menuconfig aarch64 endianess
by William Roberts
Hello,
I am an aarch64 machine and wanted to build uclibc with little endian
support. If I use menuconfig it does not allow me to take it off of
big endian, but if I manually edit the .config to little endian it
works. Seems like a bug in menuconfig, where can I report this?
Thanks

[PATCH] Makerules: fix out-of-tree build error "Argument list too long"
by Max Filippov
Make rule that announces and makes static libc archive can generate
command line that is too long when a full path O= option is used. That
breaks the build with the following message:
make: /bin/sh: Argument list too long
Use make $(file) construct to generate file list file and use that file
as $(AR) argument instead.

[PATCH] x86: Fix __libc_sigaction implementation.
by Dmitry Chestnykh
For x86 we have to copy only mask, handler and flags.
We haven't set SA_RESTORER bit in sa_flags anyway.
This patch fixes multiple test failures on x86.
Also we have to build uClibc with FP for x86 because
without FP NPTL and libgcc code cannot properly unwind
the stack during asynchronous cancellation of system calls.

[PATCH] Switch x86 NPTL impl to generic C code.
by Dmitry Chestnykh
The asm code has high maintainance cost.
The cost is extremely high if we take into
consideration time64 implementation which implies
operating with 64bit numbers on 32bit system.
Also glibc uses mainly C in NPTL code.

[PATCH 1/2] Generalize vDSO code.
by Dmitry Chestnykh
- Add macroses for vDSO functions names because
in some architectures these names differ from the default ones.
- Add header guards in dl-syscalls.h .

[PATCH] aarch64: Apply relocations to use TLS GD access model.
by Dmitry Chestnykh
In aarch64 when the general dynamic access model is used for tls data
the linker emits two dynamic relocs (R_AARCH64_TLS_DTPMOD(64) and
R_AARCH64_TLS_DTPREL(64)) that must be applied by ld.so during object
loading.
