Revert "pa: couple of tweaks based on Speedometer"This reverts commit 660e70eeacc9768978939cf8216f30a58e523c6d.Reason for revert: This seems to have caused some crashes. Seehttps://crbug.com/328875414Original change's description:> pa: couple of tweaks based on Speedometer>> Calling to madvise/mprotect is expensive on macs. This patch aims> to reduce the number of such calls. It adds the following:> . Increases empty cache index bits by 8.> . If RegisterEmpty() is called and the slot span was already> registered, don't do anything. This is in hopes of avoiding> churn if a slot-span is reused a bunch.> . Increases max_empty_slot_spans_dirty_bytes_shift by a factor of 2.> . Adds feature for that makes blink's partition for buffers use the> large empty slot span ring.>> Change-Id:I6bde3c62e1e9edd280f649ec71eb6d1bf04eb644> Reviewed-on:https://chromium-review.googlesource.com/c/chromium/src/+/5181724> Reviewed-by: Scott Violet <sky@chromium.org>> Commit-Queue: Scott Violet <sky@chromium.org>> Reviewed-by: Benoit Lize <lizeb@chromium.org>> Cr-Commit-Position: refs/heads/main@{#1270352}Bug: 328875414Change-Id:Iba537e69f2f64b35c3352368e36a762d3eea2d36Reviewed-on:https://chromium-review.googlesource.com/c/chromium/src/+/5361773Owners-Override: Daniel Yip <danielyip@google.com>Reviewed-by: Scott Violet <sky@chromium.org>Commit-Queue: Daniel Yip <danielyip@google.com>Auto-Submit: Daniel Yip <danielyip@google.com>Reviewed-by: Daniel Yip <danielyip@google.com>Cr-Commit-Position: refs/branch-heads/6351@{#4}Cr-Branched-From: a97ece83a5ff3f6f117b1ff5ce36c40ee4cbdd52-refs/heads/main@{#1270764}

For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.
