of
defaults defined in .c file. We'll need to adapt one
patch slightly.
